Mustafa A. Ali, Shakir M. Mirhish


The current study  includes eye balls of Iraqi geese (anser anser). The anatomical characteristics and histological eye structure. The eye ball shape was nearly spherical. The general mean size of the geese's right and left eye was 2.3 ± 0.07 ml.

 The ciliary body was the anterior part of the choroid and it joined anteriorly with the iris. The retina was the deepest layer of the eyeball jacket. The retina had two parts, one sensory and the other meaningless.

The sensory part of the retina of the ciliary body began to cover the ciliary body and the iris. The sensory part of the retina consists of ten layers: (1) the pigmented epithelium of the retina (2) of the rods and cones (3) the outer specific membrane (4) the outer nuclear layer (5) the outer layer (6) Internal plexus (8) Layer node cell (9) Fiber optic layer (10) Internal boundary membrane. . The total values of retinal thickness is 304.68±0.95 µm.
