Brief Summary

Macular hole in proliferative diabetic retinopathy with fibrovascular proliferation may have unique features. Internal limiting membrane peeling facilitates hole closure only in cases with shallow macular detachment. Final vision is associated with preoperative visual acuity and degree of macula elevation.

Phase 4Completed

Indications for surgery had been the severe complications of diabetic retinopathy and not the mere presence of macular hole alone.

Macular hole is found either preoperatively or during operation.

All cases are included in the study have attached retina postoperatively.

You may not qualify if:

Cases with recurrent rhegmatogenous detachment or post-operative dense cataract without lens extraction.
Follow-up duration of patients less than 3 months .
Incomplete medical records.
