Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Pharmacology

Background:

  • Diabetic macular edema (DME) is a leading cause of vision loss in diabetic patients.
  • Refractory DME often requires long-term treatment strategies.
  • Intravitreal steroid implants are used for DME, but intralenticular placement is uncommon.

Observation:

  • A case report details a sustained-release dexamethasone implant (Ozurdex) placed within the crystalline lens for 1 year.
  • The implant effectively resolved diabetic macular edema, confirmed by clinical examination and optical coherence tomography.
  • No rapid cataract formation was observed during the 12-month observation period.

Findings:

  • The intralenticular Ozurdex implant demonstrated sustained efficacy in treating refractory diabetic macular edema.
  • The crystalline lens remained stable for 12 months, indicating minimal impact on cataract progression.
  • Cataract extraction via phacoemulsification was performed uneventfully after 1 year, with continued resolution of macular edema post-surgery.

Implications:

  • This case represents the longest reported observation of an intralenticular Ozurdex implant.
  • Intralenticular placement of Ozurdex can be an effective treatment for refractory DME with limited cataractogenic potential.
  • Further research may explore the long-term safety and efficacy of intralenticular steroid implants in ophthalmology.
