Abstract

We investigated the conjunctival sensitivity of bleb area after successful trabeculectomy for 3 to 6 months in 19 eyes of 16 patients using Cochet-Bonnet aesthesiometer(diameter=0.12mm). The conjunctival sensitivity of bleb area was decreased significantly from 68.78mg/S to 171.05mg/S compared to the preoperative values. This decrement was maintained during the follow-up period and not related to the type, height and vascularity of the bleb. This results shows that the conjunctival sensitivity of bleb area after successful trabeculectomy is significantly decreased and maintained at least 3 months after operation. Therefore the conjunctival sensitivity of bleb area might be considered possible indicator of success or failure during follow-up period after trabeculectomy.
