Item Influence of Different Antidepressants on Ocular Surface in Patients With Major Depressive Disorder(2021) Isik Ulusoy, Selen; Ulusoy, Mahmut Oguz; 33347023Purpose Several studies have previously reported the association between dry eye and depression along with the treatment of depression. The aim of this study was to investigate the effects of different antidepressant drugs on tear parameters in patients with major depressive disorder. Methods We recruited 132 patients who were using different antidepressants and 58 healthy controls. Venlafaxine, duloxetine, escitalopram, and sertraline were used by 34, 28, 36, and 34 patients, respectively. The participants filled out and completed the Beck Depression Scale. We recorded Schirmer test, tear breakup time (TBUT) and corneal staining values of the participants. The Ocular Surface Disease Index was completed by the participants. In addition, we evaluated the tear meniscus parameters by using anterior segment optical coherence tomography. Results All conventional dry eye tests and tear meniscus parameters were significantly lesser in the depression group than in the control group (Schirmer test, 11.41 +/- 6.73 mm and 22.53 +/- 4.98 mm; TBUT, 5.29 +/- 2.92 seconds and 13.38 +/- 1.72; Corneal staining, tear meniscus area, 0.026 +/- 0.012 mm(2) and 0.11 +/- 0.025 mm(2); tear meniscus depth, 182.75 +/- 78.79 mu m and 257.48 +/- 90.1 mu m; tear meniscus height, 290.3 +/- 133.63 mu m and 459.78 +/- 180.26 mu m, in patients and controls, respectively). The tear parameters of the duloxetine group were lowest among the drug groups and Schirmer test, and TBUT of the venlafaxine group was statistically significantly different from the duloxetine group (P = 0.028 and P = 0.017, respectively). Ocular Surface Disease Index score of the depression group was significantly higher than the control group (31.12 +/- 21.15 and 17.43 +/- 11.75 in depression and control group, respectively.) Conclusions We found that the usage of selective serotonin reuptake inhibitors and serotonin noradrenaline reuptake inhibitors affects the ocular surface by a mechanism other than the anticholinergic system. Besides serotonin blockage, the noradrenaline blockade of serotonin noradrenaline reuptake inhibitors may increase the dry eye findings on the ocular surface.Item 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; 31790064Purpose: 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.Item Optical coherence tomography angiography findings of multiple sclerosis with or without optic neuritis(2020) Ulusoy, Mahmut Oguz; Horasanli, Bahriye; Isik-Ulusoy, Selen; 32048550Objective: Nowadays, retinal microvascular structures can be investigated using optical coherence tomography angiography (OCTA). We aimed to evaluate the probable vascular changes in the foveal and peripapillary regions of patients with multiple sclerosis (MS). Methods: A total of 20 patients with relapsing remitting multiple sclerosis (RRMS) and 24 healthy controls were recruited in this study. All participants' superficial and deeper retinal and peripapillary layers were evaluated using OCTA after a total ophthalmologic examination. Results: In the superficial plexus, the whole image (49.53 +/- 3.9% and 51.83 +/- 2.1%, p = 0.009), superior hemisphere (49.44 +/- 4.11% and 51.63 +/- 2.3%, p = 0.018), inferior hemisphere (49.75 +/- 3.9% and 52.03 +/- 2.2%, p = 0.012), parafoveal (51.87 +/- 3.9% and 53.08 +/- 3.46%, p = 0.048) and perifoveal (50.41 +/- 3.86% and 52.76 +/- 2.1%, p = 0.007) vascular densities were statistically significant lesser in patients with RRMS than in controls. In the optic disc OCTA parameters, the vessel density of the inferior (50.15 +/- 6.99% and 53.04 +/- 3.63% p = 0.043) and temporal sector (48.09 +/- 5.47% and 50.85 +/- 5.24%, p = 0.045) were statistically significantly lesser in patients with RRMS than in controls. Conclusion: The reductions in vessel density of the retinal or peripapillary area of patients with RRMS shown in this study should be investigated further to determine whether it is a secondary lesion to optic neuritis (ON) or a primary vasculopathic condition of MS.Item Spectral domain optical coherence tomography findings of patients with ankylosing spondylitis(2020) Kal, Ali; Ulusoy, Mahmut Oguz; Orturk, Caner; 0000-0001-7544-5790; 32533454; AAJ-4936-2021Purpose The aim of this study is to evaluate the possible effects of (ankylosing spondylitis) AS on choroidal thickness (CT) and other retinal layers using spectral domain optical coherence tomography (SD-OCT). Methods This cross-sectional study group comprised 41 AS patients and age and sex-matched 46 control subjects. None of our patients had active anterior uveitis during the measurements. We evaluated and compared CT, retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, focal loss volume (FLV) and global loss volume (GLV) of the participants. Results The CT of the patients at 1500 mu m (286.20 mu m +/- 65.81), 1000 mu m (309.55 mu m +/- 85.33) nasally to the fovea and subfoveal layer (339.93 mu m +/- 69.93) were thicker than in controls (p = 0.007,p = 0.037,p = 0.008). Except nasal layer, all RNFL layers were significantly thinner than controls (p < 0.001). GCC and macular thickness were also thinner than controls (p < 0.001). Conclusion In conclusion, present findings may suggest that the AS disease may affect the choroidal, RNFL and GCC thickness by disease's own inflammatory effect, independently from the uveitis history.Item Evaluation of the tear parameters of ovulation induction patients in a short time period with anterior segment optical coherence tomography(2020) Colak, Eser; Ulusoy, Mahmut Oguz; Ceran, Mehmet Ufuk; Tasdemir, Umit; Kal, Ali; Ozcimen, Emel Ebru; 33470279Purpose: The effects of sex steroid hormones on tearparameters are known. Theaim of this studywas to examine the effects on tear parameters during exposure to high-dose sex steroids in a short period of time. Methods: Forty patients who were admitted to the infertility clinic of our hospital and planned to undergo ovulation induction with exogenous gonadotropins were included in our study. Prior tothe initiation of ovulation induction, the basal levels of estradiol were measured on day 3 of the menstrual cycle and ophthalmologic examinations were performed by the ophthalmology department of our hospital. The estradiol levels were-measured on the day ofovulation induction usinghuman chorionic gonadotropin and compared with basal estradiol; eye examinations were also repeated. Result: Forty women with reproductive period and average age of 33.3 +/- 4.2 years were included in this study. Basal levels of estradiol were significantly (p<0.001) higher after ovulation induction than before induction. The scores in the break-up timeand after induction were 6.2 +/- 2.8 sn and 8.4 +/- 1.4 sn, respectively. The values of Schirmer's test were 14.3 +/- 7.1 mm and 20.6 +/- 6.2 mm before and after induction, respectively. Both values were significantly higher after ovulation induction (p<0.001; p=0.001, respectively). Conclusion: We observed improvemet in tear function tests following the use of estradiol even for a limited time .The use of estradiol during menopause may improve dry eye symptoms in patients.Item Retinal vascular density evaluation of migraine patients with and without aura and association with white matter hyperintensities(2019) Ulusoy, Mahmut Oguz; Horosanli, Bahriye; Kal, Ali; 30762208Underlying pathophysiological mechanism of migraine is not all clear; however, recent reports suggested that neurovascular system is involved. We aimed to evaluate the retinal vessel densities of migraine patients with and without aura and the associations with white matter hyperintensities (WMH), using optical coherence tomography angiography (OCTA). We recruited 28 migraine with aura (MWA) patients, 26 migraine without aura (MWO) and age and sex-matched 34 healthy controls in our study. All participants were evaluated with optical coherence tomography (OCT) and OCTA for optic nerve parameters and retinal vessel densities with RTVue XR AVANTI. On macular OCTA, superficial and deeper retinal foveal vessel density (VD) were significantly lesser in MWA and MWO than controls. On optic nerve OCTA, whole optic disc, peripapillary, superior hemisphere, superior layer and temporal layer VD were significantly lesser in MWA and MWO. In group of MWA with the WMH, deeper foveal VD and superior hemisphere VD, average RNFL, superior hemisphere and superior layer were significantly lesser and also foveal avascular zone was significantly larger than the group of without WMH. Alterations of VD in patients with migraine are showed in our study. In addition, in group of MWA these alterations have associations with WMH. Supporting these findings with further reports can be useful to understand the pathophysiology of this disease.Item 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; 31528761Purpose: 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.

We aimed to evaluate the optical coherence tomography angiography (OCTA) findings of Behcet uveitis (BU) patients.MethodsWe evaluated 32 eyes of 16 patients with BU and 30 eyes of 15 healthy controls. Superficial capillary plexus (SCP) and deeper capillary plexuses (DCP) were evaluated using OCTA RTVue XR AVANTI.ResultsOn SCP, nonperfusion/hypoperfusion areas (NPA) were seen in 10 eyes, perifoveal capillary arcade disruption (PCAD) was seen in 10 eyes, capillary network disorganization (CND) was seen in 7 eyes and intraretinal cystoid spaces (ICS) were seen in 2 eyes. On DCP, NPA were seen in 13 eyes, PCAD was seen in 11 eyes, CND was seen in 7 eyes and ICS were seen in 4 eyes.ConclusionWe showed that DCP were affected more than SCP in these patients. In addition, capillary vessel density of BU group was significantly lower than control group.Item How Important Is the Etiology in the Treatment of Epiphora?(2016) Ulusoy, Mahmut Oguz; Kivanc, Sertac Argun; Atakan, Mehmet; Akova-Budak, Berna; 27595013Purpose. 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.Item Evaluation of the acute effect of haemodialysis on retina and optic nerve with optical coherence tomography(2016) Emre, Sinan; Ozturkeri, Anil; Ulusoy, Mahmut Oguz; Cankurtaran, Cem; 28003781; T-5643-2019Purpose: The primary objective of haemodialysis (HD) was to correct the composition and volume of body fluids. The aim of this study was to evaluate the acute effect of HD on mean arterial pressure changes and on retina and optic nerve with optical coherence tomography (OCT). Methods: Fifty-three eyes of 28 patients were enrolled in this study. The patients' retinal and RNFL thicknesses were measured by OCT and mean arterial pressure alterations were recorded before and immediately after HD session. Results: The results show that while there was a reduction at central foveal thickness and ganglion cell layer thickness, central sub-field and RNFL thickness were increased with HD session. But none of them were statistically significant (p = 0.320, p = 0.792, p = 0.744, p = 0.390). The mean arterial pressure of the patients decreased significantly (p < 0.05) but it was not correlated with retinal and RNFL values. Conclusion: The changes in retinal and RNFL findings were not significant. But these alterations may effect the long term follow-up of the patients with retinal and optic nerve disease. Therefore it is important to pay attention HD session time for these patients' measurements.
