İris renk spektrumuna göre ön ve arka segment parametrelerinin karşılaştırılması

Comparison of eye anterior and posterior segment parameters according to iris color Methods: 150 eyes of 150 patients who applied to Aksaray Training and Research Hospital between 2019-2020 were included in the study. 28 blue, 30 green, 29 light brown (light pigmentation), 31 medium brown (medium pigmentation) and 30 dark brown (heavy pigmentation)eyes, 5 groups of patients were included in the study. Biomicroscopy and fundus examination were performed on the patients. After measuring the refraction of the patients, corneal topography and optical biometry, Intraocular Pressure (IOP), Central Corneal Thickness (CCT), Anterior Chamber Depth (ACD), Anterior Chamber Angle (ACA), Lens Thickness (LK), Axial Length (AU) Retinal nerve fiber thickness (RSLK), central retinal thickness (CRC) and subfoveal choroidal thickness (SFKK) measurements were made with OCT. Results: The mean age of the patients was 33.4 ±5.5, 35.7±4.7, and 32.9 ±6.7 in patients with blue, green and brown eyes, respectively. There were 15 women and 13 men in the blueeyed group, 16 women and 14 men in the green-eyed group, and 47 men and 43 women in the brown-eyed group. In terms of anterior and posterior segment parameters, a difference was found between blue eyes and brown eyes in terms of CCT, ACD and LK (p=0.035, 0.004 and 0.012). A difference was found between blue eyes and green eyes in terms of ACD and LK (p=0.006 and 0.041). There was no significant difference between the anterior and posterior segment parameters of the green-eyed and brown-eyed patients. In addition, there was no difference between the groups in terms of other factors (p>0.05). As a result of the correlation analysis performed in terms of parameters according to iris pigmentation level, no positive or negative correlation was found with any parameter (p>0.05). Conclusions:When evaluating patients, it should be kept in mind that the normal values of some eye parameters may vary according to the differences in iris color.İris rengine göre göz anterior ve posterior segment parametrelerinin karşılaştırılması Yöntem: Aksaray Eğitim ve Araştırma Hastanesine 2019-2020 yılları arasında başvuran 150 hastasının 150 gözü çalışmaya dahil edildi.28 mavi, 30 yeşil, 29 hafif kahverengi(hafif pigmentasyon), 31 orta kahverengi(orta pigmentasyon) ve 30 koyu kahverengi(ağır pigmentasyon) göz olmak üzere 5 grup hasta çalışmaya alındı. Hastalara biyomikroskobik ve fundus muayenesi yapıldı. Hastaların refraksiyonları ölçüldükten sonra, korneal topografi ve optik biyometri ile Göz İçi Basıncı (GİB), Santral Korneal Kalınlık(SKK), Ön Kamara Derinliği(ÖKD), Ön Kamara açısı(ÖKA), Lens Kalınlığı(LK), Aksiyel Uzunluk(AU) ölçümleri ve OCT ile de retinal sinir lifi kalınlığı(RSLK), santral retinal kalınlık(SRK) ve subfoveal koroid kalınlık(SFKK) ölçümleri yapıldı. Bulgular: Hastaların yaş ortalamaları mavi, yeşil ve kahverengi gözlü hastalarda sırası ile 33.4 ±5.5, 35.7±4,7 ve 32,9 ± 6,7 idi. Mavi gözlü grupta 15 kadın 13 erkek, yeşil gözlü grupta 16 kadın 14 erkek ve kahverengi gözlü grupta 47 erkek 43 bayan yer aldı. Ön ve arka segment parametreleri açısından mavi göz ile kahverengi göz arasında SKK, ÖKD ve LK açısından fark saptandı (p=0.035, 0.004 ve 0.012). Mavi göz ile yeşil göz arasında ÖKD ve LK açısından fark saptandı (p=0.006 ve 0.041). Yeşil göz ve kahverengi gözlü hastaların ön ve arka segment parametreleri arasında da anlamlı bir farklılık saptanmadı. Ayrıca diğer faktörler açısından da gruplar arasında fark saptanmadı (p>0.05). İris pigmentasyon düzeyine göre parametreler açısından yapılan korelasyon analizi sonucu hiç bir parametre ile pozitif yada negatif korelasyon saptanmadı (p>0.05). Tartışma: Hastalar değerlendirilirken bazı göz parametrelerinin normal değerlerinin iris rengindeki farklılıklara göre değişiklik gösterebileceği akılda bulundurulmaldır

Wide-Field Retinal Imaging in Adults and Children

Wide-field retinal imaging has become an important standard of care imaging modality in many retinal disorders both in adults and children. The recently developed wide-field retinal imaging systems enable approximately 200° imaging of retina. In this chapter, we would like to review the use of wide-field retinal imaging in disorders such as retinal vascular diseases, uveal and retinal inflammatory diseases, intraocular tumors, peripheral retinal pathologies, and retinal disorders in children such as retinopathy of prematurity, familial exudative vitreoretinopathy, and Coats\u27 disease. Also, we would like to address the rapidly expanding role of peripheral retinal imaging in treating systemic diseases. The use of wide-field imaging technologies in screening, diagnosis, treatment, and documentation of retinal pathologies and the new information provided by wide-field angiography for retinal vascular diseases and macular problems will be discussed

Ophthalmic Needle Types and Suture Materials

Needle types and suture materials are basic subjects which every surgeon dealing with ophthalmic surgery should know. Tissue-compatible needle and suture selection as well as careful surgery will have doubtlessly a positive effect on the success. The purpose of this manuscript is to provide a detailed review of needle types and suture materials, as well as of the current developments, and also to make recommendations to the ophthalmic surgeons about appropriate choices of suture and needles.

Clinical characteristics and surgical results in patients with sensory heterotopia

Amaç: Sensoryel heterotropyalarda görülen kayma tiplerini ve etyolojilerini belirlemek, cerrahi sonuçları değerlendirmek. Gereç ve Yöntem: Çalışmada sensoryel heterotropya tanısıyla opere edilmiş, ortalama yaşları 20,7±7,95yıl (8-36) olan 12’si kadın 15’i erkek 27 hastanın kayıtları retrospektif ola- rak incelendi. Bütün olguların kayma tipi, etyolojileri, cerrrahi yaşı, refraksiyon değerleri, cerrahi öncesi ve sonrası görme keskinliği ile kayma dereceleri, biyomikroskopik ve fundos- kopik bulguları kaydedildi. Ortalama 13,29±4,12 ay (7-20) takip edilen hastaların kayma de- recesi son kontrolde ±10 PD (prizm dioptri) aralığında ise başarılı kabul edildi. Bulgular: Olguların 12’inde (%44,4) ezotropya (ET), 15’inde (%55,6) ekzotropya (XT) mevcuttu. Tüm olgularda etyolojiler incelendiğinde 17’sinde (%63) anizometropi, 5’inde (%18,5) travma ve 5’inde (%18,5) doğumsal nedenler saptandı. Olguların kayma olan gözle- rindeki görme keskinliği ışık persepsiyonu (-) ile 0,7 logMAR arasında değişmekteydi. Cerrahi sonrası hiçbir olguda takip süresince görme keskinliğinde artış izlenmedi. Tüm olgularda cer- rahi öncesi ortalama kayma derecesi 46,44±20,44 PD iken cerrahi sonrası 9,11±2,56 PD bu- lundu. Tüm olgularda cerrahi başarı oranı %77,8 iken ET grubunda %75 XT grubunda ise %80 bulundu. Sonuç: Sensoryel heterotropyalarda kozmetik açıdan oldukça tatminkar cerrahi sonuçlar elde edilmesine rağmen, görme fonksiyonu sabit kalmaktadır.Aim: To determine the deviation type and etiology in sensory heterotropia and evaluate the results of surgery. Material and Method: The records of 27 patients operated for sensory heterotropia (12 fe- male, 15 male) whose mean age was 20.7±7.95 (range:8-36) years were evaluated retrospec- tively. Deviation types, etiologies, age at surgery, refractive measurements, preoperative/post- operative visual acuity and deviation amounts, biomicroscopic and fundoscopic findings were noted in all cases. The mean follow-up time was 13.29±4.12 months (range:7-20) and devia- tion in ±10 prism diopters (PD) in the last visit was considered as success. Results: Twelve cases (44.4%) had esotropia (ET) and 15 cases (55.6%) had exotropia (XT). Etiologies in all cases examined were as follows; anisometropia in 17 (63%), trauma in 5 (18,5%) and congenital causes in 5 (18.5%). The visual acuity of the squinting eyes ranged from no light perception to 0.7 logMAR. None of the cases had increase in visual acuity dur- ing follow-up after surgery. The mean preoperative deviation and mean postoperative devia- tion were 46.44±20.44 PD and 9.11±2.56 PD, respectively. The surgical success rate was found to be 77.8 % for all cases, 75% for the ET group and 80% for the XT group. Conclusion: In sensorial heterotropia although cosmetically favourable surgical results are obtained, visual function remains stable

Coexistence of peripheral retinal diseases with macular hole

Amaç: Maküler hol hastalarında periferik retinanın incelenmesi ile eşlik eden retinal yırtık, retinal delik ve lattice dejenerasyonu sıklığını araştırmaktır. Gereç ve Yöntem: Eskişehir Osmangazi Üniversitesi Göz Hastalıkları Anabilim Dalı’nda 2008-2018 yılları arasında maküler hol tanısı ile pars plana vitrektomi cerrahisi yapılan hastaların dosyaları retrospektif olarak incelendi. Cerrahi sırasında periferik retina muayenesi yapılmış, primer maküler hol tanısı olan 106 hasta çalışmaya dahil edildi. Maküler hol ile birlikte olan retinal yırtık, retinal delik ve lattice dejenerasyonu sıklığı araştırıldı. Bulgular: Maküler hol cerrahisi yapılmış 106 hastada periferik retina incelemesi sonucu 3 (%2,8) hastada retinal yırtık, 4 (%3,8) hastada retinal delik ve 10 (%9,4) hastada lattice dejenerasyonu görüldüğü saptandı. Bir hastada retinal delik ve lattice dejenerasyonunun birlikte görüldüğü tespit edildi. Sonuç: Çalışmamızda maküler hol hastalarında benzer şekilde vitreoretinal çekinti sonucu oluştuğu düşünülen retinal yırtık ve delik sıklığı toplum ile benzer sıklıkta saptanmıştır. Bu sonuç vitreusun bu hastalıklar açısından anterior ve posteriorda farklı patolojiler içerebileceğini gösterebilir.Objectives: To investigate the frequency of retinal tear, retinal hole, and lattice degeneration in peripheral retinal examination of patients with macular hole. Materials and Methods: The files of patients who underwent pars plana vitrectomy surgery with a diagnosis of macular hole at Eskişehir Osmangazi University Department of Ophthalmology between 2008 and 2018 were retrospectively analyzed. A total of 106 patients with primary macular hole who underwent peripheral retinal examination were included in the study. The frequency of retinal tears, holes, and lattice degeneration associated with macular hole was investigated. Results: Peripheral retinal examination of 106 patients who underwent macular hole surgery revealed retinal tear in 3 patients (2.8%), retinal hole in 4 patients (3.8%), and lattice degeneration in 10 patients (9.4%). Retinal hole and lattice degeneration were observed concomitantly in 1 patient. Conclusion: This study showed that patients with macular hole have concomitant retinal tears and holes, which are also thought to arise due to vitreoretinal traction, at a frequency similar to that in the general population. This result suggests that both the anterior and posterior vitreous may have different pathologies at the same time related to these diseases

Comparison of Different Types of Complications in the Phacoemulsification Surgery Learning Curve According to Number of Operations Performed

OBJECTIVES: To compare the differences in intraoperative complications rates by the number of resident-performed sequential phacoemulsification surgeries. MATERIALS AND METHODS: Preoperative and postoperative ophthalmological examination records and intraoperative data of 180 eyes of 140 patients who underwent cataract surgery by two residents between November 2009 and February 2012 were analyzed retrospectively. The data of 180 eyes were separated into 3 groups based on the number of operations performed: Group A (first 1-60 eyes), group B (61-120 eyes) and group C (last 121-180 eyes). The number of direct supervisor interventions and the rates of different types of complications were compared between the three groups. RESULTS: The number of direct supervisor interventions was 45, 35 and 19 in group A, B and C, respectively. The number of complications anterior to the iris plane was 3, 4 and 12 in group A, B and C, respectively. The difference in the rate of complications between group B and C was statistically significant (p=0.029). The number of complications posterior to the iris plane was 6, 14 and 3 in group A, B and C, respectively. The difference in the rate of complications between the groups was statistically significant (p=0.042, p=0.004). CONCLUSION: This study provides insight into which types of complications might arise during the phacoemulsification training period. The trends in the rates of different complication types in clinics may be analyzed, and this analysis may be used to improve and modify phacoemulsification training programmes according to the needs of residents
