ABSTRACT
BACKGROUND: The present study reports the functional and anatomical outcomes of eyes with acute retinal necrosis(ARN). METHODS: This is a retrospective case series conducted at a tertiary Eye Hospital from March 2015 to March 2020. Medical records of patients with clinical and laboratorial-Polymerase Chain Reaction (PCR)-diagnosis of ARN were reviewed. To identify factors related to the outcomes of visual acuity(VA) and retinal detachment (RD) over time, Cox proportional hazards regression modeling and survival analyses were used. RESULTS: Twenty-three eyes of 23 patients (16 male, 7 female) were reviewed. Based on the PCR results, 16 cases (69.6%) had Varicella zoster virus, 3 cases (13%) had Cytomegalovirus, 1 patient (4.3%) had Herpes simplex virus associated ARN, and 1 case (4.3%) had negative PCR. The incident rate for ≥ 2-line VA gain was 0.28/eye-year (EY) (95% CI 0.21 ± 0.26) while the rate of severe vision loss was 0.09/eye-year (95% CI 0.05 ± 0.08). The RD development was observed at a rate of 0.43/eye-year (0.42 ± 0.02), which occurred in 9 eyes with a mean time of 100 days after the initial presentation of ARN. Patients' age was the only factor associated with 2-line or more gain in VA over time with a hazard ratio of 0.921 (95% CI 0.854-0.993, P = 0.032). CONCLUSIONS: Generally, although being crucial, treatment is not highly effective in improvement of VA and decrease of RD development, as well as vision loss, in patients with ARN. However, treatment prevents fellow eye involvement efficiently. Younger age is associated with better response to treatment and more chance to achieve better VA.
ABSTRACT
Purpose: Herein, we report a case of bilateral neuroretinitis and panuveitis in a patient recovered from coronavirus disease 2019 (COVID-19).Case presentation: A 37-year-old male patient with a history of recovered COVID-19, which was confirmed with nasopharyngeal reverse transcriptase polymerase chain reaction (RT-PCR) for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), about one-month ago was referred with one-week history of bilateral severe vision loss. Visual acuity was counting fingers, and bilateral retinitis and panuveitis were revealed in ocular examination. The result of the vitreous sample using RT-PCR was positive for SARS-CoV-2 and negative for Herpesviridae viruses and mycobacterium tuberculosis. The patient was successfully treated with corticosteroid.Conclusion: We report a case of bilateral neuroretinitis and panuveitisin a recovered COVID-19 patient and positive RT-PCR of the vitreous sample. It is suggested to apply intraocular sampling and evaluation for COVID-19 in patients with the new-onset of uveitis and/or retinitis during the pandemic.
