ABSTRACT
Objective:To observe the differences in scleral lamina curvature (SLC) of patients with pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG), and primary chronic angle-closure glaucoma (CPACG) were compared and analyzed and their significance was analyzed.Methods:A retrospective clinical study. From June 2017 to December 2020, 30 PXG (PXG group), POAG (POAG group) and CPACG patients (CPACG group) diagnosed at Eye Center of Cangnan County people's Hospital of Zhejiang Province (Cangnan Hospital Affiliated to Wenzhou Medical University) were included in the study. The age difference between the three groups of patients was statistically significant ( t=17.925, P=0.001); gender composition ratio ( χ2=2.158, P=0.276), intraocular pressure ( t=4.993, P=0.078), and axial length ( t=1.956, P=0.532), central corneal thickness ( t=1.407, P=0.724), average visual field defect ( t=2.725, P=0.496), optic disc retinal nerve fiber layer thickness ( t=2.185, P=0.492) in comparison, the differences were not statistically significant ( P>0.05). The frequency-domain optical coherence tomography deep-enhanced imaging (OCT EDI) technology was used to measure the average and 0°, 30°, 60°, 90°, 120°, 150° SLC of the affected eyes, and calculate the SLC index (SLCI) and SL curve depth (SLCD). Quantitative data comparison between groups used independent sample t test. Count data comparison used χ2 test. Univariate and multivariate logistic regression analysis were used for correlation analysis. Results:The results of OCT EDI examination showed that the SLC of eyes with PXG and CPACG was significantly steep, while the SLC of eyes with POAG was relatively flat. Except for the angle of 150°, the other 6 angles of SLCI and SLCD in the PXG group and CPACG group were higher than those in the POAG group, and the differences were statistically significant ( P<0.05). However, there was no statistically significant difference between PXG group and CPACG group for 7 angles of SLCI and SLCD ( P>0.05). Logistic regression analysis showed that the average SLCI [odds ratio (OR)=1.498, 95% confidence interval ( CI) 1.137-2.018, P=0.001], age ( OR=1.074, 95% CI 1.019-1.143, P=0.016) was significantly correlated with PXG; mean SLCI ( OR=1.625, 95% CI 1.192-1.997, P=0.001), intraocular pressure ( OR=1.383, 95% CI 1.106-1.993, P=0.012) was significantly correlated with CPACG. POAG group ( β=0.143, 95% CI 0.032- 0.208, P=0.016), CPACG group ( β=0.132, 95% CI 0.079-0.315, P=0.043) intraocular pressure was correlated with mean SLCI; all factors of PXG group were correlated with SLCI without correlation ( P>0.05). Conclusion:Compared with POAG, the SLC of eyes with PXG and CPACG is steeper and related to disease occurrence.
ABSTRACT
Objective:To evaluate the early analgesic effect of new non-steroidal anti-inflammatory drugs 0.1% bromofenac sodium hydrate eye drops in pterygium surgery and the efficacy and safety on relieving the irritative symptoms.Methods:One hundred patients (112 eyes) with pterygium who were treated in Cangnan People′s Hospital (Cangnan Hospital Affiliated of Wenzhou Medical University) from January 2016 to September 2017 were selected and divided into observation group and control group by the hospital sequence, with 50 patients in each group. Before operation and 7 d after operation, the patients in two group were given topical tobramycin eye drops (4 times a day), and the patients in observation group were given 0.1% bromofenac sodium hydrate eye drops twice a day on the base of tobramycin eye drops. The patients were investigated early after operation and the pain scores of the two groups were compared 6, 8, 24, 48 and 72 h after operation.The corneal epithelial healing was compared too.Results:The pain scores in observation group 6, 8, 24, 48 and 72 h after operation were significantly lower than that in control group [(0.96 ± 0.13) scores vs. (2.21 ± 0.07) scores, (0.90 ± 0.05)scores vs. (1.71 ± 0.30) scores, (0.71 ± 0.07) scores vs.(1.54 ± 0.09) scores, (0.51 ± 0.04) scores vs. (1.31 ± 0.10) scores, (0.21 ± 0.02) scores vs. (0.80 ± 0.1) scores], and the differences were statistically significant ( P<0.05). The corneal wound healing rate of the two groups 2 or 3 d after operaion had no significant differences and the corneal wound healing rate 7 d after operaion was 100.0% (57/57, 55/55) in two groups. Conclusions:In pterygium surgery patients, using 0.1% bromfenac sodium hydrate drops before and after operation to relieve pain is valid, and can effectively relieve early postoperative pain.
