The Effect of Perioperative Uveitis Control on the Success of Glaucoma Surgery in Uveitic Glaucoma.

Abstract

PurposeTo study the effects of perioperative uveitis control (PUC) on postoperative intraocular pressure (IOP) and uveitis activity in uveitic glaucoma (UG) patients who required glaucoma surgeries.Patients and MethodsA retrospective chart review of 109 patients (120 eyes) which had glaucoma surgery for UG. A total of 66 eyes which had PUC were compared to 54 eyes which did not have. Measurements of IOP and uveitis activity were recorded preoperatively and over 2 years postoperatively. Average number of antiglaucoma medications and frequency of surgical failure were obtained in both groups.ResultsOver 2 years postoperatively, average IOP was lower in eyes which had PUC. Significant differences in IOP were found at 3 months (P = 0.004), 6 months (P = 0.001), 1 year (P < 0.001), and 2 years (P < 0.001). Lower grades of anterior chamber (AC) inflammation were found in eyes which had PUC. Significant differences were found at 1 month (P < 0.001), 3 months (P < 0.001) and 6 months (P = 0.001). Mean number of antiglaucoma medications at last visit was 0.7 ± 1.1 for eyes which had PUC and 2.6 ± 1.5 for eyes which did not have PUC (P < 0.001). Among eyes which had PUC, only two eyes required second glaucoma surgeries, while 16 eyes with no PUC required further glaucoma surgeries after 27.7 ± 12.5 months (P < 0.001).ConclusionProper PUC in patients going for UG surgeries results in lower IOP levels and less AC inflammation over 2 years postoperatively. A comprehensive PUC regimen is needed for uveitic glaucoma patients going for surgeries.
