PURPOSE To compare conventional structural and functional measures of glaucomatous damage with a new functional measure-contrast sensitivity perimetry (CSP-2). METHODS One eye each was tested for 51 patients with glaucoma and 62 age-similar control subjects using CSP-2, size III 24-2 conventional automated perimetry (CAP), 24-2 frequency-doubling perimetry (FDP), and retinal nerve fiber layer...
With the multifocal technique, visual evoked potentials (VEPs) can be recorded simultaneously from many regions of the visual field in a matter of minutes. Recently, the multifocal visual evoked potential technique (mfVEP) has generated considerable interest, especially among those seeking objective measures of glaucomatous damage. It is well accepted that significant ganglion cell damage can o...
PURPOSE To illustrate the potential role for Heidelberg edge perimetry (HEP) in the assessment of early functional loss in glaucoma. CASE REPORT A 46-year-old male presented with raised intraocular pressure but healthy optic discs and normal standard automated perimetry (SAP). He was diagnosed with ocular hypertension, but after 16 years, he developed glaucomatous changes to the right optic d...
OBJECTIVE To compare optical coherence tomography (OCT) measurements on the retinal nerve fiber layer (RNFL) of healthy controls and patients with longitudinally extensive transverse myelitis (LETM) without previous optic neuritis. METHOD Twenty-six eyes from 26 patients with LETM and 26 control eyes were subjected to automated perimetry and OCT for comparison of RNFL measurements. RESULTS ...
Purpose To compare the structure-function relationships between retinal nerve fiber layer thickness (RNFLT) and visual field defects measured either by standard automated perimetry (SAP) or by Pulsar perimetry (PP). Materials and Methods 263 eyes of 143 patients were prospectively included. Depending on the RNFLT, patients were assigned to the glaucoma group (group A: RNFL score 3-6) or the c...
Primary open-angle glaucoma (POAG) firstly mainly affects peripheral vision. Current behavioral studies support the idea that visual defects of patients with POAG extend into parts of the central visual field classified as normal by static automated perimetry analysis. This is particularly true for visual tasks involving processes of a higher level than mere detection. The purpose of this study...

Perimetric evaluation of saccadic latency, saccadic accuracy, and visual threshold for peripheral visual stimuli in young compared with older adults. Invest Ophthalmol Vis Sci. 2013;54:5778– 5787. DOI:10.1167/iovs.13-12032 PURPOSE. Using a novel automated perimetry technique, we tested the hypothesis that older adults will have increased lat...
It has been assumed that the retinal threshold sensitivity profile is a standard which decreases predictably with age. On this basis the significance of relative scotomata is decided on certain types of perimeter. The hill of vision was measured in 128 healthy eyes on the Dicon 2000 autoperimeter. We found a large variation between individuals, with no relationship to age. The relevance of the ...
