Blurred Vision

Blurred Vision

1. Anatomy of the eye

   • The orbit
     • Formed by seven bones
   • The eye ball

2. Physiology

   • Physiology of Vision
   • Physiology of Color Vision
     • Color Blindness
       • Lack of a particular color receptive cone type.
         • Protanopia
           • Loss of Red cones
         • Deuteranopia
           • Loss of Green cones
         • Blue Weakness
           • Rare
       • Ishihara Chart
         • Rapid method to for determining color blindness based on spot chart.
     • 3 Types of Cones
       • Blue cone - (s-Type)
       • Red cone - ( L-Type)
       • Green cone (M-Type)

3. Intraocular Pressure

   • Intraocular pressure (IOP) is the fluid pressure inside the eye.
     • Measuring it
       • How?
         • Tonometry
       • Why?
         • IOP is an important aspect in the evaluation of patients at risk of glaucoma.
       • In what unit?
         • mmhg
       • Normal Range?
         • 12-22 mm Hg

4. Common Eye Defects

   • Cataract

5. Glaucoma

   • Defintion
     • Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye.
   • Epidemiology
     • In the UK: 2 out in 100 people over the age of 40
   • Risk Factors
     • Age
     • Race
     • Family History
     • Medical conditions( Diabetes-Hypertension)
     • Physical injuries of the eye
     • Eye anatomy
     • Corticosteroid use
   • Types
   • Pathogenesis
   • Treatment

6. Examination

   • Eye Examination
   • Visual Acuity

7. Aqueous humor

   • Physiology of Aqueous humor
   • Function ?
     • Support the wall of the eyeball
     • Nourishes the cornea & the lens
     • Removes the products of metabolism form the cornea & the lens
   • Definition
     • Is a clear fluid that fills the anterior & posterior chambers of the eyeball.
