Résumé
Introduction: wearing masks for a prolonged amount of time can decrease work efficiency by causing a host of physiological or psychological problems. The use of masks, in particular, for extended periods of time causes physical adverse effects such as difficulty breathing, mask-induced acne, rashes, headache and sometimes, impaired cognition. Objectives: To assess the impact of using N95 masks by a part of the population using spectacles. Materials and Methods:After taking informed consent, 270 spectacles and mask users were enrolled for this single centre, questionnaire based, cross-sectional observational study. Results: A large proportion (70.2%) of the respondents complained of fogging of spectacle lens on wearing N95 masks which impaired their vision to variable extent and also impaired the daily activity. Conclusion: This study identified the impact of N95 masks on quality of vision in spectacle users and various recommendations are presented for prevention and management of these adverse effects.
Résumé
Tuberculous optochiasmatic arachnoiditis (OCA) is a rare complication of tuberculous meningitis. We describe a 47-year-old female with tuberculous OCA confused with ethambutol-associated optic neuropathy. She was on anti-tuberculous treatment (i.e., isoniazid, rifampin, ethambutol, and pyrazinamide) for two months due to tuberculous meningitis. Visual impairment occurred during treatment, and ethambutol was changed to levofloxacin because of concern for ethambutol-associated optic neuropathy. Her visual impairment did not improve three months after anti-tuberculous treatment that excluded ethambutol, and she was referred to our hospital. Brain MRI showed enhancement of the optic chiasm and bilateral optic tract, and fundoscopy revealed bilateral optic nerve atrophy, suggesting tuberculous OCA. Her visual acuity was partially improved after anti-tuberculous treatment. Tuberculous OCA should be considered in addition to ethambutol-associated optic neuropathy for a patient with tuberculous meningitis who presents with visual impairment.
