ABSTRACT
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.
