  • Abstract
  • Look Inside

We evaluated the barrier function of cornal epithelium induced by instillation of beta-blocker ophthalmic solution for 3 months. Fluorophotometry was used in the evaluation. Fluorescein uptake was 27.6±5.4 ng/ml in 11 eyes without medication, 22.1±2.7 ng/ml in 14 eyes treated by topical pylenoxine and 62.9±15.4 ng/ml in 21 eyes treated with 0.5% timolol malate (mean±SE) . There was a significant difference between pylenoxine and timolol groups (p<0.04). Longterm instillation of timolol malate thus produced impaired barrier function of corneal epithelium. Fluorescein uptake was independent of the duration of treatment.
