3. Pigment dispersion
Pigment dispersion is a cardinal characteristic. It refers back to the launch of pigment granules from the iris, the coloured a part of the attention. Within the context of this situation, this launch is pathological and extreme. The launched pigment, sometimes melanin, floats freely throughout the anterior chamber, the fluid-filled area between the cornea and the iris. The buildup of this pigment can then hinder the traditional drainage pathways, resulting in elevated intraocular stress. The dispersion itself is a direct consequence of the power inflammatory course of affecting the uveal tissues, particularly the iris. The pigment granules are liberated because the iris undergoes structural modifications attributable to irritation.
Take into account, as an example, a Golden Retriever recognized with the illness. Throughout a slit-lamp examination, the veterinary ophthalmologist will observe the presence of pigment dusting on the corneal endothelium (the inside layer of the cornea), on the lens floor, and throughout the trabecular meshwork, the attention’s drainage system.
