Summary
This case study explores a Navy diver
Area of Science:
- Ophthalmology
- Hyperbaric Medicine
- Retinal Vascular Diseases
Background:
- A 47-year-old Navy diver presented with left-sided blurred vision.
- Initial diagnosis: left branch retinal artery occlusion.
- Complicated medical history impacting diving qualification.
Purpose of the Study:
- To present a complex case of vision loss in a Navy diver.
- To evaluate the efficacy of hyperbaric oxygen therapy (HBO2) for cilioretinal artery occlusion (CrAO) with paracentral acute middle maculopathy (PAMM).
Main Methods:
- Initial ophthalmologic examination and diagnosis.
- Initiation of hyperbaric oxygen (HBO2) therapy approximately 12 hours after symptom onset.
- Continuous surface oxygen therapy and daily HBO2 treatments over two days.
- Revised diagnosis to CrAO with secondary PAMM.
Main Results:
- HBO2 therapy provided temporary complete resolution of visual field defects.
- Surface oxygen therapy helped sustain visual improvement between HBO2 treatments.
- Final diagnosis revised to CrAO with secondary PAMM.
- Visual deficits evolved during treatment.
Conclusions:
- Hyperbaric oxygen therapy may offer temporary benefits for vision loss in CrAO with PAMM.
- This case highlights the complexity of diagnosing and treating rare retinal vascular events.
- Further research is needed to confirm HBO2's role in managing CrAO and PAMM.
