What are cataracts?
The eyes have a natural lens, which refract light rays on the retina. Retina converts those light rays into signals which are carried through optic nerves to the brain. This is how we are able to see the world.
When a person has cataract, the lens becomes dense and cloudy due to clumping of the protein in the eyes, resulting into a hazy or foggy vision. It is a slow process and does not create problem early on, but eventually it starts interfering with the vision, which makes it difficult to carry on activities like reading, driving(especially during nights), etc.
Cataracts mostly develop due the process of ageing, though injury to the eye may also result in formation of this condition. With age, the proteins in the lens start breaking down, making the lens cloudy, but it may take years till it interferes with the vision.
Some other reasons for developing cataract are-
- Having medical problems like diabetes
- Having any eye injury, eye surgery, or radiation treatments
- Long use of steroids and other medications
- Long exposure to sun and ultraviolet radiations
- Having a family history of cataracts
Sign and symptoms
Common symptoms of cataract include-
- Blurred or hazy vision
- Increased sensitivity to glare and light
- Difficulty with vision at night
- Fading of colours
- Need of brighter light for reading anything
- Seeing halos around the lights
- Increased sensitivity towards light
- Double vision in the affected eye
- Need of frequent changes in the power of glasses or contact lenses
Type of cataracts
Cataracts are classified on the basis of how and where they are formed in the eyes-
- Nuclear cataracts- These are formed in the centre of lens. In this type the lens gradually becomes densely yellow or brown, resulting into blockage of vision.
- Cortical cataracts- They are wedge shaped and are formed on the outer edges of the lens. This type of cataract may extend to the centre of the lens, as the disease progresses.
- Posterior subcapsular cataracts- This type affects the back of the lens. It develops at a higher speed as compared to previous two forms. They cause symptoms like difficulty in reading, seeing glares or halos around the light at night, reducing vision in the bright light, etc.
- Congenital cataracts- This type is present from birth or develop during early childhood. They are less common type, and may be genetic or caused due to intrauterine infection or trauma.
- Secondary cataracts- These are formed as a consequence of some medical conditions like glaucoma and diabetes. Use of steroids and other medications may also lead to cataracts.
- Traumatic cataracts- These may develop as a consequence to any eye injury.
- Radiation cataracts- They develop due to the exposure to radiation, like in cancer treatments.
Factors that may increase the risk of cataract are-
- Older age
- Family history of cataracts
- Previous eye injury
- Excessive exposure to sunlight and uv rays
- Excessive consumption of alcohol
- Prolonged use of corticosteroids
- Exposure to radiation
Doctor will access the symptoms, look into the history and do comprehensive eye test to investigate if cataract is present. The diagnosis of cataract may be established with the help of tests like-
- Visual acuity test- This test is done using an eye chart to asses how well a person can read a series of letters.
- Slit- lamp examination- This instrument allows a doctor to see the internal structure of the eye, hence helps in determining any abnormality present.
- Retinal exam- For retinal examination, doctors put little drops of fluid in the eyes, which helps to dilate pupils. After that it becomes easy to view the back of the eye i.e retina.
If a person consults the best homeopathic doctor in the beginning of the symptoms, when the clouding of lens has just started, homeopathic medicines have been known to revert back the changes in the lens and get them back to their natural state. The medicines act in the most natural ways in restoring the blurred visions.
Homeopathic medicines can prevent the lens from becoming opaque and save further progression of the disease and thus reduce the need of surgeries. Though, to get the best results it is always recommended to see the best homeopathic doctor from the beginning of the disease.
