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.
