Bilateral Optic Atrophy Related To Juvenile Nasopharyngeal Angiofibroma
(Taylor & Francis As, 2008) Caglar, Cagatay; Cinal, Adnan; Avcu, Serhat
Juvenile nasopharyngeal angiofibroma (JNA) is one of the most common benign nasal cavity tumors of adolescence. This tumor has the capacity to locally expand. It can cause ocular manifestations such as proptosis, decreased visual acuity, and visual field deficits. In our case, JNA caused visual loss in both eyes. Our case showed that despite the fact that the tumor is benign, it can cause serious complications, such as blindness. Therefore, early diagnosis and treatment is crucial for this type of tumor and an ophthalmologist should be most alert for symptoms of JNA.
Comparing Biometry in Normal Eyes of Children With Unilateral Cataract/Corneal Disease To Age-Matched Controls
(Nepal Ophthalmic Soc, 2015) Gul, Adem; Cinal, Adnan; Caglar, Cagatay; Yasar, Tekin; Kilic, Adil
Objective: To compare ocular biometry and central corneal thickness of unaffected healthy eyes of pediatric patients with monocular cataracts/corneal opacities and age-matched controls. Materials and methods: We studied 329 eyes of 329 children who were between 1 and 12 years old. The study group (n: 164) consisted of healthy fellow eyes of children operated for unilateral congenital/traumatic cataract and corneal laceration. Axial length, anterior chamber depth, lens thickness, vitreous chamber depth, and central corneal thickness were measured by ultrasound biometry/pachymetry. Results: Axial length was 22.16 mm in the study group and 21.99 mm in the control group. Anterior chamber depth, lens thickness, and vitreous chamber depth results were 3.35; 3.64 and 15.20 in the treatment group and 3.20; 3.63, and 15.15 mm in the control group, respectively. The axial length and all the components, i.e. anterior chamber depth, lens thickness, and vitreous chamber depth are higher in the unaffected healthy eyes of the pediatric patients than that of the control group but only the difference in the anterior chamber depth was statistically significant. The central corneal thickness was 548 microns and 559 microns in the study and the control groups, respectively, and the difference was found to be significant. Conclusion: Greater anterior chamber depth was chiefly responsible for the overall increase in the axial length in the study group. The central corneal thickness was significantly thinner in the study group than that of the control group.
Comparison of Heidelberg Retina Tomograph-3 Glaucoma Probability Score and Moorfields Regression Analysis of Optic Nerve Head in Glaucoma Patients and Healthy Individuals
(Springer, 2017) Caglar, Cagatay; Gul, Adem; Batur, Muhammed; Yasar, Tekin
To compare the sensitivity and specificity of Moorfields regression analysis (MRA) and glaucoma probability score (GPS) between healthy and glaucomatous eyes with Heidelberg Retinal Tomograph 3 (HRT-3). The study included 120 eyes of 75 glaucoma patients and 138 eyes of 73 normal subjects, for a total of 258 eyes of 148 individuals. All measurements were performed with the HRT-3. Diagnostic test criteria (sensitivity, specificity, etc.) were used to evaluate how efficiently GPS and MRA algorithms in the HRT-3 discriminated between the glaucoma and control groups. The GPS showed 88 % sensitivity and 66 % specificity, whereas MRA had 71.5 % sensitivity and 82.5 % specificity. There was 71 % agreement between the final results of MRA and GPS in the glaucoma group. Excluding borderline patients from both analyses resulted in 91.6 % agreement. In the control group the level of agreement between MRA and GPS was 64 % including borderline patients and 84.1 % after excluding borderline patients. The accuracy rate is 92 % for MRA and 91 % for GPS in the glaucoma group excluding borderline patients. The difference was nor statistically different. In both cases, agreement was higher between MRA and GPS in the glaucoma group. We found that both sensitivity and specificity increased with disc size for MRA, while the sensitivity increased and specificity decreased with larger disc sizes for GPS. HRT is able to quantify and clearly reveal structural changes in the ONH and RNFL in glaucoma.
Could Visual Impairment in the Pediatric Age Group Be Reduced
(Turkish Ophthalmological Soc, 2013) Ceyhan, Dogan; Yasar, Tekin; Caglar, Cagatay
Pediatric age is the most important period for preventive eye care services and research. Vision loss in this period could cause a long life without sight and also significant financial and moral losses, in terms of people and society. Rational screening programs may reduce vision loss in childhood and this issue increases the value of the subject. Retinopathy of prematurity, congenital/infantile cataracts and glaucoma, optic nerve and retinal pathologies, refractive errors, amblyopia, and strabismus are the major clinical pictures causing visual loss in childhood. Using the epidemiological data, it could be estimated that every year approximately two to three thousand children suffer an ophthalmologic disease that causes significant visual loss. Regarding the refractive errors and amblyopia, it could be estimated that hundreds of thousands of children need ophthalmological follow-up in the country. For the timely treatment of these pathologies, a couple of short eye examination programs seem more realistic. Childhood vision loss in the country could be reduced, by informing pediatricians and family physicians and by proper guiding of the public opinion. Effective eye screening could be achieved with the implementation of simple methods like red reflex/Bruckner test with ophthalmoscopy, or simultaneous ( binocular) retinoscopy and ophthalmoscopy of both eyes. Screening programs could be spread throughout the country by appropriate training of the physicians in the health institutions of the country. Screening programs will contribute to reduce the rate of visual disability by disseminating ophthalmologic practices throughout the country.

(Turkish Ophthalmological Soc, 2010) Gul, Adem; Yasar, Tekin; Caglar, Cagatay; Esmer, Oktay
Purpose: Endophthalmitis is an inflammation of the intraocular structures and is mostly associated with open-globe injuries and various surgical eye interventions. In this study, we investigated the endophthalmitis rate in patients who underwent primary repair of open-globe injury. Material and Method: We retrospectively reviewed the records of patients with open-globe injuries who had attended YOzUncti Yil University, Department of Ophthalmology between 1993 and 2009. We analyzed the data of 810 patients who had undergone primary repair; of those, 64 patients had developed endophthalmitis. Results: Endophthalmitis rate was 7,9% (64 patients). Perforating eye injury was commonly seen between 2 and 6 years of age; 56 cases (.1:0/0) were with corneal, 2 (3%-with scleral, and 6 cases (9%) were with corneoscleral perforation. Regarding the time between the onset of endophthalmitis and trauma, 11 (17%) patients developed endophthalmitis in the first 12 hours, 15 (23%)-between 12-24 hours, 13(20%)-on the second day, 13 (20%)-on the third day, and the remaining 12 patients-between the fourth and 30th day. The range of the follow-up period was 2 days-96 months. The most common agents in patients who developed posttraumatic endophthalmitis were metal objects such as fork, knife, needle, injector (39%), wood and thorn (23%) and the remaining were stone, glass, and animal-related factors like horn. Discussion: It was seen that 64 out of 810 patients (7,9%) in our clinic developed endophthalmitis after primary repair of penetrating eye injury.

In Vivo Confocal Microscopy and Biomicroscopy of Filtering Blebs After Trabeculectomy
(Lippincott Williams & Wilkins, 2016) Caglar, Cagatay; Karpuzoglu, Nafiz; Batur, Muhammed; Yasar, Tekin
Purpose: The aim of this study is to analyze filtering blebs (FBs) after trabeculectomy with in vivo confocal microscopy (IVCM) and slit-lamp biomicroscopy. Materials and Methods: IVCM using the Heidelberg Retina Tomograph/Rostock Cornea Module and biomicroscopic examination were performed in 67 FBs in 55 patients 3 months to 30 years postoperatively (mean, 3.2 +/- 2.1 y). Although the blebs were evaluated by slit-lamp biomicroscopy, standardized FB classification was used. Results: Of the patients, 9 were female (16.3%) and 46 were male (83.7%), ranging in age from 32 to 81 (51.5 +/- 13.2) years. The absence of vascularization and tortuous vessels and the presence of epithelial microcysts on the bleb were significantly correlated with good bleb function (P = 0.001). IVCM findings significantly correlated with good bleb function, including the number of epithelial microcysts (P = 0.002), the stromal cysts without capsule (P < 0.001), minimal vascularization (P = 0.002), and the absence of tortuous conjunctival vessels (P = 0.003) and reticular and trabecular bleb patterns (P = 0.01 and < 0.01, respectively). In contrast, a hyperreflective condensed bleb stroma was significantly associated with bleb failure (P < 0.001). Conclusions: IVCM supports biomicroscopic evaluation as the mainstay for FB analysis and permits diagnostic imaging of FBs to evaluate and follow-up the bleb, differentiation between good and insufficient bleb function, and a microscopic analysis at a cellular level including the structural pattern of the bleb.
Ocular Biometry and Central Corneal Thickness in Children: a Hospital-Based Study
(Consel Brasil oftalmologia, 2014) Gul, Adem; Caglar, Cagatay; Cinal, Adnan; Yasar, Tekin; Kilic, Adil
Purpose: To investigate the distribution of axial length, anterior chamber depth, lens thickness, vitreous chamber depth, and central corneal thickness in children at different age groups. Methods: We studied 364 eyes in 182 children with ages between 1 and 12 years. Axial length, anterior chamber depth, lens thickness, and vitreous chamber depth were measured by ultrasound biometry. Central corneal thickness was measured by ultrasound pachymetry in all children. Results: The mean age was 6.54 +/- 3.42 years. The axial length was 20.95 mm in 1-2 years old and 22.95 mm in 11-12 years old. The central corneal thickness was 556 mu m in 1-2 years old and 555 mu m in 11-12 years old. The mean anterior chamber depth and vitreous chamber depth increased with age (3.06 mm to 3.44 mm in anterior chamber depth, 13.75 mm to 15.99 mm in vitreous chamber depth), and the lens thickness decreased as age increased (3.67-3.51 mm). Conclusion: The axial length increased with age and reached adult levels by the age of 9-10 years. The lens thickness gradually decreased until 12 years. The central corneal thickness measurements did not yield a linear algorithm.
The Outcomes of Lacrimal Massage or Probing Treatments at Early and Late Ages for Congenital Nasolacrimal Duct Obstruction
(Aves, 2010) Caglar, Cagatay; Batur, Muhammed; Yasar, Tekin; Cinal, Adnan
Aim: To determine the success rates of lacrimal massage and probing according to age groups for congenital nasolacrimal duct obstruction (CNDO) and emphasize the outcomes of these treatments at early and late ages. Material and Method: Between April 2000 and March 2009, two hundred and ninety-four eyes of 203 patients diagnosed with congenital nasolacrimal duct obstruction were retrospectively examined. According to symptoms and age, patients were treated with lacrimal massage and antibiotic therapy or probing and irrigation under general anesthesia. The cases were divided into two groups: Group 1 (lacrimal massage and antibiotic treatment) and Group 2 (probing and irrigation treatment). Results: In group 1, the cases were 1-42 months of age (mean 16.6 +/- 10.4 months) and were followed-up 2-32 months (mean 9.5 +/- 8.4 months). Proportions of eyes treated successfully were 53.7% overall, 96% for the 25 eyes in children 0 to 6 months old, 51.3% for the 37 eyes in children 7 to 12 months, 53.3% for the 30 eyes in children 13 to 18 months, and 39.7% for the 68 eyes in children 19 to 36 months. In group 2, the cases were 9-84 months of age (mean 24.5 +/- 13.1 months) and were followed-up 2-38 months (mean 11.1 +/- 10.6 months). Proportions of eyes treated successfully were 86.5% overall, 94.1% for the 17 eyes in children 9 to 12 months old, 93.1% for the 44 eyes in children 13 to 18 months, 93.7% for the 32 eyes in children 19 to 24 months, 84% for the 25 eyes in children 25 to 36 months, 71.4% for the 7 eyes in children 37 to 48 months, and 66.6% for the 9 eyes in children 49 to 84 months. Conclusions: In the 0-1 age group, lacrimal massage and antibiotic treatment are the first therapeutic option. Early probing before 12 months of age should be refrained from unless symptoms such as dacryocystitis or severe blepharitis are presented. We consider that delay in probing is a viable option with mild symptoms up to the age of 18 months, or later if the parents wish it. Probing is successful in the older age group and can be performed up to the age of 5 years, but the success rates decrease with increasing ages of cases. (Turk Arch Ped 2010; 45: 359-65)

Results of Traumatic Cataract Surgery After Penetrating Corneal Trauma With Corneal Healing Without Suturing
(Turkish Ophthalmological Soc, 2010) Caglar, Cagatay; Yener, Halil Ibrahim; Gul, Adem; Yasar, Tekin
Purpose: To evaluate the preoperative signs, complications of cataract surgery and visual outcomes in cases of corneal healing without suturing after penetrating corneal trauma. Material and Method: We performed a retrospective analysis of 68 eyes (68 patients) with traumatic cataract after penetrating corneal trauma with a penetrating object, and which corneal healing was achieved without suture. All patients underwent traumatic cataract surgery and intraocular lens (IOL) implantation in our clinic. Patient demographics, causes of injury, corneal wound categories, interval of subsequent IOL implantation, preoperative visual acuity, postoperative best-corrected visual acuity, and preoperative, intraoperative and postoperative complications were analyzed in all patients. Patients were divided into two groups: the first group was composed of emergently admitted patients after ocular trauma, while the second group included subjects with decreased visual acuity in the late period. Results: The mean age of the patients was 12.97 +/- 13.16 years (range, 2.5-67). Most patients were children or young men. The most common etiological agents of penetrating ocular trauma were wood (30.8 %), sharp metal object (22%) and injector needle (8.8 %). The mean preoperative and postoperative visual acuities were 0.02 +/- 0.05 (Snellen) and 0.5 +/- 0.36, respectively. The mean visual improvement after traumatic cataract surgery and IOL implantation was statistically significant (p<0.05). Thirty-six eyes (53%) achieved final best-corrected visual acuity of 0.4 or better. Discussion: Satisfying results in visual outcome can be seen with appropriate treatment and close follow-up after traumatic cataract surgery in cases of penetrating corneal trauma with corneal healing achieved without suturing.

(Taylor & Francis inc, 2017) Caglar, Cagatay; Batur, Muhammed; Eser, Eray; Demir, Habip; Yasar, Tekin
Purpose: To determine the stabilization time of automated refraction, ocular biometric parameters, keratometry, and central corneal thickness (CCT) and to find the optimal time for glasses' prescription after cataract surgery. Methods: This was a prospective, case series study of 62 consecutive eyes with senile cataracts. Patients undergoing uncomplicated phacoemulsification surgery were included in the study. Automated refraction, keratometry, ocular biometric parameters, and CCT were recorded at baseline before cataract surgery and at follow-up visits at one day, one week, two weeks, and four weeks after surgery. Results: The study was composed of 62 eyes of 62 patients with a mean age of 66 +/- 12.38 (range, 40 to 84 years). The automated refraction stabilized one week after surgery and changed minimally between the first week and the first month after cataract surgery. The stabilization of average keratometric corneal astigmatism in keratometry, average anterior chamber depth, and CCT was achieved after the second postsurgical week. Conclusion: It may be possible to prescribe glasses starting from two weeks after an uneventful phacoemulsification cataract surgery for most patients.

(Mary Ann Liebert inc, 2012) Caglar, Cagatay; Yasar, Tekin; Ceyhan, Dogan
Purpose: The aim of this article is to create awareness among medical colleagues regarding the severe ophthalmic side effects associated with topiramate use. Methods: A case of severe acute bilateral angle closure glaucoma with visual blurring after oral topiramate therapy. Results: This case was successfully managed by discontinuing topiramate and by starting anti-glaucoma medication. Intraocular pressure, acute transient myopia, and anterior chamber depth were normalized. Conclusions: It is important for clinicians to recognize these conditions and educate patients about these serious adverse effects when prescribing topiramate.
