Vision Loss (Sudden, Painless in One Eye)
Sudden, painless vision loss in one eye—most commonly due to central retinal artery occlusion (CRAO)—is a medical emergency. This condition is often described as a “stroke of the eye,” where the blood supply to the retina becomes blocked, depriving it of oxygen. Without rapid treatment, permanent vision loss can occur within hours.
How HBOT Supports Retinal Recovery
At Under Pressure, we use Hyperbaric Oxygen Therapy (HBOT) to treat retinal artery occlusions by dramatically increasing the amount of oxygen delivered to retinal tissue through plasma. HBOT:
- Floods the retina with oxygen, bypassing the blocked artery
- Extends the survival window of ischemic retinal cells
- Reduces retinal edema and may improve blood flow post-occlusion
- Preserves partial or full visual function when used early
Studies suggest that patients treated within the first 24 hours have significantly better outcomes.
Symptoms of CRAO or Retinal Vision Loss
- Sudden blindness or dimness in one eye
- Painless onset with no trauma
- A curtain-like shadow over vision
- May be associated with cardiovascular risk factors
If you experience any of these symptoms, seek immediate emergency care. Delays can lead to irreversible vision damage.
Why Choose Under Pressure?
We offer urgent access to HBOT and collaborate with ophthalmologists, neurologists, and emergency teams to deliver time-sensitive care.
- Fast intake for acute vision loss referrals
- Direct coordination with your eye care provider
- Real-time progress tracking and follow-up evaluations
The treatment process
Initial consultation
- Emergency Assessment: We evaluate your eye exam, imaging (OCT, fluorescein angiography), and symptom timeline.
- Ophthalmology Collaboration: We work with your retina or neuro-ophthalmologist to confirm CRAO and rule out other causes.
- Eligibility & Timing: We prioritize treatment for patients within 6–24 hours of symptom onset.
Treatment Process
- During HBOT: The patient breathes 100% oxygen at increased pressure typically for 60-120 minutes, increasing oxygen diffusion to the retina through surrounding tissues.
- Treatment Schedule: Sessions may be repeated daily for several days depending on visual improvement and time since onset.
- Outcome Evaluation: Vision is monitored between sessions with visual acuity tests and follow-up retinal imaging.
Preparing for your HBOT treatment
- Pre-Treatment Guidelines:
- Bring all ophthalmic imaging and notes if coming from an eye specialist.
- Notify staff if you have a history of glaucoma, hypertension, or recent stroke.
- Avoid pressure on the affected eye.
- Post-Treatment Instructions: Rest and avoid activities that may increase intraocular pressure. Follow up with your ophthalmologist as directed.
Contraindications and Safety Information
- Who Should Avoid HBOT: Most CRAO patients can safely receive HBOT. However, caution is taken in those with retinal hemorrhage or active bleeding risks. Each case is reviewed thoroughly.
Expected Outcomes
- Recovery Timeline: Some patients regain partial vision within 24–72 hours, while others stabilize and prevent further loss.
- Long-Term Benefits: Early intervention with HBOT can preserve retinal function and reduce the risk of total blindness in one eye.
