Summary

Triamcinolone acetonide (TA) aids in visualizing the internal limiting membrane (ILM) during macular hole surgery. Histopathology confirmed the ILM was successfully peeled, improving patient vision without adverse effects.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Histopathology

Background:

  • Macular hole repair often involves internal limiting membrane (ILM) peeling.
  • Visualizing the ILM during surgery can be challenging.
  • Triamcinolone acetonide (TA) is an anti-inflammatory corticosteroid.

Observation:

  • TA suspension was used to enhance ILM visualization in a patient undergoing macular hole repair.
  • The peeled area of the ILM appeared distinct, lacking white specks after TA application.
  • The macular hole successfully closed, leading to improved visual acuity.

Findings:

  • Histopathologic examination of the surgical specimen confirmed the presence of the internal limiting membrane (ILM).
  • Triamcinolone acetonide significantly improved the intraoperative visualization of the ILM.

  • No adverse events were noted during the postoperative follow-up period.

    • Implications:

    • The use of TA facilitates ILM peeling during macular hole surgery.
    • This technique allows for microscopic confirmation of ILM removal.
    • TA may enhance surgical outcomes in macular hole repair by improving ILM visualization.
