Summary
Meibomian gland dysfunction (MGD) involves abnormal keratin buildup, impacting tear film lipid layers and causing evaporative dry eye. This review explores keratin
Area of Science:
- Ophthalmology
- Dermatology
- Biochemistry
Background:
- Meibomian glands produce meibum, essential for the tear film's lipid layer.
- Meibomian gland dysfunction (MGD) impairs meibum production, leading to evaporative dry eye.
- Abnormal keratin production and aggregation at the meibomian gland orifice are implicated in MGD pathogenesis.
Purpose of the Study:
- To review the role of hyperkeratinization in the pathogenesis of meibomian gland dysfunction (MGD).
- To propose a novel treatment strategy for MGD targeting keratin proteins.
Main Methods:
- Synthesis of existing publications on hyperkeratinization and MGD.
- Analysis of the role of keratin proteins in MGD pathogenesis.
- Evaluation of keratolytic agents for MGD treatment.
Main Results:
- Hyperkeratinization is a significant factor in MGD development.
- Current MGD treatments often overlook the contribution of keratin proteins.
- Keratolytic agents, used in dermatology, show potential for MGD treatment.
Conclusions:
- Hyperkeratinization plays a critical role in meibomian gland dysfunction (MGD).
- Targeting keratin with keratolytic agents offers a novel therapeutic approach for MGD.
- Further research into keratolytic agents could lead to improved treatments for evaporative dry eye.

01:21Accessory Structures of the Skin: Sebaceous Glands
2.7K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

01:20Myasthenia Gravis: Overview and Treatment
2.1K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

01:27Open Angle Glaucoma: Treatment
748
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...

01:25Glaucoma: Overview
961
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...

01:28Angle Closure Glaucoma: Treatment
886
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...
