bilateral familial duane s retraction syndrome
Optometry - Journal of The American Optometric Association, 2007Co-Authors: Lily Y Zhutam, Andrew S GurwoodAbstract:Abstract Background Duane’s retraction syndrome (DRS) is a congenital oculomotor anomaly that is accompany by globe retraction with simultaneous narrowing of the Palpebral Fissure on attempted adduction. Hereditary factors have been postulated to be associated with the development of DRS since 1879. However, the modern literature fails to provide substantial scientific evidence to support this premise. Case report A 7-year-old patient presented with bilateral abduction deficit and retraction of the globe with narrowing of the Palpebral Fissure on attempted adduction. Conclusion We present a case of Duane’s retraction syndrome in which an investigation of the family history uncovered 4 generations of affected family members, lending support to the theory that some cases of DRS are inherited.

duane s retraction syndrome literature review
Optometry - Journal of The American Optometric Association, 2000Co-Authors: Andrew S Gurwood, Christine A TerrignoAbstract:Background Duane's retraction syndrome (DRS), also known as Stilling-Turk-Duane syndrome, is defined as a congenital miswiring of the lateral and medial recti muscles, resulting in an impaired ocular motility syndrome that includes Palpebral Fissure narrowing. The incidence of DRS is approximately 1% of the total cases of strabismus. Eighty percent of cases are unilateral and characterized by either limited abduction, limited adduction, or both. Case report A 21-year-old man came to the clinic for a routine ocular examination without symptoms. A review of the history uncovered the presence of congenital, type I Duane's retraction syndrome. The examination demonstrated orthophoria in primary gaze, an abduction deficit O.S., and left globe retraction with Palpebral Fissure narrowing on right gaze O.S. Management In most cases of DRS the eyes are straight in primary position and there is no amblyopia. Amblyopia, when present, is usually the result of anisometropia and not strabismus. Because our patient had no symptoms of diplopia in primary gaze (orthophoria) or in attempted right gaze (due to suppression of the left eye with abduction), prismatic and/or surgical management were not indicated, since the patient was free from binocular and cosmetic abnormalities. Conclusion DRS is characterized by abnormal development of the cells in the abducens nucleus (CN VI), resulting in restricted or absent abduction and erroneous innervation of the lateral rectus by branches emanating from oculomotor nuclei (CN III). Management may include orthoptics, surgery, or monitoring.

Increased levator muscle function by supramaximal resection in patients with blepharophimosis-ptosis-epicanthus inversus syndrome
'American Medical Association (AMA)', 2011Co-Authors: Decock Christian, Shah, Akash D, Delaey Christophe, Forsyth Ramses, Bauters Wouter, Kestelyn Philippe, De Baere Elfride, Claerhout IlseAbstract:Objective: To study the efficacy and clinical and anatomical results of supramaximal levator resection in patients with blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) with severe congenital ptosis with poor levator function (LF). Methods: Eleven patients with molecularly proven BPES underwent supramaximal levator resection. Palpebral Fissure height and LF were measured preoperatively and postoperatively. Results: All patients showed an excellent reduction in ptosis with a single intervention resulting in a clear visual axis. Palpebral Fissure height improved from mean (SD) 3.3 (0.7) mm preoperatively to 7.1 (0.9) mm postoperatively (P value < .001). Four patients underwent additional surgery because of cosmetic issues with eyelid height asymmetry. All patients showed a marked, consistent, and lasting improvement in LF, going from mean (SD) 1.9 (0.9) mm preoperatively to 7.4 (1.1) mm postoperatively (P value < .001). This improvement could be attributed to the presence of a very long and thin tendon, as well as a striated muscle belly. This elongated aponeurosis inhibits the levator muscle from having sufficient impact on the vertical eyelid excursion. Conclusions: We demonstrated that supramaximal levator resection performed in patients with BPES not only results in good cosmetic appearance in terms of ptosis reduction in the majority of cases but also in a significant increase of the levator palpebrae superioris function. An anatomical substrate was found to explain these findings. To our knowledge, this is the first study to provide evidence of a marked increase in LF in BPES due to resection of the elongated tendon with reinsertion of the muscle belly

Cosmetic Lateral Canthoplasty: Preserving the Lateral Canthal Angle
Archives of plastic surgery, 2016Co-Authors: Yeon Jun Kim, Kyu Ho Lee, Hong Lim Choi, Eui Cheol JeongAbstract:Cosmetic lateral canthoplasty, in which the size of the eye is increased by extending the Palpebral Fissure and decreasing the degree of the eye slant, has become a prevalent procedure for East Asians. However, it is not uncommon for there to be complications or unfavorable results after the surgery. With this in mind, the authors have designed a surgical method to reduce complications in cosmetic lateral canthoplasty by preserving the lateral canthal angle. We discuss here the anatomy required for surgery, the surgical methods, and methods for reducing complications during cosmetic lateral canthoplasty.

Cosmetic Lateral Canthoplasty: Lateral Canthoplasty to Lengthen the Lateral Canthal Angle and Correct the Outer Tail of the Eye.
Archives of plastic surgery, 2016Co-Authors: Soo Wook Chae, Byung Min YunAbstract:There are many women who want larger and brighter eyes that will give a favorable impression. Surgical methods that make the eye larger and brighter include double eyelidplasty, epicanthoplasty, as well as lateral canthoplasty. Double eyelidplasty produces changes in the vertical dimension of the eyes, whereas epicanthoplasty and lateral canthoplasty create changes in the horizontal dimension of the eyes. Epicanthoplasty, a surgical procedure which enlarges the eye horizontally, is performed at the inner corner of the eye, whereas lateral canthoplasty enlarges the outer edge of the eye. In particular, if the slant of the Palpebral Fissure is raised and the horizontal dimension of the Palpebral Fissure is short, adjusting the slant of the Palpebral Fissure through lateral canthoplasty can achieve an enlargement of eye width and smoother features. Depending on the patient's condition, even better results can be achieved if this procedure is performed in conjunction with other procedures, such as double eyelidplasty, epicanthoplasty, eye roll formation surgery, fat graft, and facial bone contouring surgery. In this paper, the authors will introduce in detail their surgical method for a cosmetic lateral canthoplasty that lengthens the lateral canthal angle and corrects the outer tail of the eyes, in order to ease the unfavorable impression.
