Cat-eye syndrome (CES) or Schmid–Fraccaro syndrome is a rare condition caused by an abnormal extra chromosome, i.e. a small supernumerary marker chromosome. [2] This chromosome consists of the entire short arm and a small section of the long arm of chromosome 22. In consequence, individuals with the cat-eye syndrome have three (trisomic) or ...
Chromosomal Mutation. Cri du chat syndrome is a rare genetic disorder due to a partial chromosome deletion on chromosome 5. [1] Its name is a French term ("cat-cry" or "call of the cat") referring to the characteristic cat-like cry of affected children (sound sample [1]). [2] It was first described by Jérôme Lejeune in 1963. [3]

Cat-scratch disease (CSD) is an infectious disease that most often results from a scratch or bite of a cat. [4] Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. [2] People may feel tired, have a headache, or a fever. [2] Symptoms typically begin within 3–14 days following ...
Toxoplasma gondii. Toxoplasma chorioretinitis, more simply known as ocular toxoplasmosis, is possibly the most common cause of infections in the back of the eye (posterior segment) worldwide. The causitive agent is Toxoplasma gondii, and in the United States, most cases are acquired congenitally. The most common symptom is decreased visual ...
Progressive retinal atrophy. 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.
As a progressive, chronic condition, signs and symptoms of Fuchs dystrophy gradually progress over decades of life, starting in middle age. Early symptoms include blurry vision upon wakening which improves during the morning, [2] as fluid retained in the cornea is unable to evaporate through the surface of the eye when the lids are closed overnight.
The eye develops in utero during the first three months of pregnancy, and a gap called the choroidal fissure appears at the bottom of the stalks that eventually form the eye, the AAO explains.
