Retrospective Study on Surgical Outcomes of Congenital Cystic Dermoids in 17 Calves

Congenital cystic dermoids are rare developmental anomalies of the ocular surface in calves, potentially resulting in visual impairment, discomfort, or secondary infections if untreated. This retrospective study aimed to evaluate the clinical features, anatomical and positional classifications, surgical outcomes, and histopathological characteristics of congenital cystic dermoids in 17 calves (19 eyes). Medical records and histological data of excised tissues were reviewed. Lesions were anatomically classified as conjunctivocorneal (47.4%), conjunctival (36.8%), and conjunctivopalpebral (15.8%), and positionally based on their ocular surface location. Logistic regression analysis identified factors associated with surgical outcomes, categorized as “Good” or “Poor.” Temporal and ventrotemporal lesions were significantly associated with favorable outcomes (OR=1.64, p
