SE during convergence in both groups (P < 0.05).ConclusionInsufficient accommodation and pupil constriction during near viewing were observed in patients with IXT who had complaints of blurred vision or asthenopia from near viewing. These conditions might contribute to symptoms, such as fatigue, eye...
and confirmed and extended the clinical observations. Abnormalities were only detected inBmp4+/-mice. The severity of lesions varied within individual eyes and between eyes of the same mouse. In most eyes, the iridocorneal angle was abnormal. The iridocorneal angle contains the ocular drainage s...
Pupil-diameter and pupil-constriction ratios were also compared between patients and healthy subjects, and the correlation of constriction ratio with increment SE was calculated for both groups. Results Compared to healthy subjects, IXT patients demonstrated significantly lower increment SE of convergence ...
