Corneal and conjunctival sensitivity in rosacea patients.

PURPOSE: To assess corneal and conjunctival sensitivity in rosacea patients.

METHODS

A total of 55 patients with rosacea and 37 control subjects participated in the study. Corneal and conjunctival sensitivity was determined by Cochet-Bonnet esthesiometer. Subjective symptoms of ocular dryness were evaluated using Ocular Surface Disease Index (OSDI). Schirmer's I test (ST), tear breakup time (tBUT) and ocular surface staining with fluorescein were carried out to measure objective signs.

RESULTS

The mean corneal and conjunctival sensitivity did not differ significantly between rosacea patients and controls (all p > 0.05). Schirmer's I test and tBUT were significantly reduced (p = 0.004 for OD and p < 0.001 for OS) and grade of ocular surface staining was significantly high (p = 0.018 for OD and p = 0.038 for OS) in rosacea patients. Corneal and conjunctival sensitivity did not show significant correlation with ST, tBUT, ocular surface staining (Oxford Schema), duration of rosacea and OSDI score.

CONCLUSIONS

Corneal and conjunctival sensitivity did not change significantly in rosacea.
