Triamcinolone particles can form a pseudo-cataract on the lens after intravitreal injection for macular edema. These unusual deposits persisted for over six months in this case report.

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Pharmacology

Background:

  • Macular edema secondary to non-ischemic central retinal vein occlusion is a common cause of vision loss.
  • Intravitreal injections of corticosteroids, such as triamcinolone acetonide, are a standard treatment for this condition.
  • While generally safe, corticosteroid injections can have ocular side effects.

Observation:

  • A case report details a patient who developed a pseudo-cataract after a 2-mg intravitreal triamcinolone injection.
  • The pseudo-cataract was characterized by the adherence of triamcinolone particles to the posterior lens surface.
  • These deposits were noted to persist unusually long, beyond the typical resolution period.

Findings:

  • The adherence of triamcinolone particles to the lens can mimic cataract formation.

Related Experiment Videos

  • The persistence of these deposits for over six months is an atypical clinical observation.
  • This highlights a potential, albeit rare, complication of intravitreal triamcinolone acetonide therapy.

    • Implications:

    • Clinicians should be aware of the possibility of pseudo-cataract formation from triamcinolone particles.
    • Extended persistence of these deposits may warrant further investigation or management considerations.
    • This case contributes to the understanding of the long-term ocular effects of intravitreal corticosteroid injections.
