Item Investigation of ARHGEF12 Single Nucleotide Polymorphism in Hypercholesterolemia and Primary Open Angle Glaucoma(2020) Yaman, Derya; Takmaz, Tamer; Dincer, Selin Akad; Sahin, Feride Iffet; 0000-0001-7308-9673; AAK-2511-2021; AAC-7232-2020Objective:To investigate the effect of single nucleotide polymorphism rs58073046 A>G within the ARHGEF12 gene in patients with hypercholesterolemia and primary open angle glaucoma. Methods: Blood samples of 20 patients with high serum cholesterol and primary open angle glaucoma (Group 1), 20 sex and age matched healthy subjects (Group 2) as controls were enrolled to the study. The ARHGEF12 gene polymorphism was determined by polymerase chain reaction and DNA sequence analysis. The data were assessed by descriptive statics and Fisher exact x(2) test. Results: The homozygous wild type genotype (AA) was identified in 95 % of Group 1 versus 100 % of Group 2. The homozygous mutant genotype (GG), presented the highest prevelance in Group 1 (5%), although the difference was not statistically significant between groups (p=0.5). Conclusion: This is the first study to identify the role of ARHGEF12 gene variant in the risk of hypercholesterolemia and POAG. Our results showed that there is no association between rs58073046 A>G polymorphism and disease development.Item Visual Outcomes at 12 Months in Patients Following Implantation of a Diffractive Multifocal Intraocular(2015) Baykara, Mehmet; Akova, Yonca Aydin; Arslan, Osman Sevki; Cinhuseyinoglu, Necdet; Takmaz, Tamer; Gucukoglu, Ahmet; Usta, Yildirim Beyazit; 25825014Introduction: The aim of this study was to assess distance, intermediate, and near visual acuity, contrast sensitivity, and patient satisfaction outcomes of a multifocal intraocular lens (IOL). Methods: This multicenter, prospective clinical study was conducted at seven study sites in Turkey. Patients who underwent bilateral cataract removal and implantation of a diffractive, acrylic, hydrophobic, multifocal IOL (Acriva UD Reviol MFB 625; VSY Biotechnology, Istanbul, Turkey) were included. The uncorrected and best corrected distance visual acuities (UCDVA and BCDVA), uncorrected and best corrected intermediate visual acuities (UCIVA and BCIVA), and uncorrected and best corrected near visual acuities (UCNVA and BCNVA) were measured preoperatively and at postoperative 1, 6, and 12 months. Distance and near visual acuity scores (VAS) contrast sensitivities were measured at these time points. Quality of life was evaluated by visual function-14 (VF-14) questionnaire. Results: Two hundred eyes of 100 patients were included. Monocular and binocular visual acuities at all distances showed improvement at postoperative 12 months compared to preoperative measurements (P < 0.001). Monocular and binocular UCIVA and binocular BCIVA at postoperative 12 months were significantly improved compared to measurements at 1 month (P < 0.001). Binocular contrast sensitivity at distance showed significant improvement from postoperative 1 month to postoperative 12 months, except for 3 cycles per degree (cpd; without glare) and 18 cpd (with glare). VAS improved from 75.96 at postoperative 1 month to 76.85 at postoperative 12 months. VF-14 score was 98.2 +/- 4.6. Conclusion: The Acriva UD Reviol MFB 625 appears to provide a good level of distance and near visual acuity, quality of life, and patient satisfaction. Further studies with longer follow-up will provide valuable insight into the long-term stability of these visual outcomes.
