PURPOSE: To present the 2-year outcomes of surgical removal of non-age-related macular degeneration (AMD)-related choroidal neovascular membranes and to evaluate any association between visual outcome and baseline clinical factors. METHODS: Retrospective consecutive case series. All patients who had surgery for non-AMD-related choroidal neovascularisation (CNV) between November 1997 and March 2003 under the care of a single surgeon (WA) were included in the study. Baseline data including patient age, duration of subfoveal CNV, preoperative visual acuity (VA), lesion size, lesion components and aetiology were collected. The primary outcome was VA change with secondary outcomes retinal detachment, operative peripheral retinal break formation, CNV recurrence and cataract. RESULTS: A total of 52 eyes were included in the study. The aetiology of CNV was: punctate inner choridopathy 21 (40%); idiopathic 8 (15%); pathologic myopia 6 (12%); ocular histoplasmosis syndrome 1 (2%); and other 16 (31%). The mean age of patients was 41(range 14-72) years. 24-month follow-up was available for 41 (80%) eyes. The mean logMAR equivalent baseline acuity was 1.1 and mean lesion size 1.2 disc areas. An improvement in VA >1 Snellen line was noted in 26 (63%) eyes, whereas 10 (24%) eyes remained the same (within 1 line) and 5 (12%) lost >1 line of acuity. Improvement in VA was associated with worse baseline VA (84% for eyes with VA <or=6/36 vs 31% for those with VA>6/36, p=0.001). No evidence of association between 2-year visual outcome and any other baseline factor under study was observed. Peripheral retinal breaks were noted in 5 (10%) eyes at the time of surgery, and 3 (5.8%) eyes developed postoperative retinal detachments. Persistent/recurrent CNV was noted in 17 (33%) eyes. The median time to presentation of CNV in these eyes was 27 (range 2-172) weeks. Five eyes underwent cataract surgery during the follow-up period. The mean age of these patients was significantly higher than the mean age of those who did not require cataract surgery (57 vs 37 years, p=0.014). CONCLUSIONS: Surgical excision of non-AMD-related CNV resulted in improvement of VA in the majority of eyes. Worse presenting acuity was associated with better visual improvements.
