Purpose: To report a case of corneal hydrops in a patient with keratoglobus that was managed with endothelial keratoplasty to achieve corneal stability and prevent a limbus-to-limbus tear in Descemet membrane.
Methods: A 30-year-old man with keratoglobus presented with corneal hydrops in his left eye resulting from a central vertical tear in Descemet membrane. His other eye had been previously treated with penetrating keratoplasty using a large graft (an 11-mm donor graft to a 10-mm recipient bed) because of a limbus-to-limbus tear in Descemet membrane without resolution of his edema. An attempt to approximate the edges of the Descemet tear in the left eye by an intracameral air injection failed, and the tear continued to progress peripherally. An endothelial keratoplasty button with anchoring sutures was placed over the Descemet tear because of excessive localized edema.
Results: One month after insertion of the sutured endothelial keratoplasty button, the edema had resolved, and 1 year later, the tear remains sealed. The patient's visual acuity improved from counting fingers at 1 foot to 20/100.
Conclusions: Reconstitution of the posterior corneal surface in keratoglobus-induced hydrops can be achieved with endothelial keratoplasty over the Descemet tear. Preventing progression of a central Descemet tear is essential to bypass the need for a large-diameter penetrating keratoplasty graft and its complications in a young patient with a history of bilateral corneal hydrops.
