Abstract

Purpose:: To compare C57Bl/6 mouse retinal thickness measured on histological sections and in vivo non-invasively using Optical Coherence Tomography (OCT).

Methods:: The retinas of 5 anesthetized C57Bl/6 mice were imaged with a custom-made non-contact slit-lamp based OCT system designed for the mouse eye. Cross-sectional images of the retina were acquired at 3 weeks and at 4 weeks of age along lines located 2 to 3 optic disc diameters away from the optic disc. The position of the scan was controlled using a simultaneous fundus image. Retinal thickness was measured from the retinal pigment epithelium-photoreceptor layer interface to the vitreo-retinal interface on randomly selected A-lines within the region of interest. After the second imaging session, the mice were euthanized and the eyes were enucleated, fixed in 10% formalin, embedded in paraffin and cut into 8 microns thick sections. Histological retinal thickness was measured on sections corresponding to the location of the OCT scan. Retinal thickness measured using histology and OCT was compared.

Results:: The average total retinal thickness measured from the OCT images was 178±4 microns. The average retinal thickness measured from the histological sections was 213±17 microns. The OCT thickness was found to be within the range of previously published values obtained by OCT imaging or frozen sections (Horio et al 2001, Schmucker and Schaeffel 2004,).

Conclusions:: The thickness obtained from histological sections was found to be significantly (19% on average) larger and more variable than the thickness obtained from OCT scans. This difference may stem from the difficulty in controlling the obliquity of the histological sections.Support: This work was supported in part by the generosity of the Wollowick Foundation; NIH grant R03 EY016322; NIH center grant P30-EY014801; Research to Prevent Blindness; The Florida Lions Eye Bank; The Henri and Flore Lesieur Foundation, West Palm Beach, FL.
