Long-term ocular complications after kidney transplantation.

Area of Science:

• Ophthalmology
• Nephrology
• Transplantation Medicine

Background:

• Kidney transplantation is a life-saving procedure, but long-term ocular complications can affect patient quality of life.
• Pre-emptive transplantation versus dialysis before transplantation may influence post-transplant outcomes, including ocular health.

Purpose of the Study:

• To evaluate long-term ocular complications in kidney transplant recipients.
• To identify factors, particularly pre-transplant dialysis status, associated with these complications.

Main Methods:

• A cohort of 548 kidney transplant recipients underwent comprehensive ophthalmologic examinations.
• Patients were categorized into two groups: pre-emptive transplantation (group 2) and dialysis before transplantation (group 1).
• Ocular parameters including visual acuity, refractive error, intraocular pressure, and anterior/posterior segment findings were recorded.

Main Results:

• Dry eye was significantly more prevalent in the pre-dialysis group (21.8% vs. 12%, p=0.003).
• Diabetic retinopathy incidence was significantly higher in the pre-dialysis group (25.3% vs. 16.2%, p=0.011).
• Refractive errors, cataracts, and other posterior segment conditions showed no significant differences between groups.

Conclusions:

• Dry eyes and diabetic retinopathy are common ocular complications following kidney transplantation.
• Patients who received dialysis prior to kidney transplantation face a higher risk of developing dry eye and diabetic retinopathy.
• Pre-transplant factors, such as dialysis status, play a crucial role in the development of ocular complications post-transplantation.
