Purpose Coronavirus disease 2019 (COVID-19) is an ongoing global public health problem, and most of the COVID-19 research is focused mainly on the respiratory system because of life-threatening results. However, manifestations in other organs should not be ignored since they can also be a mode of transmission. We sought to describe the ocular manifestations of COVID-19 and investigate the association between ocular involvement and clinical presentation and laboratory outcomes. Methods This cross-sectional study was conducted between March 1, 2020, and April 30, 2020. Ninety-three sequentially hospitalized and clinically confirmed COVID-19 patients were included in the study. The systemic and ocular symptoms, clinical findings, and laboratory outcomes were recorded. Results Of the 93 COVID-19 patients, 54 (58.1%) were male, and 39 (41.9%) were female. Mean age of the patients was 39.4 ± 21.9 (min 7, max 88) years. Twenty patients (n 21.5%) had at least one ocular abnormality. Most common findings included hyperemia (n = 20), epiphora (n = 9), increased secretion (n = 6), chemosis (n = 3), follicular conjunctivitis (n = 2), and episcleritis (n = 2). The most common symptom was photophobia (n 15). Patients with ocular involvement were more likely to have higher neutrophil counts (p = 0.001), and increased CRP (p < 0.001), PCT (p = 0.001), and ESR levels (p < 0.001). Mean lymphocyte count was statistically lower in patients with ocular manifestations (p = 0.001). Mean age and number of patients with fever over 37.3°C in the ocular involvement group was found to be higher (p < 0.001, p = 0.006, respectively). Conclusion Older age, high fever, increased neutrophil/lymphocyte ratio, and high levels of acute phase reactants seemed to be risk factors for ocular involvement.
Although closure was reliable in both groups, the microcoaxial group had slightly fewer undesirable effects on the incision site. Low postoperative IOP seemed to be a significant factor in problematic healing.
Treatment-naive keratoconus patients have significantly higher corneal densitometry values in central cornea when compared to healthy control subjects. The clinical relevance should be further studied in detail.
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.
