We report the case of a 52-year old man with no previous significant medical history presenting with progressive decrease in visual acuity (VA) of the right eye evolving over 10 years. Corrected visual acuity was 2/10 - P6 in the RE and 10/10 - P2 in the LE. The examination of the anterior segment was unremarkable. Fundus examination showed alteration of the pigment epithelium (APE) in the RE associated with osteoblast-like pigment migrations involving the macula and a wide area due to gravitational descent of the superior temporal arcade onto the lower temporal quadrant. The left eye had a similar appearance especially in the inter-papillo-macular region (A,B). Fluorescein angiography showed early hyperfluorescence areas in the PE depigmented areas associated with pigment migrations giving a comet tail appearance by gravity casting in both eyes (C,D). Optical coherence tomography (OCT) showed retrofoveolar epithelial detachment (PED) at the level of the RE (E). The patient received Diamox therapy with regular monitoring to manage possible leakage points. Patient 's evolution was marked by PED regression and VA improvement.

January 2025
Nethralayam Superspeciality Eye Care, Kolkata, India.
Purpose: To evaluate the efficacy of faricimab in real-world clinical settings in India for treating diabetic macular edema (DME) in treatment-naïve and recalcitrant eyes.
Patients And Methods: This retrospective study involved 39 eyes (16 treatment-naive and 23 recalcitrant) treated with intravitreal faricimab at four centers in India. Patients received three monthly loading doses followed by a pro-re-nata regimen, with outcomes measured for best-corrected visual acuity (BCVA), central macular thickness (CMT), intraretinal fluid (IRF), subretinal fluid (SRF), and hyperreflective foci (HRF).
