—We appreciate Dr Lieberman's comments regarding the treatment of exposed glaucoma setons. This difficult problem developed more frequently prior to the use of fullthickness scleral patch grafts to cover glaucoma implants, but still occurs on occasion. The use of scleral patch grafts during the surgical revision of exposed glaucoma implants appears to improve the likelihood of success, compared with conjunctivoplasty alone (with or without repositioning of the tube). We look forward to reports of the use of autologous fascial grafts as an alternative technique for this purpose. If this alternative proves superior, it may become preferable to the use of scleral patch grafts at the time of initial surgery, particularly in this era of concern about blood-borne diseases.
