Relationship between Distribution of Tapetum Fibrosum and Retinal Pigment Epithelium in the Sheep Eye

open access: hybridJournal of Veterinary Medical Science, 2010
The tapetum lucidum is a light-reflective device improving visual sensitivity in mesopic vision. There have been few studies on tapetal distribution and its relationship with degree of pigmentation in the retinal pigment epithelium (RPE). In the present study, sheep's eyes were used for macroscopical observation of the tapetum, and then histological ...

The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians

open access: yesThe Anatomical Record, EarlyView., 2023
