Purpose: The aim of this study is to assess the awareness of the diabetic retinopathy and the level of the diabetic retinopathy in the diabetic patients, which consulted to the state hospitals in Turkey. Methods: A total of 1071 patients, admitted to 8 different state hospitals' ophthalmology clinics around the country, were included to this cross sectional multicentred study. All diabetic patients were asked to respond specifically prepared questionnaire including diabetic retinopathy and diabetes mellitus and underwent fundus examination to assess the diabetic retinopathy level. Results: The mean age of the study population was 57.5 years and the 57.4 % of the patients were women. 34.7% of the patients' were responded "NO" to the question of "Are you aware of the eye complications of diabetes mellitus?". The study also showed that 200 of 699 patients (28.6%) who aware of the diabetic retinopathy, despite having this information do not have regular eye examination for the diabetic retinopathy. It was seen that even 40.62% (26/64) of the college graduates don't go regular checks. The majority of the aware patients (40.5 %) pointed out that they took information from internal medicine or endocrinologists and the 28.1% of the patients were informed from elsewhere (family, neighbor, TV, etc.). Conclusion: One third of the subjects monitored were not aware of diabetic retinopathy. It is noteworthy to emphasize the importance of the routine eye examination for preventing vision loss, regardless of the educational level. The warning of the physicians through written and visual media is thought to be effective in preventing irreversible condition of this disease.

Evaluation of dry eye disease in newly diagnosed anxiety and depression patients using anterior segment optical coherence tomography
(2019) Ulusoy, Mahmut Oguz; Isik-Ulusoy, Selen; Kivanc, Sertac Argun; 31417939
Background We aimed to evaluate dry eye diseases (DED) in patients with newly diagnosed depression and anxiety patients. Methods Forty newly diagnosed depression, 35 anxiety patients, and 37 controls without any history of taking psychiatric drugs (or before the beginning of psychiatric medication) and topical ophthalmic drop use, were included in the study. All depression and anxiety diagnoses were performed by an experienced psychiatrist. Beck depression and anxiety tests were used to measure disease severity. Tear film break up time (TBUT), Schirmer's test, Oxford scores and ocular surface disease index (OSDI) were admiinistered to participants. Anterior segment optical coherence tomography was used to measure tear meniscus heights (TMH), tear meniscus depths (TMD) and tear meniscus areas (TMA). Results In anxiety and depression groups, Schirmer's test (mm) (7.24 +/- 6.02, 6.58 +/- 4.9 and 18.79 +/- 4.9 respectively, p < 0.05) and TBUT (s) (5.62 +/- 3.1, 5.6 +/- 3.5 and 13.37 +/- 1.7 respectively, p < 0.05) were significantly lower than control group. In addition, OSDI and Oxford scores were significantly higher than controls. OSDI scores were 28.01 +/- 19, 30.43 +/- 18.49, 14.38 +/- 8.14 respectively (p = 0.002) and Oxford scores were 1.9 +/- 0.7, 2.1 +/- 0.6 and 0.7 +/- 0.4 respectively (p = 0.001). TMD, TMH and TMA values were significantly lower in anxiety and depression groups compared with control groups. Correlations between disease inventory scores and dry eye tests were detected. Conclusions This study showed a relation between DED and newly diagnosed anxiety and depression patients with no history of psychiatric drug use. The presence of correlation between dry eye tests and disease inventory scores strengthens this association. This is an important knowledge that need to be evaluated in these patients before starting psychiatric medication.
Evaluation of Iridocorneal Angle, Choroidal Thickness, and Retinal Nerve Fiber Layer Thickness in Children With a History of Retinopathy of Prematurity
(2020) Ulusoy, Mahmut Oguz; Kivanc, Sertac Argun; Kal, Ali; 31790064
Purpose: Retinopathy of prematurity (ROP) is proliferative retinopathy affecting premature infants associated with abnormal maturation of the retinal vasculature. We sought to evaluate iridocorneal angle, choroidal thickness, and retinal nerve fiber layer thickness (RNFLT) of the children that have a history of ROP using spectral-domain optical coherence tomography. Patients and Methods: Fifty eyes of 28 children with a history of ROP and 46 eyes of 23 healthy school-aged children were included in this study. RNFLT, choroidal thickness, and iridocorneal angle parameters [trabecular iris angle, angle opening distance (AOD500), and trabecular iris space area (TISA500) 500 mu m from the scleral spur] were evaluated using spectral-domain optical coherence tomography. Student t test was used to compare the mean of the parameters. Correlations between the variables were investigated based on the Pearson or Spearman correlation coefficient. Results: Subfoveal (ROP: 253.98 +/- 42.5; control: 286.2 +/- 71.9; P=0.045), 500 mu m (ROP: 242.04 +/- 41.8; control: 276.7 +/- 45.3; P=0.003), 1000 mu m (ROP: 237 +/- 39.7; control: 270.15 +/- 55.93; P=0.007), and 1500 mu m (ROP: 224.16 +/- 37.5; control: 259.75 +/- 55.2; P=0.003) temporal choroidal thicknesses were significantly thinner in ROP history children. None of the RNFLT parameters and ganglion cell complex thickness were different between groups. Iridocorneal angle parameters were significantly lower in children with ROP history. (trabecular iris angle: ROP=31.35 +/- 3.9 degrees, control=35.4 +/- 4.5 degrees, P<0.001; TISA500: ROP=0.167 +/- 0.05 mm(2), control=0.21 +/- 0.05 mm(2), P=0.003; AOD500: ROP=480.96 +/- 160.4 mu m, control=542.95 +/- 161.2 mu m, P=0.035). Conclusions: ROP is associated with differences in the iridocorneal angle. Possible iridocorneal angle pathology should be a consideration in children with a history of ROP.
How Important Is the Etiology in the Treatment of Epiphora?
(2016) Ulusoy, Mahmut Oguz; Kivanc, Sertac Argun; Atakan, Mehmet; Akova-Budak, Berna; 27595013
Purpose. There are several etiological factors that cause epiphora, and treatment differs according to the cause. We aimed to evaluate the etiology of epiphora and the treatment modalities of the affected patients. Materials and Methods. Data of patients who were referred to ophthalmology clinics for epiphora were retrospectively analyzed. All patients were evaluated for epiphora etiology, treatment modalities, and duration of complaints, after complete ophthalmologic examination. Results. This study consisted of 163 patients with a mean age of 64.61 +/- 16.52 years (range 1-92 years). Lacrimal system disease (48.4% [79/163]) was the most common cause, followed by ocular surface disease (dry eye/blepharitis) (38.7% [ 63/163]). Among the patients included in this study, 69% (113/163) did not receive any treatment, whereas only 1.8% (3/163) were treated surgically. About 4.3% of the patients (7/163) had a complaint for more than 5 years (p = 0.012) and six of these had chronic dacryocystitis and one had ectropion. Conclusion. Epiphora not only has a negative impact on patients' comfort, but also puts them at risk for probable intraocular operations in the future. Therefore, the wide range of its etiology must be taken into consideration and adequate etiology-specific treatment options must be applied.
Prevalence and associated factors of external punctal stenosis among elderly patients in Turkey
(2017) Ulusoy, Mahmut Oguz; Atakan, Mehmet; Kivanc, Sertac Argun; 29160539
Purpose: To estimate the prevalence of external punctal stenosis (EPS) in the elderly population and investigate associated factors. Methods: A total of 278 patients >= 65 years of age were evaluated for evidence of EPS from January to July 2016. Associated systemic, ocular, demographic, and lifestyle factors were investigated. Multiple logistic regression analyses were applied to evaluate the factors related to having EPS. P values <0.05 were considered statistically significant. Results: The prevalence of EPS in this study population was 63.3%, with a mean age of 70.67 +/- 7.85 (65-92 years). The ocular factor that was most commonly related to EPS was chronic blepharitis (48.9%). EPS was also associated with taking glaucoma medications (95% CI, 0.08-0.96, p=0.043), smoking history (95% CI, 0.13-0.84, p=0.021), ectropion (95% CI, 0.004-0.26, p=0.001), complaints of tearing (95% CI, 1.11-3.52, p=0.02), and outdoor occupational activity (95% CI, 3.42-9.97, p<0.05). Conclusions: EPS is more common in elderly patients than in the general population. Outdoor occupational activity, taking antiglaucomatous medications, ectropion, and smoking are significantly associated with EPS. In addition, surgical treatment decisions should be made after complete evaluation and interviewing the patients.
Spectral domain optical coherence tomography findings in Turkish sickle-cell disease and beta thalassemia major patients
(2019) Ulusoy, Mahmut Oguz; Turk, Hakan; Kivanc, Sertac Argun; 31528761
Purpose: To assess probable structural changes using spectral domain optical coherence tomography (SD-OCT) on sickle-cell disease (SCD) and beta thalassemia major (B-TM) patients, without any retinal abnormalities. Methods: This cross-sectional study included 32 B-TM, 34 SCD patients, and 44 healthy controls. One of the eyes of all participants was evaluated for SD-OCT and choroidal thickness, retinal nerve fiber layer (RNFL) thickness, central macular thickness (CMT), ganglion cell complex (GCC). Results: Age, gender, and intraocular pressure (IOP) were not statistically different between the three groups. Hemoglobin (Hgb), hematocrite (Htc), and ferritin levels were not statistically different between the SCD and B-TM groups. Choroidal thickness at the subfoveal region was statistically higher in the control group (353.79 +/- 71.93) than in the B-TM (317.41 +/- 53.44) and SCD (283.21 +/- 63.27) groups. In addition, it was statistically higher in the B-TM group than the SCD group (P = 0.05). CMT did not differ among the three groups, average RNFL was only significantly thinner in SCD than in controls, and GCC thickness was significantly thinner in SCD than in controls and B-TM. Conclusion: In both diseases, we can show early structural changes even if proliferative or non-proliferative retinopathy or other ocular manifestations were not developed yet.
