Ophthalmology · Retina: central retinal vein occlusion

Sample item

The fundus shows widespread flame-shaped haemorrhages, dilated tortuous veins and disc oedema in one eye. What is the diagnosis?

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

The answer and the reasoning

D. Central retinal vein occlusion

CRVO produces the blood and thunder fundus. Ischaemic types can lead to neovascular glaucoma 90 days after onset, so patients need close monitoring.

Option by option

  • A. Retinitis pigmentosa

    Retinitis pigmentosa shows bone-spicule pigmentation.

  • B. Central retinal artery occlusion

    Artery occlusion gives a pale retina.

  • C. Hypertensive retinopathy grade 1

    Hypertensive grade 1 shows only arteriolar narrowing.

  • D. Central retinal vein occlusion (correct)

    Correct. This is the typical fundus picture.
