Purpose: To describe the demographics, clinical characteristics, and presentation of solar retinopathy in patients who presented to a multi-tier ophthalmology hospital network in India. Methods: This cross-sectional, hospital-based study included 3,082,727 new patients presenting to the hospital between August 2010 and December 2021. Patients with a clinical diagnosis of solar retinopathy in at least one eye were included in the study. All the data was collected using an electronic medical record system. Results: Three hundred and forty-nine eyes of 253 (0.01%) patients were diagnosed with solar retinopathy and included in the study, and 157 patients (62.06%) had a unilateral affliction. Solar retinopathy was noted to be significantly more common in males (73.12%) and adults (98.81%). The most common age group at presentation was during the sixth decade of life with 56 (22.13%) patients. They were more commonly from the rural geography (41.9%). Among the 349 eyes, 275 (78.8%) eyes had mild or no visual impairment (<20/70), which was followed by moderate visual impairment (>20/70–20/200) found in 45 (12.89%) eyes. The most commonly associated ocular comorbidity was cataract in 48 (13.75%) eyes, followed by epiretinal membrane in 38 (10.89%) eyes. The most common retinal damage seen was interdigitation zone (IZ) disruption (38.68%), followed by inner segment–outer segment (IS–OS) disruption (33.52%). Foveal atrophy was seen in 105 (30.09%) eyes. Conclusion: Solar retinopathy is predominantly unilateral and is more common in males. It usually presents during the sixth decade of life and rarely causes significant visual impairment. The most common retinal damage seen was disruption of the outer retinal layers.
Introduction: To describe the demographics and clinical profile of synchysis scintillans in patients presenting to a multitier ophthalmology hospital network in India. Methods: This cross-sectional hospital-based study included 3,082,727 new patients presenting between August 2010 and December 2021. Patients with a clinical diagnosis of synchysis scintillans in at least one eye were included as cases. The data were collected using an electronic medical record system. Results: Overall, 93 (0.003%) patients were diagnosed with synchysis scintillans. About half of the patients were male (50.54%) and had unilateral (81.72%) affliction. The most common age group at presentation was during the seventh decade of life with 38 (40.86%) patients. The overall prevalence was higher in patients from a higher socioeconomic status (0.003%) presenting from the metropolitan geography (0.005%) and in retired individuals (0.018%). A systemic history of diabetes mellitus was documented in 13 (13.98%) patients and hypertension was documented in 15 (16.13%) patients. The majority of the eyes had mild or no visual impairment (<20/70) in 74 (67.27%) eyes. The most commonly associated ocular comorbidity was cataract in 61 (55.45%) eyes followed by glaucoma in eight (7.27%) eyes. Among the surgical interventions performed for the ocular comorbidities, cataract surgery was performed in nine (8.18%) eyes, and vitreoretinal surgery and trabeculectomy were performed in two (1.82%) eyes each. Conclusion: Synchysis scintillans equally affect males and females presenting during the seventh decade of life and is predominantly unilateral. The majority of the eyes have mild or no visual impairment and over half of the eyes have an associated cataract.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
