Decrease of blue cone sensitivity in acute idiopathic blind spot enlargement syndrome.

Purpose: To determine the sensitivity of the blue cone system by static perimetry in patients with unilateral acute idiopathic blind spot enlargement (AIBSE) syndrome.

Design: Observational case series.

Methods: Four patients with AIBSE syndrome, aged 16 to 30 years, were studied.

Changes in the s-wave of multifocal electroretinograms in eyes with primary open-angle glaucoma.

Purpose: To determine whether the s-wave is present in the multifocal electroretinogram (mfERG) and whether it is altered in eyes with primary open-angle glaucoma (POAG).

Methods: A Visual Evoked Response Imaging System was used to record mfERGs from 15 eyes of 15 normal adults, as control eyes, and from 15 eyes of 15 patients with POAG. The stimulus consisted of 37 hexagonal stimulating elements with luminances of 200 cd/m(2) (white), 66.
