Summary
Intraocular pressure (IOP) elevation is common after intravitreal triamcinolone acetonide (IVTA) injections, especially with repeat treatments or baseline IOP over 16 mm Hg. Careful monitoring is crucial for patients receiving IVTA.
Area of Science:
- Ophthalmology
- Pharmacology
Background:
- Intravitreal triamcinolone acetonide (IVTA) is used for various ocular conditions.
- Monitoring intraocular pressure (IOP) is essential after IVTA administration.
Purpose of the Study:
- To determine the prevalence of IOP alterations following IVTA.
- To identify risk factors for IOP elevation after single and repeat IVTA injections.
Main Methods:
- Retrospective case series of 570 eyes receiving single IVTA and 43 eyes receiving repeat IVTA.
- IOP changes were defined as absolute elevation (≥5 or ≥10 mm Hg) and percentage increase (≥30% from baseline).
Main Results:
- Over 53% of eyes with single IVTA showed IOP elevation; 50.6% had ≥30% increase.
- Baseline IOP >16 mm Hg was a risk factor for IOP elevation.
- 65.1% of eyes receiving repeat IVTA experienced ≥30% IOP increase.
Conclusions:
- Elevated IOP post-IVTA is frequent, necessitating monitoring beyond 6 months.
- Patients with baseline IOP >16 mm Hg or undergoing repeat IVTA require close IOP surveillance.

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...
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...
