Abstract Purpose To describe clinical presentation, morphological features and surgical outcomes of macular hole (MH) secondary to retinal vein occlusion (RVO). Method This prospective interventional study evaluated eight eyes with atypical MH (secondary to RVO) and data regarding medical management, pars plana vitrectomy, postoperative anatomical hole closure, visual acuity improvement, morphological features of hole were noted till the last follow-up. Results Eight eyes with full-thickness MH in an RVO eye were followed-up for a minimum period of 3 months postoperatively. Five subjects had a RVO episode which occurred more than 6 months before the onset of the recent symptoms (Group 1; 4 branch RVO and 1 central RVO), and 3 subjects had a recent onset branch RVO within 6 months (Group 2). All FTMH cases except one showed closure at the last follow-up. Visual acuity of all eyes improved from 0.91 ± 0.57 logMAR to 0.5 ± 0.3 logMAR

(p = 0.093). At baseline, visual acuities of the two groups had no significant difference. Postoperatively, group 1 holes had better visual prognosis, than Group 2 holes, further substantiated by persistence of subretinal fluid in Group 2 eyes till last follow-up. Minimum hole diameter was higher in the recent RVO group, although anatomical closure was obtained in all of these eyes. Most holes had favorable morphological hole features like raised configuration with rounded edges. Conclusion In the presence of favorable morphological features, secondary macular holes associated with retinal vein occlusion may show optimal outcomes after surgery. It is not clear whether acutely created holes in recent onset RVO should be operated early. Older holes may have better prognosis.

Introduction Macular hole (MH) is a rare but reported complication of retinal vein occlusion (RVO). Most of these MH are secondary to chronic macular edema (ME). Alternate and additional mechanisms are expected in the formation of these MH unlike the classical anteroposterior vitreous traction (A–P traction) and tangential
