12/25/2023 0 Comments Detached retina in cats![]() Post-detachment retinal degeneration is characterised by retinal vessel attenuation and tapetal hyperreflectivity. The more chronic the detachment, the less likely that vision will return, even though the retina may reattach. The detached retinal part will not function properly and blurriness or a black spot in vision will appear. An estimated 70 of cats experience improvement in ocular signs, including return of vision, in response to amlodipine. This is how the retina starts to progressively detach from the eye wall. 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. 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. If the vitreous body is retracted, it can cause traction to a retinal fragment, leaving a tear or a hole on it. ![]() There are two main forms of PRA recognized in cats, an early onset, inherited from called retinal dysplasia and a late onset form. With this disease, the cells deteriorate over time eventually leading to blindness in the affected cat. Also taking precaution in cleaning cat litter boxes or handling outdoor cats. Progressive retinal atrophy (PRA) is a group of degenerative diseases that affect photoreceptor cells in the eyes. The vitreous is attached to the retina through several points. Serous Detachment of Retina Retinal Inflammation Retinal Infections Retinal. 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. ![]()
