To determine how often patients referred for unilateral lower eyelid entropion or ectropion repair develop the same condition in the fellow eye requiring surgical intervention.
A retrospective chart review was performed of patients referred to the office of a single oculoplastic surgeon and underwent surgical intervention for the diagnosis of unilateral involutional entropion or involutional ectropion from November 1, 2005 to October 31, 2014. Data collected included patients age, ethnicity, sex, smoking history, past ocular history, referral date, referral diagnosis, laterality, bilateral eye exam, initial surgical date, surgical eye, date of subsequent referral, subsequent referral diagnosis, laterality, and subsequent surgery date.
A total of 215 charts were reviewed, of which, 97 (45%) met inclusion criteria of unilateral surgery. Of the 97 patients, 76 had ectropion (78%) and 21 had entropion (22%). Forty (44%) were female and 54 (56%) were male. All of the patients were Caucasian After 148 months of follow up, 9 out of 97 patients in the ectropion group (11.8%) required surgery on the second eye. and 5 out of the 21 patients in the entropion group (23.8%) required surgery on the second eye. Although not statistically significant, the trend showed patients with entropion to require surgical intervention on the subsequent eye sooner than those with ectropion (at 12 months, 1.9% ectropion vs. 6.4% of ectropion). There was no increased likelihood for surgery on the fellow eye based on age, sex, smoking history, the type of involutional change, and severity of the disease.
In patients requiring surgical repair of unilateral entropion or ectropion, there is no identifiable time frame for having surgery on the fellow eye. Although not statistically significant, those patients presenting with unilateral entropion were more likely to require surgical intervention on the fellow eye, and to develop involvement of the fellow eye earlier compared to patients with ectropion. Also, key patient characteristics and environmental factors were not shown to influence an increased likelihood for surgery in the fellow eye. Larger, prospective studies may further identify risk factors predisposing to the development of bilateral entropion and ectropion.
