The congress held in Brussels in 1902 "amelioration of the life standards of the blinds" and the evaluation of an ophthalmologist attended from Istanbul

Körlerin eğitimi ve öğretimiyle ilgili çabalar 18. yüzyıl sonlarına doğru başlamıştır. Bu sosyal sorunun çözümü için harcanan çabaların önemli bir aşaması 1902 yılında Brüksel’de yapılan “Körlerin Durumlarının Düzeltilmesi Kongresi” dir. Adı geçen kongrede tartışılan konular, Osmanlı Devleti delegesi Dr.Esat Bey tarafından Servet-i Fünun dergisinin 11 Eylül 1329 (miladi 24 Eylül 1903) tarihli, 648 numaralı nüshasında yayınlanmıştır. Bu kongrede yedi ana konu tartışılmıştır. Esat Bey, adı geçen dergide kongre tartışma konularının ayrıntılarının yanında körlerin eğitimiyle ilgili resimleri de sunmuştur. Kongredeki bir sorunun cevabı olarak, İstanbul’da icra ettiği dokuz yıllık göz hekimliği sonucunda, 30 bin hasta üzerinde düzenlediği istatistiği ve kişisel deneyimleriyle görüşlerini ayrıntılarıyla vermiştir. Bu kongreden çıkan sonuçlara dayanarak, Türkiye’deki Körlerin eğitim ve öğretimiyle ilgili çabalar başlatılmıştır. Kongre, Darülaceze’de bir şube kurulması halinde, uygun şartlarda, Belçika Körler Okulundan bir öğretmenin gönderileceğini vaad etmiştir. Esat Bey, bu kongrenin sonuç bildirgesiyle beraber hazırladığı geniş raporu, körler için bir eğitim okulu açılması gereğini, gerekçeleriyle beraber devlet hiyerarşisi kanalıyla Sultan II. Abdülhamit’e arz etmiştir. Yıllar içinde, Darülacezede körlere yönelik bir şube açılması sağlanmış, Acıbadem semtinde körler ile sağır ve dilsizlerin eğitimine yönelik bir okulun inşası için geniş bir arsa tahsis edilmiş, ancak, padişahın tahttan indirilmesi, seferberlik ve ardı ardına gelen savaşlar nedeniyle bu girişimler sonuçsuz kalmıştır. Bu çalışmada, kongre ayrıntıları Osmanlıca’dan Türkçeye aktarılmış, sadeleştirilerek paylaşılmıştır. Ayrıca, körlerin eğitimiyle ilgili gelişmelerin kısa tarihçesi sunulmuş, konu ayrıntıları verildikten sonra, bu kongrenin etkisiyle ülkemizde yapılan ilk girişimler tarihsel süreç içinde tartışılmıştır.The educational attempts for blinds started aproximately at the end of the 18th century. An important step of these attempts was “The Congress for amelioration of the life standards of blinds” that had been held in Brussels in 1902. The topics discussed in the above mentioned congress were published by Dr.Esat Bey, the representative of The Ottoman Empire, in the 11 September 1329 (24 September 1903) dated, no 648 offprint of the “Servet-i Fünun” magazine. Dr.Esat Bey also published some photographs about the education of blinds in the same newspaper. While responding to a question in the congress, he presented his personal experience and statistical results based on 30000 patients that he examined as an ophthalmologist in Istanbul in a duration of 9 years. The studies directed to the education of blinds were initiated after the experience obtained from this congress. The Commitee of the Congress accepted to send a teacher from the School for Blinds of Brussels if a branch should be opened in Darülaceze. Dr.Esat Bey prepared a report including the results obtained from the Congress and had it presented to Sultan II.Abdülhamit with the aim of creating a school for blinds. A school was opened in Darülaceze and a land in Acıbadem was spared for the education of blinds, deaf and dumbs. But these could not be realized as the Sultan was taken down from throne and continuing wars. In this study the details about the congress were translated from Ottoman language to Turkish and presented after purification. A brief history about the beginning attempts of the education of the blinds and its development in Turkey with the effect of Brussels congress are discussed

Current roles of artificial intelligence in ophthalmology

Artificial intelligence (AI) studies are increasingly reporting successful results in the diagnosis and prognosis prediction of ophthalmological diseases as well as systemic disorders. The goal of this review is to detail how AI can be utilized in making diagnostic predictions to enhance the clinical setting. It is crucial to keep improving methods that emphasize clarity in AI models. This makes it possible to evaluate the information obtained from ocular imaging and easily incorporate it into therapeutic decision-making procedures. This will contribute to the wider acceptance and adoption of AI-based ocular imaging in healthcare settings combining advanced machine learning and deep learning techniques with new developments. Multiple studies were reviewed and evaluated, including AI-based algorithms, retinal images, fundus and optic nerve head (ONH) photographs, and extensive expert reviews. In these studies, carried out in various countries and laboratories of the world, it is seen those complex diagnoses, which can be detected systemic diseases from ophthalmological images, can be made much faster and with higher predictability, accuracy, sensitivity, and specificity, in addition to ophthalmological diseases, by comparing large numbers of images and teaching them to the computer. It is now clear that it can be taken advantage of AI to achieve diagnostic certainty. Collaboration between the fields of medicine and engineering foresees promising advances in improving the predictive accuracy and precision of future medical diagnoses achieved by training machines with this information. However, it is important to keep in mind that each new development requires new additions or updates to various social, psychological, ethical, and legal regulations

YKL-40 is a local marker for inflammation in patients with pseudoexfoliation syndrome

Purpose: To investigate the YKL-40, as a marker of inflammation, in aqueous humor and serum of cataract patients with and without pseudoexfoliation syndrome (PEX). Methods: Aqueous humor and serum samples were obtained from 44 patients who underwent phacoemulsification surgery. All patients were divided into two groups: PEX (n = 24) and control (n = 20). YKL-40 levels were measured with enzyme-linked immunosorbent assay (ELISA). The differences between the groups were assessed by using Chi-square and independent sample t-tests. The Pearson correlation coefficient was used to evaluate the correlation between variables. Results: There was a significant difference between the mean YKL-40 levels in the aqueous humor of PEX group (112.0 ± 35.8 ng/mL) and control subjects (88.2 ± 30.6 ng/mL) (P = 0.025). However, the difference between the mean YKL-40 levels in the serum of PEX group (53.5 ± 29.1 ng/mL) and control subjects (44.6 ± 30.2 ng/mL) was non-significant (P = 0.326). The correlation between aqueous humor and serum YKL-40 concentrations was significant in both the groups (r = 0.833, P < 0.001; r = 0.840, P < 0.001, respectively). Conclusions: Increased aqueous humor levels of YKL-40 demonstrate that it is local, but not a systemic marker for inflammation in patients with PEX. © 2018, The Royal College of Ophthalmologists

Anti-inflammatory and ultrastructural effects of Turkish propolis in a rat model of endotoxin-induced uveitis

Introduction. Experimental animal models of acute uveitis, an inflammatory eye disease, can be established via endotoxin-induced inflammation. Propolis, a natural substance collected by honeybees from buds and tree exudates, has antioxidant, antibacterial, antiviral, and anti-inflammatory effects. We investigated the effects of propolis, obtained from the Sakarya province of Turkey, on endotoxin-induced uveitis using immunohistochemical, ultrastructural, and biochemical approaches. Material and methods. Male Wistar albino rats (n = 6/group) received intraperitoneal (ip) lipopolysaccharide (LPS) endotoxin (150 μg/kg) followed by aqueous extract of propolis (50 mg/kg ip) or vehicle; two additional groups received either saline (control) or propolis only. After 24 h, aqueous humor (AH) was collected from both eyes of each animal for analysis of tumor necrosis factor-α (TNF-α) and hypoxia-inducible factor-1α (HIF-1α). Right eyeballs were paraffin-embedded for immunohistochemical staining of nuclear factor κB (NF-κB)/p65 and left eyeballs were araldite-embedded for ultrastructural analysis. Results. Treatment of LPS-induced uveitis with propolis significantly reduced ciliary body NF-κB/p65 immunoreactivity and AH levels of HIF-1α and TNF-α. Ultrastructural analysis showed fewer vacuoles and reduced mitochondrial degeneration in the retinal pigment epithelium, as compared to the uveitis group. The intercellular spaces of the inner nuclear layer and outer limiting membrane were comparable with those of the control group; no polymorphonuclear cells or stasis was observed in intravascular or extravascular spaces. Conclusions. This is the first report demonstrating an anti-inflammatory effect of Turkish propolis in a rat model of LPS-induced acute uveitis, suggesting a therapeutic potential of propolis for the treatment of inflammatory ophthalmic diseases

The evaluation of the effect of pilocarpine induced accomodation on anterior chamber depth in pseudophakic eyes using magnetic resonance imaging

Amaç: Tek parçalı ve 3 parçalı hidrofobik akrilik göz içi lensi (GİL) implante edilmiş hastalarda, siklopentolat hidroklorür (HCI) ve pilokarpin HCI’nin ön kamera derinliğine (ÖKD) etkisinin karşılaştırılması. Gereç ve Yöntem: Komplikasyonsuz saydam kornea kesili fakoemülsifikasyon ve GİL implantasyonu yapılmış 19 hastanın 19 gözü değerlendirildi. Hastaların 9’una (grup 1) tek parçalı (AcrySof SA60AT, Alcon) ve 10’una da (grup 2) 3 parçalı (AcrySof MA60BM, Alcon) katlanabilir, hidrofobik akrilik GİL implante edilmişti. Hastaların opere edilen gözlerinin ÖKD’ leri üç gün arayla, sırasıyla pilokarpin HCI %2 ve siklopentolat HCI %1 damlatıldıktan sonra T2 ağırlıklı manyetik rezonans görüntüleri kullanılarak aksiyel ve sagittal planda hesaplandı. Cerrahi ile manyetik rezonans görüntüleme arasındaki ortalama süre grup 1’de 16,1, grup 2’de 13.7 aydı. Wilcoxin ve Mann-Whitney U testleri ile grup içi ve gruplar arası kıyaslamalar yapıldı. Bulgular: Pilokarpin HCI sonrası ortalama ÖKD, grup 1 de 3,67 ± 0,39 mm ve grup 2’de 4,06 ± 0,24 mm idi (p=0,35). Siklopentolat HCI sonrası ÖKD, grup 1’de 3,70±0,37 mm ve grup 2’de 4,01 ± 0,20 mm idi (p=0,53). Pilokarpin HCI ve siklopentolat HCI sonrası ÖKD arasındaki ortalama fark, grup 1 ve grup 2’de, sırasıyla 0,027±0,087 mm ve -0,045±0,10 mm idi (p>0,05). Sonuç: Fakoemülsifikasyon ve GİL implantasyonu sonrası uzun dönemde siklopentolat HCI ve pilokarpin HCI, tek parçalı ve üç parçalı hidrofobik akrilik GİL’de anlamlı bir aksiyel harekete neden olmamaktadır.Aim: To compare the effect of cyclopentolate hydrochloride (HCI) and pilocarpine HCI on anterior chamber depth (ACD) between single-piece and three-piece hydrophobic acrylic intraocular lens (IOL) after uneventful phacoemulsification using magnetic resonance imaging. Material and Method: Nineteen eyes of 19 patients who had uneventful sutureless clear corneal phacoemulsification with IOL implantation were included in the study. Nine eyes (group 1) had single-piece (AcrySof SA60AT, Alcon) and 10 eyes (group 2) had three-piece (AcrySof MA60BM, Alcon) foldable hydrophobic acrylic IOL. ACD was measured in the axial and sagittal T2 weighted magnetic resonance images after 2% pilocarpine HCI installation. Three days later, the same procedure was repeated after 1% cyclopentolate HCI installation. The average time interval between surgery and MR imaging was 16.1&plusmn;0.9 months in group 1 and 13.7&plusmn;0.8 months in group 2. Statistical analysis were performed with the Mann-Whitney U test between groups and the Wilcoxon signed rank test within them. Results: The average ACD after pilocarpine HCI instillation was 3.67&plusmn;0.39 mm and 4.06 &plusmn; 0.24 mm in group 1 and group 2, respectively (p=0.35). The average ACD after cyclopentolate HCI instillation was 3.70&plusmn;0.37 mm and 4.01&plusmn;0.20 mm in group 1 and group 2, respectively (p=0.53). The difference between the average ACD after pilocarpine HCI and cyclopentolate HCI instillations were 0.027&plusmn;0.087 mm and -0.045 &plusmn; 0.10 mm in group 1 and group 2, respectively (p&gt;0.05). Conclusion: Pilocarpine HCI and cyclopentolate HCI do not cause a significant axial shift on single-piece and three-piece hydrophobic acrylic IOL in the late period after phacoemulsification and IOL implantation

Anterior Transposition of the Inferior Oblique Muscle in the Treatment of Unilateral Superior Oblique Palsy

Purpose: To determine whether unilateral inferior oblique anterior transposition alone could be an effective procedure for treating superior oblique palsy with inferior oblique overaction. Methods: The records of 38 patients who underwent unilateral inferior oblique anterior transposition for unilateral superior oblique palsy with inferior oblique overaction were evaluated. A comprehensive ocular examination including best-corrected visual acuity measurements, ductions, versions, and deviations at near and distance, head tilt test, abnormal head position, dilated fundus examination, and Titmus test was performed prior to and after surgery. Results: The mean patient age was 29 years, the mean follow-up was 32 months, the mean preoperative hypertropia in primary position was 14.29 +/- 7.7 prism diopters (PD), and the mean inferior oblique overaction was 3.63 +/- 0.67. Anterior transposition of the inferior oblique muscle was effective across a wide range of preoperative primary position hypertropia (4 to 35 PD) with a mean reduction in postoperative hypertropia of 12 PD. Inferior oblique overaction was reduced in all patients. No patient demonstrated postoperative primary position hypotropia. Surgery improved stereoacuity nearly two units using the Titmus stereoacuity scale. Conclusion: Anterior transposition of the inferior oblique muscle is effective in correcting inferior oblique overaction and primary position hypertropia in the treatment of unilateral superior oblique palsy
