Abstract :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<0.05), while conjunctivocorneal and conjunctivopalpebral lesions were linked to poor prognosis (OR=0.49, p<0.05). Juvenil (OR=0.72, p<0.05) and concurrent signs such as epiphora, keratitis, and conjunctivitis (OR= 0.58, p<0.05) were also associated with worse prognosis. Right-eye involvement correlated with a better outcome (OR=1.63, p<0.05). Histopathological examinations revealed cystic structures lined by stratified squamous epithelium with keratin debris and inflammatory infiltration. Surgical approaches included conjunctivectomy, superficial keratectomy, and blepharoplasty, applied individually or in combination. Of the 19 eyes, 11 had good outcomes, 3 had poor outcomes, and 5 were undetermined due to incomplete follow-up. Poor outcomes were primarily associated with recurrence, ulceration, and persistent inflammation. In conclusion, lesion location, age, and clinical signs significantly influence prognosis. Optimizing outcomes in affected calves requires lesion-specific surgical strategies and tailored postoperative management.
