Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.

Inclusion Criteria:

1. participants diagnosed with ERM or FTMH and co-existing macular drusen;
2. undergone pars plana vitrectomy with ILM and epiretinale membrane peeling;
3. SD-OCT at the initial visit and at last follow up visit with image quality score >30;
4. no evidence of CNV on initial fluorescein angiography (FA).

Exclusion Criteria:

1. history of other macular disease, severe non-proliferative or proliferative diabetic retinopathy, other retinal vascular diseases, glaucoma, myopic retinopathy, or other diseases interfering with OCT images in any one of the eyes;
2. active CNV or history of CNV

mostly elderly people, mean age 66 years, both males and females
