Utility of the Modified Isolated-check Visual Evoked Potential Technique in Functional Glaucoma Assessment.

Unlabelled: PRE[COMBINING ACUTE ACCENT]CIS:: Cortical response to low-contrast stimuli, as measured by isolated-check visual evoked potential (icVEP) technology, has the potential to provide functional assessment that may complement standard achromatic perimetry in assessing glaucomatous change.

Purpose: To evaluate the utility of modified icVEP testing in detecting functional glaucomatous damage.

Materials And Methods: Subjects who met predetermined criteria of controls, glaucoma suspects, preperimetric glaucoma, or glaucoma were enrolled in this prospective cross-sectional study from a single tertiary care center.

Within-subject assessment of foveal avascular zone enlargement in different stages of diabetic retinopathy using OCT reflectance and OCT angiography.

Enlargement of the foveal avascular zone (FAZ) due to progressive capillary nonperfusion is associated with visual deterioration in patients with diabetic retinopathy. The FAZ area has long been considered an important clinical marker of advancing retinopathy. However, a large body of literature shows that the FAZ area varies considerably in healthy eyes, resulting in substantial overlap between controls and diabetics, thus reducing its discriminatory value.
