“…In conclusion, Murgatroyd and Bembridge [20] reported that IOP must remain within normal ranges to maintain optimum anatomical conditions for refraction and, thus, vision. When IOP is significantly elevated by conditions like glaucoma or sustained ST, it may be important to maintain stable ocular perfusion by elevating MAP or decreasing IOP.…”

Background: The purpose was to evaluate a level supine intervention (LSI) during laparoscopic surgery in steep Trendelenburg position (Lap ST). Increased intraocular pressure (IOP) and decreases in ocular perfusion pressure have been monitored during Lap ST procedures. Peri-orbital swelling and venous congestion in addition to IOP may produce a low perfusion state in the eye, via a compartment syndrome mechanism potentially exacerbated by trabecular meshwork dysregulated pressure dependent outflow. Research in rodent models has confirmed that in the ST position IOP can increase to critical thresholds of > 40 mmHg and studies have determined that even brief 30-40 minute episodes of acute IOP elevations can result in retinal cell ganglion (RCG) dysfunction. A LSI for one 5 minute interval at the 60 minute time point was introduced and was hypothesized to normalize IOP.

“…The production of aqueous humor is predominantly via an active secretory mechanism produced by a Na + K+ ATPase that creates an osmotic gradient for the passage of fluid into the posterior chamber‐ this is not influenced by IOP. There is a smaller pathway for aqueous humor production that is influenced by the blood pressure in the ciliary body capillaries, plasma oncotic pressure, and IOP . Glaucoma is an ocular disorder where there is increased intraocular pressure most commonly >22 mmHg.…”

It has been shown that patients with end‐stage renal disease (ESRD) have an increased risk for changes in intraocular pressure during hemodialysis, or ocular dialysis disequilibrium which can cause pain or discomfort during treatment and lead to decreased vision over time. This is a case of an elderly male with ESRD who was having headaches, nausea, and eye pain during hemodialysis due to increased intraocular pressures. Using a higher sodium prescription resolved his symptoms and normalized his intraocular pressures. This case illustrates that modification in dialysate tonicity can decrease changes in intraocular pressures while patients are on hemodialysis, a vision saving consideration for patients.
