Angle Closure Glaucoma: Treatment

1.7K
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: 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

This study shows that vision rehabilitation using MAIA microperimetry successfully relocated the preferred retinal locus (PRL) in both eyes of a patient with adult pseudovitelliform dystrophy. This improved visual acuity by training eccentric viewing (EV).

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Vision Rehabilitation

Background:

  • Patients with low vision often use eccentric viewing (EV), utilizing extrafoveal retinal areas called the preferred retinal locus (PRL), which is associated with unstable fixation.
