Travatan is unlikely to be affecting pupil dilatation. Pupil dilatation and glare could be due to raised eye pressure.The other possibility could be the mydriatic that is used to dilate your eyes could be longer acting like cyclopentolate or atropine. You can discuss with your ophthalmologist. Thanks and best wishes.
Travatan is not known to affect dilatation. Your eye pressure keeps fluactuating. No doubt travatan would help to lower the pressure but it is possible that dilatation may have increased the eye pressure which is responsible for these symptoms and when the pressure is controlled again these symtoms will go. Dilatation can increase the eye pressure by obstructing the flow of fluid in the anterior part of the eye. Thanks.
