The Effect of Intranasal Pressure on Intraocular Pressure
Nasal surgery is one of the most frequently performed operations in otolaryngology practice.
Various nasal packs have been used after septal surgery to stabilize the mucoperichondrium
and bleeding.
Nasal packs increase intranasal pressure. The orbit, nose, and paranasal
sinuses are intimately related.
Human nose is well vascularized with arteries and veins, and
thus supplied with abundant blood.
Nasal veins have no vessel valves and direct communication
to the sinus caverns. Venous drainage of the nose and sinuses
is via the ophthalmic and facial veins, and the pterigoid and pharyngeal plexuses.
Intraocular pressure is a function of aqueous humor production and subsequent
drainage via the trabecular meshwork to ophthalmic veins and cavernous sinus.
Clinical studies have demonstrated that certain patients with primary
open-angle glaucoma suffer from reduced ocular blood flow,
which may be primarily of vascular origin or secondary to IOP elevation
The aim of this study was to evaluate IOP after the application of the nasal
packs for sinonasal surgery. Herein we present such a study to answer these features.
However, this increase was not statistically significant (p=0.115).
Likewise, post-operative intraocular pressure of the left eye increased from 16.00 mmHg to 16.75
mmHg. Again, this was not statistically significant.
