FULL-THICKNESS MACULAR HOLE WITH PERSISTENT BROAD VITREOMACULAR ATTACHMENT: Clinical Characteristics and Surgical Outcomes.

PURPOSE: To describe the characteristics and surgical outcomes of full-thickness macular holes (FTMHs) with persistent broad vitreomacular attachment.

METHODS

This was a retrospective, observational case series. Consecutive patients undergoing pars plana vitrectomy for FTMHs with persistent broad vitreomacular attachment (study group) were reviewed. Clinical charts, optical coherence tomography (OCT) features of macular holes, and surgical outcomes were reviewed and compared with those with typical FTMH with focal vitreomacular traction (control group).

RESULTS

A total of 15 eyes of 14 consecutive patients (eight males and six females with a mean age of 60.6 years) were included in the study group. OCT showed a zone of at least 1,500 µm all around the circumference of the fovea where the vitreous was attached. On OCT, epiretinal membrane and epiretinal proliferation were observed in 73% and 87% of cases, respectively. Compared with the control group, the study group was younger (P = 0.027) and had better preoperative visual acuity (P = 0.007). All FTMHs closed after one surgery in both groups, and the postoperative visual acuity of the study group was better than that of the control group (P = 0.002).

CONCLUSION

Full-thickness macular holes may have developed under the condition that the vitreous cortex was broadly attached around the hole. These FTMHs were associated with younger age, better baseline visual acuity, and a higher incidence of epiretinal membranes and epiretinal proliferations compared with macular hole with focal vitreomacular traction. The surgical outcome was favorable, but the pathogenesis of FTMH development remains unclear.
