Design: Cross-sectional study.
Method: A survey of 20 chest physicians, 20 opthalmologists and 200 patients suffering from obstructive airway disease was conducted in 2 hospitals and a welfare center of Karachi from August to September 1997. Results: The results indicate that opthalmologists showed more awareness than chest physicians regarding use of beta blocker eye drops by patients with obstructive airways disease (p=0.004). Patient awareness was low as well.
Conclusion: There is a need to update doctors and educate general public about the side effects of beta blocker eye drops in patients with obstructive airway disease
