Öğe Comparison of Anterior Segment Measurements in Obese Children and Healthy Control Group(Duzce Univ, Fac Medicine, 2023) Eski, Mehmet Tahir; Teberik, Kuddusi; Sezer, Taha; Arslanoglu, IlknurOphthalmology, Objective: To evaluate anterior segment parameters in obese children. Methods: Fifty-five obese and 30 control group children subjects participated. All participants and the control group were examined and anthropometric measurements were made. The measurements of fasting blood glucose (FBG), systolic blood pressure (SBP) triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), and insulin values were performed. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Each participant underwent a detailed ophthalmic examination and intraocular pressure (IOP), central corneal thickness (CCT), anterior chamber depth (ACD) and lens thickness (LT) were measured. Results: The gender distribution of the groups was similar (p=0.893). The mean of CCT and LT were significantly higher in the obese group (572.9 & PLUSMN; 14.5 vs. 559.5 & PLUSMN; 10.1 & mu;m, p=0.001; 3.6 & PLUSMN; 0.14 vs. 3.48 & PLUSMN; 0.25 mm, p=0.007). No significant difference was found between the obese and control groups in terms of other parameters. Body mass index (BMI) and waist circumference (WC) had a significant negative correlation with LT control groups. The obese group showed a significant positive correlation between IOP and TG (r=0.276, p=0.042), and a significant negative correlation with HDL-C (r=-0.273, p=0.043). In the control group, there was a significant positive correlation between IOP and BMI (r=0.389, p=0.034), WC (r=0.497, p=0.005), HOMA-IR (r=0.384, p=0.036), Insulin (r=0.407, p=0.026), and a significant negative correlation with TC (r=-0.511, p=0.004). A significantly positive correlation between ACD and LDL-C (r=0.371, p=0.043) and a significantly negative correlation between HOMA-IR in the control group were detected (r=-0.682, p=0.000). Conclusions: The obese group had higher CCT and LT than the control groups.Öğe Comparison of the effects of 3 different anti-VEGF drugs on cornea thickness, lens thickness and anterior chamber depth: Case-Control Study(2023) Eski, Mehmet Tahir; Teberik, Kuddusi; Sezer, TahaTo compare the long-term effects of 3 different anti-VEGF molecules on the lens, cornea and anterior chamber in phakic patients who have received consecutive intravitreal injections. 157 patients who did not have corneal pathology but were treated with 1.25mg/0.05ml intravitreal bevacizumab, 0.5mg/0.5ml ranibizumab or 2mg/0.05ml aflibercept injections due to diabetic macular edema were retrospectively analyzed in our clinic. Patients who received three consecutive monthly injections were included to the study. Corneal thickness, lens thickness and anterior chamber depth measurements which were taken before the injections, 1 month after the first injection, 1 month after the second injection, and 1 month after the third injection were used in the study. There was no statistical difference between the bevacizumab, ranibizumab, aflibercept and control group in terms of preoperative specifications such as number of patients, gender and age average. A statistically significant difference was found between the 4 anterior chamber depth measurements in the control group, Ranibizumab drug group, and Bevacizumab and Aflibercept drug groups (p<0.001, p=0.026; p=0.07, p<0.001, respectively). Anterior chamber depth of the Ranibizumab and Bevacizumab patients decreased in the first month and increased in the second and third months. However, anterior chamber depth of the Aflibercept patients increased over time. As a result of our study; we concluded that three different anti- VEGF drug molecules have an effect on the anterior camera.Öğe Evaluation of peripapillary choroidal vascularity index in young smokers(Taylor & Francis Ltd, 2023) Eski, Mehmet Tahir; Sezer, Taha; Bayraktar, Havvanur; Altikardesler, EmirPurpose: This retrospective study aimed to compare the peripapillary choroidal vascularity index (CVI) between young smokers who smoked less than 5 packs/year and non-smokers. Methods: The study included 52 smokers and 67 non-smokers, and comprehensive eye examinations were performed on all participants. Axial lengths (AL) were measured, and peripapillary enhanced depth imaging optical coherence tomography (EDI-OCT) images were obtained and evaluated using the Open Source ImageJ software. The CVI, total choroidal area ( TCA), luminal area (LA), stromal area (SA), and retinal nerve fibre layer (RNFL) quadrants were compared between the two groups. Results: The mean age of the smokers was 23.76 +/- 1.84 years, and for non-smokers, it was 23.98 +/- 2.18 years. The mean peripapillary CVI for smokers was 0.65 +/- 0.08, and for non-smokers, it was 0.67 +/- 0.03. No statistically significant difference in CVI was observed between the two groups. However, statistically significant differences were found in the temporal inferior (TI), temporal superior (TS), nasal inferior (NI), and nasal superior (NS) quadrants of the RNFL between the two groups (p < 0.05). There was no correlation between the number of packs/year and CVI values in the smoking group (r = 0.031, p = 0.826). Conclusion: The study revealed no significant difference in CVI among young smokers who smoked less than 5 packs/year compared to non-smokers. However, there was a statistically significant decrease in the TI, TS, NI, and NS quadrants of the RNFL in early-age smokers.Öğe Oftalmopatisiz Hipertiroidik Hastalarda Optik Cohorens Tomografi Bulguları(2023) Eski, Mehmet Tahir; Teberik, Kuddusi; Sezer, Taha; Önmez, AttilaAmaç: Bu çalışmada, hipertiroidi tanısı olan ve oftalmopati gelişmemiş hastalardaki koroid, retina ve peripapiller sinir lifi tabakasının kalınlığını ötiroid hasta grubuyla karşılaştırmak amaçlanmıştır.

Three groups, a control group and two study groups (patients examined 14 days after BTA administration-Study Group 1, and patients examined 28 days after BTA administration-Study Group 2) were evaluated. Dilated fundus examinations were performed following detailed ophthalmological examinations and VEP tests. Keypoint (Dantec, Denmark) and ISCEV criteria were adopted for pattern VEP (PVEP) recording. BTA was applied in the form of local injections at a total 15-30 units, at 2.5-5 units per injection.ResultsA mean 19.4 +/- 3.2 units of BTA was used for each eye. N70 (ms), P100 (ms), and P100 (uV) values were statistically significantly lower in both study groups following drug administrations compared to the control group (p < 0.001 for all). Significant positive correlation was observed between increased P100 amplitudes and age in the control group (p = 0.008, r = 0.200). Significant negative correlation was observed between the BTA units used and decreased P100 amplitudes in both study groups 1 and 2 following drug administrations (p = 0.017, r = - 0.180 and p = 0.043, r = - 0.153, respectively).ConclusionVEP may be an important method in the diagnosis and follow-up of blepharospasm and in determining the success of drug administration and additional therapeutic requirements.
