Early Onset of Neovascular Glaucoma After Intra-Arterial Thrombolysis for Central Retinal Artery Occlusion: A Possible Complication?

PURPOSE: To report on four cases of central retinal artery occlusion (CRAO) treated with intra-arterial thrombolysis with early onset neovascular glaucoma in the further disease course.

PATIENTS AND

METHODS

Retrospective analysis of the medical records of six consecutive patients treated with intra-arterial thrombolysis for CRAO of which four developed neovascular glaucoma.

RESULTS

All six patients were diagnosed with acute CRAO and treated with intra-arterial thrombolysis 4.5-6 hours after symptom onset. The patients had no significant carotid artery stenosis and unremarkable ophthalmic history. No visual improvement could be achieved after treatment. Four to seven weeks after CRAO onset, four of these patients developed severe painful neovascular glaucoma.

CONCLUSION

Early onset of aggressive neovascular glaucoma following intra-arterial thrombolysis for CRAO might be a complication of CRAO itself, still possible association with intra-arterial thrombolysis in our patients should be discussed.
