The most common eye diseases
Eye diseases are common in pets and can be extremely painful. The most common include corneal ulcers (erosions and ulcerations), glaucoma (elevated intraocular pressure), dry eye (keratoconjunctivitis sicca), cataracts (lens opacity), and eyelid conditions such as entropion (inward-turning eyelid) and ectropion (outward-turning eyelid). Certain breeds, particularly brachycephalic (short-nosed) dogs, are especially prone to eye problems.
Examination methods
Eye examination uses several diagnostic methods. Fluorescein staining reveals corneal damage and ulcers. Intraocular pressure measurement (tonometry) identifies glaucoma. The Schirmer tear test measures tear production. Slit lamp examination assesses the structures of the anterior segment. These examinations provide a precise picture of the eye's condition and allow appropriate treatment to be initiated.
Treatment
Treatment of eye diseases depends on the diagnosis. Corneal ulcers are treated with eye drops and, when necessary, with a protective contact lens or surgically. Glaucoma is managed with pressure-lowering medications. Dry eye is treated with tear substitutes and immunomodulatory drops. Entropion and other structural eyelid problems often require surgical correction.
When to seek examination?
Eye symptoms should be addressed promptly, as many eye diseases progress rapidly and can lead to permanent vision loss. Seek veterinary care if your pet is squinting, the eye is watering, the eye is red, the pupils are unequal in size, the eye appears cloudy, or your pet is pawing at its eye. Early treatment is particularly critical in eye diseases.
Frequently asked questions about eye diseases
<strong>Are eye diseases hereditary?</strong> Many eye diseases are hereditary or breed-related. Brachycephalic (short-nosed) breeds such as Pugs and English Bulldogs are predisposed to corneal damage and dry eye. Cocker Spaniels and Poodles are prone to cataracts, and Collies to retinal diseases. Screening for hereditary eye diseases is part of breeding evaluations. <strong>How quickly should I seek treatment?</strong> With eye symptoms, speed is crucial. A corneal ulcer can deepen within 24 hours without treatment, and glaucoma can lead to permanent blindness within hours. If your pet is squinting, the eye is red or cloudy, or the pupils are unequal in size, seek veterinary care the same day. Eye symptoms do not resolve on their own.
