New information about the causes of eye irritation in rosacea and proper skin care were among the rosacea-related topics presented to dermatologists attending the recent 71st annual meeting of the American Academy of Dermatology (AAD) in Miami Beach.
While a wide-ranging variety of potential factors may be involved in the development of rosacea, Demodex mites are a common link between those with rosacea of the facial skin and those with eye irritation from ocular rosacea, according to Prof. Frank C. Powell, consultant dermatologist at Mater Misericordiae Hospital in Dublin, Ireland, and member of the National Rosacea Society Medical Advisory Board.1
Dr. Powell noted these microscopic mites, which appear in greater numbers in individuals with rosacea than in those without the condition, can be found in a special form of cylindrical dandruff often seen on the eyelashes of individuals with subtype 4 (ocular) rosacea.
At the same meeting, Dr. Diane Berson, associate clinical professor of dermatology at Cornell University, noted that some topical over-the-counter products may be helpful in calming the sensitive red skin of subtype 1 (erythematotelangiectatic) rosacea, and appropriate skin care is essential. This may include gentle cleansing, moisturizing, sun protection and cosmetics to camouflage redness.
