PURPOSE: To report the long-term visual outcomes of surgical removal of extensive peripapillary choroidal neovascularization associated with presumed ocular histoplasmosis syndrome (POHS). DESIGN: Long-term retrospective review. Follow-up ranged from 14 to 139 months (mean, 68). PARTICIPANTS: Forty consecutive eyes (in 35 patients) undergoing surgical removal of extensive peripapillary choroidal neovascularization associated with POHS at the Barnes Retina Institute between May 1992 and December 2003 were included in this review. Patient age ranged from 5 to 73 years (median, 34.5). All eyes were ineligible for laser treatment by Macular Photocoagulation Study criteria. INTERVENTION: Pars plana vitrectomy and surgical removal of choroidal neovascularization were performed. MAIN OUTCOME MEASURES: Determination of Snellen best-corrected visual acuity (BCVA), funduscopic examination, and intravenous fluorescein angiography were done before surgery and at regular intervals after surgery. RESULTS: In the 23 eyes with subfoveal extension of peripapillary choroidal neovascularization, preoperative BCVA ranged from 20/25 to counting fingers (CF) at 2 feet (median, 20/200). Final postoperative BCVA ranged from 20/15 to CF at 2 feet (median, 20/50). Of 23 eyes, 18 achieved stable or improved BCVA from the preoperative to the final postoperative examination; only 5 eyes had > or =2 lines of decreased BCVA. Overall, 11 of 23 eyes achieved > or =20/40 BCVA at the final postoperative examination. In the 17 eyes in which choroidal neovascularization remained extrafoveal, preoperative BCVA ranged from 20/20 to 20/400 (median, 20/60). Final BCVA ranged from 20/20 to 20/200 (median, 20/20). Of 17 eyes, 15 achieved stable or improved BCVA from preoperative to final postoperative examination; only 2 eyes had > or =2 lines of decreased BCVA. Overall, 14 of 17 eyes achieved > or =20/40 BCVA at the final postoperative examination. CONCLUSIONS: The data from this small retrospective study suggest that surgical removal may provide visual benefit in selected cases of extensive peripapillary choroidal neovascularization associated with POHS. Surgical removal of extensive peripapillary choroidal neovascularization does appear preferable to photoablation. Given the likelihood of multiple treatments with photodynamic therapy or anti-vascular endothelial growth factor therapies, surgical removal provides a potentially efficacious treatment with low recurrence rates and good visual results.
