Abstract

Aim: To assess the correlation between ethambutol dosage (per kg body weight) and duration and prevalence of ocular manifestation

Materials and Methods: Best Corrected visual acuity was determined by Snellen’s chart and color vision was assessed using an Ishihara chart. Slit lamp examination was done, followed by Perimetry to analyze visual fields. Dilated fundus photography was done for future comparison and record.

Results: All affected patients were on ethambutol dose of more than 15 mg per kg body weight at least for 2 months. On follow up of a patient after 1 month of stoppage of drug, both optic disc edema and visual field pattern improved.

Conclusion: Study underlines the importance of ocular examination at regular intervals before and during ethambutol treatment.
