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
