[Report on renal transplant patients. Ocular changes due to renal disease and immunosuppressive therapy (author's transl)].

51 patients with renal transplants were examined ophthalmologically 31,1 (1--77) months after the transplantation. 80,4 p. c. showed ocular complications: cataract formation in 43,1 p. c. of the patients examined and increased intraocular pressure values between 22 and 30 mm Hg in 3 patients are to be attributed to the systemic immunosuppressive therapy. Further ocular changes were recurrent subconjunctival haemorrhages due to increased vascular rigidity, calcium phosphate deposits in the conjunctiva due to persistant secondary hyperparathyroidism and fundus changes (pigmentary irregularities in the foveal regions, narrow arterial vessels). Although marked arterial hypertension was observed in 21 patients after the transplantation, no signs of hypertensive retinopathy could be found. Despite the high incidence of ocular complications after renal transplantation the risks of immunosuppressive therapy must be considered as tolerable: cataract formation and increased intraocular pressure do not impair the positive effect of renal transplantation on ocular functions. Regular ophthalmological control examinations of renal transplant patients are advisable.
