Retinopathy

Rieger outlined center known as retinitis, youth hemorrhagic macular disease. The disease occurred in and around the macula of the arc up the exudative chorioretinal lesions, accompanied by subretinal neovascularization and bleeding. Clinically it is not uncommon to see, the general incidence of monocular, aged more than 50 years old. Cause pathogenesis is unknown. The present view is macular subretinal neovascularization in a long-due, it comes from choroidal. Pathological changes of granulomatous inflammation. Clinical manifestations centers lost their sight, the dark centers, visual deformation. Vitreous no inflammatory changes. Fundus of the macular yellow, gray exudative lesions and bleeding, round or oval, obscure, slightly protruding. size is about 1 / 4 - 3 / 2 optic disc diameter (PD). To a PD for the following styles. Lesion edge of a circular arc or bleeding, sometimes showed radiation-shaped with a bleeding point. Peripheral lesions with a pigment disorder zone. Most lesions in the central Au center, a radius of the PD range. The end of the course, macular yellow-white scar formation. Fundus examination fluorescence angiography, in the early arterial or arterial phase, which is equivalent to exudative lesions Department granular, Lace-like many other forms of neovascular network. Fluorescent overhead hemorrhage, bleeding on the geopolitical zone have hinted fluorescence. Neovascularization late fluorescein leakage forming strong fluorescence District. Treatment of drug therapy, laser photocoagulation is the treatment of choroidal neovascularization in an effective manner. In the active phase, macular lesion located in a center / outside 4PD, viable laser treatment.
