12/13/2023 0 Comments Detached retina in cats![]() The detached retinal part will not function properly and blurriness or a black spot in vision will appear. This is how the retina starts to progressively detach from the eye wall. My experience is this: if retinal detachment is detected while the retina is only partly peeled away, it will reattach once the blood pressure is controlled. Feline Progressive Retinal Atrophy (PRA-rdAc), caused by a mutation in a specific gene, has been documented in 37 cat breeds, with high frequency in North American and European Siamese populations. You can see a widely dilated yellow pupil, and the greenish bulging retina in the middle. When a retinal tear appears, the aqueous fluid of the vitreous may pass through the retinal hole into the space between the retina and the rear wall of the eye. The picture shows a severe case of retinal detachment. Although vitreous collapse appears usually with age and it does not cause any damage on the retina, the abnormal growth of the eye (sometimes due to myopia), inflammation or traumas may also cause a vitreous contraction. Vision loss due to retinal detachment occurs abruptly and requires immediate attention in order to preserve some retinal function and allow for the possibility. If the vitreous body is retracted, it can cause traction to a retinal fragment, leaving a tear or a hole on it. The vitreous is attached to the retina through several points. The normal ageing process can cause slimming and deterioration of the retina, but most frequently, it is the retraction of the vitreous, the jelly-like liquid that fills up the eye, which causes the deterioration and retinal tears. Most retinal detachments are caused by the presence of one or several retinal tears or holes.
