Abstract

Background/aims: To evaluate changes in macular thickness measured by optical coherence tomography (OCT) during a hemodialysis (HD) session in diabetic patients with end-stage renal disease.

Methods: 72 eyes of 36 diabetic patients with and without macular edema were evaluated before and immediately after an HD session. Average and maximum macular thicknesses in the central disk (6 mm in diameter) and total macular volume were measured.

Results: In the eyes with diabetic macular edema, maximum macular thickness within the central disk of 6 mm, and mainly in its peripheral parts, was significantly reduced by 31.18 ± 4.18 μm after HD (p < 0.001). Average macular thickness and total macular volume were also significantly reduced (p = 0.003 and 0.015, respectively). In diabetic eyes without edema, maximum macular thickness decreased significantly by 11.21 ± 1.98 μm after HD (p < 0.001), while average macular thickness and total macular volume decreased slightly (p = 0.034, p = 0.043). Best-corrected visual acuity failed to change. We found a significant association of macular thickness changes with osmolality reduction and the presence of macular edema.

Conclusion: HD decreases macular thickness in diabetic patients with macular edema, while there exists a less-pronounced effect in diabetic eyes without edema.
