LASIK or Lasik (laser-assisted in situ keratomileusis) is a type of refractive surgery for correcting myopia, hyperopia, and astigmatism. LASIK is performed by ophthalmologists using a laser.LASIK is similar to other surgical corrective procedures such as photorefractive keratectomy, PRK, (also called ASA, Advanced Surface Ablation) though it provides benefits such as faster patient recovery...
A cataract is a clouding of the lens of the eye.
Factors that may speed up cataract formation are :
Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve (the nerve that carries visual information from the eye to the brain).In many cases, damage to the optic nerve is due to increased pressure in the eye, also known as intraocular pressure. Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that...
At birth a baby's vision is very immature, with an acuity of around 3/60. Visual experience in infancy and childhood has a major influence on the development of the visual pathways, particularly the visual cortex. During the critical periods of visual development visual acuity develops as do other modalities such as contrast sensitivity, colour, pattern and motion perception...
Wet macular degeneration is the result of the formation of new, fragile and leaky blood vessels growing under the retina. The growth of these new blood vessels is called angiogenesis...Read More
Myopia is a condition whereby images come into focus in front of the eye, resulting in a blurred image on the retina. The more severe the nearsightedness, the farther the image is from the retina, which results in more blurry vision in the distance...Read More
Retinal detachment is a separation of the light-sensitive membrane in the back of the eye (the retina) from its supporting layers. The retina is a transparent tissue in the back of the eye. It helps you see the images that...Read More
Retinitis pigmentosa (RP) is a group of genetic eye conditions that leads to incurable blindness. In the progression of symptoms for RP, night blindness generally precedes tunnel vision by years or even decades...Read More
Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty)...Read More
Keratoconus (from Greek: kerato- horn, cornea; and konos cone), is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal...Read More
Read on for some yogic eye exercises to strengthen eyes. They are easy to do and most of them can be performed any time of the day wherever you are.
Most of us do not exercise our eye muscles at all, but yet, we work them all the time, causing them to be under constant strain...
Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye.
Its consequences range from subtle but constant irritation to inflammation of the anterior (front) tissues of the eye.
Dry eyes also are described by the medical term...
Meibomitis is a chronic inflammation of the Meibomian glands. There are twenty Meibomian glands, a form of sebaceous glands along the lower eyelid and about forty along the top lid that produce a sebum also called “meibum”.
Bullous Keratopathy is a pathological condition in which small vesicles or bullae are formed in the cornea due to endothelial dysfunction. It results from the failure of the endothelium to maintain the normal dehydrated state of the cornea.
Vernal Kerato conjunctivitis or Spring Catarrh is a recurrent, bilateral and self-limiting inflammation of the conjunctiva and has a periodic seasonal incidence. It is characterized by burning and itching sensations that is accentuated in a warm and humid atmosphere and is most often seen in the spring and summer months.
Coloboma, simply put, is a hole in one of the structures of the eye such as the iris, retina, choroid or optic disc. A coloboma can affect one or both eyes. If both eyes are involved, it can affect them the same way or differently. There are different types of coloboma, depending on the part of the eye affected:
Optic neuritis is an inflammation that damages the optic nerve, a bundle of nerve fibres that transmit visual information from your eye to your brain. Optic neuritis usually affects one eye. Symptoms might include pain, vision loss in one eye, visual field loss, and loss of colour vision or flashing lights.
Fuchs’ dystrophy is a disease of the cornea and occurs when cells in the corneal layer also called endothelium die off. The cells pump fluid from the cornea to keep it clear. However, when the cells die fluids build up and the cornea get swollen and puffy and vision becomes cloudy and hazy.
Post Lasik Ectasia is similar to Keratoconus where the cornea starts to bulge outward after LASIK eye surgery. Post-LASIK ectasia is caused by removing too much corneal tissue during LASIK surgery leaving the remaining corneal tissue too thin thus weakening the cornea and allowing it to bulge under normal eye pressure.
Pellucid Degeneration is a degenerative corneal condition, sometimes confused with Keratoconus. It is characterized by a clear, bilateral thinning (ectasia) in the inferior and peripheral region of the cornea and in some cases affects only one eye.
Stevens-Johnson syndrome (SJS) is an acute blistering disease of the skin and mucous membranes and can cause severe eye problems. The most common cause of this condition is an adverse allergic drug reaction.
Sub conjunctival haemorrhage is a bright red patch appearing in the white of the eye beneath the conjunctiva or the clear lining. It can occur after sudden or severe sneezing, heavy lifting, straining, vomiting or rubbing one’s eyes vigorously.
YAG capsulotomy is a laser eye treatment that is used to improve vision after cataract surgery. (Also called a secondary cataract) In some patients, typically less than 20 % of patients, total vision can become cloudy again after cataract surgery.
Xanthelasma are yellowish patches on the inside corners of one’s eyelids. The patches are made of cholesterol that is under the skin. Xanthelasma is usually indicative of impending heart disease.
