Purpose Type 2 Macular Telangiectasia is a progressive disease starting in the fifth to seventh decade and characterized by a progressive damage of the neurosensory retina.. The purpose of this study is to compare the images obtained using two non‐invasive techniques, High‐Resolution Optical Coherence Tomography (HR‐OCT) and Adaptive Optics (AO), in Type 2 Macular Telangiectasia. Methods Nine eyes of 5 patients affected by Type 2 Macular Telangiectasia underwent examination including visual acuity measurement with ETDRS (Early Treatment of Diabetic Retinopathy Study) chart, color photographs, monochromatic photographs, Spectral‐Domain Optical Coherence Tomography with Heidelberg Spectralis™ OCT and Adaptive Optics assessment with Imagine Eyes™ System. The neurosensory retina and the photoreceptor layer were analyzed using both HR‐OCT and AO imaging. Results The disruptions of the photoreceptor layer on HR‐OCT correspond to a cellular loss on Adaptive Optics Imaging. On the other hand, Adaptive optics Imaging allows the measurement of cellular density in areas which have a normal aspect on HR‐OCT. Conclusion The diagnosis of Macular Telangiecctasia is based on biomicroscopy and fluorescein angiography. Adaptive Optics Imaging is helpful to analyze the retinal damages, especially the cone abnormalities. This technique will certainly allow a better understanding of this rare disease.
