PURPOSE: To quantify impressions of mitochondrial translocation in degenerating cones and to determine the nature of accumulated material in the subretinal space with apparent inner segment (IS)-like features by examining cone IS ultrastructure. METHODS: Human donor eyes with advanced age-related macular degeneration (AMD) were screened for outer retinal tubulation (ORT) in macula-wide, high-resolution digital sections. Degenerating cones inside ORT (ORT cones) and outside ORT (non-ORT cones) from AMD eyes and unaffected cones in age-matched control eyes were imaged using transmission electron microscopy. The distances of mitochondria to the external limiting membrane (ELM), cone IS length, and cone IS width at …


Outer Retinal Tubulation In Advanced Age-Related Macular Degeneration: Optical Coherence Tomographic Findings Correspond To Histology, K. B. Schaal, K. B. Freund, K. M. Litts, Y. Zhang, J. D. Messinger, C. A. Curcio Jan 2015

Outer Retinal Tubulation In Advanced Age-Related Macular Degeneration: Optical Coherence Tomographic Findings Correspond To Histology, K. B. Schaal, K. B. Freund, K. M. Litts, Y. Zhang, J. D. Messinger, C. A. Curcio

PURPOSE: To compare optical coherence tomography (OCT) and histology of outer retinal tubulation (ORT) secondary to advanced age-related macular degeneration in patients and in postmortem specimens, with particular attention to the basis of the hyperreflective border of ORT. METHOD: A private referral practice (imaging) and an academic research laboratory (histology) collaborated on two retrospective case series. High-resolution OCT raster scans of 43 eyes (34 patients) manifesting ORT secondary to advanced age-related macular degeneration were compared to high-resolution histologic sections through the fovea and superior perifovea of donor eyes (13 atrophic age-related macular degeneration and 40 neovascular age-related macular degeneration) preserved
