RESUMO
Objective To quantify aqueous flare and cells in the eyes of healthy subjects and to evaluate the effect of age and sex on the blood aqueous barrier. Design Prospective case series. Participants Four hundred and forty-two eyes of 221 healthy sub- jects. Methods Aqueous flare and cells of 442 eyes were evaluated with FC-2000 laser flare cell meter (LFCM). Main Outcome Mea- sures Aqueous flare and cells. Results The mean flare values of all of eyes was 4.7?2.9 pc/ms, it was 3.1 pc/ms in the age group of less than 10 years, 3.8 pc/ms in the age group of 40-49 years and 11.0 pc/ms in the age group of 80 years or over. The mean flare val- ues in the age groups of 50 years or over were significantly higher than that in the age group of 40-49 years (P
RESUMO
Suprofen eye drop was instilled into one eye of 10 pigmented rabbits and then anterior uveitis was induced by intraperitoneal injection of endotoxin of Shigella flexneri serotype 1A to evaluate the effects of non-steroidal anti-inflammatory drug on endotoxin induced uveitis. The pupillary diameters were measured, and aqueous cell and flare gradings were recorded in 20 eyes of 10 rabbits for one week at an interval of 12 hours for the first 24 hours and then every 24 hours for a week. A difference between the treated and control groups were investigated. All the above parameters showed greatest changes at 12 or 24 hours after injection and became normal by one week. The two groups demonstrated statistically significant difference at 12 hours, day 1 and day 2 as for pupillary diameter, at day 1 and day 2 as for cell and at 12 hours and day 1 as for flare. Thus, it can be concluded that prostaglandins play a role in miosis, in the appearance of inflammatory cells and flare in endotoxin induced uveitis and the topical administration of non-steroidal anti-inflammatory drug can alleviate signs of anterior uveitis. Specific relationship between leukotriene B4 and aqueous cell was not demonstrated.
