View Poster
Glaucoma Repeat Reading Services (GRRS) are an integral part of glaucoma referral filtering in primary care optometry, designed to reduce unnecessary referrals to Hospital Eye Services (HES) following routine sight tests. Endorsed by NICE and GIRFT, GRRS aims to minimise false positive referrals by enabling accredited practitioners to repeat key measurements in cases of raised intra-ocular pressure or suspicious visual field defects. While earlier evaluations were limited in scope and dated, this study presents a comprehensive review of GRRS outcomes across 26 Integrated Care Boards in England from 2021 to 2025, offering updated insights into the effectiveness and impact of these services on patient care and system efficiency.
