Long-Term Follow-Up of an Atypical Case of Idiopathic Macular Telangiectasia

The authors present a 6-year follow-up of an atypical case of idiopathic macular telangiectasia (IMT) type 1 in a 67-year-old man treated with intravitreal injections of anti-vascular endothelial growth factor (VEGF) and subthreshold micropulse yellow laser. In this case, the authors detected a bilateral idiopathic macular telangiectasia. The right eye was characterized by a severe cystoid macular edema, whereas in the left eye, small cysts with small pseudovitelliform macular lesion were detected. Anti-VEGF intravitreal injections were performed in absence of functional or anatomical results in the right eye. After a single subthreshold micropulse yellow laser treatment, the authors reported an important reduction of intraretinal cysts with the restoration of the foveal depression in the right eye. During the follow-up, the left eye remained stable. To the authors' knowledge, this is the first reported case of macular telangiectasia with a such long optical coherence tomography follow-up treated using micropulse yellow laser. The follow-up examination is fundamental to disentangle atypical cases, especially in these conditions in which there is an overlap of different clinical elements.
