| Abstract | ||||
| The morphology of the goat aqueous outflow system and the iridocorneal anglewas studied in fifteen normal eyes from adult apparently healthy goats using light and scanning electron microscopy. The iridocorneal angle of the goat includes the pectinate ligament, the ciliary cleft, the trabecular meshwork (uveal and corneoscleral) and the angular aqueous plexus. The iridocorneal angle of the eye of goat was large; its length measured 1.3- 1.7 mm and its width measured 1.0- 1.2 mm anteriorly and 0.20-0.27 mm posteriorly. The pectinate liga- mentwas a strong, band-like structure extending from the iridal base to the limbic zone. Its length varied from 500-700 μm and its thickness was 120-150 μm. There were spac- es and pores between its strands. The ciliary cleft contained a large amount of trabecular tissue that could be divided into two distinct parts: the uveal meshwork and the corneoscleral meshwork. The angular aqueous plexus consisted of three to four endothelial-lined vessels or veins, located between the corneoscleral meshwork and the sclera. The results of this study revealed that the incidence of glaucoma in goat might be very rare. | ||||
