Purpose: Upper eyelid surgery may be associated with significant elevation in the intraocular pressure (IOP) levels exerted by the pressure of upper eyelid on the cornea. Increasing IOP is a well-known risk factor for glaucoma. This study evaluated the dynamic change of intraocular pressure and corneal curvature change in patients undergoing upper eyelid surgery to provide data to explore the need for early detection of patients with increased risk of glaucoma before undergoing eyelid surgical procedures.
Methods: A prospective observational study was conducted on seventeen patients (25 eyes in total) who were scheduled for upper eyelid surgery in one or both eyes. IOP measurements were taken at baseline and 2, 6, 12 weeks after upper eyelid surgery with an indication of ptosis and/or mild to moderate dermatochalasis.
Results: Data was collected from 25 eyes in 17 patients. 82% of the study group were females. Mean age was 58.92 ± 15.95 years. The mean baseline preoperative IOP was 13.20 ± 2.48 mmHg. There was no significant change in IOP and K1 (corneal curvature at 90 degrees) between baseline pre-and-postoperative IOP at 2, 6 and 12 weeks after surgery.

Conclusions: There is no significant change in variation of IOP or K1 steepening after upper eyelid blepharoplasty (P value > .05 in both comparative tests), within limitations of a small-sample sized study.
