Angioid streaks are linear breaks in Bruch's membrane, often linked to systemic diseases. Early diagnosis and management are crucial to prevent vision-threatening complications like choroidal neovascularization.

Area of Science:

  • Ophthalmology
  • Medical Genetics

Background:

  • Angioid streaks are characterized by linear dehiscences in Bruch's membrane.
  • These present with secondary changes in the retinal pigment epithelium and choriocapillaris.
  • They exhibit variable progression, appearance, and retinal involvement.

Purpose of the Study:

  • To describe the epidemiology, pathophysiology, diagnosis, and management of angioid streaks.
  • To review associated systemic diseases.
  • To emphasize the importance of differential diagnosis and referral for underlying conditions.

Main Methods:

  • Literature review on angioid streaks.
  • Analysis of associated systemic conditions.
  • Discussion of clinical presentation and management.

Main Results:

  • Optometrists must be able to diagnose angioid streaks.
  • Referral for evaluation of associated systemic diseases is essential.
  • Understanding the subtle ocular signs is key.

Conclusions:

  • Angioid streaks are rare, linked to conditions like pseudoxanthoma elasticum, Paget's disease, and sickle hemoglobinopathies.
  • Ocular complications include subretinal choroidal neovascularization.
  • Awareness of systemic associations and management protocols is critical for clinicians.
