Macular edema; Other names: Macular oedema, [1] familial macular edema: A 61-year-old man with medical history of type 2 diabetes that presents a macular edema, evidenced by an OCT (the edema marked with arrows). The central image is a 3D reconstruction of the retinal thickness (the edema is coloured in red). Specialty: Ophthalmology
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.

Visual acuity ranges from 20/20 to 20/400. The prognosis is excellent except in case of complications of choroidal rupture, hemorrhage or pigment epithelial damage, but damage to the macula will result in poorer recovery. The outcome can be worsened in the case of retinal detachment, atrophy or hyperplasia. Visual field defects can occur.
At the low end of the range is the absolute threshold of vision for a steady light across a wide field of view, about 10 −6 cd/m 2 (0.000001 candela per square meter). [23] [24] The upper end of the range is given in terms of normal visual performance as 10 8 cd/m 2 (100,000,000 or one hundred million candelas per square meter). [25]
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
The macula (/ˈmakjʊlə/) [1] or macula lutea is an oval-shaped pigmented area in the center of the retina of the human eye and in other animals. The macula in humans has a diameter of around 5.5 mm (0.22 in) and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.
Age-Related Macular Degeneration is a degenerative maculopathy associated with progressive sight loss. It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or ...
