Background
- Retinal hemorrhages are common at sleeping altitudes >16,000ft
Clinical Features
- Roth Spots: retinal hemorrhages with white center, seen on fundoscopy
- May be asymptomatic, or cause visual loss
Differential Diagnosis
Acute Vision Loss (Noninflamed)
- Painful
- Arteritic anterior ischemic optic neuropathy
- Optic neuritis
- Temporal arteritis†
- Painless
- Amaurosis fugax
- Central retinal artery occlusion (CRAO)†
- Central retinal vein occlusion (CRVO)†
- High altitude retinopathy
- Open-angle glaucoma
- Posterior reversible encephalopathy syndrome (PRES)
- Retinal detachment†
- Stroke†
- Vitreous hemorrhage
- Traumatic optic neuropathy (although may have pain from the trauma)
†Emergent Diagnosis
High Altitude Illnesses
- Acute mountain sickness
- Chronic mountain sickness
- High altitude cerebral edema
- High altitude pulmonary edema
- High altitude peripheral edema
- High altitude retinopathy
- High altitude pharyngitis and bronchitis
- Ultraviolet keratitis
Evaluation
- Clinical diagnosis
Management
- Not considered an indication for descent unless vision changes are present
