Abstract

This study was conducted to evaluate visual field changes in TB patients on anti-tubercular therapy and to assess reversibility of these changes after discontinuation of therapy.

This study was conducted as a prospective study on all newly detected TB patients. Ocular examination was done at time of presentation, before initiating ATT. All patients were followed up periodically till cessation of treatment and three months thereafter.

A total of 40 cases of newly diagnosed TB were registered .There was significant deterioration in VA after 3 months of initiation of therapy. Once ATT was stopped, improvement in VA was statistically significant 3 months after the cessation of ATT as compared to VA 3 months after initiation of ATT .But residual visual impairment even after stoppage of ATT was observed. Color vison and visual field defects were observed in higher proportions of eyes following initiation of ethambutol which improved significantly after 3 months of cessation of ATT .
