PURPOSE To present and evaluate a new method of estimating rates of retinal ganglion cell (RGC) loss in glaucoma by combining structural and functional measurements. DESIGN Observational cohort study. METHODS The study included 213 eyes of 213 glaucoma patients followed up for an average of 4.5 ± 0.8 years with standard automated perimetry visual fields and optical coherence tomography. A c...

Background: Motion detection perimetry and frequency doubling perimetry are methods that have been developed with the goal of detecting glaucomatous field defects earlier than conventional white-on-white perimetry. It is well recognized that the development of cataract and pupillary constriction can significantly influence perimetric thresholds when screening for, or following the progression o...

PURPOSE To investigate the effect of intraocular straylight (IOS) on threshold measurements made by four types of perimetry: standard automated perimetry (SAP), frequency-doubling technology (FDT) perimetry, flicker-defined form (FDF) perimetry, and the Moorfields Motion Displacement Test (MDT). METHODS Six healthy young (21-29 years) psychophysically experienced observers were tested five ti...

Objective: To evaluate structural and visual field (VF) changes after ≥1 year of a single acute primary angle closure (APAC) attack using spectral-domain optical coherence tomography (SD-OCT) standard automated perimetry (SAP). Methods: Patients with unilateral APAC crisis at least 1 ago were included consecutively from 2013 to 2016. Contralateral eye was used as control. All patients underwent...

PURPOSE To investigate the effects of divided attention on conventional automated perimetry (CAP) and luminance size threshold perimetry (LSTP). METHODS Ten healthy subjects, ages 27 to 65, with two perimetry types (CAP and LSTP) were tested in random order. At a later session, these tests were given with a mental workload to simulate the effect of anxiety or distraction on subjects performin...
