This study found multifocal VEP can detect early functional damage in 20% of glaucoma suspects with normal standard visual fields, suggesting its utility for early detection.

PERG amplitude was studied in glaucoma patients. Key finding: PERG loss can precede visual field defects, but some damaged eyes still show normal PERGs, limiting its diagnostic utility.

This study compared mfVEP and automated perimetry in early glaucoma, finding both tests detect similar damage, but each can miss abnormalities found by the other, suggesting their complementary use.

This study found multifocal VEP (mfVEP) has good repeat reliability (around 1.6dB) in healthy and glaucomatous eyes, even across days, suggesting it's a stable measure for clinical use.

Multifocal VEPs in glaucoma patients with unilateral defects revealed damage in seemingly unaffected visual fields, suggesting this test can detect subtle, early glaucoma progression missed by standard perimetry.
