Summary
Intraocular pressure elevation affects about 24% of patients within a day after vitrectomy. Key risk factors include laser photocoagulation, combined cataract surgery, and gas tamponade use.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Retinal Surgery
Background:
- Vitrectomy is a common surgical procedure for various vitreoretinal disorders.
- Monitoring intraocular pressure (IOP) post-vitrectomy is crucial for patient management.
- Understanding risk factors for IOP elevation can guide surgical planning and postoperative care.
Purpose of the Study:
- To determine the incidence of intraocular pressure (IOP) elevation in the immediate postoperative period after vitrectomy.
- To identify risk factors associated with postoperative IOP elevation following vitrectomy for vitreoretinal disorders.
Main Methods:
- Prospective study of 228 consecutive patients undergoing vitrectomy.
- Intraocular pressure (IOP) measured preoperatively, end of surgery, 5 hours, and 1 day postoperatively.
- Tono-Pen XL used for IOP measurements; IOP adjusted to 15.0 ± 2.0 mm Hg at the end of surgery.
Main Results:
- IOP elevation (>25 mm Hg) observed in 24.1% at 5 hours and 22.8% at 1 day postoperatively.
- Specific vitreoretinal disorders showed significant differences in IOP levels at 5 hours and 1 day.
- Risk factors identified: laser photocoagulation, preoperative IOP, combined cataract surgery, 20-gauge vitrectomy, postoperative vitreous hemorrhage, and expanding gas tamponade.
Conclusions:
- Approximately one-quarter of patients experience IOP elevation within 1 day after vitrectomy.
- Laser photocoagulation, combined cataract surgery, postoperative vitreous hemorrhage, and expanding gas tamponade are significant risk factors for IOP elevation.
- These findings highlight the importance of vigilant IOP monitoring and risk factor management post-vitrectomy.

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...
