Anatomy & Physiology
This small central pit in the macula is responsible for the highest acuity vision
What is the fovea?
Which retinal disease presents with retinal thickening, hard exudates, and microaneurysms in patients with diabetes?
Diabetic macular edema (DME) as part of diabetic retinopathy.
Name one proposed advantage of targeting Ang‑2/Tie2 in addition to VEGF in retinal disease
What is improved vascular stability, reduced leakage, potentially longer durability between injections, or reduced inflammation?
The subspecialty physicians who primarily treat DME and wAMD with intravitreal injections are called this.
Who are retina specialists
Vabysmo's HCP tagline
What is "Start first with Vabysmo"?
What is the main cause of fluid accumulation in DME at the microvascular level?
Breakdown of the inner blood-retinal barrier from capillary leakage due to hyperglycemia-induced vascular damage
What disease is characterized by drusen, pigmentary changes in the macula, and progressive central vision loss?
Age-related macular degeneration (AMD).
This signaling pathway, known for roles in development and cell survival, has been implicated in retinal vascular development and neuroprotection
What is the Wnt signaling pathway?
Many DME patients are first identified and referred for retina evaluation by this non-ophthalmic specialist.
Who are endocrinologists / diabetologists or primary care physicians?
Vabysmo's MoA tagline
What is "There's more 2 the story of vascular leakage"?
What is the primary arterial supply to the inner retina?
The central retinal artery.
Diabetic macular edema pathophysiology primarily involves breakdown of which barrier?
The inner blood-retinal barrier (retinal capillary endothelial tight junctions).
Name one biomarker (molecular or imaging) that could help select patients likely to benefit from Ang‑2 targeted therapy.
What is elevated Ang‑2 level in ocular fluid, certain OCT features indicating vascular instability, or inflammatory biomarkers?
Average appointment time for a standard injection visit including imaging, consent, and injection typically ranges from this much time in high-volume clinics.
What is approximately 20–45 minutes per visit (depending on workflows)?
EyleaHD's HCP tag line
What is "Start and stay strong with Eylea HD"?
What structural changes in Bruch’s membrane are associated with age-related macular degeneration?
Thickening, accumulation of lipid-rich debris (drusen), calcification, and decreased permeability
Which imaging modality is most useful to identify capillary nonperfusion and leakage?
Fluorescein angiography (FA)
One translational challenge with intravitreal biologics is the potential for this ocular adverse event, sometimes immune-mediated.
What is intraocular inflammation or sterile endophthalmitis?
Name one tailored commercial tactic that works well in low‑volume clinics to encourage adoption of a longer‑acting retinal therapy.
What is offering bundled launch support (scheduling assistance, hub services, training for nurse injectors), targeted patient identification lists, or shared-services models (e.g., visiting injection clinics or outreach programs)?
Eylea's HD durability claim
What is "93% of EYLEAH HD patients successfully maintained intervals >Q12W through week 48"
What is the pigmented cell layer beneath photoreceptors that phagocytoses shed outer segments?
The retinal pigment epithelium (RPE)
Proliferative diabetic retinopathy leads to neovascularization due to upregulation of which growth factor?
Vascular endothelial growth factor (VEGF)
Aside from complement, this class of molecules (e.g., TNF‑α, IL‑6) contributes to retinal inflammation and increased vascular permeability in DME
What are pro-inflammatory cytokines?
Name the single most impactful clinic operational change that would increase uptake of longer-acting retinal therapies in a high-volume retina center
What is "implementing dedicated injection clinics with optimized scheduling and nurse injectors"
What is "AVONELLE" studying faricimab?
