Primary Retinal Detachment

Retinal Detachment Repair: Outlook for the Future 197
Fig. 10.6. Trans-scleral retinal imaging (scattering media)
ous base area at high resolutions and will be particularly helpful in
cases of small pupils, intraocular lenses with anterior capsular phimosis,
and other conditions. A trans-scleral imaging probe could
be used with topical anesthesia and would allow thorough examination
of the peripheral retina at high magnification, similar to
how ultrasound is currently used. Additional imaging techniques,
which may be applicable to detect retinal breaks, include higher
resolution and intraoperative ultrasound biomicroscopy that is
easier to use (Fig. 10.7). Current techniques are limited by awkwardness
of probe placement and large instrumentation; but, this
should change in the future. The use of ultrasound will not actually
visualize retinal breaks optically; however, clearly, breaks can be
identified by ultrasound, particularly using high-resolution techniques.
Ophthalmoscopic techniques that involve visualization of
the retina through the optical media of the eye are also evolving;
