Retrograde neurotrophic signaling in rat retinal ganglion cells is transmitted via the ERK5 but not the ERK1/2 pathway.

2014

Purpose Neurotrophic deprivation is considered an important event in glaucomatous retinal ganglion cell (RGC) death. However, the mitogen-activated protein kinase (MAPK) pathway transmitting axonal neurotrophic signals in RGC has not been identified. We investigated the involvement of ERK5 and ERK1/2 in retrograde axonal neurotrophic signaling in rats. Methods Adult Sprague-Dawley rats were used. Retinal immunostaining for ERK5 and MEK5 was performed. Levels of total and phosphorylated ERK5 and ERK1/2 were analyzed in retinal lysate by quantitative Western blotting. The effects of age, brain-derived neurotrophic factor (BDNF) stimulation at RGC soma (intravitreal injection) or axon ending (…

Polypoidal choroidal vasculopathy in pachychoroid: combined treatment with photodynamic therapy and aflibercept

2022

Abstract Introduction To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV).Methods Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SSOCT parameters of clinical activity.Results Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 ± 0.25 to 0.2 ± 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseli…

POOLED ESTIMATES OF INCIDENCE OF ENDOPHTHALMITIS AFTER INTRAVITREAL INJECTION OF ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR AGENTS WITH AND WITHOUT TOPI…

2017

Purpose: To assess the effect of topical antibiotic prophylaxis on postoperative endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents.Methods: A systematic literature search was performed from inception to March 2016 using PubMed, Medline, Web of Science, Embase, and the Cochrane Library, to identify articles that reported cases of endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents. We used a pooled analysis to estimate the incidence of cases of endophthalmitis who developed after injections performed with and without topical antibiotic prophylaxis. We used regression analysis to explore the effects of stu…

Intraoperative dexamethasone intravitreal implant in diabetic macular edema patients undergoing phacoemulsification: The CataDex study

2021

Purpose To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. Methods Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). Resul…

Prophylaxis of Pseudophakic Cystoid Macular Edema with Intraoperative Pegaptanib

2011

The purpose of this study was to determine the efficacy of an intraoperative intravitreal pegaptanib injection during phacoemulsification in preventing the development of pseudophakic cystoid macular edema (CME) following cataract surgery.This prospective, controlled pilot study was carried out at the Department of Ophthalmology, Nuevo Hospital Universitario y Politécnico La Fe, Valencia (Spain). Five hundred patients with cataract and healthy retina were included in the study. Patients were assigned in a 1:1 ratio to receive an intraoperative intravitreal pegaptanib injection (n=250) or not (control group, n=250) associated with standardized phacoemulsification surgery and postoperative tr…

Early OCTA Changes of Type 3 Macular Neovascularization Following Brolucizumab Intravitreal Injections

2022

Background and Objectives: Brolucizumab is a novel anti-vascular endothelial growth factor (VEGF), whose efficacy has been shown in the Hawk and Harrier phase 3 clinical studies. The goal of the present case series is to report initial results of brolucizumab intravitreal injections (IVI) on type 3 neovascularization in neovascular age-related macular degeneration (nAMD), evaluated by optical coherence tomography angiography (OCTA). Materials and Methods: This is a bicentric retrospective case series. Patients with newly diagnosed type 3 MNV treated with brolucizumab IVI and at least 6 months follow-up were enrolled. OCTA en face images and B-scans were analyzed for lesions at baseline, 1 m…

DEXAMETHASONE INTRAVITREAL IMPLANT VS RANIBIZUMAB IN THE TREATMENT OF MACULAR EDEMA SECONDARY TO BRACHYTHERAPY FOR CHOROIDAL MELANOMA

2017

PURPOSE To evaluate the efficacy of an intravitreal dexamethasone (Dex) implant 0.7 mg compared with intravitreal ranibizumab (Ra) for the treatment of radiation maculopathy with macular edema secondary to plaque brachytherapy in choroidal melanoma. METHODS Eight patients were treated with intravitreal Ra, and eight patients received the Dex intravitreal implant. Visual acuity and foveal thickness were evaluated using spectral domain optical coherence tomography. RESULTS The mean calculated irradiation to the fovea and mean times from brachytherapy to maculopathy development did not differ significantly between groups. In the Ra group, a mean 7.8 ± 3.9 injections were given and the mean fol…

Switching to intravitreal fluocinolone acetonide implant for refractory diabetic macular edema: 12- and 24-month results

2021

Purpose: To report visual and anatomical outcomes of chronic/refractory diabetic macular edema (DME) treated with intravitreal fluocinolone acetonide implant. Setting: Retrospective, one arm, multicentric study. Method: Between 2013 and 2018, 27 consecutive eyes of 25 patients with chronic/refractory DME were treated with a fluocinolone acetonide intravitreal implant. Best registered visual acuity (BRVA), central retinal thickness (CRT), and Goldmann tonometry intraocular pressure (IOP) were assessed at 12 and 24 months. The need for IOP lowering treatment as well as top-up therapy during the follow-up were also assessed. Results: The duration of DME prior to treatment in our study was 54 ±…

2014

Purpose: To evaluate safety and clinical results of intravitreal antiangiogenic agents for choroidal neovascularization in pediatric patients. Methods: Retrospective, multicenter, interventional case series. A total of 45 eyes of 39 pediatric patients with choroidal neovascularization of various etiologies were treated with intravitreal injection of antiangiogenic agents (1.25 mg per 0.05 mL of bevacizumab or 0.5 mg per 0.05 mL of ranibizumab). Results: There were 24 girls and 15 boys with group median age of 13 years (range, 3–17 years). Mean follow-up period was 12.8 months (range, 3–60 months).
