Abstract
Background: To report the clinical features of patients with reverse pupillary block (RPB) after scleral-sutured posterior
chamber intraocular lens (PC IOL) implantation and biometric changes after laser peripheral iridotomy (LPI).
Methods: Eight patients attending our hospital’s ophthalmology outpatient clinic, who developed RPB after
implantation of a scleral-sutured PC IOL due to subluxation of the crystalline lens or IOL, were investigated in this
retrospective, observational study.
Results: Preoperative evaluations showed angle pigmentation in all cases and iridodonesis in 2 cases. Two subjects
had used an α1A-adrenoceptor antagonist for benign prostatic hyperplasia. Pars plana or anterior partial vitrectomy was
performed in all cases. All eyes showed an extremely deep anterior chamber, a concave iris configuration, and contact
between the IOL optic and the iris at the pupillary margin. Pupil capture was detected in 2 cases. The mean (± SD)
anterior chamber angle (ACA) was 89.91 ± 10.06°, and the anterior chamber depth (ACD) was 4.42 ± 0.16 mm before
LPI. After LPI, the iris immediately became flat with a decreased ACA (51.70 ± 2.59°; P = 0.018) and ACD (4.14 ± 0.15 mm;
P = 0.012). After LPI, the intraocular pressure decreased from 19.75 ± 3.77 mmHg to 15.63 ± 4.30 mmHg (P = 0.011), and
the spherical equivalent decreased from -0.643 ± 0.385 D to − 0.875 ± 0.505 D (P = 0.016).
Conclusion: Concomitant vitrectomy, angle pigmentation, and iridodonesis may be risk factors for RPB after
scleral-sutured PC IOL implantation. LPI is effective for relieving the RPB.
