It has been noted that affected cats tend to be dominating rather than submissive; some research argues that feline hyperesthesia syndrome is a form of conflict displacement, rather than just a form of general behavioural displacement, wherein the affected cat acts out thwarted territorial disputes on its own body. [9]
Other symptoms include dilated pupils and decreased pupillary light reflex. Fundoscopy to examine the retina will show shrinking of the blood vessels, decreased pigmentation of the nontapetal fundus , increased reflection from the tapetum due to thinning of the retina, and later in the disease a darkened, atrophied optic disc .
Affected cats may also display poor judgement of distance, and some cats may develop a rapid, crouching, hypermetric gait. Some affected cats may exhibit an abnormal head tilt, tremors, a vacant stare, excessive salivation, decreased grooming behaviors, polyphagia , and dilated pupils. [ 3 ]
Symptoms include sudden permanent blindness, but may occur more slowly over several days, weeks or months, [3] dilated pupils. Pupillary light reflexes are usually reduced but present; the slow phase mediated by melanopsin in retinal ganglion cells is retained.
Diabetes, for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
People taking Ozempic and Wegovy may be at increased risk of developing a debilitating eye condition that can cause irreversible vision loss, a study published in JAMA Ophthalmology finds.
Dysautonomia is primarily seen in cats. Symptoms include vomiting, depression, anorexia, weight loss, dilated pupils, third eyelid protrusion, sneezing, slow heart rate, and megaesophagus. The prognosis is poor and supportive treatment is necessary. Recovery in cats may take up to one year. [10]
The ptosis from inactivation of the superior tarsal muscle causes the eye to appear sunken in, but when actually measured, enophthalmos is not present. The phenomenon of enophthalmos is seen in Horner's syndrome in cats, rats, and dogs. [5] Sometimes there is flushing on the affected side of the face due to dilation of blood vessels under the skin.
