Sudden vision changes require prompt evaluation in the emergency department. This review outlines an organized approach to diagnosing urgent eye conditions like central retinal artery occlusion and acute angle-closure glaucoma.

Area of Science:

  • Ophthalmology
  • Emergency Medicine
  • Neuro-Ophthalmology

Background:

  • Vision changes are frequent emergency department complaints.
  • Causes range from minor trauma to sight-threatening emergencies.
  • A systematic approach is crucial for accurate diagnosis and timely treatment.

Purpose of the Study:

  • To present a structured approach for evaluating patients with visual loss.
  • To discuss the differential diagnosis of acute visual changes.
  • To highlight key evaluations for specific emergent ophthalmic conditions.

Main Methods:

  • Review of literature on emergency ophthalmology.
  • Systematic approach to history taking and physical examination for visual complaints.
  • Focus on specific vision-threatening conditions.

Main Results:

  • An organized diagnostic pathway aids in identifying serious causes of vision loss.
  • Differential diagnosis includes conditions affecting the retina, optic nerve, and anterior segment.
  • Specific conditions discussed include central retinal artery occlusion, central retinal vein occlusion, retinal detachment, acute angle-closure glaucoma, giant cell arteritis, and retrobulbar hemorrhage.

Conclusions:

  • A systematic evaluation is essential for managing patients with acute visual changes.
  • Prompt diagnosis and treatment are critical for preserving vision in emergent ophthalmic conditions.
  • Understanding the differential diagnosis guides appropriate emergency department management.
