Different treatment modalities for choroidal neovascularization in two eyes of one patient with bilateral type 2A parafoveal telangiectasia

A 60-year-old diabetic man presented with a history of decrease in vision in both eyes since 2 weeks. At presentation, best corrected visual acuity (BCVA) in the right eye (RE) was 20/30 and that in the left eye (LE) was 20/80. The right fundus revealed a grayish reflex, yellowish crystalline deposits and retinal pigment epithelial hyperplasia at the macula. The left fundus showed subretinal fluid and temporal subretinal hemorrhage near a grayish reflex at the macula. A diagnosis in both eyes of idiopathic macular telangiectasia (IMT) type 2A with RE stage 4 and LE stage 5, choroidal neovascularization (CNVM) was made. The patient was treated with photodynamic therapy (PDT) in LE. The visual acuity improved to 20/40 over the next 6 months. At a 4-year follow-up, he developed decreased vision in RE diagnosed as IMT with CNV and was treated with intravitreal ranibizumab. At 6-month follow-up post injection, the vision was 20/40p.
