Purpose: To investigate the possible association between acquired ectropion uveae and blunt trauma to the eye. We present 3 cases of acquired ectropion uveae that occurred after blunt trauma to the eye. There are no previously published data on possible association of these conditions. Methods: A retrospective review was conducted of patients with ectropion uveae and eye injury at University Eye Hospital over a 10-year period (2006-2016). We analyzed medical records and clinical findings. Results: Three eyes of 3 male patients with ocular trauma and ectropion uveae, ages 71, 68, and 5 years, were reviewed. The period between the eye injury and the diagnosis of ectropion uveae ranged from 10 to 36 months. All 3 eyes developed clinical evidence of secondary glaucoma with moderately to severely elevated intraocular pressure (IOP) (ranging from 29 to 48 mm Hg). Surgical treatment (trabeculectomy) was needed in 2 cases in order to control secondary glaucoma and conservative treatment was sufficient in 1 case. Mean patient follow-up was 19.3 ± 4.6 months. Conclusions: Trauma can be considered as a cause of acquired ectropion uveae. Acquired ectropion uveae following eye trauma may be associated with significant increase in IOP. All patients in our series had secondary glaucoma and 2 of 3 required surgical treatment for IOP control. © 2016 Wichtig Publishing.

Purpose: To describe the role of optical coherence tomography (OCT) in detecting subclinical choroidal inflammation and early diagnosis of macular complications in chronic Vogt-Koyanagi-Harada (VKH) disease with sunset glow fundus. Methods: Retrospective observational study. Clinical features, OCT images, treatment, and visual outcome were analyzed. Results: Fourteen patients (9 females and 5 males) were included in the study. Mean age was 39 years (range 7–67 years). Mean duration of disease was 5.25 years (range 1–15 years). Anterior uveitis was seen in 14 eyes (52%). Fundus examination showed sunset glow fundus in all patients with no obvious macular pathology. OCT showed macular edema in 16 eyes (59%), choroidal neovascular membrane in 8 eyes (30%), and macular hole in 3 eyes (11%). Conclusion: OCT should be regularly used to detect subclinical inflammation and early macular complications in chronic VKH disease where sunset glow fundus may delay the clinical diagnosis thus causing permanent damage. © 2020 Taylor & Francis Group, LLC.

Purpose: Viral agents are the most common cause of infectious anterior uveitis worldwide. The purpose of this review is to analyze the frequency, gender and racial differences of viral anterior uveitis (VAU) in various populations. Methods: Systematized literature review of epidemiological reports of VAU cited in PubMed, EMBASE and the Cochrane Library database published until June 30th, 2020. Results: A total of 12 clinical studies on epidemiology of definite VAU and 36 clinical studies of presumed VAU were identified. Members of Herpesviridae family represent the most common causes of VAU. Other less frequently reported causes, such as rubella and endemic viruses (HTLV-1, Chikungunya, Dengue, Ebola, Zika virus) were also analyzed. Conclusion: HSV, VZV are prevalent worldwide. CMV is more frequent in Asia, and rubella in the West. However, due to globalization and air travel, HTLV-1, Chikungunya, Dengue and Ebola may become important causes of VAU across the world. © 2020 Taylor & Francis Group, LLC.

Aim: To evaluate glutathione transferase theta 1 and mu 1 (GSTT1 and GSTM1) polymorphisms as determinants of primary open angle glaucoma (POAG) risk, independently or in combination with cigarette smoking, hypertension and diabetes mellitus. ● Methods: A case-control study with 102 POAG patients and 202 age and gender-matched controls was carried out. Multiplex-polymerase chain reaction method was used for the analysis of GSTM1 and GSTT1 polymorphisms. The differences between two groups were tested by the t-test or χ2test. Logistic regression analysis was used for assessing the risk for disease development. ● Results: The presence of GSTM1-null genotype did not contribute independently towards the risk of POAG. However, individuals with GSTT1-active genotype were at almost two-fold increased risk to develop glaucoma (P=0.044) which increased up to 4.36 when combined with GSTM1-null carriers (P=0.024). When glutathione transferase (GST) genotypes were analyzed in association with cigarette smoking, hypertension and diabetes, only carriers of GSTT1-active genotype had significantly increased risk of POAG development in comparison with GSTT1-null genotype individuals with no history of smoking, hypertension and diabetes, respectively (OR=3.52, P=0.003; OR=10.02, P<0.001; OR=4.53, P=0.002). ● Conclusion: The results obtained indicate that both GSTM1-null and GSTT1-active genotypes are associated with increased POAG risk among smokers, suggesting potential gene-environment interaction in glaucoma development. © 2018, International Journal of Ophthalmology (c/o Editorial Office).

The aim of this survey was to estimate the incidence of primary CNS tumors among children aged 0-14 in Belgrade during the period 1991-2004. Incidence rates were age-adjusted according to the world standard population. The average age-adjusted incidence rates were 3.4/100,000 for boys, 2.4/100,000 for girls, and 2.9/100,000 for both genders. There was a nonsignificant tendency toward increased CNS tumor incidence (y = 2.547 + 0.052x, p =.549). The age-specific incidence rates were 3.0/100,000 (0-4 years), 2.2/100,000 (5-9 years), and 3.8/100,000 (10-14 years). Among the population aged between 0 and 14, the cumulative probability of acquiring primary CNS tumors was 1 per 1961 for boys and 1 per 2778 for girls. Astrocytoma was the most common pathohistological type of primary CNS tumors accounting for 41.5% of cases. © Informa Healthcare USA, Inc.

Purpose: To study the clinical features, causative factors and treatment outcomes in patients with infectious scleritis seen in India. Methods: A retrospective study of all patients examined at a tertiary care center between August 2012 and March 2021. Results: Forty-five patients (45 eyes; mean age 52.7 ± 17.5 years) were included in the study. The mean duration of symptoms was 3.1 ± 4.4 months. Inciting factors were found in 53.3% (injury: 33.3%; ocular surgery: 20.0%). The scleritis was predominantly anterior (97.8%), with multiple lesions in 40.0%, a solitary lesion in 31.1%, and diffuse in 28.9%. Associated features included uveitis (51.1%), keratitis (37.8%), hypopyon (15.6%), and endophthalmitis (6.7%). Causative organisms included bacteria (53.3%), fungi (35.6%), and presumed herpes virus (11.1%). All patients were treated with antimicrobial agents along with systemic corticosteroids where indicated. Surgical treatment included scleral debridement (37.8%), patch grafts (4.4%), and penetrating keratoplasty (2.2%). Complete resolution of scleritis was seen in 86.7%, with a mean duration of therapy of 2.9 ± 2.5 months. The mean follow-up was 8.3 ± 14.3 months. 51.1% of patients lost functional vision (<6/60). Causes of decreased vision included corneal scar, cataract, macular scar, glaucomatous optic atrophy, and phthisis bulbi. On bivariate analysis, poor visual acuity at presentation was associated with a worse visual outcome (p = 0.02). Other risk factors included necrotizing scleritis, multifocal scleritis, the presence of keratitis and uveitis. Conclusion: In our study, infectious scleritis resulted from bacterial and fungal infections. The scleritis resolved in most subjects, however, vision loss was frequent due to infection-related complications. © 2024 Taylor & Francis Group, LLC.

Backgrounds and Objectives: To analyze the influence of multiple anti-VEGF intravitreal injections for exudative age-related macular degeneration on the thickness of peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell-inner plexiform layer (GC + IPL) using spectral domain optical coherence tomography (SD-OCT). Materials and Methods: A prospective interventional study of consecutive patients treated with intravitreal bevacizumab (IVB) was performed. Average and sectorial values of RNFL and GC + IPL thickness were recorded using Cirrus SD-OCT at 0, 6, 12, and 24 months. Patients suffering from any ocular disease that could affect RNFL or GC + IPL thickness were excluded. Results: A total of 135 patients (70 women and 65 men, aged 65 ± 15 years) were included. The average number of injections per patient was 12.4 ± 2.4. Average RNFL and GC + IPL thickness prior to the first injection (87.6 ± 12.2 and 47.2 ± 15.5 respectively), and after 24-month follow-up (86.2 ± 12.6 and 46.7 ± 11.9 respectively) did not differ significantly (p > 0.05). There was a significant decrease in GC2, GC5 segments, and minimum GC + IPL thickness. Conclusion: Repeated anti-VEGF treatment did not cause significant changes in the thickness of RNFL and GC + IPL layers over a period of 24 months. The detected decrease in GC2 and GC5 sectors, as well as in minimum GC + IPL thickness, could be a sign of ganglion cell damage induced by the treatment or could occur during the natural course of the disease. © 2023 by the authors.

Introduction: Uveitic macular edema (UME) is a significant cause of visual impairment in all uveitis types. Methods: Reports that were cited in the MEDLINE database, that analyzed the effectiveness of biologics for UME in at least five patients, with a minimum follow-up of 3 months, published prior to April 1, 2019 were included. Reports that did not compare UME findings before and after the therapy, using either OCT or fluorescein angiography, were excluded. Results: Case series that analyzed the efficacy of intravitreal anti-VEGF agents showed modest, short-term benefit. Studies that investigated systemic anti-TNF agents in patients with noninfectious uveitis reported a therapeutic effect on UME. Anti-IL-6 antibodies have shown promising results for most severe cases of noninfectious UME. Interferon represents an option for patients with persistent UME in infectious and noninfectious uveitis. Conclusion: Multicenter, randomized controlled trials are needed to assess the effectiveness of each group of biologic agents in sufficient number of patients. © 2020 Taylor & Francis Group, LLC.

Introduction. Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is character-ized by necrotizing granulomatous inflammation in various tissues, including blood vessels, but primarily in the respira-tory tract and kidneys. Clinical manifestations can be di-verse, including inflammation of the eye and adnexa. Optic neuritis is a very rare ophthalmological manifestation of GPA, not previously described in a teenager. Case report. We presented a case of a 16-year-old girl with a rare extrap-ulmonary manifestation of GPA. The girl had a previous history of GPA and complained of a sudden blurred vision in the left eye. She was promptly referred to an ophthalmol-ogist who noted a decreased visual acuity of 20/400 in the left eye. Colour vision was impaired in the spectrum of red colour. Clinical examination revealed normal anterior seg-ment findings. On ophthalmoscopy, the left optic nerve oe-dema was noted. Urgent computed tomography of the left orbit showed a soft tissue mass around the optic nerve in the apex of the orbit. Magnetic resonance imaging con-firmed the diagnosis of optic perineuritis. After pulse doses of methylprednisolone, the girl achieved complete resolu-tion of vision in the left eye. Conclusion. If untreated, in-flammation of the optic nerve can lead to a permanent loss of vision. Prompt diagnostic and adequate treatment of pa-tients with GPA is needed in order to prevent vision-threatening complications and control the systemic disease. © 2021 Inst. Sci. inf., Univ.

Introduction: Sympathetic ophthalmia (SO) is rare, bilateral granulomatous panuveitis that typically occurs following penetrating or perforating ocular trauma or surgery. This review aims to provide an update on the etiopathogenesis, clinical presentations, diagnosis and treatment of SO. Methods: Reports cited in MEDLINE database, that analyzed SO in at least 5 patients, published prior to December 1st, 2021 were included. Results: Initially, SO was associated with penetrating ocular trauma, however, various studies reported an increased incidence of SO after surgical procedures including vitreoretinal surgeries. Multimodal imaging including fluorescein and indocyanine green angiography, optical coherence tomography (OCT) and OCT angiography have added further insights into the understanding of SO. While pulse dose corticosteroids & immunosuppressive drugs are still the treatment of choice, TNF-α blockers & other biologic drugs represent new promising agents. Conclusion: There is a growing pool of evidence in understanding the pathogenesis of SO. Novel treatment options have provided better prognosis for this potentially blinding condition. © 2022 Taylor & Francis Group, LLC.

Age-related macular degeneration (AMD) is a complex, degenerative and progressive disease involving the multiple genetic and environmental factors that can result in severe visual loss. The etiology of AMD is not well understood. Many theories exist and feature mechanisms of oxidative stress, atherosclerotic-like changes, genetic predisposition and inflammation. The most recent clinical studies appointed to a great role of inflammation and C-reactive protein (CRP) in the pathogenesis of AMD. There is a large body of evidence indicating the association of CRP with endothelial dysfunction, oxidative stress and production of reactive oxygen species (ROS), as well as with lipid status disorder in AMD patients. According to recent studies, CRP is definitely not only the inflammatory marker but also a mediator of development of the vascular disorders in the retinal circulation. The results obtained from the present studies may help our understanding the pathogenesis of the retinal vascular disease associated with high levels of CRP.
