Early Detection Of Eye Diseases

  1. 2. <ul><li>There are some eye diseases which don’t cause any problems to the patient but bring about permanent and irreversible damage to the vision </li></ul><ul><li>These are called the ‘silent thieves’ of eyesight </li></ul><ul><li>When caught early, a lot of damage can be prevented </li></ul>
  2. 3. <ul><li>Most of them occur above 40 yrs age </li></ul><ul><li>Some of them are.. </li></ul><ul><li>Glaucoma </li></ul><ul><li>Macular degeneration </li></ul><ul><li>Diabetic retinopathy </li></ul><ul><li>Cataract </li></ul>
  3. 4. <ul><li>Some of them occur in young age </li></ul><ul><li>Lazy eye/amblyopia/squint </li></ul><ul><li>Retinal holes /detachment in myopes </li></ul>
  4. 6. <ul><li>Also commonly known as ‘black water’ in which optic nerve of the eye gets damaged resulting in permanent vision damage </li></ul><ul><li>In this condition the vision starts reducing from the side, therefore the patient does not realize the defect till it’s too late </li></ul>
  5. 10. <ul><li>Detection is very simple </li></ul><ul><li>Eye Pressure must be checked regularly after the age of 40 </li></ul><ul><li>Eye pressure should be checked by an Ophthalmologist when one goes for a routine eye check up/glass check up. </li></ul>
  6. 11. <ul><li>If the eye pressure is raised, eye drops are started to control the pressure </li></ul><ul><li>Occasionally surgery may be required if eye pressure is very high </li></ul>
  7. 12. <ul><li>But whatever vision damage has already occurred due to glaucoma cannot be reversed </li></ul><ul><li>Therefore it is important to detect glaucoma at the earliest </li></ul><ul><li>A person may not have any complaints like pain or discomfort and still may have Glaucoma </li></ul>
  8. 15. <ul><li>The incidence of Glaucoma in general healthy population above 40 yrs of age is about 1 to 2 per 100 individuals </li></ul><ul><li>Risk of glaucoma becomes higher in diabetics and blood pressure patients </li></ul>
  9. 16. <ul><li>Is the damage to retina because of diabetes. Retina is like a film of the camera </li></ul>
  10. 17. 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
  11. 18. <ul><li>If Centre is involved the patient </li></ul><ul><li>Appreciates the problem early </li></ul>
  12. 19. <ul><li>But if problem starts from the side, it does not affect vision early and patient may not realize the presence of diabetic retinopathy </li></ul>
  13. 20. <ul><li>Damage is because Diabetes damages the blood vessels causing bleeding to occur in the retina </li></ul>
  14. 21. <ul><li>Every diabetic is at risk </li></ul><ul><li>80% of diabetics have retinopathy at some stage of life, irrespective of control of diabetes </li></ul><ul><li>Of these 20% have serious retinopathy causing permanent visual problems </li></ul>
  15. 22. <ul><li>Persons are at more risk if they also have associated </li></ul><ul><li>Poor sugar control </li></ul><ul><li>Blood pressure </li></ul><ul><li>Kidney problem </li></ul><ul><li>Cholesterol problem </li></ul>
  16. 23. <ul><li>Retina is checked by an ophthalmologist by putting dilating drops </li></ul><ul><li>Frequency and interval of check up depends upon extent of problem </li></ul>
  17. 24. <ul><li>Treatment is in the form of lasers ( special light) </li></ul><ul><li>Sometimes injections and surgery may also be required </li></ul>
  18. 29. <ul><li>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 </li></ul><ul><li>Early detection and treatment with laser is the method of choice </li></ul><ul><li>Treatment with Retinal Lasers is In-expensive if treated early </li></ul>
  19. 30. <ul><li>Macula is the centre most sensitive point of the retina responsible for vision </li></ul><ul><li>It can often be damaged due to aging </li></ul>
  20. 31. <ul><li>In this condition, abnormal blood vessels can grow into the macula quietly causing vision damage </li></ul>
  21. 32. <ul><li>In initial stages it may go unrecognized by the patient since it affects one eye in the beginning. </li></ul><ul><li>The patient compensates vision with other eye and does not realize the visual loss until its too late </li></ul>
  22. 33. <ul><li>Until recently, there was no treatment available and the elderly used to go blind with this condition </li></ul><ul><li>Recently, there are Injections and lasers available to treat these conditions if treated early. </li></ul><ul><li>There is no treatment if the condition is detected late </li></ul>
  23. 34. <ul><li>Is the clouding of normal lens of the eye </li></ul>
  24. 36. <ul><li>Provide a sharper Image contrast </li></ul>
  25. 39. <ul><li>Age criteria –above 18 years of age </li></ul><ul><li>Aim is to have permanent independence from glasses </li></ul><ul><li>Risk is less than that with wearing contact lenses for life time </li></ul>
  26. 40. <ul><li>All of us have heard about the old saying </li></ul><ul><li>A stitch in time saves nine </li></ul><ul><li>In the same way, early detection of eye </li></ul><ul><li>diseases and their timely management </li></ul><ul><li>can prevent significant vision loss </li></ul>
  27. 41. <ul><li>THANK YOU </li></ul>
