Summary
Intravitreal triamcinolone acetonide (IVTA) injections can lead to significant complications, including elevated intraocular pressure and, rarely, endophthalmitis or retinal detachment. Clinicians must weigh these risks when considering IVTA for eye conditions.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Ocular Surgery
Background:
- Intravitreal triamcinolone acetonide (IVTA) is frequently used for various retinal conditions.
- Understanding the associated complications is crucial for patient safety and informed treatment decisions.
Purpose of the Study:
- To comprehensively report complications following intravitreal triamcinolone acetonide injections in a tertiary care setting.
- To evaluate the incidence and types of adverse events associated with IVTA.
Main Methods:
- Retrospective case series review of 121 IVTA injections performed over 30 months.
- Analysis of indications, intraoperative events, and postoperative complications, including intraocular pressure (IOP) changes and vision-threatening events.
Main Results:
- No intraoperative complications were noted in 121 IVTA injections.
- Postoperative elevated IOP occurred in a significant percentage of eyes (46.5% ≥22 mmHg).
- Rare but serious complications included endophthalmitis (0.9%) and retinal detachment (1.8%).
Conclusions:
- Intravitreal triamcinolone acetonide injections are associated with considerable morbidity.
- Ophthalmologists should exercise caution and counsel patients on potential risks, including elevated IOP and severe ocular infections or detachments.

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...
