Measure what the eyelid hides. When a drooping eyelid limits a patientโs vision, a dedicated superior field test shows how much of the upper visual field is affected.
PTS 2000 offers three test fields designed specifically for ptosis: Sup 36, Sup 44 and Sup 64. Each concentrates test points in the upper part of the field, with a different number of points, so you can choose the field that best fits the case. Running the test with the eyelid in its natural position and again with the eyelid taped lets you compare both results.
