Summary
Intravitreal triamcinolone injections for subretinal neovascularization can cause a significant rise in intraocular pressure. Approximately 30% of patients experienced this side effect within three months, highlighting the need for patient awareness.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Pharmacology
Background:
- Subretinal neovascularization (SRNV) is a significant cause of vision loss.
- Intravitreal corticosteroids are used to manage certain retinal conditions.
Purpose of the Study:
- To investigate the association between intravitreal triamcinolone acetonide and intraocular pressure (IOP) elevation.
- To assess the risk of IOP increase in patients with SRNV treated with intravitreal triamcinolone.
Main Methods:
- Prospective study involving 113 patients with angiographically confirmed SRNV.
- Monitoring of intraocular pressure as a key parameter following intravitreal triamcinolone administration.
Main Results:
- A significant IOP rise (≥5 mm Hg) was observed in approximately 30% of the study cohort.
- The IOP elevation occurred within the first three months post-injection.
Conclusions:
- Intravitreal triamcinolone treatment for SRNV is associated with a notable risk of increased intraocular pressure.
- Informed consent is crucial, detailing the potential ocular side effects of steroid injections.

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...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
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...
