The impact of scheduled hemodialysis on clinical-functional and morphometric ophthalmological status of patients with a terminal kidney disease

Abstract

The literature review discusses the impact of scheduled hemodialysis on the state of the anterior part of the eye, the chorioretinal complex, the central and peripheral vision. The hemodialysis procedure is accompanied by a decrease in basal tear production, quickening of the tear film break-up, and an abnormal ocular surface disease index. Thinning of the corneal center is not accompanied by significant keratometric changes. Intradialytic thinning of the choroid and reduction of ocular perfusion pressure may be involved in the progression of ischemic eye diseases. Lower visual acuity is associated with the instability of the lens and choroid thickness. The impact of hemodialysis on the peripheral vision has not been sufficiently investigated. The correlations of ophthalmic changes with systemic effects of the dialysis are ambiguous. The inconsistency of the research results requires that the research should be continued.
