AGE RELATED MACULA DEGENERATION (ARMD)
ARMD is an aging change or wearing out of the central retina. It causes loss of central vision. This makes reading and driving difficult. Later, if it gets more severe, it becomes difficult seeing faces, crossing roads, and cooking. The peripheral or side vision always remains, so even if the central vision is poor, it is always possible to see and get round the house and see to the side.
ARMD is usually a progressive condition. Invisible early changes occur, then usually some type of dry ARMD, such as drusen. Later, the dry changes may progress, usually slowly, to cause geographic atrophy and thinning of central retina. These are all termed part of ‘dry’ ARMD. Treatment for geographic atrophy is awaited.
A secondary change may then develop in some people. Blood vessels may start to grow in the centre of the retina in the macula area. The blood vessel growth causes leakage and scarring, and is termed ‘wet’ ARMD. These wet changes can be slowed down with anti-VEGF eye injections.
CENTRAL SEROUS RETINOPATHY
Central serous retinopathy (CSR), also known as central serous chorioretinopathy (CSC), is an eye condition which causes visual distortion, due to accumulation of fluid underneath the retina.To confirm the diagnosis of central serous retinopathy, a dilated examination of the retina followed by optical coherence tomography and fluorescein angiography is performed.The angiography test usually shows one … Continue reading CENTRAL SEROUS RETINOPATHYRead More
Retinal vein occlusion is a common vascular disorder of the retina. Obstruction of the retinal vein at the optic nerve is referred to as central retinal vein occlusion (CRVO) and obstruction at a branch of the retinal vein is referred to as a branch retinal vein occlusion (BRVO). Branch Retinal Vein Occlusion The symptoms of … Continue reading VEIN OCCLUSIONRead More
A Retinal detachment is a disorder of the eye in which the retina peels away form its underlying layer of support tissue. Initial detachments may be localized, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. It is a medical emergency. The retina is a thin layer of light-sensitive … Continue reading RETINAL DETACHMENTRead More
