Summary
Intraocular pressure (IOP) generally decreases after hemodialysis due to increased plasma colloid osmotic pressure (COP). However, long-term hemodialysis patients may experience an IOP increase.
Area of Science:
- Ophthalmology
- Nephrology
- Internal Medicine
Background:
- Hemodialysis is a critical treatment for end-stage renal disease.
- Understanding its systemic effects, including ocular parameters like intraocular pressure (IOP), is essential.
Purpose of the Study:
- To investigate the changes in intraocular pressure (IOP) following hemodialysis.
- To identify factors influencing IOP fluctuations in patients undergoing hemodialysis.
Main Methods:
- A prospective, observational case series involving 95 patients (188 eyes).
- Measurements included intraocular pressure (IOP), blood pressure, and plasma colloid osmotic pressure (COP).
Main Results:
- A significant decrease in IOP was observed post-hemodialysis (P = 0.006).
- Hemodialysis also led to significant reductions in body weight, blood pressure, and a significant increase in COP (P < 0.001).
- IOP changes correlated negatively with COP and positively with body weight changes.
Conclusions:
- The observed decrease in IOP during hemodialysis is likely attributed to an increase in plasma colloid osmotic pressure (COP).
- Patients with over 12 years of hemodialysis treatment showed a tendency towards increased IOP post-procedure.

01:24Hemodialysis II: Procedure and Complications
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
