Objective: To determine the prevalence of ocular surface disease and visual outcome in mexican patients with ocular rosacea. Methods: Observational, descriptive and retrospective study of patients with acne rosacea and/or ocular rosacea seen at Instituto de Oftalmología y Ciencias Visuales, Tecnológico de Monterrey. Analyzed parameters included: demographics, clinical manifestations, ocular surface findings, and visual outcome. Results: We analyze 55 patients, 23 (41.8%) male and 32 (58.2%) female, with a mean age of 57.3 years. All patients had ocular rosacea; 76.45% of them had flush erythema and 74.5% rinophyma, 63.6% had red eye, 83.6% had meibomian gland dysfunction, 50.9% superficial punctate keratitis, 16.3% corneal infiltrates, and 20% pannus. While patients with no corneal involvement had a mean VA of 0.33-LogMAR (20/40) those with corneal disease had a mean VA of 0.75-LogMAR (20/114) (p<0.05). Discussion: Ocular rosacea is a dermato-ocular disease which may significantly affect the ocular surface. The present study shows that 83.3% of patients had tear film instability, and more than half (65.45%) of them showed corneal changes. Visual outcome was significantly worse in those patients with corneal involvement. Conclusions: In the present study, ocular rosacea presented most commonly in women, although men showed a more severe form of the disease. Chronic blepharitis was the main ocular manifestation however corneal involvement was more common than what has been reported in the literature. © 2012 Sociedad Mexicana de Oftalmología.
