Eye rubbing-induced changes in intraocular pressure and corneal thickness measured at five locations, in subjects with ocular allergy.

摘要: AIM To assess the effects of eye rubbing on corneal thickness (CT) and intraocular pressure (IOP) measurements obtained 0-30min after habitual in symptomatic patients. METHODS Measurements IOP CT were at five locations (central, temporal, superior, nasal inferior) before, every 5min for 30min interval 30s rubbing, 25 randomly selected eyes 14 subjects with ocular allergy 11 age-matched normals. Differences calculated each group [Baseline minus recorded time (for IOP), location CT)] comparison then made between groups (allergic versus control) differences any observed effects. RESULTS Within groups, baseline mean IOPs allergic patient-group (14.2±3.0 mm Hg) control (13.1±1.9 similar all times, (P >0.05, all). The maximum reduction was 0.8 Hg increase also subjects. Between control), changes remained under 1 times (P=0.2) rubbing. 0 central (CCT), inferior (ICT), superior (SCT), temporal (TCT) (NCT) did not vary significantly from values allergic-subject (P>0.05, both). both (P>0.05) except TC which minimally thinner by about 4.4 µm (P=0.001) than subjects, following CONCLUSION measured comparable that normal 30min. Although, to those it varied +10 -7.5 cornea showing consistent reductions allergy. However, this minimal considered be clinically relevant.
