  • Pars plana vitrectomy with peripheral Retinotomy after injection of preoperative intravitreal tissue plasminogen activator: a modified procedure to drain massive subretinal haemorrhage
    The British journal of ophthalmology, 2006
    Co-Authors: Yusuke Oshima, Masahito Ohji, Yasuo Tano
    Abstract:

    Aims: To report outcome of a modified procedure for draining massive subretinal haemorrhages (SRHs). Methods: The charts of eight consecutive eyes from eight patients with massive SRHs extending to the periphery and involving two or more quadrants with haemorrhagic and bullous retinal detachment were reviewed. Tissue plasminogen activator (tPA) was injected intravitreally 12–24 h preoperatively; vitrectomy was carried out with peripheral Retinotomy, drainage of the SRH from the Retinotomy using perfluorocarbon liquid and gas tamponade with prone positioning postoperatively. Results: The preoperative visual acuities ranged from light perception to 20/200. Most of the subretinal haematomas moved postoperatively to the vitreous cavity through the peripheral Retinotomy using perfluorocarbon liquid. Residual SRHs were drained from the anterior chamber at the bedside after prone positioning overnight. SRH recurred in one eye 14 months postoperatively and was successfully retreated. No other serious complications developed. The final visual acuity improved in seven eyes (range 20/1000–20/60). Polypoidal lesions in choroidal vasculatures were present in three of seven patients. Conclusions: The technique seems safe and effective for treating massive SRH. However, visual recovery is limited by the underlying macular pathology. Polypoidal choroidal vasculopathy, other than age-related macular degeneration, may be another cause of massive SRHs.

    Abstract:

    Abstract Purpose To determine the morphologic and functional changes of the fovea and retina of monkey eyes after macular translocation with 360-degree Retinotomy. Design Experimental study. Methods The retinas of eight monkey eyes were surgically translocated with a 360-degree Retinotomy with procedures similar to those used on human eyes. At 1, 2, and 3 months after the surgery, the six eyes that had successful surgery were studied by light and transmission electron microscopy, terminal deoxynucleotidyl transferase (TdT)-dNTP terminal nick-end labeling (TUNEL) assay, and immunohistochemistry with peanut agglutinin (PNA) lectin and glial fibrillary acidic protein (GFAP). Retinal physiology was assessed by scotopic and photopic electroretinograms (ERGs). Results The fovea was successfully translocated approximately 30 to 40 degrees superiorly in six eyes. The translocated macula and fovea had a normal layered architecture with no TUNEL-positive cells, minimal misalignment of the outer segments, and strong immunoreactivity to GFAP. The mean amplitudes of the scotopic and photopic b-waves were significantly reduced at 1 month after the surgery, and there was only a slight recovery at 3 months. No significant changes were observed in the mean implicit times after the surgery. Conclusion These findings indicate that macular translocation surgery with 360-degree Retinotomy results in minimal morphologic alterations but significant depression of electrophysiologic function.

    Abstract:

    Abstract PURPOSE: To report reading ability using a standardized reading chart after macular translocation with 360-degree Retinotomy in eyes with age-related macular degeneration (AMD) or with myopic choroidal neovascularization (mCNV). DESIGN: Interventional case series. METHODS: In 34 eyes of 34 patients with subfoveal choroidal neovascular membrane (AMD, 23; mCNV, 11), macular translocation surgery with 360-degree Retinotomy and simultaneous extraocular muscle surgery were performed. The average age was 67.4 ± 7.9 years, and the average follow-up period was 7.6 ± 3.3 months. The best-corrected far visual acuity (FVA) was measured with a standardized visual acuity chart using Landolt Cs, and the critical print size (CPS) was determined with the Japanese version of the Minnesota reading chart (MNREAD-J Chart) preoperatively and postoperatively. Preoperative and postoperative change in the CPS was compared with the subjective visual improvement as assessed by a questionnaire. RESULTS: The postoperative improvement of FVA was statistically significant in eyes with mCNV ( P = .010) but not significant in eyes with AMD ( P = .495). The postoperative improvement of CPS was statistically significant both in eyes with AMD ( P = .027) and in eyes with mCNV ( P = .004). The subjective visual improvement was significantly correlated with the change of CPS in patients after a second better eye surgery. CONCLUSIONS: After macular translocation with 360-degree Retinotomy, the improvement of reading ability was significant in eyes with both AMD and mCNV. We conclude that this surgical method is well suited to improve reading ability of patients with AMD or mCNV.

    Abstract:

    Purpose: To assess the effect of simultaneous oblique muscle surgery during foveal translocation surgery with 360° Retinotomy in patients with neovascular maculopathy. Methods: Foveal translocation with 360° Retinotomy was performed on 31 eyes of 31 patients with neovascular maculopathy (21 with age-related macular degeneration 9 with myopic neovascular maculopathy, and 1 with idiopathic neovascular maculopathy). All eyes had simultaneous torsional muscle surgery with recession of the superior oblique muscle and tucking of the inferior oblique muscle. Visual acuity, binocular vision, and degree of cyclotorsion were assessed pre- and postoperatively. The angles of retinal and global rotation, distance of foveal shift, and surgical complications were also investigated. Results: With a mean postoperative follow-up of 10.0 months, vision improved (>0.2 log MAR units) in 13 eyes, was unchanged in 9 eyes, and worsened (>0.2 log MAR units) in 9 eyes. Ten of 31 eyes (32%) had a final visual acuity of 20/50 or better. Eleven patients had binocular fusion, 13 patients showed suppression, and 7 patients developed diplopia that was managed by spectacles with prisms or by secondary muscle surgery. The mean retinal and global rotations were 30.3° and 23.7°, respectively. The average size of the choroidal neovascular membrane was 1.3 disc diameters (DD), while the average shift of the fovea was 1.5 DD. After the primary surgery, six eyes developed retinal detachment, two eyes macular hole, and three eyes proliferative vitreoretinopathy. These complications were successfully managed by additional surgery. Conclusion: Foveal translocation with 360° Retinotomy is effective in restoring vision in 40% of patients with neovascular maculopathy. Simultaneous oblique muscle surgery was effective in rotating the globe by about 20°, corresponding to to a foveal shift of 1.5 DD. While the development of torsional diplopia is generally prevented by simultaneous oblique muscle surgery, the relatively high incidence of surgical complications with this procedure should be taken into account.

    Abstract:

    Abstract PURPOSE: To report the results of three methods of foveal translocation in the presence of subfoveal choroidal neovascular membrane resulting from age-related macular degeneration. METHODS: We treated 51 eyes of 51 consecutive patients with subfoveal choroidal neovascular membranes resulting from age-related macular degeneration with one of three techniques of foveal translocation surgery: foveal translocation with partial Retinotomy (n = 6), limited translocation (n = 9), and translocation with 360-degree Retinotomy (n = 36). All patients were followed for at least 6 months postoperatively. The size of the choroidal neovascular membrane and the amount of foveal displacement, the best-corrected visual acuity, and complications were recorded preoperatively and postoperatively. RESULTS: The mean distance of the foveal translocation was greater in the 360-degree Retinotomy group (3340 μm) than in the partial Retinotomy (1060 μm, P P CONCLUSIONS: A significant number of patients improved or maintained best-corrected visual acuity after translocation with 360-degree Retinotomy, and limited translocation, whereas translocation with 360-degree Retinotomy is suitable for larger choroidal neovascular membranes because it resulted in the greatest foveal displacement among the three translocation procedures.

    Abstract:

    Abstract PURPOSE: To assess functional and anatomical outcomes after foveal translocation with 360-degree Retinotomy and simultaneous torsional muscle surgery in patients with myopic neovascular maculopathy. METHODS: Foveal translocation with 360-degree Retinotomy was performed in 11 eyes of 11 patients with myopic neovascular maculopathy. Ten eyes had simultaneous torsional muscle surgery with recession of the superior oblique muscle and tucking of the inferior oblique muscle. Silicone oil removal with or without intraocular lens implantation was performed 2 to 8 weeks after the primary procedure. Visual acuity, binocular function, and degree of cyclotorsion were assessed preoperatively and postoperatively. Angles of retinal and globe rotation, distance of foveal shift, and surgical complications were also investigated. RESULTS: With a mean postoperative follow-up of 6.2 months (range, 3 to 13 months), vision improved (greater than 0.2 logarithm of minimal angle of resolution [logMAR] units) in eight eyes, was unchanged in two eyes, and worsened (greater than 0.2 logMAR units) in 1 eye. Seven of 11 eyes (64%) had a final visual acuity of 20/50 or better. Five patients developed or maintained binocular fusion, four patients continued to have suppression, and two patients developed diplopia that was managed by spectacles with Fresnel prisms. Subjective cyclotorsion was less than 8 degrees in 10 eyes. Mean retinal and globe rotations were 23.4 degrees and 19.8 degrees, respectively. Average size of the choroidal neovascular membrane was 0.8 disk diameter, whereas the average distance of foveal shift was 1.5 disk diameter. After the primary procedure, three eyes developed retinal detachment, one eye macular hole, and one eye proliferative vitreoretinopathy. These complications were successfully managed by additional surgery. CONCLUSION: Foveal translocation with 360-degree Retinotomy is effective in restoring vision in some patients with myopic neovascular maculopathy. Although the development of torsional diplopia is generally obviated by simultaneous extraocular muscle surgery, a relatively high incidence of surgical complications should be taken into account with this procedure.

    Abstract:

    Abstract PURPOSE: To compare the visual outcome after foveal translocation by scleral shortening and that after 360° Retinotomy with extraocular muscle surgery in a patient with bilateral myopic neovascular maculopathy. METHODS: Case report. RESULTS: A 52-year-old woman with bilateral myopic neovascular maculopathy underwent foveal translocation with scleral shortening in the left eye, and visual acuity improved from 20/70 to 20/30. However, choroidal neovascularization recurred, and the final visual acuity was 20/40 after excision of the choroidal neovascularization. Foveal translocation with 360° Retinotomy was performed on the right eye, and visual acuity improved from 20/150 to 20/30. The critical print size was better, and the retinal sensitive area was larger in the right eye. CONCLUSION: The better reading ability shown by foveal translocation by a 360° Retinotomy compared with scleral shortening may stem from a larger retinal sensitive area obtained by this method.

    Abstract:

    Purpose: To assess the effect of simultaneous oblique muscle surgery during foveal translocation surgery with 360° Retinotomy in patients with neovascular maculopathy. Methods: Foveal translocation with 360° Retinotomy was performed on 31 eyes of 31 patients with neovascular maculopathy (21 with age-related macular degeneration 9 with myopic neovascular maculopathy, and 1 with idiopathic neovascular maculopathy). All eyes had simultaneous torsional muscle surgery with recession of the superior oblique muscle and tucking of the inferior oblique muscle. Visual acuity, binocular vision, and degree of cyclotorsion were assessed pre- and postoperatively. The angles of retinal and global rotation, distance of foveal shift, and surgical complications were also investigated. Results: With a mean postoperative follow-up of 10.0 months, vision improved (>0.2 log MAR units) in 13 eyes, was unchanged in 9 eyes, and worsened (>0.2 log MAR units) in 9 eyes. Ten of 31 eyes (32%) had a final visual acuity of 20/50 or better. Eleven patients had binocular fusion, 13 patients showed suppression, and 7 patients developed diplopia that was managed by spectacles with prisms or by secondary muscle surgery. The mean retinal and global rotations were 30.3° and 23.7°, respectively. The average size of the choroidal neovascular membrane was 1.3 disc diameters (DD), while the average shift of the fovea was 1.5 DD. After the primary surgery, six eyes developed retinal detachment, two eyes macular hole, and three eyes proliferative vitreoretinopathy. These complications were successfully managed by additional surgery. Conclusion: Foveal translocation with 360° Retinotomy is effective in restoring vision in 40% of patients with neovascular maculopathy. Simultaneous oblique muscle surgery was effective in rotating the globe by about 20°, corresponding to to a foveal shift of 1.5 DD. While the development of torsional diplopia is generally prevented by simultaneous oblique muscle surgery, the relatively high incidence of surgical complications with this procedure should be taken into account.
