Hypoxia and Retinal Neovascularization
2008For over 50 years, retinal hypoxia has been considered to be a major causative factor in the development of retinal neovascularization (NV), a condition associated with blindness and vision loss in a variety of retinopathies. Review of the existing literature and results of new experiments from our laboratory strongly suggest that the oxygen-based ...

Automatic Segmentation of Retinal Layer in OCT Images With Choroidal Neovascularization
IEEE Transactions on Image Processing, 2018Age-related macular degeneration is one of the main causes of blindness. However, the internal structures of retinas are complex and difficult to be recognized due to the occurrence of neovascularization. Traditional surface detection methods may fail in

Retinal Neovascularization After Branch Retinal Arterial Obstruction
American Journal of Ophthalmology, 1987We examined two eyes from two noninsulin-dependent diabetic patients that developed vitreous hemorrhage secondary to retinal neovascularization after branch retinal arterial obstruction. Although there was no ophthalmoscopic evidence of diabetic retinopathy, diabetes mellitus may have predisposed the retinas to a neovascular response, which was ...

Neovascularization Detection on Retinal Images
2017Proliferative Diabetic Retinopathy (PDR) is characterized by the growth of new abnormal, thin blood vessels called neovascularzation that spread along the retinal surface. An automated computer aided diagnosis system needs to identify neovasculars for PDR screening. Retinal images are often noisy and poorly illuminated.

Vascular Casts of Experimental Retinal Neovascularization
American Journal of Ophthalmology, 1981Autotransplantation of skin fibroblasts into the vitreous cavity of the rabbit eye resulted in the formation of fibrous strands that rapidly vascularized. To study this neovascularization, we injected methylmethacrylate monomer via the common carotid artery and made plastic casts between three days and three months after transplantation. Budding of new

Retinal Avascularity and Neovascularization Associated With LAMA1 (laminin1) Mutation in Poretti-Boltshauser Syndrome Poretti-Boltshauser syndrome (PBS) is caused by LAMA1 (laminin1) (OMIM 150320) mutations and manifests with neurologic and ocular ...

Indirect Treatment of Peripheral Retinal Neovascularization
American Journal of Ophthalmology, 1982Indirect (scatter) cryotherapy and photocoagulation treatments successfully obliterated peripheral neovascularization in patients with sickle cell retinopathy and talc retinopathy. Fifteen of 17 neovascular fronds in seven eyes of five patients were obliterated. This type of treatment is analogous to panretinal photocoagulation for diabetic retinopathy.

Antiangiogenesis Effects of Endostatin in Retinal Neovascularization
Journal of Ocular Pharmacology and Therapeutics, 2013Pathological retinal angiogenesis is a major cause of vision loss. Endostatin is a natural antiangiogenesis antitumor protein that is widely used in cancer studies. In this study, we investigated the efficacy and potential mechanisms of endostatin for the prevention of retinal neovascularization both in vitro and in vivo.Human umbilical vein ...

Coordinate Control of Retinal Neovascularization
1982Angiogenesis refers to the development of new blood vessels. Such a development can occur as a response to either normal physiological events or abnormal pathological conditions. Examples of normal angiogenic processes include the vascular development which occurs during embryogenesis (Sabin, 1920; Wagner, 1980) and wound healing (Clark and Clark, 1932;

Neovascularization of the Iris in Rhegmatogenous Retinal Detachment
American Journal of Ophthalmology, 1991To identify conditions associated with neovascularization of the iris in rhegmatogenous retinal detachment, we examined 36 eyes with this disorder seen at our hospital between 1979 and 1990. Clinical courses of disease were divided into the following three groups: (1) neovascularization of the iris without a history of a vitreoretinal operation (four ...
