Excision of unilateral epibulbar limbal dermoids improved cosmetic appearance and visual acuity in patients. While surgical complications occurred, the benefits of dermoid removal outweigh the risks for carefully selected individuals.

Area of Science:

  • Ophthalmology
  • Ocular Oncology
  • Dermatology

Background:

  • Epibulbar limbal dermoids are congenital choristomas that can affect ocular health and appearance.
  • These benign tumors present a cosmetic concern and can cause visual impairment due to astigmatism or obstruction.

Purpose of the Study:

  • To evaluate the cosmetic and visual outcomes of surgical excision for unilateral epibulbar limbal dermoids.
  • To assess the incidence and nature of postoperative complications associated with this procedure.

Main Methods:

  • Retrospective review of clinical files for 10 patients who underwent excision of unilateral epibulbar limbal dermoids.
  • Analysis of pre- and postoperative visual acuity and astigmatism measurements.
  • Documentation of cosmetic improvement and surgical complications.

Main Results:

  • Preoperatively, affected eyes showed significantly worse visual acuity (P < .02) and increased astigmatism (P < .01) compared to contralateral eyes.
  • All patients experienced cosmetic improvement post-surgery.
  • Of eight patients with available data, six had minimal change (<1 line) and two had improved visual acuity (<2 lines) postoperatively.
  • Common complications included persistent epithelial defects (40%) and peripheral corneal vascularization/opacity (70%).

Conclusions:

  • Surgical excision of unilateral epibulbar limbal dermoids offers significant cosmetic benefits.
  • Visual acuity may remain stable or slightly improve in most cases.
  • Despite potential complications like epithelial defects and corneal changes, the procedure is beneficial for selected patients seeking improved cosmesis and visual function.
