Fundus photographic, fluorescein angiographic, and indocyanine green angiographic signs in successful laser chorioretinal venous anastomosis for central retinal vein occlusion1
Section snippets
Methods
This study reports on fundus photographs, sequential fluorescein angiograms, and indocyanine green angiograms in 15 consecutive cases of successful laser-induced chorioretinal venous anastomosis for central or hemicentral retinal vein occlusion treated by 1 retina specialist in a private practice. These cases are drawn from a larger population of 24 consecutive cases treated for this condition, of which 9 were unsuccessful. The time period for case accrual was June 20, 1995, through June 9,
Results
To help in orienting the reader, results will be presented in a parallel manner for the three methods of examination: fundus photography, fluorescein angiography, and indocyanine green angiography. For each of these methods, new signs will first be described and illustrated. The relative frequency of the new and previously reported signs will be reported next. Finally, the temporal sequence of development of the signs will be reported.
Discussion
The technique of laser chorioretinal venous anastomosis has evolved since its first description in humans by McAllister and Constable in 1995.1 Prominent among the changes has been recognition of better outcomes with higher argon laser power and abandonment of sole argon use in favor of a sequential technique in which the argon laser breaks through Bruch membrane, and the YAG laser punctures the adjacent, overlying retinal vein.4 It is recognized that earlier intervention probably is favorable

2008, Academic RadiologyCitation Excerpt :To date, most investigators have focused on the larger vessels of the pulmonary circulation due to the difficulty associated with measuring blood flow in the microcirculatory system. Fluorescein angiography is commonly used to qualitatively evaluate the circulation of the retina to detect and diagnose diseases, including diabetes (25,26). In addition to the use of fluorescein in ophthalmology applications, we believe that fluorescein has a potential use in determining changes in airway mucosa vasculature.
