1. How does a lazy eye happen?
By Lau’Rent Honeycutt

2. What is it
amblyopia - brain focuses on one eye more than the other eye

3. Why it happens?
Eye muscles become weak due to the optical nerve do not transmit to the brain
Eye nerves do not transmit image to brain

4. Causes Genetic Diplopia Congential cataract Congential ptosis
Anisometropic amblyopia
Refractive error

5. Amblyopia
One or both eyes do not develop normal vision during childhood
Anisometropic amblyopia-a chronic blur in 1 eye
Strabismus - the two eyes receive different visual images which causes confusion and diplopia
Accommodative esotropia
Intermittent exotropia

6. Diplopia muscles imbalance to track objects together Double vision
Astigmatism- abnormal curvature of the frontal cornea
Keratoconus – The cornea becomes thin and cone shaped

7. Congenital Cataracts Clouding of the lens of the eye
Proteins in lens breakdown
Interferes with light

8. Congenital ptosis the levalor muscle doesn’t lift eyelid
Causes eyelid to sag

9. Refractive error Refractive error-
Basically neurons in the eye are underdeveloped which cause the brain to focus more on the other eye

10. Cause
Environmental factors
Diabetes
Hypertension

11. Environmental – Diabetes
Catracts
Glacoma- a groups that hurt the eye nerves
retinopathy- affects blood vesseld in retina
Macular edema swelling in the macula( retina)

12. Environmental – Hypertension
hypotension
High blood pressure damages blood vessels to retina’s
Fluid buildup under retina because of a leaky blood vessel
Nerve damage – blocked blood flow to optic nerves

13. Life story Surgery Life in hospital
Eye muscles and nerves not connected
