Answer

Answer

The initial postoperative IOP measurements could be influenced by residual effects of the patient's previous topical IOP-lowering medications. If possible, oral medication (ie, acetazolamide) should be substituted for the topical medications several days to 2 weeks before the trabeculectomy. The rapid washout period of acetazolamide allows for a more accurate idea of the effect of surgery on the postoperative IOP.
