Eyes with prior vitrectomy at risk for lens-iris diaphragm retropulsion syndrome
Eyes with prior vitrectomy had a high rate of lens-iris diaphragm retropulsion syndrome during phacoemulsification, according to a study.
The prospective, interventional case series comprised 75 eyes of 75 patients who underwent phacoemulsification after previous vitrectomy. Mean patient age was 65 years.
Lens-iris diaphragm retropulsion syndrome occurred in 40 eyes; 23 cases were mild, 13 cases were moderate, and four cases were severe. Thirty-five eyes showed no signs of lens-iris diaphragm retropulsion syndrome.
Severity of the syndrome significantly decreased with age (P = .001), whereas severity increased with increasing axial length (P < .001) and anterior chamber depth (P = .002). The association between severity and extent of vitrectomy was also a factor (P = .027), and men were at a significantly higher risk than women (P = .007).
