PURPOSE: There is anecdotal evidence that upper blepharoplasty might lead to raised intraocular pressure (IOP). If this association is confirmed, then patients with glaucoma and glaucoma suspects could be at risk if they underwent this procedure with no appropriate follow up. Here, the authors aimed to determine whether there are significant changes in IOP after upper blepharoplasty. METHODS: This prospective study evaluated the IOP at baseline and 1, 2, and 6 weeks after an upper blepharoplasty in individuals with mild to moderate dermatochalasis. Upper blepharoplasty might change the pressure exerted by the upper eyelid into the cornea, and this could affect the corneal surface and the IOP; thus, the corneal topography was also recorded before and at 6 weeks. RESULTS: The IOP of 40 eyes was evaluated. The mean (±SD) preoperative IOP was 14.19 ± 2.12 mm Hg. A statistically significant increase in IOP was observed at 1 (15.15 ± 2.27 mm Hg, p = 0.009), 2 (15.57 ± 2.29 mm Hg, p < 0.0001), and 6 weeks (15.21 ± 2.60 mm Hg, p = 0.001) postoperatively. A statistically significant increase in steep K (preoperative: 44.66 ± 2.06, 6 weeks: 44.78 ± 2.28, p = 0.007) and corneal astigmatism was also observed (preoperative: 0.78 ± 0.43, 6 weeks: 0.89 ± 0.45, p = 0.006) at 6 weeks. CONCLUSIONS: Upper blepharoplasty resulted in a mild and statistically significant increase in intraocular pressure postoperatively. The authors' results suggest that upper blepharoplasty should be carefully evaluated in glaucoma and glaucoma suspect patients.
