    OCT-A Proposed as Alternative to Iris Angiography

    A recent prospective study tested whether optical coherence tomography angiography (OCT-A) was useful in appraising anterior segment ischemia (ASI), a rare but potentially vision-threatening complication of strabismus surgery. 1 Researchers believe the invasive and time-consuming nature and potential adverse effects limit the utility of indocyanine green angiography and fluorescein angiography, the current standard for assessing anterior segment circulation. The study prospectively recruited nine adults undergoing strabismus surgery on at least one vertical muscle and evaluated images of 10 eyes. Indocyanine green angiography and OCT-A of the iris were taken preoperatively and one day post-op. The researchers found a 2% reduction ...
