| Popis: | Purpose: To determine whether there are angiographic differences among normal, preperimetric and advanced glaucoma eyes using indocyanine green angiography with SLO. This method was chosen because of its sensibility to detect peripapillary capillary vessels. Methods: Scanning laser opthalmoscopy was preformed on normal eyes, preperimetric glaucomas and advanced glaucomas. Material: The authors used a confocal SLO (Heidelberg Retina Angiograph-HRA) Conclusion: Several changes may be seen on peripapillary capillary vessels at the different glaucomatous stages. Discussion: In normal subjects HRT shows preservation of the disc/cup area ratio; indocyanine green angiography shows normal prepapillary plexus pattern on the neuroretinal rim and cup. Subjects on glaucomatous preperimetric stage reveal a decrease in the disc/cup area ratio as a result of an increase of the cup area secondary to a reduction of the neuroretinal rim area. ICG at this hipertensive stage shows an increase in prepapillary plexus visualization, which may be a consequence of increased blood flow while autoregulation is still operative. Subjects with advanced glaucoma show prominent decrease in the disc/cup area ratio as well as marked capillary droupout in ICG angiography. |
