This study aimed to quantify visual and retinal changes in patients with bipolar disorder (BD) over a 5-year period. The results showed that visual function parameters remained unchanged during the follow-up period, but there was a progressive decrease in retinal thickness. The progressive changes in BD were more significant compared to the healthy controls. Furthermore, a correlation was found between changes in ganglion cell layer (GCL) thickness and disease duration.
Purpose To quantify visual and retinal changes in patients with bipolar disorder (BD) over 5 years, compared with controls. Methods Thirty-eight patients with BD and 122 healthy subjects underwent visual acuity (VA) evaluation, contrast sensitivity vision testing (CSV) with the Pelli Robson and CSV 1000E tests, and retinal thicknesses measurement [ganglion cell layer (GCL) and retinal nerve fiber layer (RNFL)] using Spectralis Optical Coherence Tomography (OCT). All subjects were re-evaluated after 5 years. The relationship between progressive structural changes and disease duration was analyzed. Results Visual function parameters in BD patients remained unchanged during the follow-up period. A progressive decrease affecting macular and peripapillary RNFL thickness (p < 0.050) was observed in patients. Progressive changes in BD were more pronounced when compared with healthy controls (p < 0.050). A significant correlation between GCL thickness changes and disease duration was found (GCL outer temporal, r = -0.680, p = 0.016; GCL central, r = -0.540, p = 0.038). Conclusions Progressive axonal loss was detected in BD patients. Visual function parameters were not affected after the 5-year follow-up. Despite observed changes in the neuroretina of patients with BD, axonal degeneration in these patients seemed to be mild and might be slowed down by other factors, such as BD treatments.
