Pilocarpine spray: an alternative delivery method.
To determine if pilocarpine 4% produces miosis when delivered via a spray, eleven eyes of ten patients undergoing a laser peripheral iridotomy for occludable angles were pretreated with one application of pilocarpine spray to closed eyelids. Standardized pupil photographs for pupil diameter measurements were taken before and thirty minutes after the spray. Contralateral eyes served as controls (9 eyes) All treated eyes achieved miosis. The mean pupil diameter in the treated group was 4.1+/-0.9 mm before the spray and 1.5+/-0.3 mm after the spray (p < 0.0001). The average change in pupil diameter in the treated group was 2.6+/-0.9 mm compared to 0.0+/-0.2 mm in the control eyes (p < 0.0001). Pilocarpine spray is an effective delivery modality for intraocular miosis.
