Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

Angle 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...

Ophthalmic Drug Delivery Systems

Ophthalmic 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...

Area of Science:

Ophthalmology
Retinal Diseases
Ophthalmic Surgery

Background:

Intravitreal injections (IVIs) are a cornerstone treatment for various retinal diseases.
Standardized practice patterns are crucial for optimizing patient outcomes and minimizing complications.

Purpose of the Study:

To delineate the current practice patterns of intravitreal injections (IVIs) among ophthalmologists in China.
To identify areas for potential standardization and improvement in IVI procedures.

Main Methods:

A cross-sectional, anonymous online survey was conducted among ophthalmologists in China.
Participants had performed over 100 IVIs and were queried on pre-injection, injection, and post-injection techniques and procedures.

Main Results:

333 ophthalmologists responded, with high adherence to safety measures like prophylactic antibiotics (100%) and sterile techniques (e.g., masks 99.7%, gloves 99.4%).
Variations were noted in pupil dilation (61.26%), bilateral injections (51.05%), and post-injection assessments (IOP 32.43%, optic nerve perfusion 36.94%).
The superior temporal quadrant was the most common injection site (40.54%), with 30-gauge needles frequently used (approx. 75%).

Conclusions:

The study provides a comprehensive overview of real-world intravitreal injection practices in China.
Findings offer valuable insights for refining ophthalmologist education, training programs, and local society guidelines for IVIs.
