In reply  The authors thank Dr Clearkin for his letter and agree that an improved ideal definition for "success of trabeculectomy" is required. Ideal success implies the preservation of all visual parameters including visual field and acuity. However, accurate assessment of the total visual status of a particular patient is difficult, time consuming, and expensive. An individual's visual performance varies from day to day, particularly in the assessment of visual field. Computerized automated perimetry has done much to improve this, but a simple and accurate, economically viable method of both high specificity and sensitivity for early detection of significant change in an individual's visual field has yet to be developed. In view of these problems, control of IOP has been used as the main criterion for success. Measurement of IOP is easy, accurate, reproducible, and objective and provides data that are easily analyzed statistically. Thus, the term success is synonymous
