Title

The Effect of Contact Lens– spectacle Reversed Galilean Telescope on the Visual Field of Patients with Open-angle Glaucoma

Pages

  502-508

Abstract

 Purpose: Glaucoma causes irreversible Visual Field defects. This study aims to evaluate the effect of a Reversed Galilean Telescope on the Visual Field of patients with open-angle Glaucoma. Methods: Fifty-two Glaucoma patients with a restricted Visual Field were recruited for this study. Central 30° Visual Field measurements were performed using a Humphrey Visual Field analyzer before and after applying the Reversed Galilean Telescope. To be more cosmetically acceptable, a combination of contact lens– spectacle was used as the Reversed Galilean Telescope. Results: Our data analysis showed that the Reversed Galilean Telescope had a significant effect on all measured perimetric indices. Visual Field index (VFI) improved from a basic value of 44. 38 ± 26. 96 to 49. 30 ± 29. 83 percent by using the reversed telescope (P < 0. 001). Moreover, the mean deviation (MD) was significantly improved from the initial value of – 19. 91 ± 7. 19 dB to a value of – 18. 69 ± 7. 73 dB (P < 0. 001). However, our results showed a significant reduction in the pattern standard deviation (PSD) comparing before (9. 83 ± 2. 82) and after (8. 51 ± 3. 30) values using the Reversed Galilean Telescope (P < 0. 001). Conclusion: The contact lens– spectacle combination Reversed Galilean Telescope significantly improved the central 30° Visual Field of Glaucoma patients with the restricted Visual Field.
