    Transient vision loss in an elderly man was linked to carotid artery disease, despite normal eye pressure. This case highlights the connection between vascular issues and low-tension glaucoma.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Medicine

    Background:

    • Transient visual disturbances can be caused by various factors, including cerebrovascular events.
    • Low-tension glaucoma (LTG) is characterized by optic nerve damage and visual field loss with normal intraocular pressure.
    • Carotid artery disease is a significant risk factor for ischemic stroke and transient ischemic attacks.

    Observation:

    • A 72-year-old male patient experienced recurrent episodes of gradually descending vision loss affecting each eye sequentially.
    • Ophthalmic examination revealed significant optic disc cupping in both eyes.
    • Applanation tonometry indicated normal intraocular pressure, ruling out typical glaucoma suspects.

    Findings:

    • The patient had significant carotid occlusions, indicating severe cerebrovascular disease.

    Related Experiment Videos

  • The transient visual disturbances were hypothesized to be related to transient hypoperfusion secondary to carotid occlusive disease.
  • A potential link between carotid artery disease and the pathogenesis of low-tension glaucoma was suggested.

    • Implications:

    • This case underscores the importance of considering vascular etiologies, such as carotid occlusive disease, in patients presenting with unexplained visual disturbances, even with normal intraocular pressure.
    • It suggests a potential association between carotid disease and low-tension glaucoma, warranting further investigation into shared pathophysiological mechanisms.
    • Management strategies for such patients should involve a multidisciplinary approach, addressing both ocular and vascular health to prevent further visual deterioration and systemic complications.
