Images and diagnoses courtesy of James Lai, MD


63-year-old Caucasian female presenting with hypertension, hearing loss and Central Retinal Artery Occlusion (CRAO).


Utilizing the PrecisionFocus1 feature of the CLARUS® 700 from ZEISS, the swollen nerve and tiny yellow specs in the retina can be clearly observed in focus.


The single widefield True Color image on the ZEISS CLARUS 700 clearly shows a cherry red spot (1a) and swollen nerve, choroidal folds (1b).

In the fundus fluorescein angiography (FA) images, the delayed arterial venous transit can be seen (2a), and leakage is revealed consistent with disc swelling (2b) and decreased arterial perfusion.

Choroidal folds are visible in the FA early phase (3, time code: 0:25 second).

1PrecisionFocus feature allows you to quickly see the details in region of interest by selecting where to optimize focus, without losing the macula focal point.
