Abstract:
To study the effect of postural change on intraocular pressure ( lOP ) fluctuation in open angle glaucoma patients after trabeculectomy, and to discuss the value of this investigation on prognosis.METHODS:Fifty-one cases (62 eyes) of primary open angle glaucoma were selected as the research object. Perkins ophthalmotonometer was used to test lOP at the time when patient seat ( first seat ) . The patients were asked to lie supine for 25min, detected lOP, and the patients seated again (final seat), sustaining for 15min, detected lOP. According to whether the lOP range was more than 5mmHg, they were divided into high volatility fluctuation group and low volatility fluctuation group. We recorded their visual field progression ( with AGlS score) , HPA staging, in order to evaluate the correlation of lOP range with them. Reviews were made 3mo a time, and lasted for 1a, in order to evaluate the relation between lOP range and AGlS scores.RESULTS: The lOP of first seat was 18. 1+2. 2mmHg. There was no significant difference in the same position (P>0. 05 ). The lOP range was 4. 1 ± 1. 5mmHg. Low volatility fluctuation group was more likely to have low AGlS score and to be early vision HPA ( P<0. 001, P<0. 05 ) . There were significantly positive correlation between lOP range and AGlS (r=0. 412, P<0. 001); With time increasing, the number of patients whose visual field progression was increased, and the lOP was also raised. At any time the two were positively correlated (P<0. 01).CONCLUSlON:Visual field progression is related to the degree of lOP fluctuation in open angle glaucoma patients after trabeculectomy, so we can predict the prognosis of patients simply by detect lOP fluctuation. This is good to adjust the lOP control scheme.
