Orbital implant exposure following enucleation or evisceration.

Abstract

PURPOSE:To study the exposure rate of orbital implant postenucleation or evisceration procedures in two tertiary hospitals in Oman.DESIGN:A retrospective, descriptive, cross-section study.MATERIALS AND METHODS:Patients' records were reviewed for patients' demographics, surgical indications, implant types, follow-up and any reported complications after surgeries. Patients with a minimum of 1 year follow-up period were selected. All patients who underwent enucleation or evisceration with primary orbital implant were included in the study. Patients who underwent secondary orbital implant were excluded from the study.RESULTS:A total of 37 patients (age between 4 and 88-year-old, median age is 54-year-old) underwent enucleation or evisceration during 2008–2014. The most common indications for the surgical intervention were painful blind eye (35%), followed by trauma (16%), and perforated corneal ulcer (16%). Out of 37 patients, hydroxyapatite implant was implanted in 17 patients (46%), a glass or acrylic implant was implanted in 17 patients (46%), bioceramic implant was implanted in two patients (5%), and Molteno prosthesis was implanted in one patient (3%). There was no case of orbital implant exposure in any patients in this study.CONCLUSIONS:No orbital implant exposure was recorded in this study. The surgical technique, end to end rectus muscles suturing, used for enucleation/evisceration was the main reason for reduced implant exposure. In addition, the preexisting ocular pathology did not affect the outcome of the study.
