[Cilioretinal arteries under fundus fluorescein angiography]
1Fourth Municipal Hospital, Xi-an.
Summary
Cilioretinal arteries are common, but angiography reveals they often don't supply the macula as thought. Ophthalmoscope diagnosis can be unreliable, underscoring the need for angiography to confirm these retinal vessels.
Area of Science:
- Ophthalmology
- Vascular Anatomy
- Medical Imaging
Context:
- Cilioretinal arteries are anomalous retinal arteries originating from the ciliary body.
- Their prevalence and anatomical variations are not fully understood.
- Clinical diagnosis can be challenging and prone to error.
Purpose:
- To determine the prevalence of cilioretinal arteries using fundus fluorescein angiography.
- To investigate the anatomical distribution and macular supply of these arteries.
- To assess the accuracy of ophthalmoscopic diagnosis compared to angiography.
Summary:
- Fundus fluorescein angiography revealed cilioretinal arteries in 40.2% of 2,050 eyes.
- In a subset of cases, these arteries supplied multiple quadrants but frequently did not perfuse the macula (52.3%).
- Angiography disproved ophthalmoscopic diagnoses in 21.7% of cases, highlighting diagnostic discrepancies.
Impact:
- Findings challenge the conventional belief about macular supply by cilioretinal arteries.
- Emphasizes the critical role of fluorescein angiography for accurate diagnosis and characterization of cilioretinal arteries.
- Highlights potential misdiagnosis based solely on ophthalmoscopy.
