Abstract:
To evaluate long-term visual changes in initially stronger fellow eyes in patients with unilateral Type 3 neovascularization. Methods: This retrospective study included 102 patients who were newly diagnosed with unilateral Type 3 neovascularization and in whom the best-corrected visual acuity (BCVA) of the fellow eye was initially better than that of the involved eye. All patients were treated with intravitreal anti–vascular endothelial growth factor injections. The BCVAs were compared at diagnosis, 12 months, 24 months, and the final visit. In patients who experienced ≥3 lines of visual deterioration in the BCVA of the fellow eye, the reason for visual deterioration was also verified. Results: The patients were followed for 45.9 ± 18.5 months after diagnosis. At diagnosis, the fellow-eye BCVA was better than that of the initially involved eye in all 102 patients. However, the fellow-eye visual acuity was the same or worse than that of the initially involved eye in 13 patients (12.7%) at 12 months, in 20 patients (19.6%) at 24 months, and in 24 patients (23.5%) at the final visit. At the final visit, 53 patients (51.9%) had experienced ≥3 lines of deterioration in the BCVA of the fellow eye. Fellow-eye neovascularization occurred in 42 patients, and geographic atrophy involving the fovea was noted in the remaining 11 patients. Conclusion: Deterioration of the visual acuity of the fellow eye is frequently noted in unilateral Type 3 neovascularization. As a result of this deterioration, the initially stronger fellow eye did not remain stronger in 23.5% of the patients, suggesting the need for long-term strict treatment of the initially involved eye even when the visual acuity of the fellow eye is good.
