Ojo Vago = Amblyopia Juan G. Santiago, MD NatalioIzquierdo, MD University of Puerto Rico Dept of Ophthalmology
Introduction • Definition • Causes • Treatment • Consequences • Co-management
Definition • (Amblys = dull) • (Ops = eye) • 2 line difference • Snellen Chart • Prefers one eye?
Background • Good vision is our Mission • Prevalence 2% • VA < 20/80 in 50% • Prevention is important! • Help us win the war!
Visual Prognosis is worst when: • The younger the patient is when amblyopia is diagnosed • The older the patient is when treatment is started
Risk Factors • Premature babies • Neuro Dev Delays • Family Hx • Smoking • Alcohol
Causes • Optic pathway development (10 years) • Associated to Abnormal Visual Input
Strabismic Amblyopia • Esotropia • Inward deviation
Strabismic Amblyopia • Exotropia • Outward deviation
Media Opacity & Amblyopia • Most amblyogenic • Deprivation • Cataract • Aphakia
Media Opacity & Amblyopia • Deprivation • Corneal Opacity
Refractive Amblyopia • Lid abnornalities • Ptosis • Hemangioma • Astigmatism
Refractive Amblyopia • Ectopia lentis • Refractive error • Myopia • Isometropia >-3.00 • Anisometropia >-2.00 • Aphakic Space?
Refractive Amplyopia • Hyperopia • Isometropia >4.50 • Anisometropia >1.50 • Astigmatism • Isometropia >2.00 • Anisometropia >2.00 • Combos
Rationale for Treatment • Career’s Choice (Stereopsis) • Risk of losing the other eye • Trauma • Degenerative Diseases • Prior to strabismus surgery!!!
Consequences of no Tx • Poor Vision • No stereopsis • Safety Glasses • Avoid contact sports
Patching • Up to 10 yrs • Time frame • New studies • Appointments • Complications
Eye drops for amblyopia • Atropine • Cyclopentolate • Complications
Co-management • Refers patients at risk • Education (good VA prior to Sx) • Appointments • Patch complications • Atropine complications
Conclusions • Risk factors • Causes • Treatment • Co-management • Young Adults
