Purpose Of Review: Studies have reported ocular involvement in the coronavirus disease 2019 (COVID-19), with SARS-CoV-2 having been detected in ocular swab samples. This has implicated the eye as a portal of transmission. The aim of this systemic review is to summarise and discuss the current literature regarding ocular involvement of SARS-CoV-2 in COVID-19.
Recent Findings: In this systematic review, the prevalence of ocular symptoms and signs was low (from 0 to 31.58%) and conjunctivitis was a relatively rare occurrence. The rate of detection of SARS-CoV-2 in the ocular swab samples was low as well and this ranged from 0 to 11.11%. The development of ocular symptoms and signs was not always accompanied by the detection of SARS-CoV-2 in the ocular swab samples. The opposite was described as well. This may reflect issues related to the characteristics of SARS-CoV-2 and of the study design. Nonetheless, the nature of research in a pandemic is that conclusions can change as more information is obtained.
Summary: Whilst the eye is unlikely to be a main transmission route, we need to consider the possibilities of conjunctivitis as a presenting complaint and of the eye playing a role in the transmission of SARS-CoV-2. Furthermore, we need to take the appropriate precautions in our practice. Further studies are needed to evaluate the viral tropism of SARS-CoV-2 and its role in the eyes.

Background: Graves' ophthalmopathy (GO) ocular abnormalities can persist even after treatment, negatively impacting patients' psychological and social health. The Indonesian Graves' Ophthalmopathy Quality of Life (GO-QoL) Questionnaire has not been validated, hence it cannot measure patient quality of life, which is crucial to GO treatment. We aimed to provide a reliable Indonesian GO-QoL Questionnaire and identify an association between patient quality of life and clinical activity and the severity of GO.

Background: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a multifactorial, chronic syndrome involving urinary frequency, urgency, and bladder discomfort. These IC/BPS symptoms can significantly impact individuals' quality of life, affecting their mental, physical, sexual, and financial well-being. Individuals sometimes rely on peer-to-peer support to understand the disease and find methods of alleviating symptoms.

Purpose To determine the corneal topographic characteristics of children with blepharokeratoconjunctivitis (BKC), a chronic inflammatory ocular surface disease involving the lid margin, conjunctiva, and cornea. Methods The corneal topography of 21 children diagnosed with BKC between March 2008 and June 2019 at a single institution were reviewed retrospectively. Pachymetry and asymmetry indices were also analyzed.

Because of its benign nature and rarity, circumscribed choroidal hemangioma (CCH) often receives limited attention, leading to a high rate of misdiagnosis and a lack of standardized treatment protocols. We provide a thorough clarification of the demographics, clinical features, diagnosis, management, and prognosis of CCH. We conducted a systematic search of the PubMed, EMBASE, and Ovid databases up to December, 2023, to identify relevant studies.

Objective: Whereas a few studies have evaluated vestibular involvement in Fabry disease (FD), the relationship between vestibular/oculomotor abnormalities and disease-specific biomarkers remain unclear. Therefore, we seek to evaluate these quantitatively and analyze their relationship with disease phenotype and biomarkers in FD.
Methods: This cohort study enrolled 37 Chinese FD patients registered in our center.
