| Title | Characteristics, Etiologies, and Outcomes of Peripheral Ulcerative Keratitis in a Tertiary referral hospital in Thailand: a 10-year study |
| Purpose | To evaluate characteristics, etiologies, and outcomes of peripheral ulcerative keratitis (PUK) in Thailand. |
| Methods | Retrospective study. |
| Results | Forty-three eyes from 34 patients were enrolled with a mean age of 53.44±15.48 years. PUK affected women more than men (1.6:1) and had unilateral lesions more than bilateral lesions (2.8:1). Redness (56.3%) was the most common presenting symptom followed by pain (43.8%) and irritation (40.6%). Three most common etiologies were mooren’s ulcer (52.9%), rheumatoid arthritis (20.6%), and graves’ disease (8.8%). Corneal thinning was significantly more common in unilaterality (p=0.004) and less common in the lesion at the superior cornea (p=0.031). Perforation was found in 5 eyes (11.6%) and recurrence after treatment was found in 8 eyes (18.6%). |
| Conclusion | Nearly half of PUK is associated with several systemic causes so careful physical examination and investigation are important. Unilateral lesions could be a potential risk factor in identifying patients at risk of thinning which might prevent further damage to the eye and vision loss. |
