  • Title: Effect of squint surgery on pupillary diameter.
    Author: James CB, Elston JS.
    Journal: Br J Ophthalmol; 1995 Nov; 79(11):991-2. PubMed ID: 8534669.
    Abstract:
    AIM: 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. CONCLUSION: It is hypothesised that this change in pupillary diameter results from the release of neurotransmitters from tissues damaged during surgery.
