Case 2: Cirrus™ HD-OCT Horizontal 5-Line Raster Scan Images OS An OCT section through the lesion reveals the retinal layers surrounding the lesion are intact and normal, but as they progress towards the lesion several of the outer retinal layers "collapse". Multiple retinal layers are absent throughout

Case 2: Cirrus™ HD-OCT Horizontal Single Line Raster Scan Images OD A horizontal OCT section through the macula reveals an intact PIL which correlates to the near normal VA. The external limiting membrane (ELM) is also well visualized.

Case 2: Zeiss FF450plus Color Fundus and Autofluorescence Camera* Comparison of Left Eye Note the hypoautofluorescent zone occupies nearly the entire area of the largest retinal lesion. * VISUPAC 481 ZK5 and Pike 145

Case 2: Zeiss FF450plus Color Fundus and Autofluorescence Camera* Comparison of Left Eye The hypoautofluorescent zones corresponded to the retinal lesions. These are due to the low levels of lipofuscin secondary to the absent RPE cells. * VISUPAC 481 ZK5 and Pike 145
