Manifestations of ocular rosacea in females with dark skin types

BACKGROUND: Current knowledge about ocular rosacea in dark skin individuals is lacking. The prevalence of ocular rosacea varies considerably among studies and is probably higher than previously presumed. OBJECTIVE: To estimate the prevalence and pattern of ocular rosacea among dark skinned female patients, compare it with fair skinned, and to correlate the severity of cutaneous disease with ocular findings. METHOD: Female patients diagnosed with rosacea between 2011 and 2013 were studied prospectively. They were referred to ophthalmology for clinical observations and slit lamp examination. In all patients Schirmer and Tear break up time tests to diagnose dry eye were performed. RESULT: Fifty six consecutive female patients, joined the study with different skin types ranging from skin type 4 to 6. A total of 43 patients (76.8%) were positive for ophthalmologic findings. The most frequent symptoms were itching, burning sensation and redness, while the most frequent signs were meibomian gland dysfunction, dry eyes, eyelid telangiectasia and irregular margin. Significant correlation was noted between meibomian gland dysfunction and irregular lid margin (P = 0.003). Dry eye and Schirmer test significantly correlated with eye lid telangiectasia (p = 0.004; 0.015) respectively. No significant correlation was found between the severity of cutaneous disease and ocular findings. CONCLUSION: Ocular rosacea in dark skinned females is a common presentation and is comparable to that reported for fair skin, with eyelid telangiectasia and meibomian gland dysfunction being early phenomena. Earlier onset and more benign course were seen compared to other studies. Ocular and cutaneous rosacea are independent of each other.
