Laboratory Studies

Extensive laboratory testing for retinal vein occlusion is not indicated. The yield from general laboratory tests for central retinal vein occlusion (CRVO) is low. Such laboratory workup may be prudent in unusual case presentations or in bilateral CRVO, in which systemic causes are more prominent etiological factors. Younger patients are more likely to have an underlying coagulopathy, and patients younger than 45-50 years who lack identifiable cardiovascular risk factors should be screened for coagulopathy by the primary doctor in consultation with the ophthalmologist.


Imaging Studies

Fluorescein angiography: The presence and severity of ischemia cannot be reliably determined at the time of physical examination in the ED. As part of the outpatient ophthalmological examination, fluorescein angiography is usually performed at the discretion of the eye specialist.
