Publication Open Access Predictive factors of complications and visual outcomes after pediatric cataract surgery: A single referral center study from Türkiye(2023-10-01) DERİCİOĞLU, VOLKAN; SEVİK, MEHMET ORKUN; BAĞATUR VURGUN, ELİF; ÇERMAN, EREN; DERİCİOĞLU V., SEVİK M. O., BAĞATUR VURGUN E., ÇERMAN E.Objectives: To evaluate the predictive factors of complications and visual acuity outcomes in pediatric cataract patients. Materials and Methods: This retrospective, observational clinical study included 80 eyes of 50 patients treated for pediatric cataracts between 2010 and 2020. The eyes were divided into Group I (congenital cataracts, n=38) and Group II (developmental cataracts, n=42). Group II was also divided into Group IIA (aphakic, n=21) and Group IIB (pseudophakic, n=21). The effects of the age, laterality, cataract morphology, intraocular lens implantation, preoperative nystagmus/strabismus, and intraoperative anterior hyaloid rupture on complications and final best-corrected visual acuity (BCVA; logMAR) were evaluated. Results: The median (interquartile range) age and follow-up time were 28 (5-79) months and 60 (29-84) months, respectively. There was a significant difference in mean final BCVA between Group I (0.79±0.46) and Group II (0.57±0.51) (p=0.047); however, no difference was observed between Group IIA and Group IIB (p=0.541). Having congenital cataract (p=0.045), preoperative nystagmus/strabismus (p=0.042), total/ mature cataract (p<0.001), and postoperative complications (p=0.07) were significantly associated with final BCVA. However, in multivariate analysis, only total/mature cataract (β: 0.52, p<0.001) and having any complication (β: 0.24, p=0.018) were associated with final BCVA. Congenital cataract and intraoperative anterior hyaloid rupture were the only significant risk factors of postoperative complications on univariate (p=0.027 and p=0.003, respectively) and binary logistic regression analysis (odds ratio [OR]: 2.95 [95% confidence interval: 1.07-8.15], p=0.036 and OR: 4.28 [95% confidence interval: 1.55-11.77], p=0.005, respectively). Conclusion: Total/mature cataract and the presence of any postoperative complication adversely affected the final BCVA. Having a congenital cataract and intraoperative anterior hyaloid membrane rupture increased the risk of complications.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 Quantitative measurement of horizontal strabismus with digital photography(MOSBY-ELSEVIER, 2019) ÇERMAN, EREN; Dericioglu, Volkan; Cerman, ErenPURPOSE To develop a method to calculate the gaze angle in photographs and to determine its validity and reliability in real strabismus patients. METHODS Photographs of eyes from 15 orthophoric subjects (n = 1,022) with known gaze angle and imaging distance were investigated with the help of a smartphone application developed by the authors. The application provided measurements of the distance from the geometrical center of the cornea to the light reflex (RD) and corneal diameter (CD). The RD/CD ratio of each gaze angle was recorded. To estimate the eyes' gaze angle, an equation to determine the best-fit line for the gaze angle data according to each RD/CD ratio was created. In a second clinical analysis, this equation was applied to photographs of real strabismus patients (n = 72), and the results were compared with measurements taken by a double-masked strabismus specialist. Separately, an equation was created to calculate the imaging distance using the given interpupillary distance. RESULTS There was a high correlation between the real and estimated gaze angles (r = 0.990, P < 0.001). The mean error of the estimated gaze angle was found to be 0.03(Delta) +/- 4.60(Delta). There was a high correlation between the real and estimated imaging distance (r = 0.997, P < 0.001) and a high correlation between the measurements of the application and the specialist (r = 0.966, P < 0.001). The average error was -0.68(Delta) +/- 6.1(Delta), and the reliability was high (Cronbach's alpha = 0.983). CONCLUSIONS The application measured horizontal strabismus in photographs with high reliability.Publication Open Access Effect of age on primary balloon dacryocystoplasty and probing success in congenital nasolacrimal duct obstruction(2022-11-01) ÇERMAN, EREN; SEVİK, MEHMET ORKUN; ERASLAN, MUHSİN; DERİCİOĞLU, VOLKAN; DERİCİOĞLU V., Sevik M. O., Sacu S. S., ERASLAN M., ÇERMAN E.Purpose To compare the success rates of balloon dacryocystoplasty (BDP) and probing as a primary procedure in congenital nasolacrimal duct obstruction (CNLDO) and investigate the effect of age on both procedures. Methods A total of 135 patients (171 eyes) with simple and incomplete complex CNLDO were included in this retrospective study; complete complex CNLDO cases were excluded. The success rates for primary BDP (118 eyes) and for probing (53 eyes) were compared overall and among the age groups; Group 1 (12-24 months old), Group 2 (25-36 months old), and Group 3 (> 36 months old). Results Mean age of the patients was 41.5 +/- 27.2 months for primary BDP, and 21.8 +/- 10.8 months for probing (p < 0.001). Overall success rates for primary BDP and probing were 81.1% (43/53) and 76.3% (90/118), respectively (p = 0.481). Success rates for BDP and probing among age groups were 93.8% and 85.3% in Group 1 (p = 0.360), 93.3% and 50.0% in Group 2 (p = 0.012), and 63.6% and 27.3% in Group 3 (p = 0.052), respectively. Cox regression analysis showed that the median ages were 18 months for probing and 36 months for primary BDP. The Poisson regression model showed that for every 1-month increase in patients\" age, the success rate of probing decreased by 9.7%. Conclusion Probing success decreased to a point where different treatment options such as primary BDP can be discussed with the patients\" parents after 18 months of age. The success of BDP decreased after 36 months, while it maintained a high success rate between 24 and 36 months as primary treatment.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.
