Summary
Primitive retinal vascular abnormalities, including tumors and telangiectasias, cause vision loss. This review covers their clinical features, diagnosis, and treatments like anti-VEGF therapy.
Area of Science:
- Ophthalmology
- Vascular Biology
Background:
- Primitive retinal vascular abnormalities encompass tumors and telangiectasias.
- These conditions often lead to significant visual impairment due to retinal exudation.
Purpose of the Study:
- To review clinical and diagnostic features of retinal vascular abnormalities.
- To discuss current and emerging treatment options, including anti-VEGF therapy.
Main Methods:
- Literature review of primitive retinal vascular abnormalities.
- Analysis of clinical presentations, diagnostic imaging, and therapeutic outcomes.
Main Results:
- Identified key vascular tumors (e.g., capillary hemangioma) and telangiectasias (e.g., Coats' disease).
- Exudation is a common complication linked to vascular structural defects.
- Intravitreal anti-VEGF therapy shows promise in managing these conditions.
Conclusions:
- Accurate diagnosis of retinal vascular abnormalities is crucial for effective management.
- Treatment strategies are evolving, with anti-VEGF therapy offering new possibilities.

01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
