Therapeutic Management of Corneal Ulcer - A Report of 2 Horses.
Corneal ulcer was diagnosed in two horses using fluorescent dye test. Treatment was started with topical and subconjuctival injection of Gentamicin and NSAID eye drops. After 10 days, flourescein strip was negative and complete healing was observed in fifteen days.

Corneal ulcerations is in horses can range from simple, superficial breaks or abrasions in corneal epithelium to full thickness corneal perforations with iris prolapse. The prominent eye in equines predisposes it to traumatic corneal injuries. Iridocyclitis is present in all types of equine corneal ulcers and must also be treated to preserve vision. Globe rupture, phthisis bulbi and blindness are possible sequelae to corneal ulceration in equines. Horse cornea's also demonstrate a pronounced fibrovascular healing response (Brooke, 1999).
History and Diagnosis
Two horses working at road side industry environment were presented with profuse lacrimation, blepharitis and irritation. Initial treatment with Dexamethasone and Ciprofloxacin eye drops was futile. Diagnosis of corneal ulcer was primarily based upon history, clinical signs, clinical examination and confirm by using fluorescent strip test (Fig. 1-3).
Treatment and Discussion
Eye was washed with 0.9% NaCl. Subconjuctival injection of Gentamicin 0.5 ml was started on alternate day. Owner was advised for topical use of Diclofenac (NSAID) and Gentamicin eye drops q.i.d. Eye was bandaged to protect from dust. After 10 days, fluorescein test was found negative. Horses working at brick kiln are prone to corneal ulcer due to dusty environment where foreign bodies produce irritation in eye leading corneal injuries. Recovery rate of corneal ulcer is mostly dependent upon early diagnosis and treatment. All corneal injuries should be fluorescein stained to detect corneal ulcers. Fluorescein dye retention is diagnostic of full-thickness epithelial defect or corneal ulcer, these corneal ulcers
frequently culminate in loss of eye vision as a result of endophthalmitis, anterior chamber collapse and glaucoma or chronic leakage of aqueous humour, leading to atrophy of ciliary body and phthisis bulbi (Felberg, 2003). The treatment of corneal ulcers in horses involves medical therapy alone or a combination of medical and surgical therapy (Heidi, 2004).
