Probing glaucoma visual damage by rarebit perimetry.
AIM To compare rarebit perimetry (RBP) with standard achromatic perimetry (SAP) in detecting early glaucomatous functional damage. METHODS 43 patients with ocular hypertension (OH), 39 with early primary open angle glaucoma (POAG), and 41 controls were considered. Visual fields were assessed using the Humphrey field analyser (HFA) 30-2 and RBP tests. Differences among the groups were evaluate...
متن کاملA new visual field test in empty sella syndrome: rarebit perimetry.
PURPOSE Several visual field defects can be seen in empty sella syndrome (ESS). In this study, the authors aimed to evaluate the visual field defects in patients with ESS by rarebit perimetry and to compare the results with Humphrey perimetry. METHODS Left eyes of 13 patients with ESS and left eyes of 15 age-matched normal subjects were included in the study. Visual field testing was performe...
متن کاملIdentifying "preperimetric" glaucoma in standard automated perimetry visual fields.
PURPOSE To compare the visual fields (VFs) of preperimetric open angle glaucoma (OAG) patients (preperimetric glaucoma VFs, PPGVFs) with the VFs of healthy eyes, and to discriminate these two groups by using the Random Forests machine-learning method. METHODS All VFs before a first diagnosis of manifest glaucoma (Anderson-Patella's criteria) were classified as PPGVFs. Series of VFs were obtai...
متن کاملTesting Spatial Detection and Light Sensitivity in Homonymous Hemianopia by Rarebit and Conventional Automated Perimetry
Purpose of the study was to compare Rarebit Perimetry (RP) with Standard Automatic Perimetry (SAP) in patients with ischemic retrochiasmal lesions. Seventeen patients with homonymous hemianopia underwent SAP and RP. Correlation between the two techniques was evaluated, congruent defects were quantified in the spared hemifield and residual vision areas were investigated in the blind hemifield. A...
متن کاملLearning Effect and Test-Retest Variability in Healthy Subjects and Patients with Primary Open Angle Glaucoma Using Rarebit Perimetry
Aim: To study learning effect (LE) and test retest variability (TRV) in healthy subjects and patients with primary open angle glaucoma (POAG) using Rarebit perimetry (RBP). To determine normative ranges of RBP. Methods: 61 eyes of 35 subjects underwent visual field testing with standard automated perimetry (SAP) and RBP. TRV and LE were assessed in repeated examinations conducted in 3 different...
