Abstract

PurposeTo study the anatomical and visual outcomes of surgery for retinal detachment (RD) in patients with choroidal coloboma.MethodsForty-six eyes of 46 patients underwent surgery for RD with choroidal coloboma. Patients were divided into three groups, according to the extent of choroidal coloboma: Coloboma not involving the disc and macula (Group A), coloboma involving the disc (Group B), and coloboma involving the disc and macula (Group C). Thirty-eight eyes underwent pars plana vitrectomy with silicone oil (SO) (Group 1) and eight eyes underwent scleral buckling surgery (Group 2). SO removal was carried out in 18 eyes at final follow up.ResultsAfter a mean follow-up of 16.2 months, 40 eyes (86.9%) had an attached retina and the best corrected visual acuity (VA) improved from a preoperative median of 20/800 to 20/250 (p = 0.001). Thirty-four eyes (74%) recovered ≥20/400 VA. The final median VA in Group A (20/200) was better than in Group B (20/800) and Group C (light perception and hand movement) which was statistically significant (p = 0.01). Redetachment occurred in 10 eyes (21.8%), of which 7 eyes (18.91%) belonged to Group 1 and 3 eyes (37.5%) belonged to Group 2, and all of these eyes underwent resurgery. Of these 10 eyes, 9 had an attached retina at final follow up.ConclusionPostoperative visual recovery in RD with choroidal coloboma is dependent upon the involvement of the disc and macula with the colobomatous area. Resurgery following redetachment improves the final anatomical outcomes.
