Abstract
Purpose To examine changes in parameters of the visual field test before and after blepharoptosis surgery in patients with glaucoma. Methods Twenty-three eyes of 14 glaucoma patients who underwent blepharoptosis surgery at Toyama University Hospital between July 2015 and September 2020 were included in this study. Pre- and post-operative values for the mean deviation (MD), pattern standard deviation (PSD) and total deviation (TD) of the upper or lower hemi-visual field in the Humphrey visual field test, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and margin reflex distance (MRD)-1 were compared. Results MRD-1 showed a significant improvement after blepharoptosis surgery (preoperative MRD-1: 1.0 ± 0.82 mm, postoperative MRD-1: 3.26 ± 0.66 mm, p < 0.001). There were no significant differences in BCVA, IOP, MD and PSD values before and after surgery. On the other hand, there was a significant improvement in the superior TD (preoperative: −11.29 ± 6.57 dB, postoperative: −9.88 ± 7.31 dB, p = 0.044) although no significant difference was detected in the inferior TD postoperatively. The preoperative parameters of 2 groups (improvement and non-improvement groups of postoperative superior TD) were compared. Preoperative MD and superior TD were significantly lower in the improvement group (p = 0.03, p = 0.004, respectively), although there was no significant difference in preoperative PSD and inferior TD between the two groups. Conclusion In glaucoma patients, blepharoptosis may interfere with accurate visual field assessment, especially of superior TD.
