Driving a Heavy Motorcycle with Amblyopia – a Case Report

March 18, 2024

Patients with adult amblyopia (lazy eye) are often told that their vision cannot improve beyond what conventional treatments have already achieved.

RevitalVision has shown that this is not always the case. Through perceptual learning and cortical stimulation delivered via our web-based training platform, adults with amblyopia can achieve meaningful improvements in visual performance, often beyond what they believed was possible.

One such patient is Yehuda.

Yehuda, 55, was born with severe anisometropic amblyopia. Because his condition was not properly treated during childhood, he lived with reduced vision in his amblyopic eye for most of his life.

For years, Yehuda dreamed of obtaining a heavy motorcycle license. However, he was unable to meet the visual requirements needed to pass the licensing exam. Multiple eye care professionals told him that there was nothing more that could be done to improve his vision.

Then he discovered RevitalVision and realized that there is Amblyopia treatment for adults.

After approximately three months of training, Yehuda achieved a significant improvement in his visual performance. He successfully passed the vision test required for a heavy motorcycle license and fulfilled a lifelong dream that once seemed out of reach.

Here are the case report details:

Following a baseline vision exam, the patient began the RevitalVision home-based vision-training program and returned to the clinic for a follow-up exam every 20 training sessions. The patient trained monocularly (LE) with contact lenses and completed a total of 60 sessions.

RX: CL
RE -2.75/-0.50 x121
LE +4.75/-2.50 x85

Baseline examination:
Distance VA: RE: 6/6 / 20/20
LE: 6/12 (-2) / 20/40 (-2)
Near VA: RE: J1+
LE: J5

Stereopsis: 400 SOA
Worth 4 Dot: Suppression

Examination after 20 sessions:
Distance VA: RE: 6/6 / 20/20
LE: 6/9 / 20/30 (-1)
Near VA: RE: J1+
LE: J4

Stereopsis: 70 SOA
Worth 4 Dot: Fusion

Examination after 40 sessions:
Distance VA: RE: 6/6 / 20/20
LE: 6/9 / 20/30
Near VA: RE: J1+
LE: J1 (-2)

Stereopsis: 70 SOA
Worth 4 Dot: Fusion

Examination after 60 sessions:
Distance VA: RE: 6/6 / 20/20
LE: 6/7.5 (-1) / 20/25 (-1)
Near VA: RE: J1+
LE: J1(-2)

Stereopsis: 50 SOA
Worth 4 Dot: Fusion

The patient demonstrated an improvement of 2.5 VA lines for distance, 4 VA lines for near, and experienced a significant stereopsis improvement and anti-suppression effect. The patient reported better vision when reading subtitles on TV and in his day-to-day life, and was able to achieve his lifelong dream of obtaining a license for a heavy motorcycle.
