Ophthalmologic Diseases in Kidney Transplant Recipients: A Single-Center Prospective Study

Kidney transplant (KTx) recipients usually experience many comorbidities (eg, hypertension, diabetes, cardiovascular disease, glaucoma). They usually are older and have some ophthalmologic disorders, which may deteriorate after Ktx and some others may develop.

We aimed to review a 1-year examination of the eyesight characteristics in patients after KTx.

The study encompassed 82 eyes in 41 patients who underwent KTx in the years 2014 to 2018. All patients had visual acuity measurement, tonometry, slit lamp examination, and spectroscopic optical coherence tomography.

The most frequently observed changes during the 1-year observation were cataract (46%), hypertensive angiopathy (20%), and glaucoma (20%). One year after the renal transplant visual acuity declined in 22 patients (54%). In 45% of those with eyesight deterioration the cause was cataract, while in patients with no changes in eyesight (n = 9) cataract was not diagnosed. Patients with cataracts had been more often treated with high doses of steroids (steroid boluses), mainly because of acute rejection, which was significantly associated with cataract developing after Ktx (42% vs 11%; P = .019). On univariate analysis Charlson Comorbidity Index, total ischemic time, and steroid boluses were significantly associated with cataract developing after Ktx; none of these factors were an independent predictor on multivariate analysis.

The most common ophthalmologic diagnoses in patients after Ktx include cataract, glaucoma, and hypertensive angiopathy. Visual acuity deterioration, seen so often in the studied group of the patients, was mainly the effect of cataract progress. The effect of steroid boluses on cataract progress was meaningful.
