Öğe Apart From Surgical Procedures, Another Important Point to Note in Lacrimal Canalicular Lacerations: Traumatic Retinal Tears(Lippincott Williams & Wilkins, 2019) Demirel, Soner; Dikci, Seyhan; Firat, Penpe Gul; Genc, Oguzhan; Mutlu, KayhanBackground: To evaluate fundus examinations in terms of traumatic retinal tears or dialysis that may be related to canalicular lacerations (CLs). Materials and Methods: This retrospective study was conducted on patients with CL repair from June 1, 2009 to May 30, 2018. The authors collected the data from the patients' medical records, including their demographic details, mechanism and setting of injury, associated ocular injuries, type of stent used, setting of repairs, duration of follow-up, complications, pre- or intraoperative findings of biomicroscopic and fundus examinations, refractive errors, postoperative follow-up of fundus examination, and management. Results: Sixty patients (43 males and 17 females) were included in the study. The mean age of all the patients was 27.50 +/- 21.72 (min: 1-max: 94) years. Isolated CL was found in 38 patients. Nonisolated CL, which means with some additional pathologies, were found in 22 patients (37%, approximately 1/3). Retinal follow-up records were available in 49 patients with a mean follow-up period of 7.48 +/- 9.82 months. Retinal tears were seen in 3 patients (0.05%) with no predisposing risk factors. Two of these tears were found in the follow-up period after the traumas. Conclusion: Consequent retinal tears after canalicular lacerations were not strongly addressed in previous works. In this study, the authors aimed to view CL from a different perspective. Canalicular laceration is also an ocular trauma that may threaten vision. The authors emphasized that performing detailed fundus examinations and follow-up in all canalicular traumas is necessary.Öğe Bilateral retinal vasculitis in a patient with lichen planus(Consel Brasil Oftalmologia, 2016) Dikci, Seyhan; Genc, Oguzhan; Yilmaz, Turgut; Firat, Penpe GulLichen planus (LP) is an autoimmune, inflammatory disease of unknown etiology that commonly affects the skin and mucous membranes. Retinal vasculitis is a group of vision-threatening disorders, in which autoimmunity is thought to play a role in pathogenesis. We present the case of a patient who was diagnosed with retinal vasculitis and who was followed up for mucosal LP. LP has not been reported as a cause of retinal vasculitis in the literature. We believe that the retinal vasculitis in this case was related to LP because cellular immunity plays a role in the pathogenesis of both entities.Öğe Characteristics of Open Globe Injuries in Preschool Children(Lippincott Williams & Wilkins, 2015) Gunes, Alime; Kalayci, Mustafa; Genc, Oguzhan; Ozerturk, YusufPurpose To evaluate the demographic, etiologic, and clinical characteristics of open globe injuries in preschool children. Methods The medical files of preschool children who had an operation for an open globe injury from January 2003 to January 2013 were retrospectively analyzed. The patients' demographics and injury characteristics were recorded. Results The study consisted of 44 preschool children with an open globe injury. The mean age was 4.38 1.39 years. Most of the injuries occurred in boys (32/44). All patients were followed up for at least 3 months (mean, 8.47 +/- 6.38 months; range, 3-24 months). The mean time between injury and operation was 10.40 +/- 5.94 hours. Injuries happened most frequently at home (45.4%), and the most common cause of injury was kitchen items (25%). The final visual acuity could be evaluated only in 21 patients, and 90.4% of them had residual vision deficit. Conclusions Because open globe injuries occur most frequently at home or in the immediate surroundings of the house, higher awareness of parents and child care providers is extremely important to prevent these injuries in preschool children.Öğe Comparison of intravitreal ranibizumab and bevacizumab treatment for retinopathy of prematurity(Consel Brasil Oftalmologia, 2016) Ceylan, Osman Melih; Dikci, Seyhan; Genc, Oguzhan; Yilmaz, Turgut[Abstract Not Available]Öğe Evaluation of Iron Deficiency Anemia Frequency as a Risk Factor in Glaucoma(Hindawi Ltd, 2018) Firat, Penpe Gul; Demirel, Ersan Ersin; Dikci, Seyhan; Kuku, Irfan; Genc, OguzhanPurpose. Iron deficiency anemia is an important public health problem. Also it is considered to be a risk factor for many diseases. The study demonstrates the iron deficiency anemia frequency in glaucoma patients and compares with the normal subjects. We aimed to determine the iron deficiency anemia frequency in glaucoma patients. Methods. Prospective, controlled study in a single university hospital setting. A total of 130 normal subjects (Group 1) and 131 glaucoma patients (Group 2) were included. The erythrocytes parameters, hemoglobin, red blood cell, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, and red blood cell distribution width, and iron status indicators, Fe (iron), total iron binding capacity, and ferritin of the cases, in normal subjects and glaucoma patients were compared. Results. There was no statistically significant difference for the erythrocyte parameters between the groups (p >= 0.05). The number of the patients with iron deficiency anemia in both groups was similar. No statistically significant difference was found in the comparison of erythrocyte parameters and iron status indicators values according to the number of antiglaucomatous agents and visual field changes according to the presence of anemia in Group 2 (p >= 0.05). A statistically significant difference was found only in MCH when the erythrocyte parameters and iron status indicators values of the cases in glaucoma patients were compared with the glaucoma duration (p<0.05). Conclusion. The iron deficiency anemia frequency was like the normal population in glaucoma patients.Öğe Evaluation of the Cornea and Anterior Chamber Morphologic Changes After Penetrating Keratoplasty in Patients With Keratoconus(Lippincott Williams & Wilkins, 2017) Ort, Abdulkadir; Gunes, Alime; Kandemir, Baran; Calisir, Kenan; Kalayci, Mustafa; Genc, Oguzhan; Ozerturk, YusufObjectives: To evaluate changes of the cornea and anterior chamber after penetrating keratoplasty in eyes with keratoconus. Methods: Medical records of 68 eyes of 68 patients with keratoconus who experienced penetrating keratoplasty at the Eye Clinic of Dr. Lutfi Kirdar Kartal Research and Training Hospital between 2010 and 2012 were studied. Records were retrospectively evaluated with regard to anterior chamber depth, iridocorneal angle, central corneal thickness, thinnest corneal thickness, maximum keratometric value, and mean keratometric value. Patients who developed complications and required additional surgery were excluded. Results: A total of 68 eyes of 68 patients were included in this study. There were 40 (58.8%) male and 28 (41.2%) female patients. The mean age was 24.5 +/- 8.19 years (range: 11-42 years). The graft diameter was 7.5 mm and the recipient bed diameter was 7.0 mm in all patients. The preoperative anterior chamber depth decreased from 3.92 +/- 0.47 mm to 3.01 +/- 0.55 mm (23% decrease). No significant postoperative change was observed in the mean iridocorneal angle values. Keratometric values decreased by 30% and corneal thickness increased by 50% (P< 0.001 for both). Conclusion: Anterior chamber depth decreased significantly, but no change was observed in iridocorneal angle after penetrating keratoplasty in patients with keratoconus. Also, a decrease in the keratometric values and an increase in corneal thickness were observed. Understanding, estimating, and managing changes in the anterior chamber after penetrating keratoplasty, which induces significant changes in anterior chamber morphology, might increase the success of surgery.Öğe Evaluation of ıron deficiency anemia frequency as a risk factor in glaucoma(Hındawı ltd, adam house, 3rd flr, 1 fıtzroy sq, london, w1t 5hf, england, 2018) Firat, Penpe Gul; Demirel, Ersan Ersin; Dikci, Seyhan; Kuku, Irfan; Genc, OguzhanPurpose.

Diagnosis of this disorder is based upon characteristic clinical findings and a positive histoplasmin skin test or residence in an endemic region for Histoplasma capsulatum. There is no active systemic disease during diagnosis of POHS. Disciform scarring and macular CNV secondary to POHS is a well-known complication which leads to loss of visual acuity or visual disturbance. Without therapy, the visual prognosis in these patients is unfavorable. Submacular surgery, radiation, steroids, photodynamic therapy, and most recently anti-vascular endothelial growth factor therapy are current therapeutic options for this condition. We report a case with persistent CNV secondary to POHS in a middle-aged woman with moderate myopia and the clinical course of treatment with multiple intravitreal ranibizumab (Lucentis (R), Novartis) injections.Öğe Results of Diod Laser Photocoagulation in the Treatment of Retinopathy of Prematurity(Karger, 2014) Dikci, Seyhan; Genc, Oguzhan; Yilmaz, Turgut; Firat, Penpe Gul; Demirel, Soner[Abstract Not Available]
