Ocular Adnexal Lymphoma: Epidemiology and Clinical Characteristics

The aim of the study is to emphasize the frequency, clinical presentation, histopathologic features and TNM staging for each type of ocular adnexal lymphoma (OAL), and investigating treatment results and prognosis in our region. A retrospective review of 54 patients treated for primary and secondary OAL between Jan 2012 and Jan 2019 was made. Epidemiologic data, clinical characteristics of the tumor and recurrence free survival rates were evaluated. Patients with ocular adnexal lymphoma included 27 (50%) women and 27 (50%) men, with a mean age of 60.38 +/- 15.36 (range: 18-93) years at the time of presentation. Mean follow-up time was 40.88 +/- 20.75 (range 1-84) months. Histopathological diagnosis was extranodal marginal zone lymphoma in 75.9%, diffuse large B-cell lymphoma in 14.8%, chronic lymphocytic leukemia/small lymphocytic lymphoma in 5.6%, mantle cell lymphoma in 1.9% and follicular cell lymphoma in 1.9% of patients. Among 54 patients with OAL 66.7% had orbital, 22.2% had conjunctival, 5.6% had orbital plus conjunctival, 3.7% had orbital plus conjunctival and choroidal, 1.9% had conjunctival plus choroidal involvement. No recurrences were observed in 87.1% of patients during their follow-up. Our data indicates patient epidemiologic data, TNM staging, most common clinical presentation and location of primary and secondary OALs from a single center

Demographics and etiologic characteristics of non-glaucomatous optic atrophy: a single-center cross-sectional study from Turkey

Background Optic atrophy is an end-stage pathology of optic nerve diseases that is characterized by optic nerve pallor and vision loss. Because of its sight-threatening effects, understanding its epidemiology and etiology is crucial. In this study, we aimed to determine the epidemiologic features of optic nerve pathologies which lead to optic atrophy. Methods This is a cross-sectional study in which, medical records of optic atrophy patients who were followed up in our clinic between 1999 and 2020 were evaluated. Three hundred and sixty eyes of 226 patients were included in the study. Demographic data were received from the patients' files. Patients with glaucomatous optic atrophy, consecutive optic atrophy and patients with less than a year follow-up were excluded from the study. Results The most frequent reason of optic atrophy was central nervous system diseases (27.43%) followed by secondary non-arteritic ischemic optic neuropathy (26.99%). The most frequent etiology of optic atrophy was non-arteritic ischemic optic neuropathy in males and central nerve system-related pathologies in females. The highest presentation age (mean 63.6 +/- 17.85 years) was observed in arteritic ischemic optic neuropathy and central nerve system-related optic atrophy had the lowest presentation age (median 14 years, IQR [34]). Conclusion Central nerve system diseases and non-arteritic ischemic optic neuropathies were the most common causes of non-glaucomatous and non-consecutive optic atrophy in Turkey. Better understanding of underlying etiologies of optic atrophy may lead us to take precautions timely for irreversible optic nerve dysfunction which is an important reason of blindness

Evaluation of macular microvascular structure with optical coherence tomography angiography in children with history of treatment for retinopathy of prematurity

Purpose To compare macula vascular parameters in optical coherence tomography angiography (OCTA) of children with history of retinopathy of prematurity (ROP) who were treated with laser photocoagulation (LPC) or intravitreal Bevacizumab therapy

The asymptomatic ocular surface reservoir of coronavirus disease-19 in infants and retinopathy of prematurity screening during the pandemic

PURPOSE: This study aimed to evaluate the incidence of conjunctival and pharyngeal swab sample positivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in asymptomatic preterm and term infants. We aimed to detect asymptomatic carrier potential in infants. MATERIALS AND METHODS: Patients screened for retinopathy of prematurity (ROP) at our clinic between January and June 2021 were recruited for this study. For all study cases, the previous history of possible exposure or contact with SARS-CoV-2, previous history of coronavirus disease-19 (COVID-19), or contact with any COVID-19 case was excluded. None of the patients showed signs of COVID-19 during sample collection. Pharyngeal and conjunctival swab samples were collected before the ophthalmic examination. Nucleic acid isolation from the samples was performed using an automated system. The presence of SARS-CoV-2 RNA in the samples was screened using a real-time polymerase chain reaction kit, and the positive samples were re-evaluated for the variant virus. RESULTS: Among the 127 patients with a median age of 40 weeks (range: 34–86) of postmenstrual age, positivity for SARS-CoV-2 RNA in the pharyngeal and conjunctival samples was 5/127 (3.93%) and 3/127 (2.36%), respectively. Isolated conjunctival positivity was not observed in any of the patients, and all three patients were positive for both conjunctiva and pharynx. CONCLUSION: Asymptomatic infants may be a reservoir for SARS-CoV-2, and conjunctival infection in infants may be a source of virus transmission. Since ROP screening cannot be postponed during the pandemic, caution should be exercised to prevent the spread of the disease
