Optometry clinic opens doors to Active Duty dependents, and diabetics
Capt. Shirley De La Rosa, 2nd Aerospace Medical Squadron Optometrist, conducts a Binocular Indirect Ophthalmoscopy, or BIO, on Chizu McCasland at Barksdale Air Force Base, La., Oct. 22, 2015. The BIO provided the optometrist a wider view of the retina and vitreous through a dilated pupil. Using this technique, they diagnose the health of the interior of an eye.
