Characteristics and management of macular hole developing after rhegmatogenous retinal detachment repair.

Purpose: To report characteristics of patients developing full-thickness macular hole (MH) after rhegmatogenous retinal detachment (RRD) repair surgery. We also compared patients developing MH with and without accompanying RRD recurrence regarding anatomical and visual outcomes of MH repair.

Design: Retrospective study.

Methods: Medical records of patients who developed MH after RRD repair between January 2002 and January 2018 were reviewed.

Results: We performed 1661 primary RRD operations during the study period and 14 of these developed MH, an incidence of 0.8%. Nine patients had their primary RRD repair surgery in another clinic and were referred to our clinic after development of MH. In total 23 patients with MH secondary to RRD repair were included in the study. The type of RRD repair surgery was scleral buckling only in 4 patients (17%), pars plana vitrectomy (PPV) only in 14 patients (61%), and sequential scleral buckling and PPV in 5 patients (22%). Nineteen patients (83%) had macula-off RRD. In 12 patients (52%), MH developed within 3 months after RRD repair. Surgery for MH repair was performed in 18 patients. Postoperative best corrected visual acuity (BCVA) was better than preoperative BCVA in the group with RRD recurrence as well as in the group without RRD recurrence (both P < 0.05). There wasn't a significant difference between these groups regarding postoperative visual gain and anatomical success (P > 0.05).

Conclusion: MH can develop after various surgical methods of RRD repair. Anatomic closure and visual acuity gain can be achieved even if patients have accompanying RRD recurrence.
