Six horses with corneal disease were evaluated via UBM for lesion size, lesion depth, and continuity of Descemet's membrane.

UBM evaluation of three cases of corneo\u2010limbal squamous cell carcinoma yielded information regarding lesion depth for planning of keratectomies using fixed\u2010depth keratomes and subsequent \u03b2\u2010radiation therapy. Corneal depth and continuity of Descemet's membrane were determined in two horses with stromal abscesses and allowed for planning of therapeutic options. In one horse with a corneal foreign body, UBM contributed to accurate assessment of the foreign body's stromal depth, which could not be assessed during ophthalmic examination due to extensive corneal cellular infiltrate. The information regarding corneal depth allowed for more accurate pre\u2010surgical planning in patients with opaque corneal
