We also chose not to perform taped and untaped measurements as published data does not support the idea that improved fields with taping or manual elevation of the eyelid is predictive of improved function after surgery.18 Many experts also feel that manually elevating the upper eyelid will underestimate the actual visual field improvement after ptosis surgery and simply adds to the time and expense of the pre-operative assessment.6. Thirty six were male and 61 were female. 1. The Humphrey Field Analyzer central 30-2 threshold test (HFA 30-2) and central 24-2 threshold test (HFA 24-2) are tests that can meet these criteria.
