PURPOSE: To describe the incidence, complications and management of reverse pupillary block (RPB) after implantation of Carlevale intraocular lens (IOL).
DESIGN: Multicenter, retrospective, cross-sectional study.
PARTICIPANTS: Of a sample of 128 patients that had undergone Carlevale IOL implantation, 19 patients were found to present RPB.
METHODS: Nineteen patients with RPB after Carlevale IOL implantation were evaluated and treated with laser peripheral iridotomy (LPI).
MAIN OUTCOME MEASURES: Demographic data (age and gender), data on preexisting medication, axial length (Zeiss IOLMaster 500 and Zeiss IOLMaster 700), presence of pseudoexfoliation material, presence of RPB (anterior segment swept-source SS-OCT Anterion, Heidelberg Engineering), presence of macular edema (Irvine Gass syndrome, OCT Spectralis, Heidelberg Engineering), anterior chamber depth (ACD) before and after LPI, best-corrected visual acuity (BCVA) before and after LPI, and intraocular pressure (IOP) before and after LPI were analyzed.
RESULTS: An incidence of RPB of 14.8% was found. The prevalence of pseudoexfoliation syndrome was 21.1%, and 42.1% of patients presented an axial length >24.00 mm. Mean pre-LPI ACD was 4.78 ± 0.465 mm and post-LPI ACD was 4.23 ± 0.404 mm, a statistically significant increase of 0.54 mm (P < 0.001; 95% confidence interval, 0.26-0.83) of ACD was observed. There were no differences between pre- and post-LPI BCVA. Pre-LPI IOP was 17.10 (range, 12-34) mmHg and post-LPI IOP was 14.47 (range, 10-21) mmHg, (P = 0.391). Cystic macular edema (Irvine Gass) was identified in 4 of 19 patients, reporting an incidence of 21.1% in RPB cases.
CONCLUSIONS: Reverse pupillary block is a relatively common complication after Carlevale lens implantation, which may be associated with an increase of macular edema incidence but does not clearly correlate an increase of IOP. Our hypothesis is that indentation of the sclera induces a posterior rotation of the peripheral iris, causing RPB. Our results encourage looking over the Carlevale IOL implantation technique to consider a routinely intraoperative surgical peripheral iridotomy to avoid RPB and its further complications.
