Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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

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...

Area of Science:

  • Ophthalmology
  • Medical research

Background:

  • Vitreous amyloidosis is a rare condition affecting the eye.
  • Understanding its clinical features and treatment outcomes is crucial.

Purpose of the Study:

  • To investigate the clinical characteristics of vitreous amyloidosis.
  • To evaluate the efficacy and safety of vitrectomy for treating vitreous amyloidosis.

Main Methods:

  • A cohort of 6 eyes from 4 patients diagnosed with vitreous amyloidosis was treated.
  • Vitrectomy was performed, and patients were followed up for 18-30 months post-surgery.

Main Results:

  • Pre-operative visual acuity ranged from counting fingers to 3/50.
  • Post-operative visual acuity improved significantly, ranging from 15/50 to 40/50.
  • No severe complications were reported following the vitrectomy procedure.

Conclusions:

  • Vitrectomy is demonstrated as a safe and effective treatment for vitreous amyloidosis.
  • Extended post-operative follow-up is advised for patients undergoing vitrectomy for this condition.
