Publication Metadata only Orbital myositis associated with celiac disease(SPRINGER, 2014) ÇERMAN, EREN; Cerman, Eren; Esen, Fehim; Eraslan, Muhsin; Kazokoglu, HalukA 26-year-old female patient presented with redness, lid edema on the right eye and diplopia on left gaze. There was a minimal limitation of adduction of the right eye, accompanied with pain and diplopia. Orbital magnetic resonance imaging confirmed the diagnosis of orbital myositis. Anti-endomysial immunoglobulin (Ig) A, anti-endomysial IgG, anti-gliadin IgA and anti-tissue transglutaminase IgG antibodies were positive, while other tests for autoimmune diseases were unremarkable. The patient stated that her diarrhea had been relieved by a gluten-free diet. Methylprednisolone therapy (1 mg/kg) was started and on her next visit her complaints were relieved. Later, methotrexate (15 mg/week) was added to the therapy as the patient became steroid-dependent, and she has been attack-free for the last 3 months under methotrexate and low-dose methylprednisolone (4 mg/day) treatment. Associations between orbital myositis and various autoimmune diseases have previously been reported. We report here the first case of associated orbital myositis and celiac disease.Publication Metadata only Increased serum sialic acid in diabetic retinopathy of type 1 diabetes(2013) YAVUZ, DİLEK; Eraslan M., Yenice O., Kazokoglu H., Yavuz D.G., Cerman E., Celiker H.AIM: To investigate the potential association between serum sialic acid and diabetic retinopathy and its several grades. METHODS: We studied the level of serum sialic acid in 70 patients. Thirty control vs 40 type 1 diabetics and with different levels of diabetic retinopathy as well. RESULTS: We found higher levels of serum sialic acid level in diabetics compared to control subjects (95.95±9.5 vs 45.05±19.91 mmoL/L, P=0.0001). We also observed a progressive rise in its concentration as the level of diabetic retinopathy increased (P<0.05) but the correlation was weak. Serum sialic acid level correlated positively with blood glucose level (r=0.67, P=0.0001). CONCLUSION: Increase in serum sialic acid levels seems to be related to the stage of the retinopathy and may help us to determine the extent of retinopathy in type 1 diabetic patients. But we think that we need more detailed studies to get a more precise conclusion.Publication Metadata only Choroidal varix elevates macula following Valsalva manoeuvre(BMJ PUBLISHING GROUP, 2014) ÇERMAN, EREN; Cerman, Eren; Eraslan, Muhsin; Dericioglu, Volkan; Sahin, Ozlem; Cekic, Osman; Mahmutyazicioglu, KamranPublication Metadata only Topiramate and accommodation: Does topiramate cause accommodative dysfunction?(CANADIAN OPHTHAL SOC, 2017) ÇERMAN, EREN; Cerman, Eren; Turhan, Semra Akkaya; Eraslan, Muhsin; Koytak, Pinar Kahraman; Kilinc, Ozden; Tanridag, TlinObjective: To investigate the accommodation function in topiramate users. Design:Case-control clinical study. Participants:The participants included 16 controls and 22 patients using 100 mg/kg topiramate who were diagnosed with migraine according to the International Classification of Headache Disorders, second edition criteria. Methods:One-minute dynamic measurements of refraction with accommodation stimuli of 0 D, 2 D, 2.5 D, 3 D, 4 D, and 5 D were obtained using the open field refractometer WAM-5500 in. Results:In most of the accommodation stimuli ranges (0 D, 2.5 D, 3 D, and 5 D), topiramate users had a significantly higher accommodative lag compared with controls (p=0.028, p =0.014, p=0.011, and p=0.011, respectively). The most important causes of accommodative lag were found to be accommodation stimulus and inclusion in the topiramate group (p<0.001, R-2=0.32, 95% CI 0.22-0.37 and 0.42-0.91, respectively). Multivariate linear regression analysis revealed that the 2 most important predictors of accommodative lag were accommodation stimulus and age (p<0.001, r=0.51, 95% CI 0.31-0.32 and 0.67-0.69, respectively) CONCLUSIONS: Even after adjustment for age, accommodative lag is greater across several accommodative stimulus levels in patients using topiramate, which may be related to visual symptoms in topiramate users.Publication Metadata only The relationship of age when motor alignment is achieved and the subsequent development of stereopsis in infantile esotropia(MOSBY-ELSEVIER, 2014) ÇERMAN, EREN; Cerman, Eren; Eraslan, Muhsin; Ogut, Mehdi S.PURPOSE To determine the oldest age beyond which the chance of developing stereopsis is not possible even with excellent motor alignment in patients with infantile esotropia. METHODS The medical records of children with infantile esotropia who underwent a single operation and had alignment within 10(Delta) of orthotropia at all follow-up examinations were retrospectively reviewed. Patients were assessed for stereopsis after the age of 48 months. RESULTS A total of 38 children were included. There was a statistically significant inverse correlation between age at surgery and final stereopsis (r = 0.494, P = 0.002). There was a significant difference at mean age at surgery between patients having stereopsis better than 1000 arcsec and those having no stereopsis (P = 0.002). Post hoc power analysis revealed a value of 85%. Receiver operating characteristic curve analysis revealed that the optimum cut-off value of the age at surgery for predicting stereopsis was 16 months (Youden index = 0.474; area under ROC curve, 0.784; 95% CI: 0.62-0.90; P = 0.0002). CONCLUSIONS Surgery for infantile esotropia is most likely to result in measureable stereopsis if patient age at alignment is not more than 16 months.Publication Metadata only Screening for Retinopathy of Prematurity in a Tertiary Ophthalmology Department in Turkey: Incidence, Outcomes, and Risk Factors(SLACK INC, 2014) ÇERMAN, EREN; Cerman, Eren; Balci, Sevcan Yildiz; Yenice, Ozlem Sahin; Kazokoglu, Haluk; Celiker, Hande; Eraslan, MuhsinBACKGROUND AND OBJECTIVE: The aim of this study is to determine the incidence of retinopathy of prematurity (ROP), the number of preterm infants requiring treatment for ROP, and the factors influencing the development of ROP requiring treatment in a Turkish population. PATIENTS AND METHODS: Data on 1,252 infants who were screened for ROP in an ophthalmology department were retrospectively reviewed. Infants with a gestational age (GA) of no more than 28 weeks (n = 157) were designated group 1, those between 29 and 32 weeks (n = 572) were assigned to group 2, and those between 33 and 37 weeks (n = 523) were assigned to group 3. RESULTS: In group 1, ROP was detected in 70.0% of infants, 17.8% of whom required therapy. In group 2, ROP was detected in 41.4%, and 4.0% of those required therapy. In group 3, 18.1% were diagnosed with ROP, with 0.8% requiring treatment. CONCLUSION: Retinopathy of prematurity occurs, even among more mature infants, at a frequency that merits astute screening within parameters that reflect socioeconomic differences that appear to have an effect on the incidence.Publication Metadata only Authors' response: evaluation of choroidal thickness among patients with oculocutaneous albinism(2014) ÇERMAN, EREN; Karabas, Levent; Esen, Fehim; Celiker, Hande; Elcioglu, Nursel; Cerman, Eren; Eraslan, Muhsin; Kazokoglu, Haluk; Sahin, OzlemPublication Metadata only Diurnal Spikes of Intraocular Pressure in Uveitic Glaucoma: A 24-hour Intraocular Pressure Monitoring Study(TAYLOR & FRANCIS INC, 2020) ÇERMAN, EREN; Esen, Fehim; Eraslan, Muhsin; Cerman, Eren; Celiker, Hande; Kazokoglu, HalukPurpose The aim of this study was to document diurnal changes in intraocular pressure (IOP) in uveitic glaucoma (UG) and compare it with primary open angle glaucoma (POAG) patients. Methods Eight patients with UG and seven patients with POAG were included in this study. The patients were matched for age, gender, and glaucoma medications. None of the patients experienced angle closure, uveitis attack, and ocular surgery, and were not under steroid or immunomodulatory therapy within the last three months. The 24-hour IOP fluctuations were recorded with the help of a contact lens sensor (Sensimed Triggerfish (R), Switzerland). The diurnal IOP fluctuations were modeled with best-fit lines and statistical comparisons between the longitudinal responses of the two groups were determined with nonlinear regression. Results The comparison of mean 24-hour contact lens sensor (CLS) amplitudes revealed a significant difference between the fluctuation levels of UG and POAG groups (213 +/- 160 millivolt equivalents (mVeq) vs. 162 +/- 168 mVeq, respectivelyp= .003). The top level of the best-fit curves was significantly higher in the UG group (266 +/- 143 mVeq) compared to the POAG group (159 +/- 162 mVeq,p< .001). Both curves had their top levels between 5:00 PM and 8:00 AM. The longitudinal regression analysis revealed that the amplitudes of the 24-hour fluctuation waves were significantly different (p= .041). Conclusions This study demonstrated for the first time that the diurnal variation in IOP was significantly higher in UG patients. This difference was also more distinct between 5:00 PM and 8:00 AM clock-hours. The uveitis and glaucoma specialists should consider this potential for higher IOP fluctuations, while tailoring the glaucoma treatment in uveitic patients.Publication Metadata only Neurodegeneration in ocular and central nervous systems: optical coherence tomography study in normal-tension glaucoma and Alzheimer disease(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2015) ÇERMAN, EREN; Eraslan, Muhsin; Cerman, Eren; Cekic, Osman; Balci, Sevcan; Dericioglu, Volkan; Sahin, Ozlem; Suer, Devran; Chabou, Biman; Tuncer Elmaci, Emine NeseBackground/aim: To evaluate, in vivo, the optical coherence tomography (OCT) of the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) in patients with normal-tension glaucoma (NTG) and those with Alzheimer disease (AD) in comparison with healthy subjects. Materials and methods: This cross-sectional study included 18 patients with NTG, 20 with AD, and 20 control subjects. An ophthalmologic examination and OCT scans of both eyes were performed in all patients. Results: There was a significant reduction in peripapillary RNFL thickness and macular GCC thickness and a significant increase in the global loss volume (GLV) rate in both the NTG and AD patients when compared to the control subjects (P = 0.004, P = 0.006, P < 0.001, respectively). The statistical evaluation showed no difference in any RNFL or GCC parameters between the AD and NTG groups (P > 0.05). There was a negative correlation between disease duration and average RNFL and GCC thicknesses (r = -0.350, P = 0.027 and r = -0.471, P = 0.002, respectively) and a positive correlation between duration and GLV (r = 0.427, P = 0.006) in the AD group. Conclusion: The average RNFL thickness, GCC thickness, and GLV rates may help in the diagnosis of AD as an additional examination and may provide some important clues about the duration of the disease.
