Fluorescein angiography in systemic hypertension

This study evaluates the role of fluorescein angiography (FA) in detecting changes in the retinal and choroidal capillary bed in hypertension and defines its advantages over direct ophthalmoscopy. 37 patients with varying degree of severity of hypertension were studied. Direct ophthalmoscopy and FA was done in all cases. No significant difference was found in documenting vessel calibre and arteriovenous crossing changes with either of the methods. Hard exudates were not visualized on FA. Capillary bed and choroidal abnormalities could be better studied on FA which can be employed in selected patients of hypertension but its use is not advocated as a routine in all hypertensives.
