Definition:
Corneal dystrophy is a collection of disorders that is characterized by a non-inflammatory and inherited opacity of the eye’s cornea. It is a common disorder in dogs and rarely seen in cats.
The types of corneal dystrophies largely depend on the particular location of the cornea affected, including posterior, stromal and anterior layers.
Diagnosis:
Diagnosis is made by eye examination, fluoroscein dye test and Schirmer’s tear test, depending on the symptoms present.
Treatment:
Corneal dystrophy is a progressive and irreversible condition. As such, no treatment could restore the damages caused by corneal dystrophy. Treatments available, such as antibiotics and sodium chloride ointments, are used to alleviate symptoms and prevent progression. Severe cases of corneal dystrophy may require surgery.
Symptoms and Signs:
The early stages of corneal dystrophy have no significant symptoms. However, it can cause corneal ulceration and epithelial dystrophy. The cornea may appear cloudy with circles and grayish white lines. Some develop a crystalline appearance.
Causes:
An accumulation of materials in the cornea, such as cholesterol crystals and lipids could cause corneal dystrophy.
