Klin Monbl Augenheilkd. 2015 Apr;232(4):519-24. doi: 10.1055/s-0034-1396327. Epub 2015 Apr 22.


Background: The aim of this study was to evaluate characteristic findings and functional outcome of this rare type of retinal vascular occlusion in a large patient series.

Patients and methods: A retrospective chart review of all patients with a cilioretinal artery obstruction (CAO) seen at the University Eye Clinic Mainz (Germany) over a ten-year period between 1/1999 and 12/2008 was undertaken. The mean follow-up amounted to 42 months.

Results: Thirty-three eyes were diagnosed with CAO. Three distinct groups were differentiated: (i) isolated CAO in 20/33 eyes; visual outcome achieving 20/50 in 17/20 eyes; (ii) CAO combined with central retinal vein occlusion in 9/33 eyes; visual outcome achieving 20/50 in 5/9 eyes; (iii) CAO combined with anterior ischaemic optic neuropathy in 4/33 eyes; associated with giant cell arteriitis in 4/4 eyes; visual outcome achieving 20/160 in 1/4 eyes.

Conclusions: The visual prognosis of CAO is significantly better than for other types of retinal artery occlusions, with the exception of cases associated with giant cell arteriitis.
