Keratoconus is a progressive vision disorder which occurs when the normally round cornea becomes thin and cone-shaped, and bulges out, deflecting the light entering the eye leading to a distorted and blurry vision.

Causes of Keratoconus:

Weakening of the collagenous fibre, which holds the cornea in its regular place, leads to its bulging out. Decreased levels of antioxidants in the cornea too cause the condition by damaging the fibre from external pollutants. It is also seen ru...more

It can affect any part of the body, including the arms, legs, hands and even face. The root cause behind excessive melanin production is normally due to hormonal alterations in the body and other health issues. External factors like skin injury, burning, stress, chemical contact and even excessive sun exposure may lead to hyperpigmentation.

A cataract usually forms in the eyes due to clouding of the naturally clear lens. It is mostly age-related.

It is an eye disorder in which the retina is affected by abnormal growth of the blood vessels. Most of the time only one eye is affected. This is not an inherited disease and the principle causes are still unknown. Although in some cases, it has been speculated that some acquired somatic alterations in the NDP gene (Norrie disease (pseudoglioma)) causes Coats disease. The treatment depends upon the symptoms and the intensity of the disease.

There are many symptoms which can be seen in ...more

Our skin gets its colour from melanin. This is a pigment that is produced by a special kind of skin cells. When these cells get impaired then melanin production is also affected. This leads to discolouration of the skin which is called pigmentation. Pigmentation can manifest in many ways. Production of excessive melanin, excessive exposure to the sun, pregnancy and Addison's disease - all these make the skin darker.

On the other hand, too little melanin production leads to the lightenin...more
