Abstract

Objective: The purpose of this study is to assess the refractive error and visual dysfunctions of students attending the basic educational system (12-15 years old) of the state of Sinaloa, Mexico. Methods: A total of 901 (451 female and 450 male) students in Sinaloa's basic school system participated in the study from 2020 to 2021. Optometrists and student clinicians from the Optometry Program of the Autonomous University of Sinaloa conducted the testing. Tests included visual acuities and static retinoscopy. We used a cycloplegic agent for those with far visual acuity equal to or worse than 20/40, accordingly to the Refractive Error Study in Children protocol. Results: The results showed a high prevalence of uncorrected refractive errors. Myopia, defined as a spherical equivalent r ≤ -0.50 D, had a prevalence of 24.7% (95% CI: 21.5— 27.5).Hyperopia, defined as a spherical equivalent refractive error ≥ +2.00 D, had a prevalence of 2.04% (95% CI: 1.14 - 3.19).Astigmatism, defined as a refractive error with a cylinder ≥ -0.75 D had a prevalence of 19.8% (95% CI: 16.9—22.5). We did not find a significant effect of sex on visual acuity. Conclusion: Our results are consistent with a high prevalence of myopia reported in children worldwide and in Mexico's northern regions. The results suggest that children attending the basic educational system should have an optometric eye examination.

Meningoencephalitis associated with Third Cranial Nerve Palsy by SARS-CoV-2: Report of a Case

Abstract

Objective: To inform the ophthalmologist of the importance of ruling out the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in the current context of this pandemic, in a patient with neuro-ophthalmological symptoms without respiratory compromise. Observation: 41-year-old male presented to the ophthalmologist for palsy of the III and IV cranial nerves and anterior optic neuritis of the left eye. A Polymerase Chain Reaction (PCR) test was requested for SARS-CoV-2 being positive. Conclusions: Neuro-ophthalmological involvement in a patient with SARS-CoV-2 infection is an alarm data for a severe course of the disease, diagnosing it in the absence of respiratory symptoms is a diagnostic challenge, we must carry out a careful questioning about a recent history of respiratory symptoms or fever, and perform RT-PCR for SARS-CoV-2, avoid delays in its diagnosis, will improve the prognosis of life of the patient.
