Determining factors involving Health worker Load throughout Early-Onset Dementia.
To assess whether early visual acuity letter score change from baseline (ΔVALS) and early spectral domain optical coherence tomography (SD-OCT) measures of center point thickness (CPT) are associated with later ΔVALS in eyes with macular edema due to central or hemiretinal vein occlusion treated with intravitreal aflibercept or bevacizumab.

Secondary analysis of a randomized clinical trial of 362 participants.

Considered separately at month 3, CPT (categorized as ≤ 300μm, > 300μm) and ΔVALS (categorized as < 5, 5-9, ≥ 10) are predictive of ΔVALS at month 6 (aflibercept P = 0.02 for CPT and P < 0.0001 for ΔVALS; bevacizumab P = 0.007 for CPT and P < 0.0001 for ΔVALS) and, except for CPT in thebevacizumabarm, also predictive of ΔVALS at month 12 (aflibercept P = 0.03 for CPT and P < 0.0001 for ΔVALS; bevacizumab P = 0.18 for CPT and P < 0.0001 for ΔVALS). Month 3 predictors are also associated with average ΔVALS from months 4 to 12 (CPT P = 0.01 in theafliberceptarm, P = 0.02 in thebevacizumabarm; ΔVALS > 10 versus < 5; P < 0.001 for both aflibercept and bevacizumab). When month 3 measures are considered jointly, ΔVALS effect remains significant for average ΔVALS from months 4 to 12 (aflibercept P = 0.002; bevacizumab P < 0.0001) but not CPT (aflibercept P = 0.18; bevacizumab P = 0.22).

While both month 3 ΔVALS and CPT are predictive of ΔVALS after month 3 through month 12, early ΔVALS has a stronger relationship than CPT with later ΔVALS. SCORE2 registration number is NCT01969708.

The aim of the present cross-sectional real-world study is to evaluate the impact of switch of anti-VEGF agent from ranibizumab to aflibercept on visual acuity, treatment frequency and retinal morphology after 12 months in eyes with ongoing chronic treatment for wet age-related macular degeneration (AMD) compared to eyes not subjected to switch of anti-VEGF agent.

Data was obtained retrospectively from the Swedish Macular Register, spectral-domain optical coherence tomography (OCT) images and electronic patient charts. All eyes included were treated in the same clinical setting at the Department of Ophthalmology at the county hospital of Västmanland in Västerås, Sweden.

In total, 282 and 359 eyes were included in the non-switch and switch cohorts, respectively. The cohorts were well balanced. Visual acuity remained stable during the observation period in both cohorts of eyes. EPZ5676 The number of anti-VEGF treatments slowly declined over time in both cohorts of eyes and, consequently, the treatment intervals idings suggest a beneficial effect of switching from ranibizumab to aflibercept in eyes with ongoing chronic anti-VEGF treatment irrespective of previous response to ranibizumab. Longer follow-up is required to further evaluate the potential clinical significance of this finding.
To study whether there is a correlation between the macular and optic nerve morphological condition and the retinal ganglion cells (RGCs) and visual pathways' function, and to investigate whether visual acuity (VA) changes might be related to the morpho-functional findings in chronic non-arteritic ischemic optic neuropathy (NAION).

In this retrospective study, 22 patients (mean age 62.12 ± 6.87) with chronic unilateral NAION providing 22 affected and 22 fellow eyes without NAION (NAION-FE), and 20 (mean age 61.20 ± 7.32) healthy control subjects were studied by spectral domain optical coherence tomography (Sd-OCT) for investigating macular thickness (MT) and volume (MV) of the whole (WR), inner (IR) and outer retina (OR), and the peripapillary retinal nerve fiber layer thickness (RNFL-T) measured overall and for all quadrants. Also, simultaneous 60' and 15' pattern electroretinogram (PERG) and visual evoked potentials (VEP) and VA were assessed. Differences of MT and MV of WR, IR, OR, and RNFL-T overall aesponding values of 60' and 15' VEP A were also found.

Our findings suggest that in chronic NAION, there is a morpho-functional impairment of the IR, with OR structural sparing. VA changes are related to the impaired morphology and function of IR, to the temporal RNFL-T reduction and to the dysfunction of both large and small axons forming the visual pathway.

Reduced gray-white matter contrast along the central sulcus has been described on T1- and T2-weighted magnetic resonance imaging (MRI). The purpose of this study was to assess the gray-white matter contrast of the motor cortex on double inversion recovery (DIR), a sequence with superior gray-white matter differentiation.

The gray-white matter signal on DIR was retrospectively compared to T1-weighted magnetization-prepared rapid gradient echo (T1-MPRAGE) using normal (n= 25) and abnormal (n = 25) functional MRI (fMRI) exams. Quantitative gray-white matter contrast ratios (CR) of the precentral and adjacent gyri were obtained on normal exams. Two neuroradiologists qualitatively rated reduced gray-white matter contrast of the hemispheres of both normal and abnormal exams. Hand motor functional mapping was used as a reference.

In normal hemispheres (n= 50), the mean CR was significantly lower on DIR (0.44) vs T1-MPRAGE (0.63, p< 0.001). Reduced gray-white matter contrast was categorized as "definitely present" more frequently on DIR than T1-MPRAGE by reviewers in both normal (n = 50; reviewer 1 DIR 88% and MPRAGE 68%, p= 0.02; reviewer 2 DIR 86% and T1-MPRAGE 64%; p=0.01) and abnormal hemispheres (n = 50; reviewer 1 DIR 80% and T1-MPRAGE 38%, p < 0.001; reviewer 2 DIR 74% and T1-MPRAGE 46%, p= 0.005).

Reduced gray-white matter contrast of the motor cortex is more pronounced on DIR compared to T1-MPRAGE on quantitative and qualitative assessments of normal MRI exams. In abnormal cases, reviewers more definitively identified the motor cortex on DIR. In cases with distorted brain anatomy, DIR may be a useful adjunct sequence to localize the motor cortex.
