Effective Intravitreal Injections of Bevacizumab in a Case of Serous Macular Detachment from the Superior Border of the Posterior Staphyloma

PURPOSE We present an atypical case of submacular fluid leading to serous macular detachment. METHOD/PATIENT A 69-year-old man was evaluated for metamorphopsia in the left eye. RESULTS Best-corrected visual acuity was 20/25 in both eyes. He had undergone cataract surgeries in both eyes 12 years ago. The axial length was 25.93 mm (OD) and 24.12 mm (OS). Optical coherence tomography showed posterior staphylomas and subretinal fluid on the superior border of the staphylomas in both eyes; in the left eye, submacular fluid was noted extending up to the macula. Fundus fluorescein angiography revealed leakage from the superior border of the staphylomas in both eyes. The fluid persisted for 4 months. Four consecutive, monthly injections of bevacizumab (1.25 mg/0.05 mL) were administered in the left eye; subsequently, the subretinal fluid gradually dissipated from the macula and became localized at the superior border of the staphyloma. This localization persisted for 12 months. CONCLUSIONS We have detailed a case of submacular fluid that spread from the superior border of the posterior staphyloma in a patient with macular detachment, in whom intravitreal injections of bevacizumab were highly effective in eliminating the fluid.
