Making ophthalmology easy with descriptions relating to the most well known eye afflictions

Ophthalmology is a lot more than a specialist topic, just because people are very naive about the best practices for ensuring their eyes stay healthy and how to spot when they have a potentially fatal eye affliction. The main reason for this is because a lot of people are extremely sensitive about their eyes and even dislike the idea of touching them when inserting contact lenses. So to give you a bit of information relating to ophthalmology the team at eysite.org have written an informative article to help you identify how your eyes function and any potential eye diseases to look out for:

Lasik eye surgery is a variety of refractive surgery that helps to fix hyeropia, astigmatism and myopia. That means this surgery is an useful alternative to wearing glasses or corrective lenses, which most people dislike wearing. In some ways the procedure is quite like other surgical corrective options like photo-refractive keratectomy and refractive surgery and is therefore a common solution to bad eye sight. As a procedure, it involves surgical remodelling of the cornea, specifically reshaping its curvature. There is the possibility that the eye will reject the surgery and revert back to its original state, however any other side effects will be at a minimum.

The type of technology being used by an ophthalmologist will change depending on the specific condition being treated. For an invasive cornea surgical operation a Ziemer LDV Femtosecond precision laser is used. This equipment allows the surgeon to operate on the eye without having to use a blade. There is an OCT (Ocular Coherence Tomographer), which is a new form of non-invasive imaging technology for mapping the shape, size and contours of an eye. Lastly, there are procedures along the lines of Anti-VEGF drugs and Fluorescein angiography for more specialist ailments. These are just a few examples of the equipment and procedures that are currently in use by qualified ophthalmologists.

Macular degeneration is a painless condition which leads to a gradual loss of vision in the macula (the centre of the visual field) due to damage to the retina. As it progresses, macular degeneration usually makes it difficult to recognise faces, however peripheral vision usually remains intact. It takes two forms, dry (nonexudative) and wet (exudative). The former is caused when cells thin and degenerate in the macula, while the latter is seen as more serious and is caused when blood vessels grow abnormally in the choriocapillaris behind the retina. As the progression of macular degeneration can be slowed by taking vitamin supplements with high doses of antioxidants surgery of eye is never the first option for someone who suffers from macular degeneration.

Even though you may believe that cataracts only affects older people, younger people can be affected by the condition too. They are better known as congenital cataracts and they develop just before or just after birth. The main feature of the condition includes the clouding of the eye, which can range from milder cases to entire opacity. Near-sightedness (myopia) is one clear symptom as well as the gradual yellowing of the lens and a lack of perception of the colour blue. Treatment involves a cataract operation or cataract surgery. If treatment is not provided loss of vision and even blindness can result. In the elderly the condition leads to shrinkage of the lens and swelling.

Corneal transplantation or grafting occurs when a cornea becomes damaged and is replaced by donated corneal tissue. For instance, if a person develops fuchs dystrophy (a degenerative corneal disease which affects both of the eyes) or Keratoconus (a disorder which changes the shape of the cornea and causes substantial distortion of vision) then a cornea transplant is normally needed. This is where healthy donated corneal tissue is grafted onto the damaged/diseased cornea to restore the damage caused by the disease - the graft coming from the cornea of a deceased donor. cornea transplants or keratoconus surgery are often categorised as the most severe treatment options for cornea disease - this is because in most cases conditions can be treated by simply wearing corrective lenses.

In the UK, higher educational courses can offer postgraduate degrees in ophthalmology. Good examples of the educational institutions include The Royal College of Ophthalmologists, the Royal College of Glasgow and, the Royal College of Edinburgh. An ophthalmologist must have one of these qualifications if they want to work in the UK. When the postgraduate has passed their course, the majority of the students tend to get placements at the NHS to advance their knowledge and improve their practical skills. As a matter of fact, a large number of laser eye specialists provide training programs to help people become entirely qualified ophthalmologists. However, most of the time these are vocational courses which can only be taken after a postgraduate qualification.

After reviewing the above descriptions you should have now have a deeper understanding of the health of your eyes and how to spot a serious condition.
