Abstract

Background: This study was aimed to compare the effect of laser photocoagulation (LF), intravitreal bevacizumab (IVB) and combined treatments on biomarkers of oxidative stress such as aldehhyde dehidrogenase (ALDH), malondialdehyde (MDA) level, superoxide dismutase (SOD) activities, and vitreal vascular endothelial growth factor (VEGF) on proliferative diabetic retinopathy (DR) patients.Methods: In this single blind randomized clinical trial, 72 eyes from 69 cases of proliferative DR in Cipto Mangunkusumo Hospital between February 2011 - June 2013 were randomized into 4 groups : 1) control (n = 18); 2) LF pre-vitrectomy (n = 18); 3) IVB pre-vitrectomy (n = 18); and 4) combined IVB and LF pre-vitrectomy (n = 18). One-way ANOVA was used to compare oxidative stress parameters in the four groups.Results: There were no statistically significant differences in the average plasma ALDH activity (0.034 ± 0.02; 0.027 ± 0.02; 0.025 ± 0.02; 0.031 ± 0.11 IU/mg protein; p = 0.66), vitreal MDA level (1.661 ± 1.21; 1.557 ± 1.32; 1.717 ± 1.54; 1.501 ± 1.09 nmol/mL; p = 0.96) and SOD activity) (0.403 ± 0.50; 0.210 ± 0.18; 0.399 ± 0.49; 0.273 ± 0.32 U/mL; p = 0.38) among these four groups, respectively. However, the VEGF vitreal level (pg/mL) showed a statistically significant difference (0.356 ± 0.60; 0.393 ± 0.45; 0.150 ± 0.24; 0.069 ± 0.13; p = 0.05). The VEGF level in combination group was five times lower than the control group (p = 0.05).Conclusion: Combined treatments of DR by IVB and LF were correlated with lower vitreal MDA and plasma VEGF level, but did not have any effect on plasma ALDH and vitreal SOD in proliferative DR. Combined treatments with IVB and LF are recommended for the management of proliferative DR patients.

Abstract

This study aimed to determine the relationship between plasma lipid profile and the severity of diabetic retinopathy in type 2 diabetes patients. A cross sectional study was done in  Ophthalmologic Clinic, Cipto Mangunkusumo General Hospital, Jakarta for 52 diabetic retinopathy (DR) patients. Data collected were demographic, life style, duration of diabetes, physical and antropometric examinations, fat, fatty acid and cholesterol intake, fasting plasma glucose, A1C, total-, LDL-,HDL-cholesterol and triglyceride level, and fundus examination. Statistical analysis was done using chi-square test to see the associations between plasma lipid profile and DR in type 2 diabetes patients. Subjects comprised of 20 males and 32 females diabetes patients with mean age of 53.8 ± 5.2 years. As much as 53.8% had been diagnosed as DM for >10 years. The mean value of BMI was 24.1 ± 3.3 kg/m2 and 38.5% were classified as obese I and II. The mean value of fasting plasma glucose was 157.5 ± 71.8 mg/dL, and A1C was 9.1 ± 2.4 %. For lipid profile, 40.4% had high total cholesterol level (>240 mg/dL), 34.6% had high and very high LDL-cholesterol level (≥160 mg/dL), and 65.4% had normal HDL-cholesterol (40-60 mg/dL) and triglyceride level (<150 mg/dL). For the severity of retinopathy, 61.6% had severe non-proliferative diabetic retinopahy (NPDR) and proliferative diabetic retinopahy (PDR). In conclusion, there were no significant associations between plasma lipid profile and the severity of diabetic retinopathy.

Abstract

Background: Phacoemulsification is a common cataract operation nowadays. During phacoemulsification, variation in intraocular pressure (IOP) may occur, which might change the retinal nerve fiber layer (RNFL) thickness. This study was aimed to evaluate the change in peripapillary RNFL thickness and mean deviation (MD) of visual field after phacoemulsification in chronic primary glaucoma and non-glaucoma patients. Methods: Cohort prospective study was done on 26 patients (13 chronic glaucoma eyes and 13 non-glaucoma eyes) who underwent phacoemulsification. The changes in peripapillary RNFL thickness and MD of visual field were measured as the primary outcome. Comparison between pre- and post-surgery was analyzed with paired t-test, while unpaired t-test was used for comparison between groups.Results: There were no significant changes in RNFL thickness on both groups. Average RNFL thickness in glaucoma group before and after phacoemulsification were 94.9±20.0 μm and 99.1±21.3 μm, respectively (p>0.05). Average RNFL thickness in non-glaucoma group were 100.2±11.1 μm and 101.7±6.8 μm, respectively (p>0.05). Glaucoma patients yielded decreasing mean deviation (MD) of visual field, but it was not statistically significant (p=0.071). In contrast, the MD of visual field after surgery was significantly increased in non-glaucoma group (p=0.005).Conclusion: Phacoemulsification tended to increase peripapillary RNFL thickness in glaucoma or non-glaucoma patients. The visual field tended to decrease in glaucoma patients, but was significantly increased in non-glaucoma patients.
