Popis: * BACKGROUND AND OBJECTIVE: American Glaucoma Society members were surveyed to determine the pattern of use of viscoelastics for anterior chamber reformation at the slit-lamp in the post-operative clinical management of patients who have undergone trabeculectomy in order to give ophthalmologists an indication of how these materials are being used by their colleagues. * MATERIALS AND METHODS: We surveyed 196 members of the American Glaucoma Society regarding the following; (1) whether they inject viscoelastic post-operatively at the slit-lamp as an inoffice procedure, (2) the type of viscoelastic used most often, (3) the criteria for injection of viscoelastic, (4) the time to first follow-up, (5) the average number of injections, and (6) the occurrence of post-injection endophthalmitis. * RESULTS: One hundred twenty-five (64%) of the 196 mailed surveys were answered and returned. Ninety-four (75%) of the respondents reported injecting viscoelastics in the postoperative period at the slit-lamp as an in-office procedure. Healon (60%) (Pharmacia & Upjohn Co, Kalamazoo, MI), Viscoat (17%) (Alcon, Ft. Worth, TX), and Healon GV (7%) (Pharmacia & Upjohn Co, Kalamazoo, MI) were the three most often used viscoelastics. Hypotony, iris-cornea touch, and lens-cornea touch were given as criteria for injection 19%, 47%, and 88% of the time, respectively. Range of time to first follow-up was 1 hour to 7 days, with a mean time of 1 day. Range of average number of injections was 1 to 3 with a mean of 2 injections for patients requiring injection. Only one respondent reported an incidence of endophthalmitis. * CONCLUSIONS: The use of viscoelastic materials in the postoperative trabeculectomy patient in the office at the slit-lamp for anterior chamber reformation is a prevalent practice. Healon is the most commonly used viscoelastic postoperatively and lens-corneal touch is the most common criterion for injection. The average number of injections is 2, with a mean and mode follow-up time of 1 day. Endophthalmitis is a rare complication. [Ophthalmic Surg Lasers 1999;30:271-275.]
