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...

Photoreceptors and Visual Pathways

9.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

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

1.0K
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...

Hemodialysis II: Procedure and Complications

1.1K
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Hypertension III: Clinical Manifestations and Diagnostic Studies

644
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Summary

Vision loss from pre-eclampsia is rare but serious. Cortical blindness, a common cause, is usually temporary, with vision returning within 10 days. Effective management of pre-eclampsia is key.

Area of Science:

  • Obstetrics and Gynecology
  • Ophthalmology
  • Neurology

Background:

  • Pre-eclampsia and eclampsia can cause severe vision loss, including cortical blindness and retinal detachment.
  • These visual complications are uncommon but significant ocular issues in pregnant women.

Purpose of the Study:

  • To investigate the causes, clinical progression, and outcomes of blindness associated with pre-eclampsia.
  • To describe the incidence and specific types of visual impairment in pre-eclamptic patients.

Main Methods:

  • A prospective observational study was conducted from January 2006 to December 2010.
  • Sixteen women diagnosed with blindness complicating pre-eclampsia were analyzed for the cause, clinical details, and prognosis.

Main Results:

  • The incidence of blindness in pre-eclampsia/eclampsia was 0.17%.
  • Cortical blindness occurred in 14 patients, while 2 experienced retinal detachment.
  • Vision recovery in cortical blindness cases was typically within 10 days.

Conclusions:

  • Cortical blindness and retinal detachment are rare but significant ocular complications of pre-eclampsia.
  • Prognosis is generally favorable, particularly for cortical blindness, which is often transient.
  • Effective management of pre-eclampsia, including pregnancy termination, is crucial.
