|October 24, 2001
Summary
New treatments for retinal degeneration face delivery challenges. Transscleral delivery shows promise for effectively reaching posterior eye tissues, improving drug concentration for treating posterior segment eye diseases.
Area of Science:
- Ophthalmology
- Pharmacology
- Biomedical Engineering
Background:
- Retinal degenerations and posterior segment eye diseases are visually devastating conditions.
- Current treatments are limited by the difficulty of delivering drugs to target tissues in the posterior eye (vitreous, retina, choroid).
Purpose of the Study:
- To review recent laboratory and clinical studies on transscleral drug delivery.
- To assess the potential of transscleral delivery for treating posterior segment eye diseases.
Main Methods:
- Review of existing laboratory and clinical research.
- Analysis of studies investigating transscleral delivery of therapeutic agents.
Main Results:
- Transscleral delivery is a potential method for achieving therapeutic drug concentrations in the posterior segment of the eye.
- This approach may overcome current limitations in drug delivery for posterior eye diseases.
Conclusions:
- Transscleral delivery offers a promising strategy for treating retinal degenerations and other posterior segment eye conditions.
- Further research and clinical application of transscleral delivery could significantly improve patient outcomes.

Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

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...
