“…23 The other study by Suwal and colleagues involving 12 eyes undergoing surgery mentioned a follow-up period of 6 months, which is again inadequate to properly assess the final outcome. 24 In our series, 45.2% of eyes developed redetachment, with 50% of them showing redetachment within 6 months after the first vitrectomy surgery. Several of these cases required SOIs to be repeated for redetachments.…”

Purpose: Choroidal coloboma (CC) eyes are associated with a high risk of retinal detachment (RD), which are challenging to repair. Methods: We retrospectively evaluated medical records of 30 patients with CC associated with RD who underwent pars plana vitrectomy at our tertiary care center. Data recorded were age, CC and RD morphology, breaks, resurgeries performed, and final outcome. Results: Patients’ ages ranged from 2 to 49 years. CC was present in 53 of 60 eyes (88%), with 41 of 60 eyes (68.3%) associated with iris coloboma. RD was present in 36 of 53 CC eyes (67.9%), with 10 of 53 (18.9%) having bilateral RD. Thirty-one eyes with RD underwent 23-gauge pars plana vitrectomy. Colobomatous region breaks were detected in 5 of 31 eyes (16.1%), peripheral breaks only in 12 of 31 (38.7%), and both types in 3 of 31 eyes (9.7%). Silicone oil endotamponade was used in 29 of 31 eyes (93.5%) and perfluoropropane (C3F8) in 2 of 31 eyes (6.45%). Median postoperative follow-up duration was 31.5 months. Fourteen of 31 eyes (45.2%) developed redetachment requiring resurgery, with 50% developing within 6 months. Eighteen of 31 eyes (58.1%) maintained retinal attachment at last follow-up without endotamponade, whereas the rest were oil filled. Final visual outcome between macula-involved and macula-spared CC eyes was not significantly different; however, best visual acuity achieved any time during follow-up was significantly better in macula-spared eyes. Conclusions: RD surgery in CC eyes has a risk of frequent redetachments and subnormal gain of vision over the long term, especially in colobomas involving the macula. Endolaser in 360° peripheries in addition to barrage of the margin of the coloboma may be considered to help maintain the attached retina.

“…The anatomical success rate of MIVS in coloboma RD in our series of patients was 90.5%, which was comparable to the success rate of PPV and oil tamponade reported in the literature. [ 8 10 11 12 12 ] However, it remains difficult to accurately compare the anatomical success rates between two studies due to the heterogeneity of the cases and differences in the definition of anatomical success. A review of the literature pertaining to the various studies on the surgical outcomes of coloboma retinal detachments is described in Table 4 .…”

Purpose: To analyze the anatomical and visual outcomes of microincision vitrectomy surgery (MIVS) with silicone oil tamponade in eyes having coloboma-related retinal detachment (RD) and evaluate the risk factors for recurrence of RD. Methods: This was a retrospective, multicentric analysis of eyes having coloboma RD undergoing MIVS with silicone oil tamponade between March 2010 and July 2018. Results: We evaluated 148 eyes of 144 patients. The mean age of presentation was 17.4 ± 9.8 years (range: 2–65 years) and the mean follow-up duration was 13.1 ± 13.8 months (range: 3–84 months). The single operation success rate was 88.5% (131 eyes), with an overall successful outcome achieved in 90.5% (134 eyes). Recurrence of RD occurred in 17 eyes (11.5%) over a mean duration of 2.59 ± 3 months. The risk of recurrence was found to be higher in eyes where relaxing retinectomy (RR) was performed (odds ratio [OR]: 3.22; P = 0.05). A statistically significant improvement in vision was noted in the majority of cases from logMAR 1.85 ± 0.34 preoperatively to logMAR 1.33 ± 0.6 post-surgery ( P = 0.002). Conclusion: MIVS with silicone oil tamponade provided an anatomical success rate of 90.5% in eyes with coloboma RD with a significant improvement in visual acuity. Eyes in which RR was performed were susceptible to higher rates of re-detachment.

“…Incidence of RRD is 2.4 -42%, this can occur in the abnormally dysplastic retina colobomatous retina or extra colobomatous area. 4 Patients presented with coloboma of posterior segment were treated with barrage laser to the edges of the coloboma as prophylactic treatment to prevent RRD and patients with RRD underwent surgical management, pars plana vitrectomy with silicone oil tamponade. Surgical results in our study were good in 2 cases, in one case anatomical outcome was good but visual outcome was not favourable probably due to secondary glaucoma.…”

BACKGROUND Paediatric retinal diseases are very different from adults, presentation is unique compared to adults, various hereditary and acquired causes of retinal disorders are discussed in our study. Though we have significantly advanced techniques to diagnose, still management of these cases is really challenging to vitreo retinal surgeons. We wanted to study various causes of retinal diseases seen in the paediatric population at a tertiary eye hospital in Telangana state. METHODS All paediatric cases presented to vitreo-retinal department of Sarojini Devi Eye Hospital were studied in detail from electronic medical records to know the various retinal diseases in children. Retrospective study was done. Patients of different age groups who presented from paediatric ophthalmology dept. for indirect ophthalmoscopy were examined in detail. Data of patients who presented to vitreoretinal dept. during June 2016 to June 2018 were collected from the records. All patients underwent detailed ocular and systemic examination, and management was done based on the clinical presentation. 120 patients were referred during the two-year period from paediatric ophthalmology department to retina dept.; age range was between 2 to 15 years; mean age of presentation was 9 years, most of the patients were male. RESULTS All 120 patients were examined in detail and treated based on the clinical presentation, many conditions were congenital; acquired causes were also noted. Results were not favourable due to delayed presentation. CONCLUSIONS Early detection of low vision in children helps to prevent blindness. Regular and frequent screening programmes at schools also help in preventing blindness in children.
