Ability of Short wavelength automated perimetry to detect visual field changes in diabetic patients

SVU - International Journal of Medical Sciences, 2022
Background: Globally, diabetes-related eye illness is the primary cause of visual impairment due to cataracts or retinopathy. The two most used visual field testing modalities in clinical practice are standard automated white-on-white (W-W) perimetry ...

High‐Resolution Microperimetry for Detecting Glaucomatous Damage: A Prospective Evaluation of Performance

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To compare the performance of high‐resolution microperimetry testing against standard automated perimetry (SAP) for detecting glaucomatous damage seen on optical coherence tomography (OCT) scans. Methods 250 eyes from 200 individuals underwent high‐resolution microperimetry testing of a hemifield using a stimulus pattern optimised ...

Long-term variability in short-wavelength automated perimetry compared to standard perimetry in glaucoma patients and normal subjects

Oman Journal of Ophthalmology, 2009
Aims: To compare long-term variability (LTV) in short-wavelength automated perimetry (SWAP) with that of standard white-on-white (W-W) perimetry, in primary open angle glaucoma (POAG) patients and normal subjects and to determine its clinical ...

Assessment of glaucoma severity and deterioration by using Spaeth/Richman contrast sensitivity (SPARCS) and its correlation with retinal nerve fiber layer thickness and perimetry

Indian Journal of Ophthalmology
Purpose: To assess the severity of glaucoma and its worsening using Spaeth/Richman contrast sensitivity (SPARCS). To evaluate its correlation with retinal nerve fiber layer thickness (RNFL) and perimetry. Methods: In this prospective observational study,

Autonomy in children and adolescents with visual impairment: Validation of the Visual Impairment Developmental Autonomy scale

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To validate the Visual Impairment Developmental Autonomy (VIDA) scale, a questionnaire to assess the autonomy level of children with visual impairment. Method The primary outcome measures included internal consistency, convergent validity, cross‐informant concordance, and descriptive statistics of autonomy profiles across three age groups (

Hard braking events in bioptic drivers with central vision impairment

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose Some individuals with central vision impairment can obtain or maintain driving privileges using bioptic telescopes. Previous work has often demonstrated an increased collision risk for bioptic drivers, but some on‐road studies find similar safety to that of normally sighted drivers.
