The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber
(the fluid-filled inside of the eye).

The retina is a thin, delicate layer of nerve tissue that lines the inside of the eye. It plays a crucial role in vision by detecting light and converting it into electrical signals, which are sent to the brain through the optic nerve. The brain then interprets these signals as images.
The retina contains two specialised types of cells:
• Rods – responsible for night vision and peripheral (side) vision
• Cones – responsible for colour vision and sharp central vision
Damage or disease affecting the retina can lead to significant visual impairment and, if untreated, may result in permanent blindness. Common retinal conditions include diabetic retinopathy, retinal detachment, macular degeneration, and retinal vascular disorders. Early diagnosis and expert care are essential to protect vision.
Retinal diseases are a group of disorders that affect the retina’s ability to sense light and transmit visual signals. These conditions may develop gradually or suddenly and can significantly reduce vision.
Many retinal diseases progress silently, producing few or no symptoms until advanced stages. Regular eye examinations using modern retinal imaging technology are therefore vital for early detection and timely treatment.
Some of the most frequently encountered retinal conditions include:
Damage to retinal blood vessels caused by long-standing diabetes
Fluid accumulation in the macula leading to vision loss
Degeneration of the central retina in older adults
Separation of the retina from the eye wall, a medical emergency
Blockage of retinal veins causing swelling and bleeding
A small break in the macula affecting central vision
Scar tissue formation on the retinal surface
Genetic conditions such as retinitis pigmentosa
Retinal disorders are a growing cause of visual impairment in India, largely due to the increasing prevalence of diabetes and longer life expectancy.
Early detection through routine eye examinations can significantly reduce the risk of vision loss.
Some key causes behind Retinal Diseases are:
Diabetes is a common disease in which the body produces too much glucose (sugar) over a long period of time. This can cause damage to the very small blood vessels in the back of the eye (retina), leading to a disease called Diabetic Retinopathy and a disease called Macular Oedema.
Ageing is a natural process that occurs as we age and causes deterioration of the retina. This puts people over the age of 60 at a higher risk for developing a disease called Age-Related Macular Degeneration (AMD), which can also cause blindness.
High Blood Pressure (Hypertension) can affect how the blood flows through the retina and can cause the arteries in the retina (and also the arteries in the body) to get smaller, leak, or become blocked, which will cause a decrease in vision.
Eye Injury/Traumatic Eye Injuries (blunt trauma or penetrating trauma) to the eyeball can cause tearing of the retina, bleeding, or retinal detachment. Dr Krishnendu Nandi, the best retina doctor in Kolkata, can provide the best suggestions regarding this disease.
Genetic Factor(s) which means people can inherit conditions like Retinitis Pigmentosa, which is a disease caused by genetic abnormalities affecting how the cells in the Retina function.
High Myopia (Severe Nearsightedness) is a condition where the Eyeball gets longer, elongating the Retina and making it more susceptible to thinning, tearing, and retinal detachment.
Smoking is also a leading cause. There are studies that indicate that smoking greatly increases the likelihood of developing AMD and increases oxidative stress in the eye.
Systemic Disorders are also a huge contributing factor. Poor diet and lifestyle choices, such as obesity, lack of physical activity, etc., contribute to the development of systemic disorders, which have an indirect effect on the health of the retina.
Autoimmune Disorders/Inflammation are a huge contributory factor. Inflammatory and autoimmune disorders can lead to damage to retinal layers and blood vessels inside the eye.
Certain Medications and Infections are also responsible. Long-term use of specific medications or untreated infections could have a toxic/inflammatory effect on the retina.

Blurred or distorted vision:- For example, lines do not appear as straight, and visualising small details may be difficult. This means you need to see Dr Krishnendu Nandi, the best retina doctor in Kolkata.
Sudden appearance of floaters:- from time to time. When you see small dark blobs or cobwebs appear in your field of vision, this can indicate bleeding or tearing of the retina.
Flashes of light:-that last a very short time and are not accompanied by pain. This usually indicates some traction being placed on the retina or that you might be developing a retinal detachment.
Central vision may have been lost:- If you are having difficulty reading, identifying faces, or getting close enough to objects to see them, then macular involvement may be present.
Vision may become very dark with empty spots:- Some patients will develop blind spots that may progress if not treated early.
Sudden, painless vision loss:- that is not painful is usually treated as a medical emergency and is usually related to some type of retinal detachment or an ocular vascular blockage.
Poor night vision:- which is possibly caused by damage to cells in the retina that are responsible for your low-light vision.
Changes in colour perception:- include some loss of the brightness and vividness of colours as a result of macular or retinal disease.
Consulting Dr Krishnendu Nandi, the best retina doctor in Kolkata, as soon as any of these symptoms are noticed, will ensure that you can get diagnosed quickly so that you can access the Best Retina Treatment in Kolkata and preserve your vision and overall eye health.
Diabetes or poor blood sugar control:- People with uncontrolled blood glucose have an increased chance of developing damage to their retinas, and therefore, should have regular screenings performed by Dr Krishnendu Nandi, the best retina doctor in Kolkata.
Age above 50 years:-
The chances of developing retinal disorders, specifically age-related macular degeneration, increase progressively after the age of 50 years.
High Blood Pressure: Uncontrolled high blood pressure is harmful to the blood vessels in the retina and aggravates the progression of pre-existing retinal diseases.
High Cholesterol:- The presence of high levels of cholesterol in the bloodstream leads to fatty deposits that impede blood circulation to the retina and cause the formation of blockages within the retina’s blood vessels.
Severe Nearsightedness: People who suffer from severe nearsightedness (high myopia) are at greater risk of developing tears and detachment of the retina because of the way the retina has stretched during the course of the condition.
Tobacco Use: Tobacco use increases the speed at which the retina degenerates, thus posing an increased risk of developing serious eye diseases related to degeneration.
Family History: Individuals with a family history of retinal disorders will also be at a higher risk of developing retinal disorders due to genetic predisposition.
Prior Eye Injury or Surgery: Patients who have sustained an eye injury or who have had prior eye surgery will develop weakening of the retina over time.
For more information regarding the risk factors of retinal diseases, come in touch with Dr Krishnendu Nandi, the best retina doctor in Kolkata.
Advanced intravitreal injections (anti-VEGF drugs and steroids) help reduce swelling, control abnormal blood vessel growth, and stabilise vision in conditions such as diabetic retinopathy, macular degeneration, and retinal vein occlusion.

Vitrectomy is a specialised surgical procedure used to treat advanced retinal conditions such as retinal detachment, vitreous haemorrhage, macular holes, and severe diabetic eye disease. Modern minimally invasive techniques allow faster recovery and better visual outcomes.

While not all retinal diseases can be prevented, the risk of vision loss can be significantly reduced by:
• Regular comprehensive eye examinations
• Strict control of diabetes, blood pressure, and cholesterol
• Maintaining a healthy lifestyle
• Avoiding smoking
• Protecting eyes from injury
Early diagnosis remains the most effective strategy for preserving vision.
