Comparison of Cone Pathologic Changes in Idiopathic Macular Telangiectasia Types 1 and 2 Using Adaptive Optics Scanning Laser Ophthalmoscopy – Corrected Proof
Purpose: To compare pathologic changes in the photoreceptors of eyes with idiopathic macular telangiectasia types 1 and 2 using adaptive optics scanning laser ophthalmoscopy (AO-SLO).Design: Prospective cross-sectional study.Methods: Eleven eyes with idiopathic macular telangiectasia type 1, 14 eyes with type 2, and 10 normal eyes underwent a full ophthalmologic examination, spectral-domain optical coherence tomography (SD-OCT), and imaging with an original prototype AO-SLO system. All eyes with idiopathic macular telangiectasia were examined with fluorescein angiography (FA), confocal blue reflectance, and microperimetry.Results: Compared with normal eyes (29 017 ± 5507 cones/mm2), those with idiopathic macular telangiectasia type 1 had significantly lower cone density (Read more...)
