Glaucoma: Overview01:25

Glaucoma: Overview

484
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

413
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

375
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

5.5K
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,...

Prosopagnosia01:24

Prosopagnosia

120
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

COPD: Pathogenesis and Clinical Features01:20

COPD: Pathogenesis and Clinical Features

218
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Summary

Cogan syndrome, a rare systemic disease, can cause severe vision loss due to corneal clouding. Penetrating keratoplasty surgery significantly improved vision in a patient with this condition.

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Systemic autoimmune diseases

Background:

  • Cogan syndrome is a rare, progressive systemic inflammatory disorder.
  • Diagnosis is challenging, often relying on exclusion criteria.
  • Characterized by non-syphilitic interstitial keratitis and audiovestibular dysfunction.

Observation:

  • A 74-year-old female patient with Cogan syndrome presented with bilateral corneal opacification and decreased visual acuity.
  • The patient experienced progressive visual impairment affecting her right eye.
  • Underwent combined penetrating keratoplasty and cataract extraction.

Findings:

  • The surgical intervention resulted in significant visual improvement.
  • Keratoplasty is a viable treatment option for visual impairment in Cogan syndrome.
  • Early diagnosis and intervention are crucial for managing Cogan syndrome.

Implications:

  • This case highlights the potential benefit of keratoplasty in managing visual complications of Cogan syndrome.
  • Further research into diagnostic markers and treatment strategies for Cogan syndrome is warranted.
  • Ophthalmologists and rheumatologists should consider Cogan syndrome in patients with unexplained keratitis and hearing loss.
