Optometrists show varied glaucoma screening methods, with many unaware of subtle signs or omitting key tests like intra-ocular pressure measurement and visual field analysis. Patient awareness of glaucoma screening remains low despite regular optician visits.

Area of Science:

  • Ophthalmology
  • Optometry
  • Public Health

Background:

  • Glaucoma is a leading cause of irreversible blindness.
  • Early detection through screening is crucial for preventing vision loss.
  • Optometrists play a key role in community-based glaucoma detection.

Purpose of the Study:

  • To assess current glaucoma screening practices among optometrists in Nottingham.
  • To identify variations in diagnostic methods and referral criteria.
  • To evaluate patient awareness and recall of glaucoma screening.

Main Methods:

  • A survey was conducted among practicing optometrists in Nottingham.
  • Data collected included screening techniques, diagnostic criteria, and referral patterns.
  • Patient recall of screening was assessed in a general practice population aged 50+.

Main Results:

  • Significant variation observed in optometrists' screening methods and referral criteria.
  • 50% of optometrists missed subtle optic disc signs of glaucoma.
  • 8% never measured intra-ocular pressure, and 19% never performed visual field analysis.
  • Only 15% of patients aged 50+ recalled being screened for glaucoma, despite high optician visit rates.

Conclusions:

  • Optometrist glaucoma screening practices are inconsistent, potentially impacting early detection rates.
  • There is a need for standardized training and protocols for glaucoma screening in optometry.
  • Improving patient education and recall of glaucoma screening is essential for public eye health.
