Prevalence of ocular lesions in cats newly diagnosed with histoplasmosis: 55 cases (2015-2022).

Objective: To describe the prevalence of ocular lesions in cats with newly diagnosed histoplasmosis.

Animals: 55 client-owned domestic cats.

Procedures: As part of this prospective case series, cats diagnosed with histoplasmosis between the years 2015 and 2020 underwent complete ophthalmic examinations by a board-certified veterinary ophthalmologist prior to the initiation of antifungal treatment.

Metastatic intraocular hemangiopericytoma in a dog.

A 10-year-old Labrador Retriever who had been undergoing therapy for a recurrent hemangiopericytoma of the right flank presented to the Kansas State University Ophthalmology service for evaluation of a painful left eye. Examination revealed secondary glaucoma and irreversible blindness of the affected eye and multifocal chorioretinal lesions in the fellow eye. Therapeutic and diagnostic enucleation of the left eye was performed and histopathologic examination demonstrated the presence of a presumed metastatic spindle cell sarcoma.

Measurement of plasma gentamicin concentrations postchemical ciliary body ablation in dogs with chronic glaucoma.

Objective: To investigate the absorption of gentamicin into the plasma after an intravitreal injection in dogs and to report the success rate of this procedure in lowering the intraocular pressure.

Animals: Twenty-four client-owned dogs with chronic, end-stage glaucoma.

Procedures: Dogs received a unilateral (22) or bilateral (2) intravitreal injection of 25-40 mg of gentamicin (mean ± SD dose 2.

Treatment of six cases of equine corneal stromal abscessation with intracorneal injection of 5% voriconazole solution.

Objective: To describe a reproducible technique for intrastromal injection in the standing horse for treatment of corneal stromal abscessation.

Animal Studied: A retrospective clinical study addressing the history, treatment, and outcome of six equids (six eyes) that received intrastromal voriconazole injection.

Procedure: Equids having a deep stromal abscess suspected to be of fungal origin were administered intrastromal injection of 5% voriconazole solution under standing sedation in an effort to bring about enhanced resolution of clinical disease.

Calcific band keratopathy in an alpaca.

A 4-year-old female Suri alpaca was presented for evaluation of acute onset weakness, lethargy, and recent development of opacities in both eyes. On ophthalmic examination, bilaterally symmetrical corneal opacities were noted along the interpalpebral fissures with a few corneal blood vessels intermingled. A presumed diagnosis of calcific band keratopathy was made based on location and appearance.

Comparison of efficacy and duration of effect on corneal sensitivity among anesthetic agents following ocular administration in clinically normal horses.

Objective: To compare efficacy and duration of effect on corneal sensitivity of 0.5% proparacaine hydrochloride, 0.5% bupivacaine hydrochloride, 2% lidocaine hydrochloride, and 2% mepivacaine hydrochloride solutions following ocular administration in clinically normal horses.

Treatment of dematiaceous fungal keratitis in a dog.

Case Description: A 9-year-old castrated male Bichon Frise was evaluated because of a 3-week history of a nonhealing corneal ulcer and corneal pigmentation of the left eye.

Clinical Findings: Ophthalmic examination of the left eye revealed conjunctival hyperemia, corneal neovascularization, corneal edema, corneal ulceration, and central corneal pigmentation. Intraocular structures of the left eye could not be visually examined because of the diffuse nature of the corneal lesions.
