Although the patient selection criteria for implanting the mirror telescope are relatively simple, AMD patients differ in the degree of visual loss so how can we be sure that a certain candidate for the procedure will benefit from the implantation? The purpose of this presentation is to demonstrate a unique software program that helps in the patient selection process and identifies if a certain eye will improve by implanting the telescope.
Tel Aviv University medical Center, Department of Ophthalmology, Ichilov Hospital and OptoLight Vision Technologies, Herzlia, Israel.
A specially designed ETDRS based computer program (the OVT) was developed for testing if a certain eye will benefit from the mirror telescopic implant. The program allows testing of the patient before surgery (to determine if at least 3 lines of improvement in vision can be expected), it demonstrate to the patient what will be his vision after implantation, it presents the new contrast of the image that is received and it is also used for post op testing to find out if the expected results were achieved as well as for later follow up. As part of the validation process of the OVT we tested 10 patients by using the traditional optometric low vision testing and comparing the results of the 2 testing methods.
The OVT saves precious time by quickly screening patients before the treatment. A good correlation was found between the traditional optometric testing and the OVT. The differences were within +/- 1 ETDRS lines. By using the program the doctor was able to demonstrate to the patient what will the patients visual gain from the procedure, standardize the examination before and after the treatment and save a significant amount of time and it help in the patient education process.
The OVT was found to be a good tool for identifying if a certain patient is a good candidate for the implantation of the mirror telescope.
