PWS symptoms can range from poor muscle tone during infancy to behavioral problems in early childhood. Some symptoms often found in infants, besides poor muscle tone, are a lack of eye coordination; almond-shaped eyes; thin upper lip; and, due to poor muscle tone, lack of a strong sucking reflex.
These symptoms may develop over a few months preceding the onset of SARDS. [4] Clinical signs and disease progression vary markedly among individual animals, depending on the number and type of hormones that are increased, the degree of hormone elevation, and the age of the dog. [5]
Retinal dysplasia is an eye disease affecting the retina of animals and, less commonly, humans. It is usually a nonprogressive disease and can be caused by viral infections, drugs, vitamin A deficiency, or genetic defects. Retinal dysplasia is characterized by folds or rosettes (round clumps) of the retinal tissue.

Horner's syndrome* results from damage to the sympathetic innervation of the eye. Signs include enophthalmos (sunken eye), miosis (small pupil), elevated third eyelid, and ptosis (drooping of the upper eyelid). Usually the syndrome in dogs is idiopathic, but it can also be caused by trauma, tumors, or ear infections. [73]
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.
“Cherry eye is a common eye condition in dogs where a gland in the third eyelid pops out and swells up, making it look like a red, swollen ‘cherry’ in the corner of the eye,” says Dr. Hood.
Frontonasal dysplasia (FND) is a congenital malformation of the midface. [1] For the diagnosis of FND, a patient should present at least two of the following characteristics: hypertelorism (an increased distance between the eyes), a wide nasal root, vertical midline cleft of the nose and/or upper lip, cleft of the wings of the nose, malformed nasal tip, encephalocele (an opening of the skull ...
