Solid dermoids of the limbus and the cornea

Summary
Early surgical intervention for limbal and corneal dermoids, prioritizing simple excision, generally leads to good cosmetic and visual outcomes. Advanced cases may necessitate lamellar keratoplasty for optimal results.
Area of Science:
- Ophthalmology
- Surgical Oncology
- Corneal Surgery
Background:
- Limbal and corneal dermoids are congenital choristomas.
- These tumors can cause cosmetic concerns and visual impairment.
Purpose of the Study:
- To characterize limbal and corneal dermoids.
- To evaluate surgical outcomes and visual results.
Main Methods:
- Retrospective review of 12 patients with solid dermoids undergoing surgery (1985-1993).
- Surgical techniques included simple excision with conjunctival flap or corneoscleral lamellar keratoplasty.
Main Results:
- Simple excision improved cosmetic appearance with unchanged visual acuity in 6 cases.
- Refractive amblyopia persisted in 3 cases with late surgery.
- Early lamellar keratoplasty improved vision in 2 large dermoids.
- Amblyopia was the reason for early surgery in the corneal dermoid case.
Conclusions:
- Early surgical resection with conjunctival flap is often preferred over lamellar keratoplasty.
- Corneoscleral lamellar grafts are indicated for advanced cases involving full corneal thickness or extensive limbal extension.
