Macular hole following successful stage 4B/stage 5 retinopathy of prematurity surgery

To report three eyes surgically managed for stage 4B/stage 5 retinopathy of prematurity (ROP) with successful retinal reattachment resulting in macular hole formation after 2–3 months. One patient was observed, and two patients underwent membrane dissection and silicone oil injection and maintained attached retina at last follow-up. The case series is novel to present internal limiting membrane peeling around macular hole with hole closure in one patient which is hitherto not reported. Two of the three eyes received intravitreal bevacizumab injection for aggressive posterior ROP before surgical intervention.

Surgical outcomes of immediate sequential bilateral vitreoretinal surgery for advancing retinopathy of prematurity

Purpose: Bilateral eye surgery in the same session may be required for advancing stage 4 retinopathy of prematurity (ROP). The purpose of this study was to evaluate the outcomes of immediate sequential bilateral vitreoretinal surgery (ISBVS) in stage 4 ROP. Methods: In a retrospective interventional study at a tertiary care center, 60 eyes of 30 infants who underwent ISBVS for stage 4 ROP between December 2015 and May 2017 were studied. In cases with clear retrolental access, 25G or 27G lens sparing vitrectomy (LSV) was performed and in the rest 25G lensectomy with vitrectomy (LV) was performed through clear corneal entries. The final anatomical outcome measures were the status of tractional retinal detachment (TRD) and macular status. Results: The mean gestational age was 28.4 ± 2.0 weeks and birth weight was 1214.5 ± 329.7gms. The mean postconceptional age at surgery was 40.8 ± 2.2 weeks. Stages 4a and 4b were present in 86.7% and 13.3% eyes respectively. LSV was performed in 95% eyes whereas LV was performed in the rest. None of the eyes developed lens touch, choroidal hemorrhage, postoperative hypotony, corneal decompensation, or endophthalmitis. At last follow-up (mean 45 weeks, range 20–68 weeks), macula was attached in 90% eyes with the TRD resolved completely in 61.7% eyes and significantly decreased in another 25% eyes. Sequalae included macular drag, epiretinal membrane, and progression to fibrotic stage 5 disease. Conclusion: ISBVS is safe and effective for bilateral stage 4 ROP and should be recommended in rapidly progressive cases.

Myopic Shift and Cataract Change after Lens Sparing Vitrectomy in Patients with Idiopathic Epiretinal Membrane in Their 5th and 6th Decade

PURPOSE: To determine the myopic shift and cataract change after lens sparing vitrectomy (LSV) in patients with idiopathic epiretinal membrane (ERM) in their 5th and 6th decade of life. METHODS: The medical records of patients undergoing LSV for idiopathic ERM from 2008 to 2012 were reviewed. Patients with previous intraocular surgery, preoperative significant cataract, under 40 or over 60 years of age and a follow-up period of less than 6 months were excluded. The change in refractive errors, visual acuity, and cataract grade were evaluated for 6 months after LSV as well as the correlation between myopic shift and cataract change at 6 months after LSV. RESULTS: Twenty-eight eyes were included in this study. The cataract status worsened by 1.07 levels, myopia progressed by 3.13 diopters (p < 0.001), and uncorrected visual acuity (log MAR) decreased from 0.73 to 0.98 (p = 0.022) at 6 months after LSV. Additional cataract surgery was performed in 22 eyes (78.6%) at 13.6 months on average during the follow-up period (average 16.9 months). In 6 eyes (21.4%) having myopic change below 1.0 diopters, crystalline lens was preserved for 36 months after vitrectomy. Conversely, 22 eyes (78.6%) with myopic change over 1.5 diopters required cataract surgery. Therefore, myopic change over 1.5 diopters could be a major postoperative change predicting the necessity for cataract surgery (p < 0.001). CONCLUSIONS: LSV for ERM caused a significant myopic shift and cataract changes in patients in their 5th and 6th decade of life and additional cataract surgery was required in 78.6% of patients within 3 years after vitrectomy. The myopic shift over 1.5 diopters at 6 months after vitrectomy could be a major postoperative change predicting the necessity for cataract surgery.

Long-term Results of Lens-sparing Vitrectomy for Progressive Posterior-type Stage 4A Retinopathy of Prematurity

PURPOSE: To assess the long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) in infants with progressive posterior-type tractional retinal detachment (TRD) associated with stage 4A retinopathy of prematurity (ROP). METHODS: In a retrospective case series, the medical records of consecutive patients who presented with progressive posterior-type stage 4A ROP and underwent LSV between 1999 and 2007 were reviewed. Retinal attachment status, visual acuity, and development of postoperative complications were assessed. RESULTS: Eleven eyes of 9 patients were included. The mean follow-up period was 4.6 years. In 8 eyes (73%), plus disease was present at the time of LSV. In 3 eyes (27%), 2 (66%) without plus disease and 1 (13%) with plus disease, the retina remained reattached in the end, while 8 eyes (73%) had TRD on final examination. Two eyes with reattached retinas showed favorable visual acuity. In those eyes with detached retinas, 5 (68%) showed no light perception. When surgery for ROP was unsuccessful, development of cataract, corneal opacity, or glaucoma was common. CONCLUSIONS: The long-term anatomic success rate of LSV for progressive posterior-type stage 4A ROP was low, especially in the presence of plus disease at the time of LSV. Anatomical reattachment is very important for preventing complications and gaining better visual outcomes.

Anatomic outcomes of scleral buckling or lens-sparing vitrectomy for stage 4 retinopathy of prematurity / 中华眼底病杂志

Objective To evaluate the anatomic outcome after lens-sparing vitrectomy (LSV) or scleral buckle (SB) for stage 4 retinopathy of prematurity (ROP).Methods The clinical data of 39 infants (50 eyes) with 4a (20 eyes) or 4b (30 eyes) were retrospectively analyzed.The age ranged from two to 18 months,with a mean of (6.0±3.4) months.The gestational age ranged from 26 to 33 weeks,with a mean of (30.0±1.6) weeks.The birth weight ranged from 800 to 1900 g,with a mean of (1404.5±237.6) g.Nineteen eyes underwent SB and 31 eyes underwent LSV.Follow-up ranged from 6 to 84 months,with a mean of (26.0±21.7) months.The anatomical and refractive results were reviewed at the final follow-up.Results The anatomic success of SB was 100.0％ (19 of 19 eyes) and that of LSV was 87.1％ (27 of 31eyes).Among the patients in whom treatment failed,4 were in the LSV group (4/31,12.9％).The buckles of 5 eyes (5/19,26.3％) were removed.At the end of the follow-up,the mean myopic refraction was (-4.46±2.49) diopters (ranging from -1.25 to 11.00 diopters) in the LSV group,and ( -3.21±1.96) diopters (ranging from -1.25 to 9.25 diopters) in the SB group.There was no significant difference between two groups (F=2.76,P=0.103).Conclusion The anatomic outcome after LSV or SB for stage 4 ROP was excellent.

Long-Term Results of Lens-Sparing Vitrectomy for Stages 4B and 5 Retinopathy of Prematurity

PURPOSE: To assess long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) for treatment of tractional retinal detachments (TRDs) associated with stages 4B and 5 retinopathy of prematurity (ROP). METHODS: We performed a retrospective review of medical records and data analyses of consecutive patients who presented with stages 4B and 5 ROP and underwent LSV from 1999 to 2007. Retinal reattachment status, visual acuity and postoperative complications were evaluated. RESULTS: Twenty-one eyes of 20 patients, including 13 eyes with stage 4B ROP and 8 eyes with stage 5 ROP, were examined. The mean follow-up period was 5.6 years. In 9 (43%) out of 21 eyes, retinas were eventually reattached. The anatomic success rates were 62% in stage 4B and 13% in stage 5 ROP. In eyes with reattached retinas, visual acuity better than form vision was shown in 7 eyes (78%), whereas no light perception was present in 10 eyes (83%) among eyes with TRD on final examination. Postoperative intraocular hemorrhage occurred in nine eyes (43%). Long-term complications of cataract, corneal opacity, glaucoma and strabismus developed in 4 (19%), 6 (29%), 7 (33%) and 8 (38%) eyes, respectively, and were more common in eyes with TRD. CONCLUSIONS: After following-up for a mean of 5.6 years, the anatomical success rate of LSV was encouraging for the correction of TRD associated with stage 4B ROP but not for stage 5 ROP. Retinal reattachment is important for obtaining better visual outcomes and preventing the development of late complications.

Functional and anatomical outcomes after primary lens-sparing pars plana vitrectomy for Stage 4 retinopathy of prematurity.

Background: While lens-sacrificing vitrectomy is the standard approach to manage Stage 5 retinopathy of prematurity (ROP), scleral buckling has been used to manage some cases of Stage 4. Lens-sparing vitrectomy was popularized by Maguire and Trese in selected cases of Stage 4 disease. Purpose: To assess the functional and visual outcomes after primary lens-sparing pars plana vitrectomy for Stage 4 ROP. Materials and Methods: In a retrospective, interventional, consecutive case series, the records of 39 eyes of 31 patients presenting with Stage 4 retinal detachment secondary to ROP who underwent primary two or three-port lens-sparing vitrectomy from January 2000 to October 2006 were evaluated. The outcomes studied at the final follow-up visit were the retinal status, lens and medial clarity and visual acuity. Favorable anatomical outcome was defined as the retinal reattachment of the posterior pole at two months after the surgery; and favorable functional outcome was defined as a central, steady and maintained fixation, with the child following light. Results: At mean follow-up of 15 months, 74% of the eyes had a favorable anatomical outcome with single procedure. The visual status was favorable in 63%. The lens remained clear in all the eyes at the last follow-up, and the media clarity was maintained in 87%. Intraoperative complications included vitreous hemorrhage, pre-retinal hemorrhage and retinal break formation. Conclusions: Lens-sparing vitrectomy helps to achieve a favorable anatomical and functional outcome in selected cases of Stage 4 ROP.

Lens-sparing Vitrectomy for Stage 4 and Stage 5 Retinopathy of Prematurity

PURPOSE: To describe the results of lens-sparing vitrectomy for the correction of retinal detachment associated with retinopathy of prematurity (ROP) and its associated complications. METHODS: Seventeen patients who underwent a lens-sparing vitrectomy for stage 4 and stage 5 ROP with plus disease at Seoul National University Children's Hospital between 1999 and 2003 were enrolled in this study. The patients who had bilateral retinal detachment of ROP underwent a lens-sparing vitrectomy in one eye and a scleral buckling surgery or lensectomy-vitrectomy in the other eye. The patients who had a retinal detachment in one eye and a regressed ROP in the other eye underwent unilateral lens-sparing vitrectomies. A review of their preoperative clinical findings (including the status of retinal detachment and plus disease), post-operative results, and any complications encountered was performed. RESULTS: In 17 patients, the postoperative success rate of lens-sparing vitrectomy was 58.8%. However, lens-sparing vitrectomy as a treatment for stage 5 ROP (25.0%) produced more negative post-operative results than it did when used to treat either those for stage 4a (75,0%) or 4b (66.7%) ROP. Among the 10 eyes in which the retina was attached, form vision was shown in six eyes, light could be followed by three eyes, and no light perception was present in one eye. Intra- and post-operative complications included retinal break formation, cataracts, vitreous hemorrhages, and glaucoma in patients with stages 4b and stage 5 ROP. CONCLUSIONS: Lens-sparing vitrectomy resulted in encouraging surgical outcomes in the correction of retinal detachment of ROP, especially in stage 4 patients. Therefore, a lens-sparing vitrectomy for stage 4 ROP patient may be beneficial, although it is still associated with some intra- and post-operative complications.
