| | Digital Angiography in Ophthalmology |
 | | Fluorescein angiography is an established technique for examining the circulation of the human retina. | | | Before any analysis of a fluorescein angiogram can be performed the individual frames of the angiogram must be digitised and registered to ensure that points in each frame correspond to identical positions on the retina. | | | It is the objective of this research to investigate the information which can be extracted from a digitised fluorescein angiogram with a view to quantifying changes in the circulation. |

| | By Deepak Gupta, O.D. Fluorescein angiography is an indispensable procedure that can help you investigate the integrity of the retinal vasculature. | | | It usually occurs secondary to other ocular or systemic conditions, and is mostly associated with cataract surgery with vitreous displacement. | | | This point of the study, the peak phase, is the optimal time to see the foveal avascular zone. |

| | Fluorescein angiography is most useful for studying the retinal circulation, whereas ICG is better suited for studying the deeper choroidal circulation. | | | The late or elimination phase shows the gradual elimination of dye from the retinal and choroidal vasculature. | | | ICG angiography is most frequently used when blood is present in the macula of patients with the wet form of macular degeneration because this may make interpretation of fluorescein angiography more difficult. |
