The eye has a rich blood supply similar to other highly active parts of the body. The retina which is the photosensitive inner layer of the eyeball responds to light stimuli and generates impulses that travel via the optic nerve to the brain. This accounts for the sense of vision. The central retinal artery supplies blood >> Read More ...
Glaucoma is condition characterized by progressive optic nerve damage and is very often due an increase in intraocular pressure (IOP). It cannot be cured but early detection and treatment can help to prevent vision loss and blindness, primarily by reducing the intraocular pressure (IOP). Medication in the form of eye drops >> Read More ...
Glaucoma refers to a group of eye diseases that damage the optic nerves due to gradually increasing pressure within the eye, the intraocular pressure (IOP). Glaucoma can develop in one or both eyes. Glaucoma is one of the leading causes of blindness, yet many people are unaware that they have this condition since the >> Read More ...
Redness of the eye, or ocular redness, is a common ailment that may be a symptom of some ocular or even non-ocular disorder or can arise acutely with minor irritation or injury of the eye. It is often accompanied by itching. On its own, excessive redness of the eye is not serious particularly if it passes within a short >> Read More ...
The eye is a highly sensitive organ to light, pressure and other sensations like itching and pain. Since it is exposed to the environment and lacks the protection of skin, apart from the eyelids, the eyes are prone to injury and diseases. Its location and closeness to several other highly sensitive structures may also be a >> Read More ...
Cataract surgery involves removal of the cloudy lens and replacing it with an artificial lens. Not all cataract cases require surgery. However, surgery is the only effective treatment option in advanced cataract causing problems with routine activities such as driving, reading, cooking, watching television, and so on. >> Read More ...
The lens of the eye needs to be clear so that light can pass through it uninhibited and cast an image on the back of the eye (retina). Clouding or opacification of the lens of the eye, which is clear under normal circumstances, is known as a cataract. This usually develops over a long time, impairing vision and may >> Read More ...
The path of light through the eye needs to be uninhibited in order to form a clear image on the retina. The light-sensitive receptors then elicit impulses which are sent to the central nervous system for processing. In order to achieve this, the tissues of the eye has several specialized properties to ensure that it is >> Read More ...
The wall of the eyeball has three main layers – the outer fibrous layer (sclera, cornea), middle vascular and muscular layer (choroid, ciliary body and iris) and the inner neurosensory layer (retina). All three layers adhere to each other and both the outer and inner layers are highly dependent on the rich blood >> Read More ...
The eye has two main areas which are filled with different substances. The anterior segment (front) which constitutes about 20% of the area is filled with a clear watery fluid know as the aqueous humor. It lies between the cornea and the front surface of the lens. The posterior segment (back) which accounts for the >> Read More ...
