Primary or essential if it exists in the cat.Most commonly sudden visual loss and/or intra-ocular hemorrhage (note that sudden visual loss accompanies detachment in the second eye where the first may be chronically blind).Prognosis: previously considered to be poor unless treatment instituted very early degeneration of feline retina is rapid following detachment more recently treatment of hypertensive detachments with amlodipine has resulted in recovery of sight in a significant proportion of animals.Treatment: depends on cause - treat primary cause and symptomatic management.Diagnosis: ophthalmoscopy reveals detachments and hemorrhage.Signs: any or all of: visual loss/compromise (often sudden onset may be difficult to appreciate if retinal detachment is unilateral), hyphema, vitreal hemorrhage, dilated pupil, leucocoria (white pupil). Also inflammation, trauma, neoplasia, hyperviscosity syndromes, toxicity (ethylene glycol).
