Acrylic intraocular lenses (IOLs) are easier to insert than foldable lenses of other materials. In addition to material properties, the structure of acrylic lenses allows an optimal folding angle along the 10 to 4 o'clock axis. Folding the IOL along this axis simplifies the manipulation of the leading haptic during insertion and places the trailing haptic within the capsular bag before the folded optic is released.
To evaluate the clinical course of patients with neovascular age-related macular degeneration (nAMD) after developing endophthalmitis during their treatment with intravitreal injections.Multicenter, retrospective series.From April 2013 to October 2018, 196,598 intravitreal anti-vascular endothelial growth factor (VEGF) injections were performed, with 75 cases of endophthalmitis (incidence 0.0381%). There was no association between intravitreal anti-VEGF drug (P = 0.29), anesthetic method (P = 0.26), povidone concentration (P = 0.22), or any intraprocedure variable and endophthalmitis incidence. Seventy-two patients (96%) were treated with intravitreal tap and inject , while 3 underwent immediate pars plana vitrectomy. After endophthalmitis resolution, 17 patients (22.7%) were not re-treated for nAMD (in 10 cases due to inactive disease; follow-up, 115 ± 8.4 weeks). Patients required less frequent anti-VEGF injections after infection (7.4 ± 0.61 weeks vs. 11.5 ± 1.8 weeks; P = 0.004). Preinfection logarithm of the minimum angle of resolution visual acuity was 0.585 ± 0.053 (∼20/77). It worsened with endophthalmitis (1.67 ± 0.08, ∼20/935; P < 0.001) and again on postendophthalmitis treatment day 1 (1.94 ± 0.064; count fingers; P < 0.001), but improved after reinitiating nAMD therapy (1.02 ± 0.11; ∼20/209; P < 0.001). Better visual acuity on postendophthalmitis week 1 (P = 0.002) and reinitiation of nAMD treatment (P = 0.008) were associated with better final visual acuity, and streptococcal culture with worse visual acuity (P = 0.028). The postendophthalmitis treatment interval was associated with the anti-VEGF drug used (aflibercept = ranibizumab > bevacizumab; P < 0.001).Patients with nAMD required fewer injections after endophthalmitis, suggesting a biological change in disease activity. Neovascular age-related macular degeneration became quiescent in 13.3% of eyes. Most achieved better outcomes with anti-VEGF reinitiation.
Purpose To study and compare the findings on multifocal electroretinography (MERG) between multifocal choroiditis (MFC) and the multiple evanescent white dot syndrome (MEWDS). Subject and Methods Patients were recruited prospectively from the Department of Ophthalmology & Visual Sciences at the University of Iowa Hospitals & Clinics. They were evaluated using Goldmann visual fields (GVF) and MERG. Patients were diagnosed as having either MFC or MEWDS based on their clinical findings before MERG testing. Results Nineteen patients (23 eyes) were included in the study. Eleven patients were diagnosed with MFC and eight patients with MEWDS. Fourteen eyes with MFC and seven eyes with MEWDS were tested with MERG during the acute phase of their respective conditions. Fourteen patients (8 MFC and 6 MEWDS) were followed serially with MERG. Patients with MEWDS demonstrated focal depression corresponding to GVF defects with subsequent near total recovery of the MERG to baseline. Patients with MFC typically demonstrated diffuse loss of function over the entire test field. Focal scotomata, in addition to the diffuse depression, could be identified in 7 of 14 patients. Patients with MFC demonstrated only partial or no recovery of MERG following acute episodes, which was significantly different from the course followed by patients with MEWDS (P < 0.001, Fisher’s exact test). Conclusion Multifocal electroretinography differentiates MFC from MEWDS. Patients with MFC have permanent damage to the retina with diffuse depression of MERG. Patients with MEWDS, however, typically demonstrate greater focal loss initially on MERG followed by nearly full recovery of first order retinal function.
