Abstract Details

Purpose:

To describe a post-penetrating-keratoplasty (PKP) case receiving emergent evisceration and silicon sphere implantation due to non-traumatic eyeball rupture with severe uvea prolapse.

Setting:

Taipei City Hospital, Taipei, Taiwan

Methods:

A case report.

Results:

A 80 year-old female case received PKP twice 30 years ago due to right eye leucoma cornea. In 2014, her right eye revealed graft failure and thinging, limbal deficiency, secondary glaucoma and pseudophakia. In April 2018, unforeseen prolapsed uvea was noted over corneal perforation aperture of her right eye without trauma and surrounding corneal tissue was almost unidentified. She underwent evisceration with silicon sphere implantation. Two months later, deep superior sulcus syndrome and orbital implant exposure developed, so she received orbital reconstruction with dermis-fat graft. The risk factors of implant exposure, its management and orbital reconstruction will be discussed.

Conclusions:

The risk of severe eyeball rupture in the cornea with tectonic vulnerability, such as post-penetrating-keratoplasty graft failure and thinning in this case, should be noted. Orbital implant exposure may be the most common complication after evisceration surgery. Several methods have been described for its management. Our experience using dermis-fat graft for implant exposure and orbital reconstruction revealed satisfactory cosmetic outcomes.
