Abstract

In the diagnosis of primary open angle glaucoma, it is very important to evaluate the outflow facility and intraocular pressure. Although tonography affords one of the most convenient methods for the estimating the outflow facility, there have been many efforts to overcome its inhernt inaccuracy. Honan introcular pressure reducer(HIPR) is widely used prior to cataract surgery because it is believed to be clinically safe and effective in reducing intraocular pressure, vitreous volume and the risk of vitreous loss. For the evaluation of the effects of HIPR in relation to outflow facility, the intraocular pressures were measured with applanation tonometer in 30 nonglaucomatous and 30 glaucomatous patients before and immediately after the application of HIPR at a pressure 30mmHg for 30 minutes, and then repeatedly at 5-minute intervals for 30 minutes thereafter. The results were as follows; 1. Mean initial IOPs were 15.6 +/- 2.71mmHg in nonglaucomatous patients and 20.7 +/- 2.71mmHg in glaucomatous patients. 2. Mean IOPs immediately after commpression were 4.3 +/- 1.38mmHg in nonglauco matous patients and 10.3 +/- 0.95mmHg in glaucomatous patients. 3. Mean IOP reductions were 11.20 +/- 1.89mmHg in nonglaucomatous patients and 10.45 +/- 1.69mmHg in glaucomatous patients. 4. Mean IOP reduction rates were 72.8% in nonglaucomatous patients and 50.3% in glaucomatous patients. 5. Mean IOP recovery times were 24.5 minutes in nonglaucomatous patients and more than 30 minutes in glaucomatous patients. 6. Rates of IOP recovery after 25 minutes elapsed were 76.6% in nonglaucomatous patients and 10% in glaucomatous patients. On the basis of the results HIPR may be considered to be beneficial in clinical diagnosis of open angle glaucoma.
