Atypical bilateral presentation in idiopathic macular telangiectasia type 1

Idiopathic macular telangiectasia type 1 (MacTel 1) almost always occurs unilaterally. In this article, we report the case of a 73-year-old man with no significant history diagnosed with MacTel 1 but with atypical bilateral presentation, something very rare in this disease. The usefulness of multimodal imaging studies, including optical coherence tomography angiography (OCTA), is highlighted to differentiate it from macular telangectasia type 2 (MacTel 2). The patient's condition was characterized by cystoid macular edema (CME) with discreet results with treatment with a dexamethasone implant. However, aflibercept therapy showed favorable results, but with recurrences when extending the doses.
