Functional and anatomical outcomes of fovea on, fovea off and fovea-splitting rhegmatogenous retinal detachment.

PURPOSE: To compare the anatomical and functional outcomes of fovea-on, fovea-off, and fovea-split rhegmatogenous retinal detachment (RRD). METHODS: Retrospective case series of consecutive patients diagnosed with RRD and treated with only pars plana vitrectomy (PPV). Preoperative and postoperative optical coherence tomography (OCT) and functional outcomes were obtained prior to and 6 months after surgery. RRD extending to the edge of the fovea on OCT was termed fovea-split RRD. RESULTS: A total of 152 eyes were included, out of which 89 eyes presented with a fovea-off, 36 with a fovea-on, and 27 with a fovea-split RRD. The mean visual acuity (VA) preoperatively was 1.32 ± 0.58 logMAR (20/400 equivalent on Snellen chart), 0.19 ± 0.20 (20/30), and 0.71 ± 0.56 (20/100) for the fovea-off, fovea-on, and fovea-split groups, respectively (p < 0.001). The mean VA at 6 months of follow-up significantly improved for the fovea-split and fovea-off groups to 0.54 ± 0.79 (20/70) (p < 0.001) and 0.45 ± 0.29 (20/50) (p = 0.01), respectively, and remained stable for the fovea-on group 0.24 ± 0.20 (20/30) (p = 0.25). Differences in alterations of the outer retinal layers (p < 0.001) and in the in-segment/outer-segment ratio (p < 0.001) were found between the groups. CONCLUSION: Eyes with fovea-split RRD had both a preoperative and a final postoperative VA between those of fovea-on and fovea-off eyes and different anatomical changes on OCT. This new entity warrants different patient expectations for postoperative outcomes.

Postponed care due to COVID-19 lockdown impact on visual acuity of retinal vein occlusion patients: a large cohort.

PURPOSE: To evaluate the impact of postponed care attributed to coronavirus disease (COVID-19) pandemic lockdowns on visual acuity and the number of anti-VEGF injections in patients with retinal vein occlusion (RVO). METHODS: A multicenter, retrospective study of consecutive RVO patients previously treated with anti-VEGF injections, which compared data from pre- (2019) and during (2020) COVID-19 lockdown period. RESULTS: A total of 814 RVO patients with a mean age of 72.8 years met the inclusion criteria. Of them, 439 patients were assessed in 2019 and 375 in 2020. There was no significant difference between the COVID-19 and pre-COVID-19 period in terms of baseline and final BCVA (p = 0.7 and 0.9 respectively), but there was a significantly reduced mean number of anti-VEGF injections during the COVID-19 period (5.0 and. 5.9 respectively, p < 0.01), with a constant lower ratio of injections per patient. A noticeable decline was found during March-May (p < 0.01) in 2020. Baseline BCVA (0.69, p < 0.01) and the number of injections (- 0.01, p = 0.01) were predictors of final BCVA. CONCLUSIONS: In a large cohort of RVO patients, during 2020 lockdowns imposed due to the COVID-19 pandemic, a significant reduction in the annual number of anti-VEGF injections was noted. The postponed care did not result in a significant impact on the final BCVA. Baseline BCVA and the number of annual injections serve as predictors for final BCVA in RVO patients.

Maternal urinary tract infection during pregnancy and long-term infectious morbidity of the offspring.

BACKGROUND: Urinary tract infection (UTI) is a common bacterial infection in pregnant women and is associated with adverse perinatal outcomes. We sought to investigate the long-term infectious outcomes of children to mothers who were diagnosed with UTI during their pregnancy. METHODS: A population-based cohort analysis was conducted at a single tertiary medical center. The study included all singleton deliveries between the years 1991-2014, comparing offspring born to mothers diagnosed with UTI during their pregnancy with those born to non-exposed mothers. Infectious-related hospitalizations of the offspring up to the age of 18 years were assessed according to a predefined set of ICD-9 codes. A Kaplan-Meier survival curve was conducted to compare cumulative hospitalization incidence between the groups. A Cox regression model was used to adjust for confounders. RESULTS: During the study period, 243,725 deliveries met the inclusion criteria. Of them, 8034 (3.3%) were exposed to maternal UTI during pregnancy. Infectious-related hospitalizations were significantly prevalent in offspring to exposed mothers (12.3% vs. 11.0%, OR = 1.125, 95% CI 1.051-1.204, Kaplan-Meier log rank p < 0.001). In the Cox regression model, while controlling for clinically relevant confounders, maternal UTI (adjuster HR = 1.240), as well as preterm delivery (adjusted HR = 1.385) and cesarean delivery (adjusted HR = 1.198) were noted as independent risk factors for long-term infectious morbidity of the offspring. CONCLUSIONS: Maternal UTI in pregnancy may influence offspring susceptibility to pediatric infections, as it was found to be an independent risk factor for long-term infectious morbidity of the offspring.
