Khodadoust line

Khodadoust Line is a clinical sign observed in corneal transplantation, named after Dr. Irvine Khodadoust, a pioneer in the field of ophthalmology. It is a line of immune cells that migrate towards the corneal graft, indicating a rejection response.

Definition

The Khodadoust Line is defined as a line of leukocytes (white blood cells) that migrate towards a corneal graft in the event of a rejection response. This line is usually visible in the corneal endothelium, the innermost layer of the cornea. The presence of the Khodadoust Line is a significant indicator of graft rejection in corneal transplantation.

History

The Khodadoust Line is named after Dr. Irvine Khodadoust, an Iranian-American ophthalmologist who first described this clinical sign in 1970. Dr. Khodadoust's extensive research in corneal transplantation and graft rejection has significantly contributed to the field of ophthalmology.

Clinical Significance

The presence of the Khodadoust Line is a clear sign of graft rejection following corneal transplantation. It is one of the earliest signs of rejection and is often accompanied by other symptoms such as decreased vision, redness, and pain. Early detection of the Khodadoust Line allows for prompt treatment, which can significantly improve the prognosis of the graft.

Treatment

The primary treatment for a rejection response indicated by the Khodadoust Line is the administration of corticosteroids, either topically or systemically. In severe cases, additional immunosuppressive therapy may be required. Early detection and treatment are crucial to prevent irreversible damage to the graft.
