Retinal Cases & Brief Reports
|January 14, 2017
Summary
This case report details a patient with central retinal artery occlusion who experienced sparing of two cilioretinal arteries. This finding suggests a second cilioretinal artery may be present in some central retinal artery occlusion cases.
Area of Science:
- Ophthalmology
- Vascular Medicine
- Retinal Imaging
Background:
- Central retinal artery occlusion (CRAO) is a critical condition causing sudden vision loss.
- Cilioretinal arteries, when present, can supply the macula and potentially preserve vision in CRAO.
- The prevalence and clinical significance of multiple cilioretinal arteries in CRAO are not well-established.
Observation:
- A 45-year-old woman presented with acute vision loss in one eye.
- Funduscopy and fluorescein angiography revealed evidence of central retinal artery occlusion.
- Two distinct cilioretinal arteries were identified, supplying small areas of normally perfused retina.
Findings:
- Spectral domain optical coherence tomography confirmed retinal thickening in the affected area, sparing regions supplied by the cilioretinal arteries.
- Over six months, retinal thinning occurred in the CRAO-affected areas, while the cilioretinal artery-supplied regions remained relatively preserved.
- The study documents the rare occurrence of double cilioretinal artery sparing in a CRAO patient.
Implications:
- This case highlights the potential protective role of multiple cilioretinal arteries in central retinal artery occlusion.
- The presence of a second cilioretinal artery may influence visual outcomes in patients with CRAO.
- Further research is warranted to understand the anatomical variations and clinical impact of cilioretinal arteries in retinal vascular occlusive events.
