Summary
High postoperative intraocular pressure (IOP) spikes are common after 23-gauge pars plana vitrectomy, especially in glaucoma patients or those receiving gas. Early IOP management is crucial to prevent spikes.
Area of Science:
- Ophthalmology
- Surgical Science
Background:
- Intraocular pressure (IOP) management is critical post-vitrectomy.
- Understanding risk factors for IOP spikes aids in patient care.
Purpose of the Study:
- To identify risk and protective factors for intraocular pressure spikes after 23-gauge pars plana vitrectomy.
- To describe outcomes and trends in postoperative IOP following this procedure.
Main Methods:
- Retrospective review of 97 eyes undergoing 23-gauge vitrectomy.
- Analysis of intraocular pressure and operative complications with at least 1-month follow-up.
Main Results:
- 73% of eyes with glaucoma and 76% with gas fill experienced IOP spikes.
- Early IOP-lowering drops reduced spikes (21% vs. 49%).
- Complications included retinal tears and detachments; no hypotony or endophthalmitis occurred.
Conclusions:
- Glaucoma and gas fill are risk factors for early postoperative IOP spikes.
- Proactive IOP management in the early postoperative period is recommended.
- Aggressive treatment may prevent significant IOP elevations.

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...
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.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
