What is cornea guttata? The cornea guttata is an ocular condition characterised by the appearance of droplet shaped bulges in this part of the eye. As they affect the corne, which is the main refractive element of the eye that allows clear vision of objects, they can cause vision loss or impaired vision. The cornea guttata is the initial alteration of Fuchs' dystrophy, a corneal disease th

What is corneal cross-linking? Corneal cross-linking, often abbreviated as CXL, is a medical procedure used to treat certain eye conditions, such as keratoconus and corneal ectasia. It involves the application of riboflavin (vitamin B2) eye drops and ultraviolet (UV) light to strengthen the cornea, the transparent front part of the eye.   How does corneal cross-linking work? D

What are corneal diseases? Corneal diseases are a group of serious conditions in which the cornea may become clouded, distorted or scarred and can even lead to blindness. The cornea is the clear layer on your eyeball which allows the passage of light into the eye, and this is largely responsible for focusing your vision. Corneal diseases are treated by ophthalmologists. The mos

What is corneal dystrophy? Corneal dystrophies are a group of over twenty genetic conditions which affect the cornea, the front part of the eye. The cornea is made up of five layers and they must be clear in order for you to see well. Water, nutrients and other matter usually pass through these layers but in the case of corneal dystrophies, one or more of these layers becomes water-logged and a

What is a corneal transplant?

This is one of the most common transplants, in which the cornea of a recently deceased donor is used, whose eyes have been tested to ensure that they are su

What is a corneal ulcer? A corneal ulcer is an open ulcer that is found in the outer layer of the cornea. If the corneal ulcer is not treated, it can lead to the appearance of scars on the cornea, to a considerable loss of vision or even to the loss of the eye.

What is a coronary angiography? A coronary angiogram, also known as coronary angiography, is an examination carried out with an X-ray in which the coronary arteries are visualised, along with the blood vessels that surround the heart, whose function is to transport blood to the heart. To visualise the arteries, a special type of dye called contrast medium is injected and X-ray images are taken

What is a coronary angioplasty? Coronary angioplasty is an endovascular procedure to improve blood flow to the heart by dilating arteries with balloons and stents (metal scaffolds). Over time, fat-laden plaques tend to build up within the blood vessels, narrowing and hardening the arteries. A coronary angioplasty can help improve blood circulation to the heart whenever your arteries are
