![]() If complete blindness was present when the pupils were dilated a year ago, it isn't too likely that treatment at this time would make a difference. Mary Glaze spoke at last month and she said she had seen some come back after a month of blindness. While I can't remember a patient who recovered after more than a week of being blind, I was at a seminar on ophthalmology that Dr. If the high blood pressure is treated immediately there is a chance that the subsequent damage can be avoided. The most common cause of retinal atrophy in cats is high blood pressure leading to retinal detachment, leading to retinal atrophy. I felt that confirming the diagnosis and knowing that I didn't make a mistake and miss a treatable condition was worthwhile. I did this even though I knew that there was no hope for treatment. I can say this with absolute certainty because I diagnosed this problem in my own dog and immediately took her to an ophthalmologist for confirmation. If this were my cat, I would be asking for referral to a veterinary ophthalmologist for confirmation of the diagnosis of retinal atrophy. I want to get this in first before I go on, in case I forget. He can still see somewhat, and doesn't have to much problem in getting around, is there anything to prevent further deterioration? The vet checked and said every thing was fine, we just went for another check up and she told me he has this. Sudden Onset Blindness Due to HypertensionĬan you tell me anything about Retinal Atrophy, and hope for some kind of recovery? I noticed about a year ago my 13 year old male cat's pupils were always enlarged. ![]() Problem with Remaining Eye After One Eye RemovedĬonjunctivitis Not Responding to Treatment Visceromotor nerve axons (which constitute a portion of cranial nerve III, along with the somatomotor portion derived from the Edinger-Westphal nucleus) synapse on ciliary ganglion neurons, whose parasympathetic axons innervate the iris sphincter muscle, producing miosis.The following are real life cases of Eye problems in Cats that have been treated by Dr. From the pretectal nucleus neurons send axons to neurons of the Edinger-Westphal nucleus whose visceromotor axons run along both the left and right oculomotor nerves. Nerves involved in the resizing of the pupil connect to the pretectal nucleus of the high midbrain, bypassing the lateral geniculate nucleus and the primary visual cortex. The retinal photoceptors convert light stimuli into electric impulses. Signals from photosensitive ganglion cells have multiple functions including acute suppression of the hormone melatonin, entrainment of the body's circadian rhythms and regulation of the size of the pupil. The ganglion cells give information about ambient light levels, and react sluggishly compared to the rods and cones. Light entering the eye strikes three different photoreceptors in the retina: the familiar rods and cones used in image forming and the more newly discovered photosensitive ganglion cells.
