[Recalcitrant cicatrizing conjunctivitis. Treatment of nine patients with rituximab].

Cicatrizing conjunctivitis is the final consequence of several diseases. The most severe among them are cicatricial pemphigoid and chronic Stevens-Johnson syndrome. Systemic immunosuppressive drugs and steroids are usually an effective approach to these diseases.

Peripheral Reconstructive Lamellar Keratoplasty for Late Ectasia After Penetrating Keratoplasty in Keratoconus Eyes.

Purpose: To describe outcomes of customized peripheral anterior lamellar keratoplasty (PALK) for late ectasia of the donor-recipient junction after penetrating keratoplasty (PK) for keratoconus.

Methods: This was a single-center, retrospective review of 33 eyes (28 patients) that developed ectasia restricted to the graft-host junction; 17 eyes underwent PALK using lamellar resections of 8- to 11-mm width starting at the external margin of the previous PK and suturing a same-size donor graft (annular or segmental). Five eyes were excluded from analysis because of postoperative complications unrelated to the technique.
