This 65 year-old man
developed a central retinal vein occlusion six months ago.
Pan-photocoagulation was performed because of retina ischaemia. At the most
recent visit, the intraocular pressure was raised at 35mm Hg despite the
absence of obvious new iris vessels on slit-lamp examination. However,
gonioscopy revealed the presence of blood in the trabecular meshwork and
fine new vessels at the angle. Sometimes new vessels in central retinal vein
occlusion may begin in the angle instead of the pupillary edge. Gonioscopy
is useful to identify such vessels and further pan-photocoagulation should
be performed to induce regression of the vessels.

examination.
Blood in the angle of the
trabecular meshwork appearing as thick red line.
