The cause of rosacea is actually easy to understand. It is caused by a blood vessel disorder in a person which causes his blood vessels to swell up which leads to the deeply flushed look. Highly acidic foods and drinks are the main triggers in rosacea sufferers, although excessive external heat or cold can also be factors, as can things that are abrasive upon the skin such as abrasive cleansers or high winds.
In about half of all rosacea sufferers there also occurs ocular rosacea. Ocular rosacea is a persistent burning or irritation feeling in the eyes and is accompanied by blood shot aqueous humors, red-rimmed eyes, and sometimes swollen eyes. In addition to these aggravations, the eyelashes might begin to fall out. Ocular rosacea can, though it usually does not, become keratitis. Rosacea keratitis has an extremely unfavorable prognosis and can lead to coronal opacity and blindness. The most signs of ocular rosacea include scaly, encrusted eyelids that are chronically inflamed and constantly in need of flushing out, cleansing, or rubbing. These symptoms often never get any worse, but they are unpleasant in their own right. Sufferers of ocular rosacea have to keep in mind that their eyes have become exceedingly sensitive to sunlight and even in the early morning or at sundown they might not be able to go outside without wearing thick or polarized sunglass lenses. Ocular rosacea does not progress or egress in any proportion to the rosacea of the skin. Mainly, tetracycline is used to treat ocular rosacea. However, the antibiotic usually must be taken every day for several weeks before the symptoms begin to be alleviated. In addition to taking tetracycline, the sufferer should stay out of the sunlight and keep the lights as dim as possible in the home during the treatment. The tetracycline dosage will be adjusted by the doctor after he assesses how well the therapeutic response is coming along. |
