Item Evaluation of macula with optical coherence tomography in patients with decreased visual acuity after successful retinal detachment surgery; [Başarılı Regmatojen Retina Dekolmanı Ameliyatlarından Sonra Görme Rehabilitasyonunun Saǧlanamadıǧı Olgularda Makulanın Optik Koherens Tomografi ile Deǧerlendirilmesi](Turkish Ophthalmology Society, 2012) Seymenoǧlu G.; Şahin B.Ö.; Top C.G.; Kayikçioǧlu O.; Başer E.Purpose: To study the foveal microstructural changes that may explain the incomplete visual recovery in eyes with anatomically successful repair of rhegmatogenous retinal detachments (RRD) using spectral-domain optical coherence tomography (OCT) and to evaluate the correlation between foveal changes and postoperative visual acuity. Material and Method: Forty-four eyes of 43 patients with macula-off RRDs were examined in our study. Patients were examined on first, third and sixth months postoperatively. The patients had a complete ophthalmological examination and OCT images were obtained at all postoperative visits. The postoperative OCT findings were classified in 4 groups: Group 1: continuous inner segment/outer segment (IS/OS) line, Group 2: disrupted IS/OS line, Group 3: epiretinal membrane (ERM), Group 4: residual foveal detachment. Results: Postoperative OCT findings showed that group 1 consisted of 19 eyes (43.2%), group 2 consisted of 15 eyes (34.1%), group 3 consisted of 7 eyes (15.9%) and group 4 consisted of 3 eyes (6.8%). The mean best-corrected visual acuity (BCVA) was significantly higher (p<0.001). Discussion: Spectral-domain OCT provides valuable information which helps the understanding of foveal microstructural changes and explains the possible causes of poor postoperative visual acuity in eyes with anatomically successful RRD repair.Item Comparison of pain response of patients undergoing panretinal photocoagulation for proliferati diabetic retinopathy: 532 nm standard laser vs. multispot pattern scan laser; [Proliferatif diyabetik retinopati nedeniyle panretinal fotokoagulasyon yapılan hastalarda aǧrı cevabının karşılaştırılması: 532 nm standart lazer vs multispot patern taramalı lazer](Turkish Ophthalmology Society, 2013) Seymenoǧlu G.; Kayikçioǧlu O.; Başer E.; Sami Ilker S.Purpose: To compare pain response of patients undergoing panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR) using 532 nm standard laser versus multispot pattern scan laser and to evaluate the relationship between pain response and patient characteristics. Material and Method: Thirty-five patients had PRP with the Pascal system in a single session, while other 35 patients had PRP with conventional laser in 2 sessions. Parameters used in conventional laser were as follows: spot size 200 μm, exposure time 0.2 s, and power sufficient to produce visible grey-white burns. We used same spot size, 20-30 ms exposure time, and higher levels of laser power in order to get a similar endpoint in the Pascal system. The patients were required to evaluate the severity of pain on a visual analog scale (VAS) and verbally 5 minutes after PRP with Pascal and 5 minutes after the first session of PRP with conventional laser. The relationship between pain experienced and patient characteristics was evaluated. Results: At baseline, both groups did not differ significantly (p >0.05, for all) with respect to sex, age, duration of diabetes, most recent HbA1c, treatment regimen, or patient experience. The patients in the Pascal group had a mean pain score of 0.55±0.70 on verbal scale and 1.54±1.22 on VAS compared to 2.17±1.18 and 5.54±3.28, respectively in the conventional laser group which was, statistically, significantly different in both scales (p<0.05). Discussion: Our study confirms that new generation pattern scanning photocoagulators satisfactorily decrease the pain by shortening the exposure time while increasing the laser power.Item Comparison of diagnostic accuracy of MRA and GPS algorithms using HR III device in glaucoma patients; [Glokom hastalari{dotless}nda hrt iii cihazi{dotless}nda mra ve gps algoritmalari{dotless}ni{dotless}n tani{dotless}sal deǧerlerinin karşi{dotless}laşti{dotless}ri{dotless}lmasi{dotless}](Turkish Ophthalmology Society, 2014) Oǧuz Ulusoy M.; Fatma Başer E.; Göktuǧ Seymenoǧlu R.; Özcan Kayikçioǧlu R.Objectives: The aim of this study is to evaluate the diagnostic accuracy of Moorfields regression analysis (MRA) and glaucoma probability score (GPS) and to measure the agreement between these two programs in classifying eyes as normal or abnormal. Materials and Methods: The study included 150 glaucoma patients followed in our glaucoma unit and 120 control subjects without glaucoma. All subjects underwent total ophthalmological examination, standard achromatic perimetry, and imaging of the optic nerve head with the Heidelberg Retina Tomograph II (HRT), using HRT III software, Version 3.0. The HRT parameters were compared between the two groups. The diagnostic accuracies of the two classifications were measured when the borderline was taken as either normal (highest specificity criteria) or abnormal (highest sensitivity criteria). The agreement between them was calculated using the kappa (κ) coefficient. Results: All HRT parameters except height variation contour in our study showed statistically differences between the control and glaucoma groups (p=0.000). The parameters with the highest area under curves were GPS global score (0.817), vertical cup/disc ratio (0.816), cup/disc area (0.808), and cup area (0.783). According to the highest specificity criteria, MRA had a sensitivity of 66% and specificity of 89.1% and GPS had a sensitivity of 62.7% and specificity of 81.6%. According to the highest sensitivity criteria, MRA had a sensitivity of 85.3% and specificity of 68.3% and GPS had a sensitivity of 90% and specificity of 60.8%. A moderate agreement of 65.9% (178 eyes) with a κ coefficient of 0.47 was found between MRA and GPS. Conclusion: In conclusion, GPS and MRA had a similar sensitivity, but the specificity of MRA was found to be higher than that of GPS. A moderate agreement was found between these analysis programs.Item Corneal haze and peripheral corneal arcus in a young patient: Lecithin-cholesterol acyltransferase deficiency; [Genç hastada kornea bulani{dotless}kli{dotless}ǧi{dotless} ve periferik kornea arkusu: Lesitin kolestrol açiltransferaz eksikliǧi](Turkish Ophthalmology Society, 2014) Mayali H.; Kiliç Ş.; Cansiz Ç.; Türkoǧlu M.Ş.; Başer E.F.A 23-year-old female patient applied to our clinic with the complaints of color changes in both of her corneas. Ophthalmological examination revealed 20/20 vision in both eyes. Intraocular pressure was 14 mmHg on the right eye and 12 mmHg on the left eye. Eye movements were normal and fundus examination revealed normal optic disc, macula, and peripheral retina. Biomicroscopic examination revealed diffuse haze in both of her corneas with circumferential arcus at the limbus and normal conjunctivae. Biochemical parameters were normal except for high-density lipoprotein values below 5 mg/ml, which was confirmed on repetitive tests. Together with ocular manifestations and low high-density lipoprotein values, a diagnosis of lecithin-cholesterol acyltransferase deficiency was made. In this article, a young patient who had low high density lipoprotein serum levels, peripheral corneal arcus, and corneal haze not affecting the visual acuity is presented.Item Evaluation of subclinical multiple sclerosis patients using pattern visual evoked potentials and visual field test; [Subklinik multipl skleroz hastalari{dotless}ni{dotless}n desen görsel uyari{dotless}lmi{dotless}ş potansiyeller ve görme alani{dotless} testi ile deǧerlendirilmesi](Turkish Ophthalmology Society, 2014) Bilgin S.; Ilker S.S.; Çavdar E.; Türker I.Objectives: The aim of this study was to evaluate subclinical multiple sclerosis (MS) patients with normal visual acuity using pattern visual evoked potentials (PVEP) test and central 30-2 threshold visual feld (VF) test. Materials and Methods: A total of 60 patients, 30 of which had a definitive MS diagnosis and 30 who were healthy volunteers, were included in the study. The participants were divided into the following three groups: Group 1 - optic neuritis (+) MS patients, Group 2 - optic neuritis (-) MS patients, and Group 3 - control group. Using white on white perimetry, SITA FAST central 30-2 threshold VF tests and 1°-0.3° PVEP measurements were performed. MD, PSD, p100 latency (ms), p100 amplitude (μV), and central 0-10°, 0-20°, 0-30°, 10-20°, 10-30°, 20-30° retina sensitivities (db) were evaluated in all groups. Results: There was a significant difference in all parameters between Group 1 and Group 3 (p<0.05). There was a significant difference in p100 latency 1°- 0.3°, p100 amplitude 0.3°, central 0-30°, 10-30°, 20-30° between Group 2 and Group 3 (p<0.05). There was no significant difference in the parameters except for p100 amplitude 1° between Group 1 and Group 2 (p>0.05). Conclusion: The evaluation of PVEP and central 30° VF can be used to monitor disease prognosis in subclinical MS patients.Item Neuroblastoma in a case with congenital horner's syndrome; [Konjenital horner sendromlu olguda nöroblastom](Turkish Ophthalmology Society, 2014) Mayali H.; Ilker S.S.; Kiliç Ş.; Sürücü B.; Ozgüven A.Miosis, ptosis, and ipsilateral facial anhidrosis are normally present in Horner's syndrome. Pathologies which show central, preganglionic and postganglionic residence in sympathetic chain are present in its etiology. A 3-month-old girl baby was admitted to our clinic for ptosis in the left eye. Heterochromia, ptosis in the left eye, myosis and, ipsilateral anhidrosis were detected in her examination. In view of these findings, it seemed possible that her disease could be congenital Horner's syndrome. Brachial plexus injury due to birth trauma plays a major role in the etiology of congenital Horner's syndrome. There was not any birth trauma history in our patient. The patient was diagnosed to have neuroblastoma as a result of etiologic tests. In conclusion, Horner's syndrome can be the presenting sign of childhood neuroblastoma. Therefore, it is advisable to examine the oculosympathetic system in detail in order to leave out any underlying serious disorder.Item Septo-optic dysplasia: A case report; [Septo-optik displazi: Olgu sunumu](Turkish Ophthalmology Society, 2014) Bilgin S.; Ilker S.S.; Türker I.; Kiliç S.An 18-year-old male patient was admitted with loss of vision in the right eye and blurred vision in the left eye. The right eye did not respond to the stimuli in the pattern visual evoked potentials (PVEP) test, and there was a signifcant delay in the p100 latency in the left eye. Cranial magnetic resonance imaging (MRI) showed a decrease in the calibration of both optical nerves, absence of septum pellucidum, and deformity in both frontal horns of the side ventricles. Despite the rare incidence of Septo-optik displazi (SOD), it should be considered in cases of unilateral or bilateral visual complaints, especially if optical nerve hypoplasia is also present.Item Evaluation of the effect of body position on intraocular pressure measured with rebound tonometer(Turkish Ophthalmology Society, 2019) Mayalı H.; Tekin B.; Kayıkçıoğlu Ö.R.; Kurt E.; İlker S.S.Objectives: It is important to determine variables that influence intraocular pressure (IOP) measurement. This study aimed to evaluate the effect of body position on IOP. Materials and Methods: The study included 52 right eyes of 52 patients who presented to the ophthalmology department of our hospital and had no ocular disease except refractive errors. IOP was measured with an Icare PRO tonometer while patients were in sitting, standing, and supine positions, with intervals of 10 minutes between the positions. Correlations between the results were evaluated using Spearman’s correlation analysis and Wilcoxon tests. Results: Thirty-six of the 52 patients were female, 16 were male. Mean age was 31.65±6.30 (23-47) years. Mean IOP values in the sitting, standing, and lying positions were 17.76±3.41 (12.70-25.60) mmHg, 17.10±3.27 (11.50-25.20) mmHg, and 18.46±4.67 (10.50-29.40) mmHg, respectively. There were no statistically significant differences between measurements taken in the different positions (p=0.112, p=0.472, p=0.071). We observed that there was no relationship between age and body position (p>0.45, p>0.79, p>0.77) or between gender and position (p>0.59, p>0.69, p>0.54). Conclusion: Gender and age had no effect on IOP measured in different body positions. There were also no significant differences between IOP values measured in the different positions. Therefore, we believe the portable Icare PRO tonometer can be used for patients who are confined to bed and will provide IOP measurements that are concordant with values obtained while sitting. © 2019 by Turkish Ophthalmological Association.Item Clinical results in patients with combined penetrating keratoplasty and vitreoretinal surgery using landers wide-field temporary keratoprosthesis(Turkish Ophthalmology Society, 2019) Mayalı H.; Kayıkçıoğlu Ö.; Altınışık M.; Bıçak F.; Kurt E.Objectives: To evaluate the clinical results of combined pars plana vitrectomy (PPV) with Landers wide-field temporary keratoprosthesis and penetrating keratoplasty (PK). Materials and Methods: From January 2016, traumatic eyes with coexisting corneal and vitreoretinal diseases that underwent combined keratoprosthesis/PPV/PK surgery were retrospectively evaluated. Demographic characteristics, visual acuity (VA), intraocular pressure (IOP) and clinical findings of the cornea, lens, and retina were recorded during the follow-up. Cases with clear corneal graft, attached retina, normotonic IOP, and improved or stable VA were considered successful. Results: Eight eyes were enrolled in the study. The mean follow-up time was 21.1±8.20 months. Surgery was performed a mean of 23 (10-40) days after trauma. Preoperative VA ranged from no light perception to counting fingers from 50 cm. Postoperatively, corneal graft was clear in 5 patients (62.5%) and retina was attached in 6 eyes (75%). Chronic hypotonia developed in 3 patients (37.5%). VA was unchanged in 3 patients and improved in 5 patients. A total of 5 cases (50%) were considered successful. Shorter interval between trauma and surgery was associated with higher likelihood of success (p=0.043). No significant difference was observed between the groups in terms of type or location of trauma (p=1; p=0.143). Conclusion: Although the functional results are not very satisfactory, the combined procedure provides a final opportunity for preserving remaining vision and anatomic reconstruction in eyes that will otherwise result in phthisis due to severe anterior and posterior segment pathologies. © 2019 by Turkish Ophthalmological Association.Item Comparison of icare pro tonometry and icare one tonometry measurements in healthy eyes(Turkish Ophthalmology Society, 2019) Mayalı H.; Sarıgül Ç.; Kurt E.; Kayıkçıoğlu Ö.R.; İlker S.S.Objectives: To compare intraocular pressure (IOP) measurements obtained with the Icare Pro tonometer used in clinical practice and the Icare One self-tonometer. Materials and Methods: Fifty-two eyes of 52 healthy, right-handed individuals with no prior intraocular surgery or ocular trauma, structural ocular pathology, or systemic disease were evaluated. IOP was first measured using the Icare Pro tonometer. The participants were then told how to use the Icare One tonometer and asked to measure their own IOP. The results were analyzed statistically using SPSS v.24. Results: Of the 52 healthy participants, 16 (30.7%) were male and 36 (69.3%) were female. Their mean age was 31.6±6.3 (23-47) years. Mean IOP measured with the Icare Pro was 17.10±6.2 (11.5-25.2) mmHg, and the mean self-measured IOP with Icare One was 14.01±3.4 (7-24) mmHg. When the two methods were compared using Levene’s t-test, there was a significant mean difference of -3.08±0.6 (95% confidence interval: -4.39 -1.78; p<0.001). Conclusion: In this study, there was a significant difference between the IOP measurements we made using the Icare Pro and the participants’ self-measured IOP using the Icare One, with the latter being relatively lower. This may be related to the fact that the participants were unfamiliar with using the Icare One. Although the Icare One is a promising tool for glaucoma patients to self-monitor their IOP, further studies are needed. © 2019 by Turkish Ophthalmological Association.Item Anterior chamber migration of ozurdex implants(Turkish Ophthalmology Society, 2020) Kayıkcıoğlu Ö.; Doğruya S.; Sarıgül C.; Mayalı H.; Kurt E.We present patient characteristics and follow-up results of cases with anterior chamber dexamethasone implant migration. The common feature of all six presented cases was vitrectomized eyes. Four of the patients had sutured intraocular lens (IOL) implantation due to complicated cataract surgery, one had combined retinal detachment surgery with sutured IOL implantation, and one had vitrectomy for diabetic intravitreal hemorrhage cleaning and uncomplicated cataract surgery. Anterior chamber implant migration caused corneal edema in all cases and elevated intraocular pressure in three cases. In two cases, the dexamethasone implant was directed into the vitreous cavity after maximum pupillary dilation and corneal manipulation with cotton tip applicator with the patient in reverse Trendelenburg position. There was no other complication until dexamethasone implant degradation, with clear cornea at final examination. In two cases, the implant was removed from the anterior chamber by aspiration, but keratoplasty surgery was planned due to endothelial cell loss and persistent corneal edema during follow-up. In the last two cases, the dexamethasone implant was redirected into the vitreous chamber with a 23-gauge catheter and anterior chamber maintainer but they migrated into the anterior chamber again. In one of these patients, the implant was aspirated by catheter and corneal transplantation was performed due to corneal edema, while the other patient’s implant was redirected into the vitreous chamber with no further anterior migration. The risk of dexamethasone implants migrating into the anterior chamber of vitrectomized eyes and those with sutured IOL implantation should be kept in mind and the patient should be informed and advised to see an ophthalmologist immediately before permanent corneal endothelial damage occurs. © 2020 by Turkish Ophthalmological Association.Item Efficacy of topical brinzolamide treatment in posterior microphthalmos-related macular cystoid lesions: A case series(Turkish Ophthalmology Society, 2020) Engin C.D.; Ekinci U.B.; Selver A.; Saatçi A.O.The aim of this study was to report the outcome of topical brinzolamide 1% treatment on macular cystoid lesions resembling retinoschisis in 4 patients diagnosed with posterior microphthalmia. The medical records of 4 patients with a clinical diagnosis of posterior microphthalmia who had started topical brinzolamide 1% treatment were reviewed. Visual acuity, central foveal thickness, and cystoid lesion area percentage were used to evaluate treatment response. In the follow-up, there was a decrease in central foveal thicknesses and cystoid lesion area percentages in both eyes of 3 of the patients. However, 1 patient showed increases in both parameters. Visual acuity remained stable in 5 eyes and increased in 3 eyes. Topical brinzolamide treatment may have some positive effects on macular cystoid lesions in selected cases. © 2020 by Turkish Ophthalmological Association Turkish Journal of Ophthalmology, published by Galenos Publishing House.Item Unintentional staining of the anterior vitreous with trypan blue during cataract surgery(Turkish Ophthalmology Society, 2020) Kayıkçıoğlu Ö.R.; Mayalı H.; Doğruya S.; Alp Ş.; Yılmazlar A.A.; Kurt E.During phacoemulsification and intraocular lens (IOL) implantation surgery, the trypan blue dye used to stain the anterior capsule passed into vitreous cavity and stained the anterior capsule and anterior vitreous in 6 patients. There was history of trauma in 2 patients, uveitis in 1 patient, mature cataract in 1 patient, and no risk factors in the other patients. IOL was implanted in-the-bag without problem in 5 patients. In the patient with iris and zonular defects due to trauma, a sutured IOL was implanted in the same session. The migration of trypan blue into the vitreous cavity through damaged or intact lens zonules is a rare but important complication that makes subsequent surgical steps substantially more difficult. © 2020 by Turkish Ophthalmological Association Turkish Journal of Ophthalmology, published by Galenos Publishing House.Item Reply to letter to the editor re: “unintentional staining of the anterior vitreous with trypan blue during cataract surgery”(Turkish Ophthalmology Society, 2021) Kayıkçıoğlu Ö.; Mayalı H.; Doğruya S.; Alp Ş.; Yılmazlar A.A.; Kurt E.[No abstract available]Item Pulsatile Proptosis and Sphenoid Wing Dysplasia with no Evidence of Neurofibromatosis Type 1: A Case Report and Review of the Literature(Turkish Ophthalmology Society, 2024) Delibay Akgün Y.; Erdoğan M.; Altınışık M.; Mayalı H.; İlker S.S.In this study, we aimed to present a rare case of pulsatile proptosis due to sphenoid wing dysplasia without the features of neurofibromatosis type 1 (NF1). A 17-year-old male patient presented with swelling in the superotemporal region of the right eye. Physical examination revealed facial asymmetry with a pulsatile, ill-defined, soft lesion with in the superotemporal region of the right orbit associated with pulsatile proptosis, downward dystopia, and hypotropia. Computer tomography imaging to establish a differential diagnosis showed temporal lobe herniation secondary to sphenoid wing dysplasia. The patient was assessed for NF1, which is most commonly associated with sphenoid wing dysplasia, but no evidence supporting the diagnosis was found. Patients presenting with proptosis should be carefully examined for pulsation and murmurs, and a trauma history should be investigated. Radiological imaging should be used to facilitate the differential diagnosis, and the current clinical condition should be managed with a multidisciplinary approach. © 2024 by the Turkish Ophthalmological Association / Turkish Journal of Ophthalmology published by Galenos Publishing House.
