Стан гідродинаміки ока у хворих на катаракту, ускладнену сублюксацією кришталика

Abstract

Мета роботи. Вивчити особливості гідродинаміки ока у хворих з сублюксацією кришталика. 36 patients (72 eyes) with cataract, complicated by lens subluxation, were examined. There were: men – 16 (44.4%), women – 20 (55.6%), the average age – 67.4 ± 0.6 years. In the basic group IOP was compensated in 52.8% eyes, mildly increased in 41.7%%, and considerably increased in 5.5%. In the control group in all cases IOP was within the norm ranges. We found out the increasing of aqueous humor outflow coefficient (С) to 0.19 ± 0.03 in the basic group, vs. 0.31 ± 0.05 in the control group. Average values of the production of aqueous humor were 2.61 ± 1.1 for the patients of basic group and 2.58 ± 1.3 in control group, without statistically reliable difference. Becker’s coefficient in the basic group was 141.1±9.3, and in the control group it was 84.4±8.7 (р < 0.05). It was established that lens subluxation did cause hydrodynamic disorders. They were characterized by periodic or persistent increase in the intraocular pressure on average by 14.9 % due to decrease in the aqueous humor outflow by 63.2% in significant number of patients.
