[Quantitative function analysis of retinal circulation using videoangiography].

The choice of imaging technique to identify the presence of optic disc drusen has not been well established. We performed computed tomography (CT), magnetic resonance imaging (MRI), fundus fluorescein angiography and B-mode ultrasonography (B-USG) on four patients with optic disc drusen as the sole identifiable pathological process. CT, MRI and examination for autofluorescence demonstrated the presence of drusen in only one case each. B-USG showed characteristic features of optic disc drusen in all cases. We suggest that B-USG, a non-invasive and inexpensive technique, may be the imaging method of choice in identifying the presence of disc drusen.

Bilateral symmetrical branch retinal artery occlusions.

We present a report of a 52-year-old hypertensive patient with documented bilateral symmetrical branch retinal artery occlusions involving the maculae. The patient presented with no visual symptoms and maintained 6/5 unaided visual acuity in each eye. Although the incidence of retinal artery occlusion in hypertensive patients is well documented, symmetrical bilateral branch retinal artery occlusions suggest a possible anatomical vascular predisposition.
