PURPOSE: To evaluate pupil dilation from intracameral injection of nonpreserved 1% lidocaine. DESIGN: Observational case series of 25 consecutive phakic trabeculectomies. METHOD: Patients were evaluated in the operating room setting and given one drop of topical tetracaine preoperatively. Nonpreserved 1% lidocaine (0.1 ml) was injected intracameraly into the anterior chamber through a paracentesis site at the corneal limbus. Pupil diameter was measured after instillation of topical tetracaine, before injection of intracameral lidocaine. Postinjection measurements were made at one, three, and five minutes. RESULTS: The mean male pupil diameter was significantly greater than female dilation at every time point. The mean blue iris diameter was greater than brown at 1 and 3 minutes, but there was no difference at five minutes or more. There was no racial difference in the pupil dilation response to intracameral lidocaine. CONCLUSIONS: Nonpreserved intracameral 1% lidocaine produces immediate pupil dilation in previously undilated phakic patients during trabeculectomy surgery.
