Abstract

Purposes:

To describe a new technique of scleral tissue augmented cyanoacrylate tissue adhesive (CTA) application and to evaluate its efficacy in noninfectious corneal perforations that measure between 3.5 and 4.5 mm.

Methods:

Retrospective noncomparative case series included 16 consecutive patients diagnosed with moderate-sized corneal perforations measuring 3.5 to 4.5 mm who were treated with scleral patch graft augmented glue application. A partial-thickness scleral patch equal to the size of corneal perforation was placed in the corneal perforation site. After the area was sufficiently dried, CTA was applied on the interface of the host cornea and scleral patch. The ability of the scleral patch graft with CTA to seal the perforation and allow complete wound healing was considered a successful outcome.

Results:

The corneal perforation healed in 14 eyes (87.5%), with a mean of 5.65 weeks (range, 5–9 weeks). One eye (6.25%) developed microperforation that required additional CTA to seal the wound. Three eyes (18.75%) required reapplication of the scleral patch graft and CTA. The 2 eyes (12.50%) that failed scleral patch with CTA were successfully treated with tectonic penetrating keratoplasties. In all 5 eyes (100%), the corneal perforations as a result of Mooren ulcer healed in a mean 5.80 weeks (range, 5–7 weeks). One patient developed retinal detachment with proliferative vitreoretinopathy and cataract after trauma.

Conclusions:

Scleral patch graft augmented CTA technique is a successful alternative treatment method to emergent penetrating keratoplasty for corneal perforations that measure 3.5 to 4.5 mm.
