“…Pupil size may be associated with intraocular lens diameter and with night light glaring, blurring, decreased contrast sensitivity, and monocular diplopia, which are possible postoperative complications [ 1 ]. Especially in the field of refractive surgery, the correlation between pupil size and visual discomfort in a dark night environment after surgery is an important topic [ 15 ].…”

“…Generally, it is known that the larger pupil size in dark illumination, the more inconvenient night visual discomfort is after refractive surgery [ 16 ]. This suggests that the size of the scotopic or mesopic pupil size is more important than in the photopic state, clinically [ 1 ]. The present study is meaningful because it collected measurement values using the recent technique of Humphrey static perimetry, and took into consideration various factors related to pupil size in the clinically important mesopic condition.…”

BackgroundPupil size is an important factor in predicting post-operative satisfaction. We assessed the correlation between pupil size, measured by Humphrey static perimetry, and various affecting factors in patients with glaucoma.MethodsIn total, 825 eyes of 415 patients were evaluated retrospectively. Pupil size was measured with Humphrey static perimetry. Comparisons of pupil size according to the presence of glaucoma were evaluated, as were correlations between pupil size and various factors, including age, logMAR best corrected visual acuity (BCVA), retinal nerve fiber layer (RNFL) thickness, spherical equivalent, intraocular pressure, axial length, central corneal thickness, white-to-white, and the kappa angle.ResultsPupil size was significantly smaller in glaucoma patients than in glaucoma suspects (p < 0.001) or the normal group (p < 0.001). Pupil size decreased significantly as age (p < 0.001) and central cornea thickness (p = 0.007) increased, and increased significantly as logMAR BCVA (p = 0.02) became worse and spherical equivalent (p = 0.007) and RNFL thickness (p = 0.042) increased. In patients older than 50 years, pupil size was significantly larger in eyes with a history of cataract surgery.ConclusionsHumphrey static perimetry can be useful in measuring pupil size. Pupil size was significantly smaller in eyes with glaucoma. Other factors affecting pupil size can be used in a preoperative evaluation when considering cataract surgery or laser refractive surgery.
