For example, very large posterior tears are difficult to externally tamponade. Giant retinal tears do not respond to external buckle procedures because one cannot reappose the layers; the retina is merely pushed inward. In addition, the procedure can only work when all retinal breaks can be well visualized (Fig. 10.5). This may be difficult in eyes with media problems or
196 10 Retinal Detachment Repair: Outlook for the Future Fig. 10.5. A well-visualized peripheral retinal tear when intraocular lenses, retained lens material, and other difficulties preclude identification of all retinal breaks [2]. Let us now consider the evolution of surgical techniques in the future. One of the many obstacles to performing minimal buckling techniques, as well as pneumatic retinopexy and the balloon buckle, is the difficulty in finding all retinal breaks in certain eyes as outlined above. New techniques will evolve to allow visualization of the peripheral retina, which will make break identification more universally possible. New imaging techniques, such as ballistic light imaging (Fig. 10.6), hold the promise of high-resolution trans-scleral optical images [3]. Ordinarily, it is not possible to view clearly through a semi-transparent tissue, such as the thin sclera. A degraded image results due to scattered light. Light passes through the tissue, but scatter presents the ability to obtain a clear image. Scattered light is delayed compared with non-scattered light; however, the amount of delay is extremely small. The ability to fabricate femtosecond optical filters can theoretically gate out this scattered light based on time differences. In the future, such ballistic light imaging promises to be a non-invasive way of examining the vitre-
