Effect of squint surgery on pupillary diameter.
OBJECTIVE
To investigate the effect that squint surgery has on pupillary diameter.


METHODS
The effect of squint surgery on pupil size was investigated in 19 patients.


RESULTS
A significant mydriasis in the operated eye was observed when compared with the unoperated eye. This was independent of the number or type of extraocular muscles operated upon.


CONCLUSIONS
It is hypothesised that this change in pupillary diameter results from the release of neurotransmitters from tissues damaged during surgery.
