摘要

Background

To investigate the association between Hemodialysis (HD) and postoperative outcomes in patients diagnosed with chronic renal failure (CRF) who underwent pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR).

Methods

This was a retrospective study. Fifty-three eyes were divided into HD (25 eyes) and non-HD (28 eyes) groups. Follow-up assessments were performed preoperatively and at 1 week, 2 weeks, 1 month, 2 months, 4 months, 8 months and 12 months postoperatively. Independent risk factors affecting visual recovery following PPV were also determined.

Results

The HD group exhibited significantly lower intraocular pressure (IOP) from 1 week to 2 months postoperatively compared to the non-HD group (P < 0.05). While non-HD patients had better preoperative best-corrected visual acuity (BCVA), HD patients achieved superior BCVA at 2 months (P < 0.05), with higher rates of visual improvement at 12 months (84.00% vs. 78.57%). Prolonged diabetes duration and elevated total cholesterol levels negatively correlated with postoperative VA prognosis (P < 0.05). The preoperative eye conditions, lens status, postoperative complications were not significantly different (P > 0.05).

Conclusions

Preoperative HD is associated with short-term reductions in IOP and improvements in BCVA after PPV, with long-term data correlating HD to better visual acuity outcomes. However, unmeasured confounders may influence these results. Prolonged diabetes duration and elevated total cholesterol levels also appear associated with slower visual recovery, warranting further validation.
