Purpose: To re-evaluate effects and visual prognosis after surgical removal of choroidal neovascularization (CNV) in age-related macular degeneration(AMD). Methods: Fifty seven eyes of 56 patients underwent surgical removal CNV in AMD by a single surgeon. Forty eyes had subfoveal CNV and 17 eyes had juxtafoveal CNV. Postoperative visual prognosis was analyzed according to various preoperative factors, such as type, size and location of CNV, OCT findings, age of the patients. Results:Twenty seven eyes (47%) obtained visual improvement of two lines or more. Visual acuity of 22 eyes (39%) remained within two lines. Eight eyes (14%) showed visual deterioration. Factors associated with the final visual acuity better than 20/100 were smaller CNV (less than 1 disc diameter) and younger age (younger than 70 years). Eyes with juxtafoveal CNV demonstrated better visual prognosis compared to those with subfoveal CNV. Surgical complications included retinal breaks (4%), retinal detachment (5%) and recurrence of CNV (4%). Conclusions: These results appear to be comparable to or better than the results of other treatments. Simple surgical removal of CNV is a safe and effective modality for the treatment of CNV in AMD.
