Introduction: Asymmetrical eyelid skin crease may be mistaken for ptosis due to apparent narrowing of the palpebral fissure in the eye without the skin crease. This study describes a series of patients who were mistakenly referred for ptosis operation as a result of absent skin crease.
Methods: Retrospective case review.
Results: A total of 8 patients (5 males and 3 females) were referred by the general ophthalmologists because of suspected ptosis. Although skin creases asymmetry was noted by the general ophthalmologists, the apparent narrowing of the palpebral fissure was thought to be caused by ptosis. However, measurement of the palpebral fissures in both eyes were normal. Creation of a symmetrical skin crease in the affected eye correct the appearent palpebral fissure narrowing. This could be achieved by either surgical or non-surgical means (tape or glue).
Conclusion: Patients with asymmetrical skin crease of the upper eyelid can give rise to apparent differences in palpebral apertures which may be mistaken for ptosis. The treatment of choice is to create symmetrical skin crease in the eye with absent skin crease to correct the pseudoptosis. Recognition of this condition is important to avoid unnecessary ptosis surgery.
