Description
Patients without previous contact lens experience were filmed with a video camera mounted on a slit lamp before initial contact lens insertion and again a minimum of one hour after initial wear. The entire 360 degrees of the corneal-scleral limbus was filmed for patients in the first section of the study. The limbal vascular arcades were seen to engorge in width and increase an average of .05mm in length. No vessels were found that extended over 0.50mm from the limbus. In addition to recording changes at the corneal-scleral limbus the
superior palpebral conjunctiva was filmed in the second section of the study. With one exception, no vascular changes were seen after at least one hour of wear after initial insertion of both hard and soft contact lenses. Several advantages and disadvantages of the method of videotaping in ocular research are listed in the discussion. Results of videotaping in this study were similar to results in other studies utilizing still photography. |
