|dc.description.abstract||PURPOSE: To evaluate long-term changes in tear volume by using video meniscometry following blepharoptosis surgery and upper blepharoplasty. METHODS: Forty-three eyes of 27 patients with blepharoptosis and 29 eyes of 18 patients with dermatochalasis without lacrimal duct obstruction or other eyelid diseases underwent anterior approach levator advancement or blepharoplasty. Tear volume was evaluated by measurement of tear meniscus radius (R), using video meniscometry preoperatively and at 1.5, 3, and 6 months postoperatively. Margin reflex distance-1 (MRD-1) was measured before and after surgery by using photographs. RESULTS: After blepharoptosis surgery, the mean MRD-1 was significantly increased: 0.45 mm preoperatively, 3.64 mm at 1.5 months, 3.56 mm at 3 months, and 3.57 at 6 months postoperatively (P < 0.001), and the average R value was significantly decreased: 0.29 mm preoperatively, 0.22 mm at 1.5 months, 0.23 mm at 3months, and 0.24 mm at 6 months postoperatively (P < 0.05). Preoperative R was significantly correlated to the reduction rate of R (ΔR). A higher preoperative R was more likely to be decreased (P < 0.01). Postoperative MRD-1 and change in MRD-1 were not correlated to ΔR. After blepharoplasty, the preoperative mean MRD-1 (3.11 mm) was significantly decreased at 1.5 months (2.47 mm; P < 0.01) and 3 months (2.71 mm; P < 0.05) but recovered at 6 months (3.14 mm). However, the average R was not changed: 0.31 mm preoperatively, 0.34 mm at 1.5 months, 0.31 mm at 3 months, and 0.33 mm at 6 months postoperatively. CONCLUSIONS: Long-term tear volume was not changed after blepharoplasty but was decreased after blepharoptosis surgery, and even more so in cases with an initial high tear volume.||en|
