Purpose:
To evaluate the effect of axial globe projection on lower eyelid malposition with aging.
Methods:
Consecutive patients presenting to 2 oculoplastic surgeons with lower eyelid and tarsal involutional ectropion or entropion underwent axial globe projection measurements with a Hertel exophthalmometer.
Results:
Data on 36 eyelids of 31 white patients were collected. Axial globe projection in the ectropion group, mu = 19.9, was significantly greater than in the entropion group, mu = 16.1 (p = 0.000021). This held true even when the analysis was confined to the subgroup of male patients.
Conclusion:
Tarsal ectropion directly correlates with more prominent axial globe position, and patients with relatively enophthalmic eyes tend to develop entropion.
