Glaucoma: Overview01:25

Glaucoma: Overview

1.3K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

974
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.2K
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...

The Nucleolus02:55

The Nucleolus

10.3K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Cataract Surgery

Background:

  • Phacolytic glaucoma is a secondary angle-closure glaucoma caused by a hypermature cataract.
  • Inflammation and high intraocular pressure result from lens protein leakage.

Observation:

  • An 80-year-old female presented with acute eye pain and vision loss.
  • Examination revealed corneal edema, a turbid anterior chamber, and extremely high intraocular pressure (70 mm Hg).
  • Ultrasound biomicroscopy identified a hypermature cataract with a ruptured anterior lens capsule.

Findings:

  • Extracapsular cataract extraction was performed.
  • Cytology confirmed lens protein-laden macrophages.
  • Post-surgery, visual acuity improved to 6/60, despite pre-existing glaucomatous optic neuropathy.

Implications:

  • Phacolytic glaucoma can mimic endophthalmitis, necessitating careful diagnostic evaluation.
  • Ultrasound biomicroscopy is vital for accurate diagnosis in suspected phacolytic glaucoma.
  • Early intervention is key to managing intraocular pressure and preserving vision in these cases.
