Fuch’s corneal dystrophy is a corneal disease that affects the endothelium or the innermost layer of the cornea. It is a non-inflammatory, sporadic or autosomal dominant dystrophy which causes the cornea to swell and the endothelial cells to die. The endothelium layer’s ability to pump water out of the cornea and help maintain corneal transparency is then severely affected, causing glare, halo and reduced visual acuity. This type of dystrophy also progresses rather slowly and can be found in both eyes.
According to research from the American Academy of Ophthalmology, the only risk factor for this condition is an affected parent. This means that anyone who has an affected parent will have at least a 50% chance of passing the gene to their children in an autosomal dominant pattern. However, studies also indicate that certain factors can have an influence on the severity of Fuch’s corneal dystrophy. If there you have a probability of developing this disease, an eye specialist may recommend learning what can cause it to worsen at a more accelerated rate.

Eye floaters look like small specks, dots, circles, lines, strings or cobwebs in your field of vision. They may appear to be floating in front of your eyes, but floaters are actually tiny clumps of gel or cells floating inside the vitreous that fills your eye. Most of them are due to age-related changes that occur as the vitreous thickens, shrinks or becomes more liquid. What you are seeing are the shadows cast by these clumps on your retina, especially when you stare at a bright, plain surface, a reflective object or a blank paper.
While floaters are considered very common and often no cause for concern, there are certain instances that should warrant a visit to a trusted eye clinic in London or elsewhere. Keep an eye out for these medical emergencies to avoid potential damage to your eyesight. Read more from this article: http://bit.ly/2FWQoPt.

While cataracts surgery can safely be performed at any stage of their development, doctors only operate on one eye at a time. This means that in between surgery, your eyes will be out of balance with each other until after the surgery with the second eye. This vision imbalance is referred to as anisometropia, which is derived from the Greek words that literally translate to “the measure of vision is not equal.” In medical terms, it is defined as a condition in which the two eyes have a different refractive power, so there is an equal focus between the two eyes.
Living with anisometropia for weeks or months until your next surgery can be quite difficult. To help you cope with the change, ophthalmologists offer the following tips. Read more from this article: http://bit.ly/2Gu4TPW

The Royal National Institute of Blind People defines secondary glaucoma as a type of glaucoma that occurs as a result of another eye condition, operation, injury or medication. As with primary glaucoma, secondary glaucoma can be open-angle or angle-closure in nature, and it can affect one or both eyes. Since it directly results from an existing condition, however, the causes of secondary glaucoma are easily identifiable and better avoided to some extent. It is therefore vital to be aware of the relationship between glaucoma and the likely conditions that can lead to it with the help of an eye clinic in Harley Street or elsewhere.
Trauma can either be classified as blunt or penetrating, but both types are known to cause secondary glaucoma or more specifically known as traumatic glaucoma. It may not be apparent at the time of injury and may develop over a period of time after the injury. Read more from this article: http://bit.ly/2q03N3f.

LASIK surgery involves reshaping and altering the curvature of the cornea to improve vision, but in doing so, the procedure can also affect the tear film and tear production. It’s not something to be alarmed about, however, as it’s relatively mild and considered as a common side effect of the surgery. In fact, according to experts, as many as eight out of ten LASIK patients experience dry eye symptoms in the following weeks.
Even so, nobody wants to deal with the itchy, stinging feeling of dry eyes, especially while recovering from LASIK. Fortunately, your eye surgeon can help you manage the symptoms to give you relief.
Minimizing Dry Eye Risks
Some people are more susceptible to developing dry eye after LASIK due to different factors. For instance, people with higher degrees of myopia can be at greater risk of dry eye than people with lesser degrees of nearsightedness. The same is true for older people, female patients who have undergone menopause, people with autoimmune diseases and those who are taking allergy, blood pressure, or antidepressant medications.

Recent statistics reveal that over 1.7 million people in England are either blind or partially sighted. This population is expected to quadruple in the next 40 years if nothing is done to treat the various conditions that are fuelling its growth. One of these is corneal dystrophy, a disorder characterised by the development of excess tissues in the cornea. Considered hereditary, the chances of people, whose families have no known history of this disorder, to acquire it is quite slim. But for those who are likely to experience corneal dystrophy, understanding how this disorder works is a top priority when seeking treatment.
What is Corneal Dystrophy?
To better understand this disorder, one must know the functions and vulnerabilities of the cornea, the clear outer layer of the eye. It consists of three sublayers—an outer layer (epithelium), a middle layer made of four more sublayers (Dua’s layer, Bowman’s layer, the stroma, and Descemet’s membrane), and an inner layer (endothelium). Its main functions are to protect the rest of the eye from infectious or irritating substances and to serve as a refractive medium that ensures correct passage of light needed to project images more clearly.

Squint or strabismus is a common condition that usually occurs in young children before they reach preschool age. According to Patient, an online health platform, it affects about 1 in 20 children in the U.K. A squint develops when the child’s eye muscles don’t work together properly in a way that prevents the eyes from looking in the same direction. One eye may look straight ahead, while the other could point inwards, outwards, upwards or downwards.
One costly mistake you can make as a parent is leave squint untreated. Although some children can learn to adapt in due time, strabismus is far from a simple cosmetic issue it appears to be. It can have a significant impact on your child’s health and wellbeing, too. Early correction with help from an eye specialist in London or elsewhere can help children avoid problems caused by squint.
