RETINA & VITREOUS
AGE-RELATED MACULAR DEGENERATION
ARMD is a degenerative disease of the retina that mainly affects the macula, the centre of vision, and is the main cause of blindness in patients over 55 years of age.
Diabetes and its effects on the retina is the most frequent cause of blindness in the active population (20 to 74 years). At the time of diagnosis of Diabetes, up to 20% of patients show signs of Diabetic Retinopathy.
Retinal detachment is an ocular disorder that occurs due to the spontaneous separation of the neurosensory retina (inner layer of the retina) from the pigmentary epithelium (outer layer).
Floaters or “flying flies” (myodesopsia) are small spots (in the form of threads, dots, spider webs) that many people see moving in their visual field, especially when they look at a background with intense contrasts.
It is a partial or total obstruction of the veins of the retina. Therefore, we can classify it as central venous thrombosis when the central vein of the retina is obstructed or branch venous thrombosis, when it affects a branch of this central vein.
The macular epiretinal membrane is a tissue that grows on the surface of the retina in the macular area, which is the fundamental area for vision.
A macular hole is an opening in the macula, which is the central area of the retina. The gel that is inside the eye (vitreous) can lose its volume over time and shrink. This deteriorated gel can exert traction on the macula.
Myopia is an eye disorder that causes long distance objects to appear blurred. It is usually due to an increase in the axial length of the eye (large eyes)
Uveitis is an inflammation of the uvea, which is a membrane that surrounds the inside of the eye, formed by the iris, the ciliary body and the choroid, which together form the middle layer of the eye between the retina and the sclera.
Ocular tumours can appear on the eyelids, in the eye (conjunctiva, choroid or retina) and in the orbit (cavity that houses the eyeball). A retinologist treats tumours located in the choroid or retina.
Retinitis Pigmentosa is a disease of the retina where its outer layers are damaged, which is where the photoreceptors are located: the cones and the rods, which are the nerve cells specialized in perceiving light.
