The Division of Ophthalmology offers special testing not routinely available for children elsewhere, including vision testing for preverbal children, orthoptic evaluation and treatment, adult and pediatric visual field testing, electroretinography (awake or with sedation), visual evoked responses and ultrasonography.
Clinical services available within the Division include orthoptics, aphakic contact lenses, electroretinography, visual evoked potential, ultrasonography, non-invasive functional visual testing, and complete ocular photography.
A series of examinations were performed on the patients, including the fundus fluorescein angiography, optical coherence tomography, GDxVCC Nerve Fiber Analyzer, full-field electroretinography, multifocal electroretinography and visual field examinations, to provide a better understanding of chloroquine retinopathy.
Tests of her eyes using electroretinography revealed a severe dysfunction in the rod and cone cells responsible for vision, and other irregularities in each eye.
With help of electroretinography (ERG), a specialized measure of retinal function, the researchers observed that the ability of light to activate rods was significantly reduced in currently healthy individuals who descended from multigenerational families that had members diagnosed with either schizophrenia or bipolar disorder.
However, a low level of retinal activity, measured by electroretinography, indicates very little visual function.
The men had comprehensive vision exams at the beginning and at the end of the study, including electroretinography (ERG, a test used to detect diseases of the retina).
The men underwent comprehensive ophthalmologic examinations including electroretinography (a test to measure the electrical response of the light-sensitive rods and cones in the eye, used to detect diseases of the retina) before, during and after treatment.
Among the 194 men (79.5 percent) who completed the study, no significant differences were found between treatment and placebo groups on electroretinography, visual function tests, measurements of intraocular pressure (pressure within the eyeball) or assessments of the anatomy of the eye.
