Evaluation of retinal function improvement in neovascular age-related macular degeneration after intravitreal aflibercept injections with the use of the assessment of retinal sensitivity: The use of the assessment of retinal sensitivity in anti-VEGF treatment – a STROBE-compliant observational study

This study compares 2 methods of macular function evaluation: the microperimetric examination (mean central retinal sensitivity and fixation stability) and the distance best-corrected visual acuity (BCVA) examination, which is the most frequently used method of assessing macular function in patients with newly diagnosed wet age-related macular degeneration (AMD) who have been treated with anti-vascular endothelial growth factor (VEGF) drug (aflibercept). Prospective analysis was conducted on 44 eyes of 44 patients treated with intravitreal injection of anti-VEGF (aflibercept) because of newly diagnosed neovascular AMD. According to the research protocol, all patients had a 6-month follow-up. The response to treatment was monitored functionallybyMP-1 microperimetry, fixation, and distance BCVA assessment after injection. Improvement of retinal sensitivity and BCVA was found under aflibercept treatment. There was statistically significant improvement in retinal sensitivity in the MP-1 study 3 and 6 months from the beginning of anti-VEGF therapy. Moreover, a significant improvement in retinal sensitivity between 3 and 6 months of observation was demonstrated. At the same time, up to 3 months from the beginning of treatment, BCVA improved significantly compared to the baseline value. In the 6th month of the study BCVA remained stable without further significant improvement. Microperimetric examination with medium sensitivity and fixation stability assessment is a very valuable ...

Abstract PURPOSE: To evaluate visual and anatomic outcomes following pars plana vitrectomy and intravitreal or subretinal tissue plasminogen activator for submacular hemorrhage in patients with age-related macular degeneration. METHODS: This was a retrospective study on patients with a minimum follow-up of 12 months undertaken at a tertiary referral center. Data collected include demographic details, visual and optical coherence tomography changes, surgical details, and complications. Surgical results were compared with patients who were age and lesion size matched and treated with anti-vascular endoth...

This study aimed to identify and describe anatomical and functional changes on short (1-3 months) and medium (6-12 months) term after intravitreal injections of bevacizumab (Avastin, Genentech) in patients with choroidal neovascularization (CNV) in the context of exudative form of age-related macular degeneration (AMD). We performed a retrospective, analytical, interventional study, based on a series of cases with exudative form of AMD, which also comprised a prospective component related to the inclusion and treatment of the patients with a very new interventional method for that time (2006) and the follow-up of the effec...

CONCLUSION: Treatment with intravitreal injections of aflibercept in a real life setting resulted in a significant improvement in BCVA at 12 months and in a significant anatomic restoration throughout the 24-month follow-up. PMID: 31802046 [PubMed - in process]

Authors: Li HY, Rong SS, Hong X, Guo R, Yang FZ, Liang YY, Li A, So KF Abstract  Many ocular diseases (such as glaucoma, diabetic retinopathy, age-related macular degeneration, and traumatic eye injuries) can result in the degeneration of retinal cells and the subsequent loss of vision. Some kinds of treatments, such as drugs, stem cell transplantation and surgery are reported to be effective in certain patients. However, no confirmatively effective, convenient and low-price intervention has been available so far. Physical exercise has been reported to exert neuroprotective effects on several neurodegenerative...

CONCLUSIONS: Diet patterns were not significantly associated with incident any or incident early AMD. However, consumption of a Western pattern diet may be a risk factor for development of late AMD. PMID: 31810976 [PubMed - as supplied by publisher]

Authors: Muñoz-Ramón PV, Hernández Martínez P, Muñoz-Negrete FJ Abstract Age-related macular degeneration and especially neovascular age-related macular degeneration is the leading cause of low vision in developed countries. Even though the introduction of anti-VEGF drugs in recent years completely changed the management of this condition, its cost, the need for repeated intravitreal injections, and loss of efficacy in the long term are still issues to deal with. Currently, a new generation of novel therapies under development is attempting to address some of these limitations. So...

In this study, we investigated the anti-inflammatory effects and potential mechanisms of verteporfin. The classic lipopolysaccharide (LPS)-induced inflammation cell model was used. RAW 264.7 cells were pre-treated with verteporfin or vehicle control, followed by LPS stimulation. Verteporfin inhibited IL-6 and TNF-α at mRNA and protein expression levels. This effect was mediated through inhibition of the NF-κB and JAK/STAT pathways. Finally, verteporfin exhibited an anti-inflammation effect by crosslinking of protein such as NF-κB p65, JAK1, JAK2, STAT1, or STAT3 leading to inflammation. Taken together, th...
