(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.

(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.

(Turkish Ophthalmological Soc, 2009) Yener, Halil Ibrahim; Gul, Adem; Yasar, Tekin; Cinal, Adnan
Purpose: To report cataract cases along three generation in a large family. Introduce: Hereditary cataracts can be divided into two groups as congenital or developmental. Congenital cataracts can be seen with systemic diseases or as isolated in one third. Congenital cataract is still one of the most important treatable causes of blindness in childhood period. The proportion of blindness is 5-15/10 000 in developing countries and 1-4/10 000 in developed countries. The ratio of blindness related to cataract is 1-4/10 000 in developing versus 0,1-0,4/10 000 in developed countries. Case: A grandfather, his 10 children and five grandchildren were examined. Patients who have cataract were operated. All subjects were investigated in terms of systemic disases. Grandfather who was aphakic visited clinic for getting new glasses. Patient had operated in childhood period. He said that his two children were also operated in both eyes. We called other family members for ophthalmologic examination. We found posterior subcapsular cataract in four children and two grandchildren. None of these patients had systemic disases. conclusion: In cases of congenital or developmental cataracts, the relatives also must be examined and if needed intervention may be needed.
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.
Posterior Capsular Opacification in Preschool- and School-Age Patients After Pediatric Cataract Surgery Without Posterior Capsulotomy
(Turkish Ophthalmological Soc, 2016) Batur, Muhammed; Gul, Adem; Seven, Erbil; Can, Ertugrul; Yasar, Tekin
Objectives: We aimed to evaluate the development of posterior capsular opacification (PCO) in preschool-and school-age children with cataract who underwent cataract surgery without posterior capsulotomy and anterior vitrectomy. Materials and Methods: The records of 30 eyes of 21 patients who underwent pediatric cataract surgery and intraocular lens (IOL) implantation were retrospectively reviewed. Patients' age, PCO status and duration, need for neodymium-doped yttrium aluminium garnet (Nd: YAG) laser treatment based on coverage of visual axis, and follow-up period were recorded. Results: The mean age of the patients was 7.6 +/- 2.83 (4-12) years. Unilateral cataract surgery and IOL implantation were performed in 12 patients (57.14%) and bilateral cataract surgery and IOL implantation were performed in nine patients (42.86%). Average follow-up time was 17.7 +/- 22.67 (3-83) months. PCO developed in 21 eyes (70%) and covered the visual axis in 15 eyes (50%), which therefore required Nd: YAG laser posterior capsulotomy. The mean duration of postoperative PCO development was 8.91 +/- 18.7 months (1 week-71 months). Conclusion: We believe that with adequately experienced surgeons, performing both cataract surgery and posterior capsulotomy with anterior vitrectomy in the same session is appropriate for selected preschool-and school-age children with cataract.

(Turkish Ophthalmological Soc, 2010) Gul, Adem; Kilic, Adil; Yener, Halil Ibrahim; Demirok, Ahmet; Cinal, Adnan
Purpose: The aim of this study was, by analyzing data from uveitis patients living in Van province or referred from the surrounding provinces (i.e. Agri, Mus, Hakkari, Igdir and Bitlis), to reveal the profile of uveitis in that district. Material and Method: In this study, we retrospectively investigated 855 eyes of 678 uveitis patients who were examined and followed in Yuzuncu Yil University, Ophthalmology Department between 1996 and 2008. Results: The mean age of the patients was 29.86 +/- 16.01 (range 1-79) years. 403 (59.4%) were male and 275 (40.6%) patients were female. Monocular involvement was present in 501 (73.9%), while binocular involvement was observed in 177 (26.1%) patients. According to the involved area, 395 (58.3%) patients had anterior, 85 (12.5%) intermediate, 33 (4.9%) posterior and 165 (24.3%) patients had panuveitis. No accompanying findings were detected in 406 (59.9%) patients. The most frequent accompanying disease was Behcet's disease seen in 109 (16.1%) patients. Discussion: In this study, the profile of uveitis of Van and the surrounding provinces was revealed. We think that this study is important, because it reflects the profile of uveitis of the Eastern part and together with data obtained from the other parts of Turkey, it will contribute to the development of uveitis map of the country.

(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.
