Outcome of optic disc capillary hemangioma following intravitreal ranibizumab injection: A case report

Optic disc capillary hemangiomas, a rare capillary hamartoma that often invades optic nerve fibers and disc plaque bundles, have been a therapeutic challenge for ophthalmologists in recent years due to their unique location. A woman in her early 50s presented with blurred vision in the right eye for 2 days. On ocular examination, her best-corrected visual acuity was 20/340 in the right eye. Wide-field fundus imaging revealed a red mass on the temporal side of the optic disc. Optical coherence tomography revealed macular edema. The diagnosis was optic disc capillary hemangioma. Subsequently, 0.5 mg ranibizumab was intravitreally injected into the right eye once monthly, for a total of two injections. The patient was re-examined at 15 days, 50 days, and 21 months after the first operation. The patient's postoperative best-corrected visual acuity improved to 20/60, and macular edema and exudation were reduced in the short term compared with those in the previous period; however, the tumor did not change significantly. The anti-vascular endothelial growth factor agent ranibizumab is effective in treating optic disc capillary hemangiomas.
