ULTRASOUND

We use our A and B Scan ultrasound equipment to examine the internal anatomy of the eye, employing the same principle technologies used in fetal ultrasound, although on a smaller scale. The sound beam delivered is reflected at interfaces of differing tissue densities and the reflected beam is received by the transducer. The reflected sound waves are analyzed to give further information about ocular structures. The transducer is placed directly on the eye with a soft contact lens in between, or on the eyelid, depending on the desired procedure. A-scan ultrasound is used to measure the corneal thickness. The measurement of corneal thickness is necessary in glaucoma management, extended wear of contact lenses and to check if individuals are suitable for lasik surgery (if corneas are too thin, and myopia too high lasik is not suitable). B-scan ultrasound displays the internal anatomy of the eye, allowing for evaluation of the retina when it is obscured by media opacities, as in the case of dense cataract and vitreous haemorrhage. B-scan ultrasound is also integral in the evaluation of ocular tumors and a variety of other ocular disorders.
