Patch Clamp

Patch Clamp

Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

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
Dry Eye Disease Management

Background:

Punctal plugs have been a mainstay treatment for aqueous-deficient dry eye for over 30 years.
Despite their efficacy, punctal plugs possess inherent limitations in managing dry eye conditions.

Purpose of the Study:

To review the historical context of occlusive treatments for aqueous tear deficiency.
To provide an update on contemporary advancements in punctal and canalicular occlusive materials and techniques.

Main Methods:

Literature review of historical and recent advancements in punctal and canalicular occlusion.
Analysis of the evolution of materials and techniques used in dry eye treatment.

Main Results:

Punctal occlusion remains a significant therapeutic option for dry eye.
Recent innovations have expanded the range of available occlusive materials and methods.

Conclusions:

Punctal plugs are a valuable, though not exhaustive, tool for managing dry eye.
Ongoing research and development continue to refine occlusive strategies for aqueous tear deficiency.
