| central serous retinopathy | Detachment of the sensory retina induced by decreased adhesion between cells of the retinal pigment epithelium which permits plasma from the choriocapillaris to enter subretinal space. Synonym: central angiospastic retinopathy, central serous retinopathy. (05 Mar 2000) |

| retinopathy | 1. <ophthalmology> Retinitis: inflammation of the retina. 2. <disease> Retinosis: degenerative, noninflammatory condition of the retina. Origin: Gr. Pathos = disease (18 Nov 1997) |
| retinopathy of prematurity | <ophthalmology, paediatrics> A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterised by vascular dilatation, proliferation, and tortuosity, oedema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (03 Jul 1999) |
| retinopathy punctata albescens | A disease in which both fundi show numerous white dots through the retina; causes night blindness. (05 Mar 2000) |
| gravidic retinopathy | Sudden angiospasm of retinal arterioles, later followed by retinal vascular signs of advanced hypertensive retinopathy; vascular changes disappear rapidly after termination of the pregnancy. Synonym: eclamptic retinopathy, gravidic retinopathy. (05 Mar 2000) |
| rubella retinopathy | Peripheral pigmentary retinal changes in congenital rubella, not affecting visual function. (05 Mar 2000) |
| circinate retinopathy | A retinal degeneration marked by a girdle of sharply defined white exudates around an edematous macula; usually bilateral and typically affects the aged. (05 Mar 2000) |
| pigmentary retinopathy | <ophthalmology> Disease caused by overactivity of the pigmented retinal epithelial cells, leading to damage and occlusion of photoreceptors and blindness. (18 Nov 1997) |
| compression retinopathy | See: Berlin's oedema. See: traumatic retinopathy. (05 Mar 2000) |
| proliferative retinopathy | <ophthalmology, pathology> A disease of the small blood vessels of the retina of the eye. See: diabetic retinopathy. Origin: Gr. Pathos = disease (09 Oct 1997) |
| Purtscher's retinopathy | Transient traumatic retinal angiopathy due to a sudden rise in venous pressure, as in compression of the body from seat belt injury; ocular fundi show large white patches associated with the retinal veins about the disk or macula, haemorrhages, and retinal oedema; thought to be due to fat embolism from bone marrow. Synonym: Purtscher's disease, transient retinopathy, traumatic retinopathy. (05 Mar 2000) |
| sickle cell retinopathy | A condition marked by dilation and tortuosity of retinal veins, and by microaneurysms and retinal haemorrhages; advanced stages may show neovascularization, vitreous haemorrhage, or retinal detachment. (05 Mar 2000) |
| hypertensive retinopathy | A retinal condition occurring in accelerated vascular hypertension, marked by arteriolar constriction, flame-shaped haemorrhages, cotton-wool patches, star-figure oedema at the macula, and papilledema. (05 Mar 2000) |
| solar retinopathy | A macular burn from excessive exposure to sunlight or other intense light (e.g., the flash of a short circuit); characterised subjectively by reduced visual acuity. See: solar maculopathy. Synonym: electric retinopathy, solar retinopathy. Origin: photo-+ retina, + G. Pathos, suffering (05 Mar 2000) |
| diabetic retinopathy | <ophthalmology, pathology> A major cause of blindness in diabetics. Retinal disease results from adverse effects on the blood vessels which supply the retina. Swollen retinal vessels which leak fluid into the retina are commonly seen on physical examination of the eyes. Poorly controlled insulin dependent diabetes and/or hypertension are the major risk factors. Symptoms include decreased vision and colour perception. Origin: Gr. Pathos = disease (27 Sep 1997) |
