The impact of primary open-angle glaucoma: Quality of life in Indian patients.

ABSTRACT: Glaucoma significantly affects the quality of life (QoL) of a patient. Despite the huge number of glaucoma patients in India, not many, QoL studies have been carried out. The purpose of the present study was to evaluate the QoL in Indian patients with varying severity of glaucoma.This was a hospital-based, cross-sectional, analytical study of 180 patients. The QoL was assessed using orally administered QoL instruments comprising of two glaucoma-specific instruments; Glaucoma Quality of Life-15 (GQL-15) and Viswanathan 10 instrument, and 1 vision-specific instrument; National Eye Institute Visual Function Questionnaire-25 (NEIVFQ25).Using NEIVFQ25, the difference between mean QoL scores among cases (88.34 ± 4.53) and controls (95.32 ± 5.76) was statistically significant. In GQL-15, there was a statistically significant difference between mean scores of cases (22.58 ± 5.23) and controls (16.52 ± 1.24). The difference in mean scores with Viswanathan 10 instrument in cases (7.92 ± 0.54) and controls (9.475 ± 0.505) was also statistically significant. QoL scores also showed moderate correlation with mean deviation, pattern standard deviation, and vertical cup-disc ratio.In our study, all the three instruments showed decrease in QoL in glaucoma patients compared to controls. With the increase in severity of glaucoma, corresponding decrease in QoL was observed. It is important for ophthalmologists to understand about the QoL in glaucoma patients so as to have a more holistic approach to patients and for effective delivery of treatment.

Project description:PURPOSE: Glaucoma is a heterogeneous group of optic neuropathies with a complex genetic basis. To date, only the following four genes have been identified: viz. myocilin (MYOC), optineurin (OPTN), WD repeat domain 36 (WDR36), and neurotrophin 4 (NTF4). However, there are conflicting reports regarding the involvement of WDR36 in the pathogenesis of primary open-angle glaucoma (POAG). In the Asian population, mutations in WDR36 appear to play a minor role in POAG pathogenesis but polymorphic variants have been found to be associated with POAG, especially in patients with high tension glaucoma (HTG). The purpose of this study is to determine the role of WDR36 in East Indian POAG patients. To date, no other studies have yet examined this role. METHODS: Ten single nucleotide polymorphisms (SNPs; rs1971050, rs1993465, rs13153937, rs10038177, rs11241095, rs10043631, rs10038058, rs10491424, rs17553936, and rs13186912) spanning almost the entire WDR36 gene were selected and their association with eastern Indian POAG patients was evaluated. Our study pool consisted of 323 POAG patients. Of these 116 were patients who had HTG with intraocular perssure (IOP) >21mmHg and 207 were found to be non-HTG patients (presenting IOP<21mmHg). The study also included 303 participants as controls. The polymorphisms were genotyped in both the patients and the controls using the PCR-RFLP method. Moreover, the SNP that showed significant association was validated by DNA sequencing. The haplotypes were obtained using Haploview 4.1 software. The allele and haplotype frequencies were compared between the patient group and the control group using Pearson's ?(2) test. RESULTS: First, we genotyped the selected SNPs in the 323 POAG patients and 119 of the participants in the control group, in which only rs10038177 (c.710+30C>T) was found to be strongly associated with the HTG cases (OR=2.186; 95% CI=1.458-3.277; p=1.4×10(-4)). To increase the significance of the study, the SNP was genotyped in an additional 184 of the participants in the control group and it was observed that the SNP retained the association (OR=1.216; 95% CI=1.064-2.306; p=0.002). However, no haplotype was found to have any sustainable association with POAG. Based on the LD pattern and location of rs10038177, exon 5 of WDR36 was sequenced but no suspected disease-causing variant was detected. CONCLUSIONS: Our study suggests a possible association between WDR36 SNP in a cohort of eastern Indian POAG patients who also have high intraocular pressure (IOP). This study needs to be further validated in a larger patient cohort.
