Light and electron microscopic structure of goat's retina [electronic resource].

Includes references.

The present study was conducting aiming to throw the light on the retinal structure on the level of both light and electron microscope. Eyeballs of 35 adult clinically healtby goats of both seIes were collected from DeDi- Suet abattoir. The eyeballs were clinically eumined before they were dissected. and fixed in 10% buffed neutral formalin and in Bouin'. solutiull for 24 hours. The specimens were then processed for light and transmission electron microscope:. The retina (pars _optica retinae) of the goats extends rostrally to cover the ciliary body as parsciliaris retinae and the iris as the pars iridis retinae. Pars optic'" retinae and pars iridis retinae·· form tbe light non sensitive parts of the retina, while the sensitive part except at tbe transition zone; the- ora serrata and the optic disc, appeared to be formed of ten layers, named from outward to inward as, retinal pigmented epithelium, rods and coneS layer (photoreceptor cell layer), external limiting membrane, outer noclear layer (cell bodies and nuclei of the photoreceptor cells), outer plexiform layer, inner nuclear layer (contained tbe horizontal, bipolar, Muller and amacrine cells), inner plexiform layer, ganglionic cell layer, nerve fiber cell layer (unmyelinatednene fibers) and internal limiting membrane.
