REVIEW
Pipsa Saharinen, Lauri Eklund, Kari Alitalo
The endothelial angiopoietin (ANG)-TIE growth factor receptor pathway regulates vascular permeability and pathological vascular remodelling during inflammation, tumour angiogenesis and metastasis. Drugs that target the ANG-TIE pathway are in clinical development for oncological and ophthalmological applications. The aim is to complement current vascular endothelial growth factor (VEGF)-based anti-angiogenic therapies in cancer, wet age-related macular degeneration and macular oedema. The unique function of the ANG-TIE pathway in vascular stabilization also renders this pathway an attractive target in sepsis, organ transplantation, atherosclerosis and vascular complications of diabetes...

BACKGROUND: The macula is an important part of the human visual system and is responsible for clear and colour vision. Macular oedema happens when fluid and protein deposit on or below the macula of the eye and cause the macula to thicken and swell. Normally, it occurs due to diabetes called diabetic macular oedema. Diabetic macular oedema (DME) is one of the main causes of visual impairment in patients. AIM: The aims of the present study are to detect and localize abnormalities in blood vessels with respect to macula in order to prevent vision loss for the diabetic patients...

PurposeIntraocular vascular endothelial growth factor (VEGF) levels increases with the severity of diabetic retinopathy. Response of diabetic macular oedema (DMO) to ranibizumab is driven by VEGF suppression. We hypothesised that the initial reduction of central macular thickness by ranibizumab should be maximum in severe diabetic retinopathy until the levels of VEGF decreases to the levels observed in eyes with mild retinopathy.MethodsConsecutive patients with centre-involving DMO (central subfield thickness (CSFT)>300 μm) who had three consecutive monthly ranibizumab injections followed by as needed therapy were included...

According to the latest findings, macular oedema due to retinal vein occlusion is best treated safely and effectively with near-term intravitreal anti-VEGF therapy (aflibercept, bevacizumab [off label], ranibizumab). After an initial upload of 3 monthly injections of anti-VEGF, the decision on re-injection should be based on OCT (rather than on visual acuity). After initial monthly injections, the "pro-re-nata" (PRN) and the "treat-and-extend" regimens have been predominantly used in the further course of therapy...
