Multiple Choroidal Neovascularizations in Choroidal Osteoma Treated with Anti-VEGF Injections: A 6-Year Follow-Up Case Report.

PURPOSE: To report a case of multiple choroidal neovascularizations (CNVs) secondary to choroidal osteoma injected with a total of 13 anti-vascular endothelial growth factor (VEGF) drugs over a long-term follow up of 6-year period.

METHODS: Case report.

RESULTS: A 29-year-old female presented with a peripapillary choroidal osteoma in her left eye with the best-corrected visual acuity (BCVA) of 20/25. After 2 years of follow-up, two foci of CNV (one was at the infra-nasal of the optic disc, and the other was near the sub-temporal vascular arch), and massive subretinal hemorrhage developed overlying the osteoma, causing decreased BCVA of 20/33. The patient was treated with four consecutive intravitreal injections of conbercept and the two CNVs regressed with BCVA recovered to 20/25. While 17 months later, the third CNV lesion locating at the fovea appeared and nine more injections of aflibercept were given during which repeated recurrence of it occurred. At last follow-up, 6 years from baseline, all the three CNV foci were controlled, with final BCVA of 20/33.

CONCLUSIONS: Multiple CNVs may appear simultaneously at different locations in one osteoma and prompt treatment with intravitreal anti-VEGF may be a good option to control the progression and recurrence of these CNVs. Long-term follow-up and multimodal imaging are vital in the management of CO-associated CNV.
