Yes. The medicines known as eye whiteners for eye irritations work by narrowing the blood vessels of the conjunctiva and reducing blood flow into the conjunctiva. This makes the eyes white for a short time, a cosmetic effect. After four to six hours reactive hyperaemia occurs, i.e. the blood vessels dilate again in order to supply the undernourished conjunctiva with nutrients. The eye becomes red again and needs more drops. See similar questions...

There are many different causes of the conditions collectively referred to as dry eye syndrome, including: See similar questions...

Blepharitis can often cause Dry Eye symptoms due to inflammation of the eye lid margins, which is caused by a bacterial infection (Staphylococci). This condition can compromise the quality of the tear film causing tears to evaporate more quickly. The bacteria produce waste material that can cause a mild toxic reaction leading to chronic red, irritated eyes. Click Blepharitis for treatment. LASIK surgery temporarily disrupts the ocular surface/lacrimal gland unit. See similar questions...

Dry eye is a catch-all term referring to abnormalities of the tear layer which normally coats the surfaces of the eyes, providing clear vision and protecting sensitive surface tissues. Other names for dry eye include dry eye syndrome, chronic dry eye, dry eye disease, and keratoconjunctivitis sicca. Dry eye does not mean your eyes are "dry" - in fact, many people who suffer from dry eye have chronically watery eyes. (Click here for more about dry eye symptoms. See similar questions...

No. Atropine eye drops are used to dilate the pupil during eye exams, and also to treat the conditions amblyopia, esotropia and strabismus. Children with DS seem to have a greater dilation in response to atropine, and the dilation appears to last longer as well. However, there is no evidence that atropine eye drops has any effect on the body beyond the eyes. (North RV, Ophthal Physiol Opt, 7(2): 109-114, 1987) See similar questions...

Some systemically administered medicines can promote the development of dry eye if they are taken as long-term medication. The main ones are betablockers to treat high blood pressure, tricyclic antidepressants, pain killers such as aspirin, antihistamines and oestrogens among others. It is important to ask a doctor's advice in this case. See similar questions...

In PRK, because the laser removes tissue from the surface of the eye, the body will attempt to fill in the defect much like if you had a cut on your hand. Since corneal tissue has different healing properties, the process can normally be regulated with the use of topical steroid drops which patients may be required to use over a one-month period. In LASIK, these drops are only used for a week. These drops will rarely cause any problems. See similar questions...

Dry eye syndrome is a condition caused by loss of water from the tear film. When the tear film loses water the concentration of salts and proteins, relative to the amount of water, increases--the tear film concentration increases. When tear film concentration increases scientists say that its "osmolarity" increases. This increase in tear film osmolarity causes the characteristic irritation and changes on the eye surface known as dry eye syndrome. See similar questions...

Artificial tears have been the mainstay of dry eye treatment. Until recently, these used to be recommended like cigarette brands--doctors would hand out whatever they had in the sample closet, and patients would pick their brand. Patients would find that no matter how long or how frequently they used these drops their eyes would still be dry. Fortunately, Jeffrey Gilbard, MD, working at Harvard Medical School's Schepens Eye Research Institute, has developed an eye drop call TheraTears. See similar questions...

During reading and TV or computer viewing, the rate of eyelids blinking reduces significantly, especially in dryer climates. This causes the tear film to evaporate leading to dryness of the eyes. This may happen in some people, especially more when they are tired, or have spent long hours watching TV or computers. Computer Users tend to blink much less frequently (about 7 times per minute vs. a normal rate of around 22 times/minute). See similar questions...

Advice on expiry of eye drops was originally based on the advice of a Working Party convened by the Department of Health and Social Security in 1972. The BNF recognised that these recommendations pre-dated the use of plastic dropper bottles and improvements to preservative systems. However, it is our understanding that since the Department of Health has not rescinded these recommendations, they still remain in force. See similar questions...

association between the use of chloramphenicol eye drops and aplastic anaemia has been suggested. Case-control studies involving a population of 40 million people found no evidence of an increased risk.1 Another study,2 using a UK general practice database, identified 442 543 patients who received 674 148 prescriptions for chloramphenicol eye drops, 3 individuals experienced serious haematological toxicity.
