Glaucoma: Overview01:25

Glaucoma: Overview

1.5K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.4K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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.

Ophthalmic Drug Delivery Systems

103
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
  • Medical Imaging

Background:

  • Free-floating intraocular cysts are rare ocular findings, occurring in the anterior chamber (FZV) and vitreous (FZG).
  • First described 150 years ago, these cysts remain uncommon and their origins are not fully understood.

Purpose of the Study:

  • To present current knowledge on FZV and FZG using two patient cases.
  • To discuss potential etiologies and management strategies for intraocular cysts.

Main Methods:

  • Case study approach detailing two patients with intraocular cysts.
  • Utilized ultrasound biomicroscopy for cyst characterization.
  • Reviewed literature on cyst classification, origins, and treatment.

Main Results:

  • Patient 1: Incidental FZV with smooth, translucent, slightly pigmented surface; ultrasound showed an echo-free interior. A watch-and-wait approach was adopted.
  • Patient 2: FZG with reduced transparency, unpigmented, yellowish-greenish surface; ultrasound revealed an echo-free interior. Clinical monitoring was advised.
  • Discussed primary (pigment epithelium) and secondary causes for FZV, and congenital/acquired causes for FZG, noting unclear genesis.

Conclusions:

  • Accurate diagnosis and documentation (photographic, sonographic) are vital for managing FZV and FZG.
  • Understanding potential causes is essential for informed therapeutic decisions in managing these rare intraocular cysts.
  • A watch-and-wait strategy may be appropriate for asymptomatic cysts, emphasizing the need for careful monitoring.
