Recurrent vs. Nonrecurrent Superficial Non-Healing Corneal Ulcers in Cats: A Multifactorial Retrospective Analysis

Year: 2025

Type: article

Abstract: Feline superficial non-healing corneal ulcers are persistent lesions requiring individualized treatment to reduce recurrence. This retrospective study evaluated 136 affected eyes (113 nonrecurrent; 23 recurrent) to identify clinical and treatment-related factors associated with recurrence. Recurrent ulcers were more common in older cats (7.2 ± 4.3 vs. 5.1 ± 4.6 years; p = 0.026). Domestic Shorthairs were the most frequently affected breed (50%), and central ulcer location predominated in both groups. Recurrent cases required more intensive management, with 16.9% needing ≥ 2 treatment courses, compared to 83% of nonrecurrent cases resolving after a single course. Healing time following corneal debridement was longer in recurrent cases (32.3 ± 34.4 vs. 25.5 ± 23.1 days; p = 0.272), and corneal sequestrum occurred more frequently (13.0% vs. 10.6%; p = 0.735). Corneal debridement was the primary treatment modality. Systemic medications were more often used in recurrent cases, notably oral lysine (47.8% vs. 26.5%; p = 0.049) and famciclovir (17.4% vs. 2.6%; p = 0.016). Recurrent cases also showed significantly higher rates of concurrent viral (p < 0.001) and bacterial/fungal infections (p = 0.027). In conclusion, recurrent superficial non-healing corneal ulcers were associated with age and systemic illness, emphasizing the need for early diagnosis and management of underlying conditions.
