  1. THE EYE

  2. Anatomy of the Eye

  3. Common Disease of the EyeCorneal Laceration • James is a 22 yrs old martial arts athlete who sustained a kick to his right eye 6 months ago. • He sustained injury to his right cornea laceration due to the contact lens • He was seen by an opthalmologist and treated for several weeks • But he still has blurred vision in his right eye • It is best seen under slit lamp, after flourescin staining

  4. Corneal Laceration The corneal injury is visualised as a white patch on the cornea

  5. Flourescin Staining Flourescin staining selectively stains damaged corneal tissue

  6. Further Treatment • In full thickness corneal laceration, aqueous humour may leak out resulting in distortion of the shape of the eyeball. • He wanted to continue fighting, so further treatment with Phototherapeutic keratectomy (PTK) or Corneal Transplant. • Failure to do so, he may not be able to clear his Pre-participation examination with 'one good eye'.

  7. Cataracts • Cataracts - clouding or opacification of the natural lens of the eye • Cataract Vision

  8. How can cataracts be treated? • The only treatment for cataracts is surgical removal. • Cataract surgery is the removal of the eye lens and replacing it with an artificial one. • Two basic types of surgical procedures to treat cataracts • (1) Phacoemulsification - utilizes a small incision on the side of the cornea to access the cataract with a tiny probe. Ultrasound is then used to break up the lens for removal by suction. This is the most popular kind of cataract surgery. • (2) Extracapsular surgery -This procedure requires a longer incision. The cloudy core is removed intact followed by removal of the remaining lens by suction. • If the eye is otherwise healthy, an intraocular lens may be used to replace the natural, cloudy lens. This lens requires no care. • Post-operative orders carefully. Not to bend over or lift heavy objects for a few days or weeks. A protective eye shield will reduce the chances of injury to the eye.

  9. Professor Fred Hollow’s work to restore sight to the cataract blind in developing countries was ongoing 15 years after his death.Cataracts are the cause of about half of all cases of avoidable blindness in developing countries and they can be removed with a relatively simple operation costing as little as $25.

  10. Retinal Detachment • Can be caused by trauma – e.g. boxing • Sudden acceleration and deceleration – bungee jumping, car accidents

  11. Detached Retina

  12. Avulsed Eye ball • Will it ever work again? • What will need to be intact for it to work?
