A new method for eyelid elevation in glaucoma patients with ptosis during automated perimetry testing.

Purpose: Ptosis is a well-recognized confounding factor when interpreting superior visual field defects. As the current technique for eyelid elevation during automated perimetry is cumbersome and inconsistent, we developed a new technique. To evaluate its efficacy and feasibility, we studied a group of glaucoma patients with ptosis and superior visual field defects that had been attributed to nerve fiber layer defects.

Frequency doubling technology threshold testing in the pediatric age group.

Purpose: To evaluate the feasibility of performing visual field with the Frequency Doubling Technology (FDT) in children aged 5 to 10 years.

Patients And Methods: Forty healthy children and fifteen healthy adults, all with no previous experience with visual field testing, underwent visual field testing with the C20 threshold test of the Carl Zeiss Meditec FDT analyzer in both eyes. The subjects were divided into three groups.
