purpose: to evaluate the correlation between retinal nerve fiber layer (nfl) thickness and visual field parameters in patients with optic atrophy. methods: this study was performed on 35 eyes of 28 patients with optic atrophy. nfl thickness was measured by optic coherence tomography (oct) and visual field analysis was performed by humphrey perimetry. the correlation between nfl thickness and vi...

PURPOSE We evaluated threshold saccadic vector optokinetic perimetry (SVOP) and compared results to standard automated perimetry (SAP). METHODS A cross-sectional study was done including 162 subjects (103 with glaucoma and 59 healthy subjects) recruited at a university hospital. All subjects underwent SAP and threshold SVOP. SVOP uses an eye tracker to monitor eye movement responses to stimul...

OBJECTIVE To compare examination time and visual field loss for ptosis fields obtained with manual kinetic (Goldmann) perimetry and automated static (Humphrey) perimetry. METHODS Both eyes of 12 patients with bilateral aponeurogenic ptosis were prospectively examined using Goldmann and Humphrey (ptosis protocol) perimetry with the eyelids ptotic and taped into a normal position. RESULTS Bil...

Hydroxychloroquine retinopathy is a well-known toxic manifestation of a commonly used systemic medication. The aim of this study was to evaluate the role of automated perimetry in detecting early retinal involvement related to hydroxychloroquine therapy. The study group was made up of 25 patients (21 females and four males, average age 34.5 years) affected by rheumatological diseases treated wi...

We determined the disappearance eccentricities of dark and bright stimuli of equal size in the inferonasal central visual field using the oculokinetic perimetry technique at different levels of surrounding illumination. The results suggest that a dark stimulus on a bright background has a smaller 'isoptre' than an equally bright stimulus on a dark background, and that variation of ambient illum...

Macular ischaemia has a central role in the pathophysiology and prognosis of retinal macular disease. We attempted to quantitate two of its major components as follows: vascular nonperfusion, by measuring the foveal avascular zone (FAZ), using fluorescein angiography; and functional damage, using automated perimetry of the central 30 degrees. Sickle cell disease was chosen for study because it ...

Early diagnosis of glaucoma is critical to prevent permanent structural damage and irreversible vision loss. Detection of glaucoma typically relies on examination of structural damage to the optic nerve combined with measurements of visual function. To aid the clinician in evaluation of visual function and structure, computer-based devices such as confocal scanning laser ophthalmoscopy, scannin...

The visual fields of 13 children aged 7 to 16 (mean 10.7 years) were assessed by oculokinetic perimetry (OKP), a technique where the field of vision is tested at reading distance using a simple chart, and the results compared with conventional Goldmann perimetry. Cooperation with testing was greater for OKP than Goldmann perimetry and in some cases OKP was better correlated with clinical findin...

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...

Visual field (VF) testing is an important diagnostic tool for Glaucoma. The current gold standard for VF testing is automated perimetry. This article is an attempt to familiarize the reader with components of an achromatic (white on white) automated perimetry printout. It addresses use of Humphrey perimeter to interpret the results. For the purpose of this review, a PubMed search was made using...
