There are some eye diseases which don’t cause any problems to the patient but bring about permanent and irreversible damage to the vision
These are called the ‘silent thieves’ of eyesight
When caught early, a lot of damage can be prevented
![Page 3: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/3.jpg)
Most of them occur above 40 yrs ageSome of them are..
Glaucoma Macular degeneration Diabetic retinopathy Cataract

Some of them occur in young age
Lazy eye/amblyopia/squint Retinal holes /detachment in myopes

Also commonly known as ‘black water’ in which optic nerve of the eye gets damaged resulting in permanent vision damage
In this condition the vision starts reducing from the side, therefore the patient does not realize the defect till it’s too late

• Detection is very simple• Eye Pressure must be checked regularly
after the age of 40
• Eye pressure should be checked by an Ophthalmologist when one goes for a routine eye check up/glass check up.
![Page 11: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/11.jpg)
If the eye pressure is raised, eye drops are started to control the pressure
Occasionally surgery may be required if eye pressure is very high
![Page 12: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/12.jpg)
• But whatever vision damage has already occurred due to glaucoma cannot be reversed
• Therefore it is important to detect glaucoma at the earliest
• A person may not have any complaints like pain or discomfort and still may have Glaucoma
![Page 13: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/13.jpg)
![Page 14: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/14.jpg)
![Page 15: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/15.jpg)
The incidence of Glaucoma in general healthy population above 40 yrs of age is about 1 to 2 per 100 individuals
Risk of glaucoma becomes higher in diabetics and blood pressure patients
![Page 16: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/16.jpg)
Is the damage to retina because of diabetes. Retina is like a film of the camera
![Page 17: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/17.jpg)
Once damaged it cannot be repaired
Depending upon whether the centre or peripheral part of the film gets affected, patient realizes damage in vision early or late respectively
![Page 18: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/18.jpg)
If Centre is involved the patient Appreciates the problem early
![Page 19: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/19.jpg)
But if problem starts from the side, it does not affect vision early and patient may not realize the presence of diabetic retinopathy
![Page 20: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/20.jpg)
Damage is because Diabetes damages the blood vessels causing bleeding to occur in the retina
![Page 21: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/21.jpg)
Every diabetic is at risk 80% of diabetics have retinopathy at
some stage of life, irrespective of control of diabetes
Of these 20% have serious retinopathy causing permanent visual problems
![Page 22: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/22.jpg)
Persons are at more risk if they also have associated
Poor sugar control Blood pressure Kidney problem Cholesterol problem
![Page 23: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/23.jpg)
Retina is checked by an ophthalmologist by putting dilating drops
Frequency and interval of check up depends upon extent of problem
![Page 24: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/24.jpg)
Treatment is in the form of lasers ( special light)
Sometimes injections and surgery may also be required
![Page 25: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/25.jpg)

• It is a false notion that surgery can correct the damage completely; in fact once the eye has reached the surgery stage , only little can be done to restore the vision
• Early detection and treatment with laser is the method of choice
• Treatment with Retinal Lasers is In-expensive if treated early
![Page 30: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/30.jpg)
Macula is the centre most sensitive point of the retina responsible for vision
It can often be damaged due to aging
![Page 31: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/31.jpg)
In this condition, abnormal blood vessels can grow into the macula quietly causing vision damage
![Page 32: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/32.jpg)
In initial stages it may go unrecognized by the patient since it affects one eye in the beginning.
The patient compensates vision with other eye and does not realize the visual loss until its too late
![Page 33: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/33.jpg)
• Until recently, there was no treatment available and the elderly used to go blind with this condition
• Recently, there are Injections and lasers available to treat these conditions if treated early.
• There is no treatment if the condition is detected late
![Page 34: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/34.jpg)
Is the clouding of normal lens of the eye

Provide a sharper Image contrast

Age criteria –above 18 years of age
Aim is to have permanent independence from glasses
Risk is less than that with wearing contact lenses for life time
![Page 40: Early Detection Of Eye Diseases](https://reader034.fdocuments.in/reader034/viewer/2022042502/559c26c11a28ab13358b45c7/html5/thumbnails/40.jpg)
All of us have heard about the old saying
A stitch in time saves nine
In the same way, early detection of eye diseases and their timely management can prevent significant vision loss
