Main causes
Retinal detachment
Retinal detachment should be considered if there were preceding flashes or floaters, or if there is a new
Glaucoma
Angle-closure glaucoma should be considered if there is painful loss of vision with a red eye, nausea or vomiting.[4] The eye pressure will be very high typically greater than 40 mmHg.[5] Emergent laser treatment to the iris may prevent blindness.[4]
Macular degeneration
Wet macular degeneration should be considered in older people with new distortion of their vision with bleeding in the
Giant cell arteritis
Giant cell arteritis should be considered in an older person with
Vascular occlusions
- Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye.[11]
- Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12]
- Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
- Branch retinal artery occlusion: BRAO may also cause acute painless loss of vision. [14]
Vitreous hemorrhage
It is one of the most common causes of acute or subacute decrease in vision. [15]
Hyphema
Blood in the anterior chamber of the eye is known as hyphema. Severe hyphema covering pupillary area can cause sudden decrease in vision.
