A 61-year-old patient with bilateral, treatment-naïve, diffuse diabetic macular edema (DME) that had been progressing during the previous 12 months received a single intravitreal injection of aflibercept (Eylea; Regeneron, Tarrytown, NY) to the left eye. At 2-week follow-up, noticeable bilateral improvement of the DME was observed by spectral-domain optical coherence tomography imaging with commensurate improvement of visual acuity to 20/30 bilaterally.

The authors report, for the first time, an association between large colloid drusen (LCD) and choroidal neovascularization in a 58-year-old man. Multimodal imaging confirmed the diagnosis of LCD in both eyes and polypoidal choroidal vasculopathy in the left eye. The patient was treated with monthly intravitreal injections of aflibercept (Eylea; Regeneron, Tarrytown, NY). The authors hypothesize that these deposits are probably associated with retinal pigment epithelium dysfunction and could thus lead to delayed neovascularization and atrophy...

BACKGROUND: We present an interesting case of bilateral retinitis pigmentosa (RP)-associated cystoid macular oedema that responded on two separate occasions to intravitreal injections of aflibercept, despite previously demonstrating only minimal response to intravitreal ranibizumab. This unique case would support a trial of intravitreal aflibercept for the treatment of RP-associated cystoid macular oedema. CASE PRESENTATION: A 38-year-old man from Dubai, United Arab Emirates, presented to the UK with a 3-year history of bilateral RP-associated cystoid macular oedema...

The anti-vascular endothelial growth factor (VEGF) agents such as ranibizumab (Lucentis®) and aflibercept (EyLea®) are currently used as monthly or bimonthly intravitreal injections to treat potentially retinal diseases such as wet age-related macular degeneration (AMD) or diabetic macular edema (DME). Because of the complications associated with repeated intra-vitreal injections, there is considerable interest in developing a sustained delivery system. The purpose of this study was to examine the stability of both therapeutic proteins under physiological conditions as well as when incorporated into drug delivery systems (DDS)...

Diabetic retinopathy (DR) is the leading cause of blindness among working-age adults. DR often leads to diabetic macular edema (DME), which often goes unnoticed until a patient presents with vision loss. However, treatment options and data for DME are continually improving. We know that vascular endothelial growth factor (VEGF) plays a key role in DME progression; therapies that act by inhibiting VEGF production seem to improve visual acuity in patients with DME. Of the anti-VEGF therapies available, two have been approved by the U...

PURPOSE: To assess the 13-month effectiveness and safety of aflibercept in naïve patients with neovascular age-related macular degeneration (nvAMD) in a real-life clinical setting. METHODS: Thirty-two treatment-naïve patients with nvAMD participated in a prospective two-center study. Patients received intravitreal injections of aflibercept (Eylea®), a loading dose of three monthly injections (2 mg/0.05 ml) every 4 weeks for the first 3 months, followed by intravitreal injections every 2 months...

A 60-year-old man diagnosed with macular telangiectasia type 1 (MacTel 1) was treated for 3 years with monthly aflibercept (Eylea; Regeneron, Tarrytown, NY) and serially imaged with spectral-domain optical coherence tomography. When administered monthly, aflibercept appeared to have a beneficial effect on macular edema secondary to MacTel 1. Visual acuity preservation despite minimal chronic macular edema could be attributed to the lack of significant photoreceptor disruption. [Ophthalmic Surg Lasers Imaging Retina...

BACKGROUND AND OBJECTIVE: Prior investigation shows retina specialists may select different treatment for age-related macular degeneration for themselves than for a hypothetical patient. The authors sought to investigate whether a similar bias exists for treatment decisions by retina specialists with regard to diabetic macular edema (DME). PATIENTS AND METHODS: Two surveys asked retina specialists to select treatment for hypothetical patients with DME or for themselves...

Purpose: We determined the intraocular pharmacokinetic properties of intravitreally injected aflibercept (Eylea) in a rabbit model. Methods: Aflibercept was injected intravitreally in 21 eyes from New Zealand White rabbits. The eyes were enucleated 1, 24, 48, 120, 216, 360, and 720 hours (1, 2, 5, 9, 15, and 30 days, respectively) after injection and immediately frozen at -80°C. The concentrations of aflibercept in the vitreous, aqueous humor, and retina/choroid were determined by performing an indirect enzyme-linked immunosorbent assay, and analyzed to understand the pharmacokinetic properties of the drug...

There has been a rapid rise in the use of intravitreal injections, such as anti-vascular endothelial growth factor (anti-VEGF) agents, performed over the past few years for the treatment of ocular neovascular diseases. This study aims to review the systemic and ocular adverse events among patients treated at a tertiary eye center over a period of 8 years. A retrospective review of all intravitreal injections of anti-VEGF performed over an 8-year period at a tertiary eye care center in Singapore was done. We report the frequency of systemic and ocular adverse events and compared it among the various anti-VEGF agents...

A patient with combined diabetic macular edema (DME) and vitreomacular traction (VMT) was treated with a series of intravitreal aflibercept (Eylea; Regeneron, Tarrytown, NY) injections. The VMT progressively released during the course of the five intravitreal injections. This release may have been spontaneous, due to a nonspecific mechanical effect from the injections, or due to a pharmacologic effect from the aflibercept. While treating DME, anti-vascular endothelial growth factor agents may have an additional benefit in releasing VMT...
