In anisocoria the pupils are not of the same size, the eyelid of the affected eye is often droopy, hence the cat is squinting one eye. The eyelid of affected eye is droopy and the cat is often squinting or rubbing the eye. This may indicate corneal injury, the central nervous system (CNS) or peripheral nerve problems, glaucoma, or inflammation in the interior of the eye. This is a condition wherein the pupils of the cat’s eyes are not of the same size. Keratoconjunctivitis sicca commonly arrives due to immune-mediated damage to the tear-producing glands or herpes virus infection. When there is little or no tear formation, eye irritation is constant and the cat will squint. Tears are necessary to remove debris and infectious agents from the eye. This is the chronic inflammation of the cornea and surrounding conjunctival tissues due to being constantly dry because of decreased tear production. This disease causes a more serious conjunctivitis than the viral ones. The symptoms also include inflamed eyes which become red and bloodshot. Even cats that have recovered from calicivirus infection can get reinfected with other strains.įeline pneumonitis is a disease that Chlamydophila felis causes. After the cat recovers, the virus “hides” in the tissues and flare-ups can occur when the cat experiences stress.įeline Calicivirus infection has the same general symptoms as feline herpesvirus infection - conjunctivitis, eye discharges and blepharospasm or squinting. There is discharge from the eyes, first watery and later becomes pus-like. Infectious diseases of the upper respiratory tract caused by viruses and bacteria cause conjunctivitis.įeline Viral Rhinotracheitis is caused by feline herpesvirus I which attacks the conjunctiva causing swelling of eyelids. Painful conditions affect the free nerve endings in the cornea and conjunctival membranes and cause blepharospasm. It is a sign that something is wrong with the eye or eyelid - usually an infection or injury, much the same as those already mentioned above. The condition usually starts with rapid eye blinking and later the eyelids will close. This is defined as the involuntary closure of the eyelids, hence squinting.

Bacterial infection, usually due to Staphylococcus, cause abscess of the glands of eyelids or a general infection of the eyelids. We will consider upper respiratory diseases below. Infections can also cause swelling of the eyelids and conjunctiva. In this condition, the edges of the eyelids are turned inwards and the eyelashes rub against the cornea. The most common of this is the condition called entropion, a congenital anomaly of the eyelid. Localized allergic reaction, example from insect bites, can also cause swelling of the eyelids and squinting.įoreign bodies that irritate the eyelids and conjunctiva can also cause squinting of the affected eye. Certain chemical substances, pellets from BB guns and small pieces of shattered glass are also common items causing trauma to the eyes and its associated structures.Īllergies, especially a generalized systemic allergic reaction from inhalant and food allergens, can cause the eyelids and conjunctiva to become reddened and swollen. Trauma may be due to a scratch, an abrasion or a laceration. The pain from the injury will cause the cat to close its eyes or squint.
