Choroidal detachment in perforated corneal ulcers: frequency and management

Abstract

Choroidal detachment following corneal ulcer perforation is common and is more likely in larger corneal perforations. Preoperative B-scan should be considered in cases of large corneal perforations requiring therapeutic keratoplasty to document choroidal detachment, which if large may require drainage. Cyanoacrylate glue is an effective and safe method for sealing small corneal perforations. A vigil must be maintained for infection while the glue and bandage contact lens are in situ.

Tenons Patch Graft in the Management of Large Corneal Perforations

“…15 When a choroidal effusion is present, AC re-formation becomes difficult because of the positive posterior pressure. 16 Choroidal fluid drainage is advised in these conditions along with the procedure chosen to address the corneal perforation.…”

“…16 Choroidal fluid drainage is advised in these conditions along with the procedure chosen to address the corneal perforation. 15,16 The site of the choroidal drainage can be used to harvest the Tenons tissue required for the TPG procedure.…”

Tissue adhesives in ocular surgery

“…The combination of cyanoacrylate glue with a bandage contact lens and antibiotics can reduce the risk of infection, although corneal melting and reapplication of glue can be problematic in cases of large perforations [21].…”

PRECLUDE® Pericardial Membrane for the management of perforated corneal ulcer in patients with systemic autoimmune inflammation

“…Sie eignet sich eher für Deckung kleinerer nicht-perforierenden Ulzera, um eine bessere Wundheilung zu erzielen. Bei perforierten Hornhautulzera, die größer als 2 mm sind, ist die Amnionmembran nicht stabil genug [34]. Bei Ulzera, die größer als 3 mm sind, wurde Fibrinkleber verwendet, um die mehrschichtige Amnionmembran zu stabilisieren [14].…”
