Abstract

With with use of Tono-pen, we investigated the degree of reduction in intraocular pressure of the Honan intraocular pressure reducer(HIPR) with preoperative use of dichlorphenamide and mannitol or without. Seventy five patients scheduled for cataract surgery were divided into 4 groups by preoperative medication. Intraocular pressure was measured before preoperative medication and in process of time after external compression with the Honan intraocular pressure reducer(HIPR) following retrobulbar injection. There was no additive effect on the reduction of intraocular pressure with the preoperative use of dichlorphenamide and mannitol. A rapid initial reduction in intraocular presure over the first 5 minutes of compression was followed by a more gradual reduction from 5 to 20 minutes. We concluded that the compression of up to 20 minutes duration without the preoperative use of dichlorphenamide and mannitol is adequate.
