Sample item

Which fundus appearance is classically associated with central retinal vein occlusion?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Diffuse retinal hemorrhages with a blood-and-thunder appearance

Central retinal vein occlusion produces venous congestion, widespread retinal hemorrhages, dilated tortuous veins, and edema, often described as a blood-and-thunder fundus and requiring ophthalmic evaluation.

Option by option

  • A. A normal retina with no symptoms

    CRVO is symptomatic and produces fundus abnormalities.

  • B. Diffuse retinal hemorrhages with a blood-and-thunder appearance (correct)

    Correct: widespread hemorrhages and venous congestion are classic for CRVO.

  • C. A solitary white corneal opacity

    A corneal opacity is an anterior eye finding, not a retinal venous pattern.

  • D. A perforated tympanic membrane

    Tympanic membrane perforation is an ear condition.
