What are the symptoms of feline retinitis? The causative factors of retinitis can be divided into exogenous and endogenous. Bacterial infection, foreign matter entering the eyes, and disease induction may cause the disease. So what do cats with retinitis have? What about symptoms?

The main clinical manifestations of this disease are central vision loss, central scotoma, and visual distortion. There were no inflammatory changes in the anterior segment and vitreous body. There are yellow-gray exudative lesions and hemorrhage in the macular area of ​​the fundus, which are round or oval in shape, with unclear boundaries, slightly raised, and are approximately 1/4 to 3/2 of the optic disc diameter. It is more common with 1PD or less. There are arc-shaped or ring-shaped hemorrhages at the edge of the lesions, and occasionally there are spot-like hemorrhages arranged in a radial pattern. There is a pigment disorder zone around the lesion. Many cases are complicated by discoid superficial retinal detachment, and some have hard lipid exudation around them. Most lesions are centered on the fovea and have a radius within 1 PD.

At the end of the disease, yellow-white scars form in the macular area. Fluorescent fundus angiography shows that in the early arterial or arterial phase, there are granular, lace-like and other new blood vessel networks in various forms at the exudation focus. The bleeding area blocks fluorescence, and there is a ventilated fluorescent area at the upper edge of the bleeding area. In the later stage, fluorescein leaks from the new blood vessels to form a strong fluorescence area.
