Plain-English summary
A group of 55 domestic cats diagnosed with histoplasmosis (a fungal infection) underwent eye exams before starting treatment. Out of these cats, 45 showed signs of eye problems, such as inflammation and damage to the retina. The most common issues included chorioretinitis and partial retinal detachments, which can lead to vision loss. This highlights the importance of thorough eye examinations for cats with histoplasmosis to catch any potential eye issues early on.

Abstract
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. Histoplasmosis was diagnosed by consistent clinical findings and identification of Histoplasma yeast on pathology or by the use of a commercially available enzyme immunoassay to detect Histoplasma antigen in urine. RESULTS: Of the 55 cats, 45 (82%; 95% CI, 72% to 92%) had signs of active anterior, posterior, or panuveitis. The most common lesions were identified in the posterior portion of the globe and included chorioretinitis and partial retinal detachments (44/55 [80%; 95% CI, 69% to 90%] cats). CLINICAL RELEVANCE: Detailed ophthalmic examinations should be performed on all cats with diagnosed or suspected histoplasmosis, as ocular involvement and subsequent vision loss are common.
