To describe Spectral-domain (SD) OCT findings of eyes with Type 2 Macular Telangiectasia.
Retrospective chart review of 6 patients (12 eyes) diagnosed with type 2 macular telangiectasia was performed. All patients underwent fluorescein angiography (FA), SD OCT (Heidelberg Spectralis) examination as well as an evaluation with the Time-domain (TD) OCT (Zeiss).
The average age of the patients was 68 years. All eyes had bilateral temporal FA staining of varying degree. TD OCT showed cystic changes in 4 eyes. SD OCT findings were: 1) Outer nuclear layer disruption (8 eyes), 2) Cystic changes (7 eyes) and, 3) Outer plexiform layer clumps or deposits (4 eyes). Both SD and TD OCT in 1 eye detected retinal neo-vascularization with sub-retinal fluid.
High-resolution SD OCT findings show that eyes with type 2 macular telangiectasia have varying degree of abnormality at the level of outer nuclear and outer plexiform layer previously not detectable by TD OCT. SD OCT imaging may be used to improve our understanding of different stages of macular telangiectasia.
