This report describes a case of angiographically documented foveal avascular zone (FAZ) enlargement after a single intravitreal injection of bevacizumab for macular edema secondary to central retinal vein occlusion (CRVO). A 71-year-old female was treated with an intravitreal bevacizumab injection for macular edema following CRVO. Despite successfully decreased edema one month after injection, the postinjection best-corrected visual acuity immediately decreased from 20/40 to 20/1000 (Snellen equivalent). The FAZ area increased from 0...

BACKGROUND: The meniscus plays an important role in controlling the complex biomechanics of the knee. Meniscus injury is common in the knee joint. The perimeniscal capillary plexus supplies the outer meniscus, whereas the inner meniscus is composed of avascular tissue. Angiogenesis factors, such as vascular endothelial growth factor (VEGF), have important roles in promoting vascularization of various tissues. VEGF-mediated neovascularization is beneficial to the healing of injured tissues...

The hypoxia inducible factors (HIFs) mediate changes in gene expression in response to hypoxia, and mediate key physiological responses such as angiogenesis. They play important roles in development and normal physiology, as well as in ischaemic and other pathologies. The human eye is a complex organ, with tight regulation of vascularisation and oxygen delivery, with the highly specialised retina containing both highly vascularised and avascular regions. This review, written to honour the significant contribution of Lorenz Poellinger to this field, covers the role of the HIFs in normal development of the eye, specifically the vasculature, as well as their roles in numerous retinal pathologies, including ischaemic retinopathies, and age-related macular degeneration (AMD)...

Transient osteoporosis of the hip (TOH) is a temporary clinical condition of unknown etiology which usually resolves with conservative therapy though may be complicated by fracture or progression to avascular necrosis (AVN). TOH may be slightly more prevalent in men but when it occurs in women, it is most often seen in the latter part of pregnancy. Though fracture is a rare complication of TOH when it occurs, it is most often associated with TOH occurring in pregnancy. Magnetic resonance imaging (MRI) is the best method to diagnosis TOH...

Autophagy is activated during nutritionally depleted or hypoxic conditions to facilitate cell survival. As growth plate is an avascular and hypoxic tissue, autophagy may have a crucial role during chondrogenesis, however the functional role and underlying mechanism of autophagy in regulation of growth plate remains elusive. In this study, we generated (TamCart) Atg7(-/-) (Atg7cKO) mice to explore the role of autophagy during endochondral ossification. Atg7cKO mice exhibited growth retardation associated with reduced chondrocyte proliferation, differentiation and increased chondrocyte apoptosis...

The function of articular cartilage as an avascular tissue is mainly served by collagen type II and proteoglycan molecules. Within this matrix homeostasis between production and breakdown of the matrix is exceptionally sensitive. The current study was conducted to identify regional differences in specific alterations in cartilage composition during the osteoarthritic process of the human knee joint. Therefor the changes in the expression of the key molecules of the extracellular matrix were measured in dependence of the anatomical side (femoral vs tibial) and associated with immunohistochemistry and quantitative measurement...

Although intravitreal injection of anti-vascular endothelial growth factor agents (IVA) can induce rapid regression of retinopathy of prematurity (ROP), late reactivation of the ROP can occur in the form of tractional retinal detachment (TRD) from contracted recurrent extraretinal fibrovascular proliferation. The authors report a case of bilateral TRD for recurrent ROP in a 3-year-old, which is the latest-reported reactivation to date. The authors propose that persistent avascular retina in eyes that have undergone IVA for ROP receive laser ablation to prevent late recurrences...
