Enucleation and evisceration:indications, complications and clinicopathological correlations

AIM

To assess main indications, postoperative complications and clinicopathological correlation of ocular enucleation-evisceration.

METHODS

A total of 107 subjects who underwent enucleation and/or evisceration and received hydroxyapatite implants (Scleral wrap or mesh) were assessed. For each patient clinicopathological data was collected which included demographic information, clinical history, primary clinical diagnosis, main cause of ophthalmic surgery (traumatic, non-traumatic), type of surgical procedure (enucleation, evisceration) and pathological report. Patients'' postoperative clinical visits were checked for procedure-related complications during first year after surgery.

RESULTS

One hundred and seven patients (male: 65.4%; mean age: 26y) underwent enucleation (n=100) or evisceration (n=7) due to traumatic (n=41) and non-traumatic (n=66) causes. Disfiguring painful blind eye was the most common indication of surgery (66.4%), followed by leukocoria (19.6%) and endophthalmitis (4.7%). The main types of injury included firecracker, traffic and work accidents, and sharp object perforating injury. In 53 (80.3%) subjects in non-traumatic group the initial clinical diagnosis matched the histopathological results. Malignant tumors (retinoblastoma: 47.5%, malignant melanoma: 27.3%) were the most common pathological diagnoses followed by phthisis bulbi (25.8%). The most common procedure-related complications were major eye discharge (39.6%), and implant exposure and discharge (20.8%).

CONCLUSION

Trauma and malignant tumors are the leading causes of enucleation-evisceration. Despite developing new techniques and materials, enucleation is still associated with considerable postoperative complications.
