Diabetic Macular Oedema (DMO) is associated with diabetic retinopathy and may be appeared in any stage of the disease. This condition is one of the main macular diseases, among the age-related macular degeneration (AMD), central retinal vein occlusion (CRVO) and vitreomacular traction (VMT). According to the Greek vitreoretinal company, more than 50.000 people are affected by a macular disease. In particular, 30% of diabetic patients, who have diabetes over 20 years will be affected by DMO. Unless the oedema does not be treated with drugs, these patients will soon have a vision decrease.
Macula lutea is a circular area oriented in the central retina. Retina is the inner, neural tissue of the eye, where the light is transformed in electrical signal and is transmitted through the optic nerve to the brain. Macula is responsible for central vision and recognition of faces and color vision. Any disorder on this area causes central vision damage.
Cystoid macular oedema (CMO) occurs secondary after an ophthalmic disorder, trauma or rarely after an eye operation. There is a fluid which accumulates through the retinal layers, causing blurry vision and paramorphopsia of the central visual field. CMO rarely causes permanent vision loss.
Macula is the small area at the center of the retina, which consists of a thin tissue that lines at the posterior chamber of the eye. The macula is the most sensitive part of the retina. Macula helps us read and do detailed visual tasks.
