Abstract
Purpose :
To compare incidence of socket health outcomes between patients who underwent enucleation after eye trauma with patients who underwent enucleation due to non-traumatic indications. To identify risk factors associated with socket health complications after enucleation.
Methods :
A retrospective chart review was performed on patients who underwent enucleation by the oculoplastics service from January 2008-August 2017. Exclusion criteria were less than 18 years of age at time of enucleation, incomplete chart documentation, or less than 3 months of follow-up. Socket health complications were defined as enophthalmos, ptosis, implant exposure, deep eyelid sulcus, eyelid laxity granuloma, or inclusion cysts.
Data were summarized by mean (±standard deviation) or frequency (%) and compared between trauma and non-trauma using a two sample t-test or Fisher exact test. Kaplan-Meier survival analysis was used to estimate the elapsed time from enucleation to the first socket complication and compared between trauma and non-trauma groups using a log-rank test. Risk factors including age, sex, race, trauma, retrobulbar injections for pain, orbital fractures, number of pre-enucleation intraocular surgeries, size of orbital implant, and postoperative intraorbital hemorrhage were examined using stepwise Cox regression analysis.
Results :
62 patients were included. Average age was 42.5 (±16.0) years and 40 (65%) were male. Indications for enucleation included: 43 trauma (70%), 12 blind painful eye due to ocular diagnosis (19%), 5 perforation of eye (8%), and 2 burns (3%). No patients underwent enucleation for malignancy. 42 (67%) patients (32 [74%] trauma patients and 10 [53%] non-trauma patients [P=0.09]) experienced at least one socket complication. Of 42 socket complication patients, 22 (52%) were managed conservatively. The median survival time to a socket complication was found to be 6.3 months after enucleation for all patients, 5.9 months for trauma patients, and 13.2 months for non-trauma patients (P=0.26). Trauma patients were more likely than non-trauma patients to have socket contraction (P=0.05). However, incidence of socket complications was not associated with any risk factors studied.
Conclusions :
Although the incidence of socket complications in the trauma group was higher than the non-trauma group, the difference did not reach significance, which may due to the small sample size in the non-trauma group.
