Experimental eye research·2025

Most glaucoma diagnoses occur during routine eye exams, often without symptoms. Elevated intraocular pressure (IOP) is the primary factor leading to glaucoma diagnosis, more so than visual field damage.

Area of Science:

  • Ophthalmology
  • Public Health

Background:

  • Glaucoma is a leading cause of irreversible blindness worldwide.
  • Understanding the diagnostic pathway is crucial for early detection and intervention.

Purpose of the Study:

  • To investigate the specific events and patient experiences leading to glaucoma diagnosis.
  • To identify the primary factors influencing the timing and detection of glaucoma.

Main Methods:

  • A prospective study involving a questionnaire administered to patients in a university glaucoma service.
  • Patients were asked about the circumstances surrounding their glaucoma diagnosis visit.

Main Results:

  • Over half of glaucoma patients were diagnosed during routine examinations, frequently without ocular symptoms.

  • Elevated intraocular pressure (IOP) was the most commonly recalled reason for diagnosis (61% of open-angle glaucoma patients).
  • Only 18% of open-angle glaucoma patients recalled diagnosis based solely on disc or visual field damage.

    • Conclusions:

    • Glaucoma detection is strongly linked to intraocular pressure (IOP) measurement.
    • The majority of glaucoma cases are identified during routine eye care visits, often in asymptomatic individuals.
    • Patient-reported data can enhance understanding of clinical practice patterns in glaucoma diagnosis.
