EFFECT OF SQUINT SURGERY ON PUPILLARY DIAMETER

Aim-To investigate the effect that squint surgery has on pupillary dia meter. Methods-The effect of squint surgery on pupil size was investig ated in 19 patients. Results-A significant mydriasis in the operated e ye was observed when compared with the unoperated eye. This was indepe ndent of the number or type of extraocular muscles operated upon. Conc lusion-It is hypothesised that this change in pupillary diameter resul ts from the release of neurotransmitters from tissues damaged during s urgery.
