Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

279
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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...

Microbiome of the Eye01:22

Microbiome of the Eye

67
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Summary

A significant number of young LASIK patients have undiagnosed dry eye (DES) with poor tear flow. Early detection and specific treatments are crucial to prevent complications like corneal erosion.

Area of Science:

  • Ophthalmology
  • Ocular Surface Disease

Background:

  • Increasing age is a known risk factor for dry eye syndrome (DES).
  • The study investigated DES prevalence in a young LASIK surgery candidate population.

Purpose of the Study:

  • Determine the prevalence of dry eye syndrome (DES) in young LASIK candidates.
  • Assess the use of post-operative dry eye medications in this population.

Main Methods:

  • Retrospective analysis of 948 patient charts undergoing LASIK surgery.
  • Patients classified into Normal, Pre-DES, and DES groups based on clinical evaluation and Schirmer's test.
  • Comparison of post-operative dry eye medication use across groups.

Main Results:

  • Only 2% of LASIK patients had a pre-operative diagnosis of overt DES.

  • 25% of patients classified as Pre-DES showed poor tear flow (≤ 5 mm) and used post-operative lubricants.
  • Pre-operative diagnoses underestimated the prevalence of DES and poor tear flow.

    • Conclusions:

    • A substantial proportion of young LASIK candidates exhibit poor tear flow without overt DES.
    • These individuals are at risk for developing serious ocular surface complications.
    • Targeted dry eye treatments and medications may be necessary for optimal management.
