Longitudinal course of consecutive esotropia in children following surgery for basic-type intermittent exotropia
Eye, 2021Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Purpose To evaluate the longitudinal course of consecutive esotropia following surgery for basic-type intermittent exotropia. Methods Patients who underwent surgery (bilateral lateral rectus muscle recession [BLR] or unilateral lateral rectus muscle recession–medial rectus muscle resection [RR]) for the treatment of intermittent exotropia between 2011 and 2017 with a minimum follow-up period of 2 years were retrospectively reviewed. When esodeviation occurred later in patients with orthotropia or Exodeviation at postoperative month 1, it was defined as delayed-onset consecutive esotropia. The number of patients with esodeviation at every follow-up and characteristics of patients were evaluated. Results A total of 336 patients (6.2 ± 2.1 years; 236 in the BLR group and 100 in the RR group) were included. After surgery, postoperative esodeviation decreased mostly during the 1st postoperative month in both groups. At postoperative year 2, there were 28 patients (8.3%) with consecutive esotropia: six in the RR group and 22 in the BLR group. Among the 284 patients with orthotropia or Exodeviation at postoperative month 1, there were 13 patients with delayed-onset consecutive esotropia; they presented larger preoperative angle of Exodeviation, poorer stereopsis, younger at the time of surgery and associated with the types of surgeries for exotropia. Conclusions In patients with consecutive esotropia, the angle of esodeviation decreased and patching/prismatic correction helped achieve the good surgical outcomes. However, delayed-onset consecutive esotropia and persistent esotropia also presented, requiring the reoperation. Therefore, postoperative alignment should be carefully monitored after surgery for intermittent exotropia.

Long-term outcomes of bilateral lateral rectus recession versus unilateral lateral rectus recession-medial rectus plication in children with basic type intermittent exotropia
Eye, 2019Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Purpose To compare the long-term surgical outcomes between bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus plication (RP) in intermittent exotropia. Methods Children who underwent BLR or RP for basic type intermittent exotropia between 2015 and 2016 with a minimum follow-up period of 2 years were retrospectively reviewed. Surgical outcomes were classified based on postoperative angle of deviation as follows: success (esodeviation ≤ 5 prism diopters [PD] to Exodeviation ≤ 10 PD), and failure (overcorrection [esodeviation > 5 PD] and undercorrection or recurrence [Exodeviation > 10 PD]). Results Of 144 patients, 90 underwent BLR and 54 underwent RP. The angle of Exodeviation of the RP group steadily increased over time after the surgery. The BLR group showed an earlier exodrift and a more stable course compared to the RP group. Kaplan–Meier survival analysis showed a better survival in the BLR group, with final success rates of 48.9% in the BLR group and 25.9% in the RP group after a mean follow-up of 2.2 years. Patients with a successful outcome had greater esodeviation at 1 week postoperatively (at distance 7.6 PD in the BLR group, 11.4 in the RP group). Conclusions Surgical outcomes were better in the BLR group than in the RP group. The RP group showed higher rates of recurrence of Exodeviation, while the BLR group presented a more stable course. Establishing more esodeviation at postoperative week 1 in the RP group compared to the BLR group would be required to achieve successful results.

Long-term outcomes following resection-recession versus plication-recession in children with intermittent exotropia.
The British journal of ophthalmology, 2019Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Background/Aims To compare the long-term surgical outcomes between unilateral lateral rectus recession-medial rectus resection (RR) and lateral rectus recession-medial rectus plication (RP) in children with intermittent exotropia. Methods Children who underwent RR or RP for intermittent exotropia between January 2008 and July 2016, with a minimum follow-up period of 2 years were retrospectively reviewed. Postoperative angle of deviations and clinical factors including sex, age, refractive errors, preoperative angle of deviation, types of exotropia and stereopsis were investigated. Based on the angle of deviation at year 2, surgical outcomes were classified into two groups as follows: success (esodeviation ≤5 prism dioptres (PD) to Exodeviation ≤10 PD) and failure (overcorrection (esodeviation >5 PD) and undercorrection or recurrence (Exodeviation >10 PD)). Results Of the 186 patients, 114 underwent RR and 72 underwent RP. The angle of Exodeviation steadily increased over time in both groups after surgery. The durations of exodrift were longer in the RP group than in the RR group. The surgical success at postoperative year 2 was 55.3% in the RR group and 27.8% in the RP group (p Conclusions In children with intermittent exotropia, RR group presented better surgical outcomes than RP group. The amount of initial overcorrection was important to achieve favourable outcomes in children with intermittent exotropia.

Long-term surgical outcomes of patients with consecutive exotropia
Graefe's Archive for Clinical and Experimental Ophthalmology, 2019Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Purpose To evaluate the long-term surgical outcome of patients with consecutive exotropia. Methods Patients who underwent surgery for the treatment of consecutive exotropia between January 2008 and July 2016 with a minimum follow-up period of 2 years were retrospectively reviewed. Surgical outcomes were classified based on postoperative angle of deviation at 2 years as follows: success (esodeviation ≤ 5 prism diopters [PD] to Exodeviation ≤ 10 PD), and recurrence [Exodeviation > 10 PD]). Postoperative angles of deviation at 1 week, 1 month, 6 months, 1 year, and 2 years and at the final follow-up were investigated. Results A total of 37 patients (28 in the success group and 9 in the recurrence group) were included. Surgical success rate at 2 years was 75.7%, and reoperation rate was 10.8% during a mean follow-up period of 42.4 ± 18.3 months after consecutive exotropia surgery. After surgery, exodrift occurred mostly during 1-month follow-up in both groups, and those with no exodrift within 1 month presented a higher surgical success. Thereafter, patients in the success group showed a more stable course during follow-up than those in the recurrence group. Stereopsis was an important factor associated with surgical outcome. Conclusions Exodrift occurs mostly within 1 month after surgery for consecutive exotropia. Targeting initial overcorrection and establishing esodeviation at postoperative month 1 is important to achieve successful results.

Surgical outcomes of intermittent exotropia according to exotropia type based on distance/near differences
2019Co-Authors: Gi Hyun Bae, Seok Hyun Bae, Dong Gyu ChoiAbstract:We compare the surgical outcomes of intermittent exotropia of the basic, pseudo-divergence excess (pseudo-DE) and true divergence excess (true DE) types. A study was performed with 342 patients who had undergone surgery for intermittent exotropia of the basic, pseudo-DE or true DE type with a postoperative follow-up period of 6 months or more. The main outcome measures were postoperative angles of deviation at distance and near, and surgical success rates. Surgical success was defined as alignment between Exodeviation of 10 PD and esodeviation of 5 PD at distance and near. Additionally, survival curves of recurrence were analyzed by the Kaplan-Meier method. The postoperative angles of deviation at both distance and near in pseudo-DE type were significantly smaller than those in basic type at the final examination (p = 0.003,

PloS one, 2018Co-Authors: Seok Hyun Bae, Key Hwan Lim, Ji-soo Kim, Ah Young Kim, Joo Yeon Lee, Mi-young Choi, Dong Gyu ChoiAbstract:Purpose To determine whether the inferior oblique (IO) muscle weakening procedure combined with exotropia surgery affects the surgical correction of exotropia. Design Institutional, retrospective study. Methods We retrospectively reviewed the medical records of 310 patients who had undergone exotropia-correcting surgery combined with IO weakening (group A, 64 patients) or without IO weakening (group B, 246) with a postoperative follow-up of 6 months or more. The main outcome measures were the postoperative mean angle of horizontal deviation, the success rate, and the overcorrection rate. Surgical success was defined as an alignment between 10 prism diopters (PD) of Exodeviation and 5 PD of esodeviation. Results The postoperative mean angles of Exodeviation, throughout the follow-up period, did not significantly differ between the groups. Although the surgical success rate was higher in group B at postoperative 1 month (p = 0.035), there was no statistical difference between the 2 groups from postoperative 6 months.: The final success rates were 56.3 and 51.6% (p = 0.509). The overcorrection rate was significantly higher in group A at postoperative 1, 6 and 24 months (p = 0.017, p = 0.028, p = 0.030, respectively); however, at the final follow-up, there was no overcorrection in either group. Conclusion The overcorrection rate was higher in group A until postoperative 2 years, even though the mean angles of Exodeviation and the success rates did not significantly differ between the 2 groups. Surgeons should be mindful of overcorrection when planning exotropia surgery combined with the IO weakening procedure.

Graefe's Archive for Clinical and Experimental Ophthalmology, 2018Co-Authors: Seok Hyun Bae, Key Hwan Lim, Joo Yeon Lee, Mi-young Choi, Young Bok Lee, Soolienah Rhiu, Dong Gyu ChoiAbstract:Purpose To evaluate the early postoperative changes of the angle of deviation after surgery for intermittent exotropia. Methods We retrospectively reviewed the medical records of 114 patients who had been surgically treated for intermittent exotropia and followed-up on postoperatively for 1 month or more. Patients were observed at postoperative 6 h, 1 day, 1 week, and 1 month. The main outcome measure was the change of the angle of deviation during the early postoperative period (from 6 h to 1 day postoperatively). Results The mean preoperative angle of Exodeviation was 26.3 ± 7.6 PD at distance and 25.4 ± 10.3 PD at near. The angle of deviation was −3.3 (esodeviation) ± 7.0 PD at distance and −0.7 ± 7.1 PD at near at postoperative 6 h, and −3.7 ± 6.9 PD and −0.8 ± 6.8 PD at postoperative 1 day. Neither of these sets represented a significant change from 6 h to 1 day postoperatively ( p = 0.300 at distance, p = 0.945 at near). However, in 25 patients (21.9%) the angle of deviation changed 5 PD or more from 6 h to 1 day. Among them, ten showed exodrift and 15 esodrift. At postoperative 1 month, the deviations became significantly more exotropic compared with postoperative 1 day ( p

Faden operation in consecutive esotropia
Eye, 2019Co-Authors: Min-jung Kim, Seung Hyun KimAbstract:Purpose To evaluate the efficacy of Faden procedure for correcting consecutive esotropia (ET). Methods This retrospective study included 25 children who developed consecutive ET after primary bilateral lateral rectus (BLR) recession and underwent medial rectus (MR) recession with the Faden procedure (Faden group) or MR recession only (control group) between 2013 and 2018. Postoperative deviation angles were evaluated at each follow-ups until postoperative 6-month visit. Surgical motor and sensory outcomes were compared between Faden group and control group. Results There were 10 children in the Faden group and 15 children in the control group. While the Faden group maintained orthotropia without any small deviation until postoperative 6-month visit, the control group showed wider distribution of postoperative deviation angles (1 patient with small angle esodeviation < 5 PD, 3 patients with esodeviation > 5 PD, and 3 patients with Exodeviation < 5 PD). In the Faden group, seven patients have good stereopsis (60″ or better) and three patients demonstrated fair stereopsis (80–3000″) after surgery. In the control group, four, eight, and three patients showed good, fair, and nil stereopsis ( P = 0.026), respectively. Conclusion MR recession combined with Faden operation could be a good surgical option for managing consecutive ET.

Esodeviation without correction for tapering hyperopia in refractive accommodative esotropia.
Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 2018Co-Authors: Young-woo Suh, Seung Hyun KimAbstract:Abstract Objective To investigate clinical features for prescription of tapered hyperopia in patients with refractive accommodative esotropia (RAET). Methods The clinical features in patients with RAET who began tapering of hyperopia were analyzed. Within a range that can sustain corrected visual acuity and stereoacuity, patients were prescribed for tapered hyperopic correction by 0.25-diopters (D) interval, up to a maximum of 1.0 D. At every visit, visual acuity and esodeviation with and without correction, amount of tapered hyperopia, and near stereoacuity were measured. Results One hundred and six patients were enrolled in this study. The follow-up period was 3.1 ± 0.2 years and frequency of visits was 6.3 ± 0.6. Tapering hyperopia was initiated at 6.1 ± 2.9 years, and baseline refraction was 7.6 ± 1.5 D. The esodeviation without correction was 24.3 ± 8.5 prism diopters (PD), and median near stereoacuity was 400 arc sec. The median amount of tapered hyperopia at visit was 0.5 D. At the final visit, there were no significant deteriorations in visual acuity, esodeviation with correction, or near stereoacuity (p > 0.05, all). The amount of tapered hyperopia was positively correlated with correction and the reduced esodeviation without correction (p = 0.03). Conclusions Esodeviation without correction should be considered for tapering hyperopia for patients with RAET. Esodeviation without correction can be easily measured, and its decline may be used as a clinical indicator for tapering hyperopia.

PloS one, 2018Co-Authors: Kyung Eun Han, Seung Hyun Kim, Seung-hee Baek, Key Hwan LimAbstract:Purpose To evaluate the prevalence and risk factors associated with horizontal strabismus in children and adolescents in South Korea. Methods A total of 5,935 children and adolescents 5-18 years of age who participated in the fourth and fifth Korean National Health and Nutrition Examination Survey (KNHANES IV-V) from July 2008 to December 2011 were evaluated and the prevalence of horizontal strabismus was estimated. Univariate and multivariate logistic regression analyses were conducted to determine the association between demographic, socioeconomic and clinical risk factors and clinically significant Exodeviation (≥15 prism diopters [PD]) and esodeviation (≥10 PD). Results Among 5,935 eligible subjects, 84 subjects had clinically significant Exodeviation and 13 had clinically significant esodeviation. The overall prevalence of clinically significant horizontal strabismus was 1.6% (95% confidence interval [CI], 1.2-2.1): 1.3% (95% CI, 1.0-1.7) for clinically significant Exodeviation and 0.3% (95% CI, 0.1-0.6) for clinically significant esodeviation. Clinically significant Exodeviation was associated with amblyopia (adjusted odds ratio [aOR], 6.45; 95% CI, 2.14-19.44), family history of strabismus (aOR, 4.91; 95% CI, 1.71-14.08) and astigmatism ≥1.0 D (aOR, 1.84; 95% CI, 1.13-2.98). Clinically significant esodeviation was associated with hyperopia (aOR, 12.16; 95% CI, 1.31-113.04) and amblyopia (aOR, 4.70; 95% CI, 1.12-19.81). Other demographic, socioeconomic, and clinical variables were not associated with strabismus. Conclusion This study provides data on the prevalence and independent risk factors for clinically significant Exodeviation and esodeviation in a representative population of children and adolescents in South Korea.

Longitudinal course of consecutive esotropia in children following surgery for basic-type intermittent exotropia
Eye, 2021Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Purpose To evaluate the longitudinal course of consecutive esotropia following surgery for basic-type intermittent exotropia. Methods Patients who underwent surgery (bilateral lateral rectus muscle recession [BLR] or unilateral lateral rectus muscle recession–medial rectus muscle resection [RR]) for the treatment of intermittent exotropia between 2011 and 2017 with a minimum follow-up period of 2 years were retrospectively reviewed. When esodeviation occurred later in patients with orthotropia or Exodeviation at postoperative month 1, it was defined as delayed-onset consecutive esotropia. The number of patients with esodeviation at every follow-up and characteristics of patients were evaluated. Results A total of 336 patients (6.2 ± 2.1 years; 236 in the BLR group and 100 in the RR group) were included. After surgery, postoperative esodeviation decreased mostly during the 1st postoperative month in both groups. At postoperative year 2, there were 28 patients (8.3%) with consecutive esotropia: six in the RR group and 22 in the BLR group. Among the 284 patients with orthotropia or Exodeviation at postoperative month 1, there were 13 patients with delayed-onset consecutive esotropia; they presented larger preoperative angle of Exodeviation, poorer stereopsis, younger at the time of surgery and associated with the types of surgeries for exotropia. Conclusions In patients with consecutive esotropia, the angle of esodeviation decreased and patching/prismatic correction helped achieve the good surgical outcomes. However, delayed-onset consecutive esotropia and persistent esotropia also presented, requiring the reoperation. Therefore, postoperative alignment should be carefully monitored after surgery for intermittent exotropia.

Eye, 2019Co-Authors: Haeng Jin Lee, Seong Joon KimAbstract:Purpose To compare the long-term surgical outcomes between bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus plication (RP) in intermittent exotropia. Methods Children who underwent BLR or RP for basic type intermittent exotropia between 2015 and 2016 with a minimum follow-up period of 2 years were retrospectively reviewed. Surgical outcomes were classified based on postoperative angle of deviation as follows: success (esodeviation ≤ 5 prism diopters [PD] to Exodeviation ≤ 10 PD), and failure (overcorrection [esodeviation > 5 PD] and undercorrection or recurrence [Exodeviation > 10 PD]). Results Of 144 patients, 90 underwent BLR and 54 underwent RP. The angle of Exodeviation of the RP group steadily increased over time after the surgery. The BLR group showed an earlier exodrift and a more stable course compared to the RP group. Kaplan–Meier survival analysis showed a better survival in the BLR group, with final success rates of 48.9% in the BLR group and 25.9% in the RP group after a mean follow-up of 2.2 years. Patients with a successful outcome had greater esodeviation at 1 week postoperatively (at distance 7.6 PD in the BLR group, 11.4 in the RP group). Conclusions Surgical outcomes were better in the BLR group than in the RP group. The RP group showed higher rates of recurrence of Exodeviation, while the BLR group presented a more stable course. Establishing more esodeviation at postoperative week 1 in the RP group compared to the BLR group would be required to achieve successful results.

Postoperative angles of deviation at 1 week, 1 month, 6 months, 1 year, and 2 years and at the final follow-up were investigated. Results A total of 37 patients (28 in the success group and 9 in the recurrence group) were included. Surgical success rate at 2 years was 75.7%, and reoperation rate was 10.8% during a mean follow-up period of 42.4 ± 18.3 months after consecutive exotropia surgery. After surgery, exodrift occurred mostly during 1-month follow-up in both groups, and those with no exodrift within 1 month presented a higher surgical success. Thereafter, patients in the success group showed a more stable course during follow-up than those in the recurrence group. Stereopsis was an important factor associated with surgical outcome. Conclusions Exodrift occurs mostly within 1 month after surgery for consecutive exotropia. Targeting initial overcorrection and establishing esodeviation at postoperative month 1 is important to achieve successful results.

Surgical outcomes of intermittent exotropia according to exotropia type based on distance/near differences
2019Co-Authors: Gi Hyun Bae, Seok Hyun Bae, Dong Gyu ChoiAbstract:We compare the surgical outcomes of intermittent exotropia of the basic, pseudo-divergence excess (pseudo-DE) and true divergence excess (true DE) types. A study was performed with 342 patients who had undergone surgery for intermittent exotropia of the basic, pseudo-DE or true DE type with a postoperative follow-up period of 6 months or more. The main outcome measures were postoperative angles of deviation at distance and near, and surgical success rates. Surgical success was defined as alignment between Exodeviation of 10 PD and esodeviation of 5 PD at distance and near. Additionally, survival curves of recurrence were analyzed by the Kaplan-Meier method. The postoperative angles of deviation at both distance and near in pseudo-DE type were significantly smaller than those in basic type at the final examination (p = 0.003,

Effect of combining inferior oblique muscle weakening procedures with exotropia surgery on the surgical correction of exotropia.
PloS one, 2018Co-Authors: Seok Hyun Bae, Key Hwan Lim, Ji-soo Kim, Ah Young Kim, Joo Yeon Lee, Mi-young Choi, Dong Gyu ChoiAbstract:Purpose To determine whether the inferior oblique (IO) muscle weakening procedure combined with exotropia surgery affects the surgical correction of exotropia. Design Institutional, retrospective study. Methods We retrospectively reviewed the medical records of 310 patients who had undergone exotropia-correcting surgery combined with IO weakening (group A, 64 patients) or without IO weakening (group B, 246) with a postoperative follow-up of 6 months or more. The main outcome measures were the postoperative mean angle of horizontal deviation, the success rate, and the overcorrection rate. Surgical success was defined as an alignment between 10 prism diopters (PD) of Exodeviation and 5 PD of esodeviation. Results The postoperative mean angles of Exodeviation, throughout the follow-up period, did not significantly differ between the groups. Although the surgical success rate was higher in group B at postoperative 1 month (p = 0.035), there was no statistical difference between the 2 groups from postoperative 6 months.: The final success rates were 56.3 and 51.6% (p = 0.509). The overcorrection rate was significantly higher in group A at postoperative 1, 6 and 24 months (p = 0.017, p = 0.028, p = 0.030, respectively); however, at the final follow-up, there was no overcorrection in either group. Conclusion The overcorrection rate was higher in group A until postoperative 2 years, even though the mean angles of Exodeviation and the success rates did not significantly differ between the 2 groups. Surgeons should be mindful of overcorrection when planning exotropia surgery combined with the IO weakening procedure.

Graefe's Archive for Clinical and Experimental Ophthalmology, 2018Co-Authors: Seok Hyun Bae, Key Hwan Lim, Joo Yeon Lee, Mi-young Choi, Young Bok Lee, Soolienah Rhiu, Dong Gyu ChoiAbstract:Purpose To evaluate the early postoperative changes of the angle of deviation after surgery for intermittent exotropia. Methods We retrospectively reviewed the medical records of 114 patients who had been surgically treated for intermittent exotropia and followed-up on postoperatively for 1 month or more. Patients were observed at postoperative 6 h, 1 day, 1 week, and 1 month. The main outcome measure was the change of the angle of deviation during the early postoperative period (from 6 h to 1 day postoperatively). Results The mean preoperative angle of Exodeviation was 26.3 ± 7.6 PD at distance and 25.4 ± 10.3 PD at near. The angle of deviation was −3.3 (esodeviation) ± 7.0 PD at distance and −0.7 ± 7.1 PD at near at postoperative 6 h, and −3.7 ± 6.9 PD and −0.8 ± 6.8 PD at postoperative 1 day. Neither of these sets represented a significant change from 6 h to 1 day postoperatively ( p = 0.300 at distance, p = 0.945 at near). However, in 25 patients (21.9%) the angle of deviation changed 5 PD or more from 6 h to 1 day. Among them, ten showed exodrift and 15 esodrift. At postoperative 1 month, the deviations became significantly more exotropic compared with postoperative 1 day ( p
