A database for normal macular thickness and sensitivity was generated with a combined microperimetry SD-OCT system as the basis for comparison of outcome parameters in patients with macular abnormality. Mean retinal sensitivity decreased significantly only in the age group of participants ≥ 70 years and in peripheral portions of the macula in individuals aged ≥60 years, with increasing distance from the fovea, while other parameters, their correlations and covariates, were not affected within the normative data set. No relationship was detected between retinal thickness and retinal sensitivity in the healthy macula.

Among patients undergoing trabeculectomy by supervised residents or glaucoma fellows in a large Veterans Affairs Medical Center, IOP reduction was significant and similar to published studies. Trabeculectomy remains a successful intervention to lower IOP, with satisfactory success rates in the hands of trainee surgeons.
