Three major forms of Juvenile Macular Degeneration

Best’s Disease Juvenile Retinoschisis Stargardt Disease

All are rare and cause central vision loss

Stargardt Disease First report in 1901 German Ophthalmologist Karl Stargardt 1997 genetic component discovered

Recessive gene Both parents must have

Stargardt GeneStargardt No protein produced Without protein no energy No energy photoreceptor

cells in retina degenerates

Normal Gene produces

protein Protein produces

energy Energy sent to the

photoreceptor cells

Effects of gene defect

Fatty yellow pigment (Lipofusion) Build up under cells in macula Rods and Cones are affected Atrophy in the macula Loss of central vision Blindness

Symptoms Visual Acuity

20/40 20/200 Central Vision Loss Vision Acuity Blurry Vision Distorted Vision

Symptoms Dark Areas Color Perceptions Central Scotoma

(Blind Spot in Central Vision)

Night Blindness Photophobia

(Abnormal tolerance for light)

Treatments No Cure Current research:

UV Protective glasses may slow the progression Limit intake of vitamin A Stem cells in adult body fat

What is Age-Related Macular Degeneration (AMD)?

AMD is a condition that causes central vision loss

AMD is the leading

cause of vision loss for

people over the age of 60

Two Forms of AMD Dry Age-Related Macular Degeneration

More common Develops slowly

Wet Age-Related Macular Degeneration More severe Develops quickly

Causes of AMD?

Causes are unknown but possible risk factors include:

• Smoking• Obesity• Poor Diet• Exposure to UV

light

• High Cholesterol• Hypertension• Hereditary• Race• Gender

Symptoms of AMD

Blurriness Wavy Lines Blind Spot

Dry AMD Usually affects both eyes Light Sensitive cells in the macula begin to

breakdown and die Presents of Drusen

yellow spots under the retina

Wet AMD Abnormal blood vessel growth Blood and fluid leak under the macula Leads to scarring

TreatmentsDry AMD No cure or treatments Vitamins

Some studies show specific combinations of vitamins can slow the progression and impact

Wet AMD

No cure Treatments

Injections into the eye

Photodynamic Therapy

Laser Therapy

Tools to Detect Progression of AMD The Amsler Grid is a simple test to detect

early signs of AMD Demonstration of Reduced Visual Acuity

Case Study: Ernest Smith Age-Related Macular Degeneration Advanced Wet AMD in OS Caused by oxidative stress Used optical coherence tomography test Treatment available: Thermal Laser Therapy Daily monitor: Amsler Grid Had to have treatment again
