A ring dermoid of the cornea is a rare congenital eye condition in which a ring-shaped mass of tissue containing skin, hair, and fat is present in the cornea. It is usually located in the center of the cornea and can cause vision problems if it is large enough to interfere with the normal curvature of the cornea. Treatment usually involves surgical removal of the dermoid.

The symptoms of a ring dermoid of the cornea include:

-A visible ring-shaped lesion on the cornea

-Blurred vision

-Sensitivity to light

-Pain or discomfort in the eye

-Redness of the eye

-Tearing or discharge from the eye

-A feeling of something in the eye

Ring dermoid of the cornea is a congenital condition, meaning it is present at birth. It is caused by a defect in the development of the cornea during fetal development. The exact cause of this defect is unknown, but it is thought to be related to genetic factors.

The treatment for a corneal ring dermoid typically involves surgical removal of the lesion. This is usually done with a procedure called a corneal lamellar keratoplasty, which involves removing the affected area of the cornea and replacing it with a healthy donor cornea. In some cases, a corneal transplant may be necessary. In addition, topical steroid drops may be prescribed to reduce inflammation and help the healing process.
