THE SCHOCKET TUBE - RETROSPECTIVE STUDY O F 36 CASES

Thirty-six eyes with refractory glaucoma were operated using a Schocke t technique (anterior chamber shunt to an encircling band). The follow -up was more than one year in all cases with a two-year maximum follow up. The intraocular pressure was less-than-or-equal-to 25 mmHg in 87. 5 % to 95 % of cases, and < 21 mmHg in 75.8 % to 81.5 9 % of cases. Th e results were analysed for each etiology and compared with those of o thers series and those of other surgical techniques used in the treatm ent of this type of glaucoma. (Molteno drainage tube, cyclodiathermy, ultrasonic treatment and yag laser transcleral contact cyclophotocoagu lation).
