The advantages of the A.V.I. Panoramic Viewing System in Vitreous Surgery by Stanley Chang, M.D.
4. Ability to visualize through a small pupil, intraocular lens or keratoprosthesis with a panoramic or wide field of view. Currently with conventional viewing, a small, limited field of view is achieved.
5. Improved ability to monitor the intraoperative injection of perfluorocarbon liquids so tat it does not go above the level of retinal breaks if traction persists.
6. Ability to visualize the peripheral retinal breaks in retinal detachments when none could be seen preoperatively.
7. Ability to see tractional relationships in proliferative vitreoretinopathy under perfluorocarbon liquids, such as: anteroposterior traction, anterior displacement of the retina, residual epiretinal membranes and star folds, subretinal membranes.
8. Improved visualization in the phakic or pseudophakic eye during fluid-air exchange for internal drainage and endophotocoagulation. Useful for applying growth factors or autologous serum onto macular holes.
