Purpose:
To report factors affecting the retinal redetachment rate after silicone oil removal (SOR) following rhegmatogenous retinal detachment (RRD) repair.
Methods:
Retrospective cohort study from December 1, 2014, to March 1, 2020, of 205 consecutive patients treated for RRD with silicone oil (SO) tamponade and subsequent SOR with at least 6-month follow-up. Primary outcome measure was the rate of retinal redetachment after SOR.
Results:
The retinal redetachment rate after SOR was 18.5%. Preoperative macula and lens status, proliferative vitreoretinopathy, previous retinectomy, retinal detachment size, concomitant phacoemulsification, previous scleral buckling, and endolaser during SOR did not affect the redetachment rate after SOR. Previous SO exchange was associated with increased redetachment (OR 2.53, 95% CI [1.11–5.80], P = 0.0278). Twelve months of SO tamponade had lower redetachment rates compared with 3 months (OR 0.25, 95% CI [0.04–0.09], P = 0.048). Shorter SO tamponade (3 vs. 12 months) had better final visual outcomes after SOR (0.80 ± 0.61 vs. 1.41 ± 0.66, P
Purpose:
To quantitatively evaluate the inner and outer choroidal changes in the fellow eyes of patients with unilateral central serous chorioretinopathy (CSC).
Methods:
We analyzed data from patients with a diagnosis of unilateral CSC who had structural optical coherence tomography (OCT) and swept-source OCT angiography obtained. An additional group of age-matched healthy patients was included for comparison. The main outcome measures were: (1) choriocapillaris flow deficits’ quantitative metrics; (2) choroidal luminal (LCA) and stromal (SCA) areas; and (3) choroidal vascularity index.
Results:
Fellow unaffected eyes from 60 patients with unilateral CSC and 30 healthy subjects were included in the analysis. Mean ± SD age was 47.5 ± 9.9 years in the unilateral CSC group and 50.7 ± 10.8 years in the control group (P = 0.410). In the structural OCT assessment, both the LCA and SCA were increased in the unilateral CSC group (0.33 ± 0.11 and 0.29 ± 0.10 mm2) compared with healthy controls (0.28 ± 0.08 and 0.27 ± 0.05 mm2), although only differences in LCA reached a statistical significance (P = 0.041 and P = 0.286 for LCA and SCA, respectively). The choroidal vascularity index was higher in CSC patients (53.7 ± 3.6 and 50.9 ± 5.5%, P = 0.045). In the OCT angiography evaluation, the choriocapillaris flow deficits’ percentage and number were increased in those patients affected by unilateral CSC. In multiple regressions, the strongest association with choriocapillaris percentage of flow deficits was with the presence of pachychoroid pigment epitheliopathy signs in the study eye (P

Purpose:
To report 12-month visual outcomes, incidence of intraocular pressure (IOP) changes and postoperative complications after pars plana vitrectomy with retropupillary implantation of an iris claw intraocular lens (IOL) in aphakic eyes after complicated cataract surgery and eyes with a dislocation of the IOL.
Methods:
This is a retrospective analysis of eyes undergoing implantation of an iris claw IOL combined with pars plana vitrectomy from 1st of January 2009 until 30th of June 2018 after complicated cataract extraction with capsular loss (Group A) or dislocation of an IOL (Group B). Corrected distance visual acuity was analyzed in logarithm of the minimum angle of resolution (logMAR) units, IOP was recorded in mmHg.
Results:
Eyes in Group A (n = 49) improved from a preoperative median visual acuity of 0.523 logMAR (Snellen 20/65) to 0.201 logMAR (Snellen 20/30), P 0.05. During 12 months in Group A, IOP >21 mmHg occurred in 9 (18.4%) eyes; no eye had an IOP 21 mmHg occurred in 15 (11.9%) eyes, IOP 21 mmHg or

Purpose:
To assess retinal microvascular alterations in individuals with amnestic mild cognitive impairment (MCI) and nonamnestic MCI.
Methods:
One hundred twelve eyes of 59 amnestic MCI participants, 32 eyes of 17 nonamnestic MCI participants, and 111 eyes of 56 controls with normal cognition were included. Optical coherence tomography angiography vessel density and perfusion density in the Early Treatment Diabetic Retinopathy Study 3-mm circle and ring were assessed. Retinal thickness parameters including retinal nerve fiber layer thickness, ganglion cell-inner plexiform layer thickness, central subfield thickness, and subfoveal choroidal thickness were also analyzed. Multivariable generalized estimating equations were used for statistical analysis.
Results:
Perfusion density in the 3-mm inner ring was significantly lower in amnestic MCI patients when compared with nonamnestic MCI participants (0.29 ± 0.03 vs. 0.34 ± 0.09, P = 0.025) and controls with normal cognition (0.29 ± 0.03 vs. 0.39 ± 0.02, P
