Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Open Angle Glaucoma: Treatment01:27

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...

Angle Closure Glaucoma: Treatment01:28

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...

Area of Science:

  • Ophthalmology
  • Parasitology
  • Infectious Diseases

Background:

  • Intraocular parasitic infections are uncommon but can cause significant ocular morbidity.
  • Dirofilaria, a zoonotic nematode, can rarely manifest within the human eye.

Purpose of the Study:

  • To document a rare instance of a live intraocular Dirofilaria worm.
  • To describe its association with anterior uveitis and multifocal choroiditis.

Main Methods:

  • Observational case report detailing clinical presentation and management.
  • Slit lamp examination and indirect ophthalmoscopy were utilized for diagnosis.

Main Results:

  • A 43-year-old woman presented with acute symptoms including pain, redness, and decreased vision in the right eye.
  • A live Dirofilaria worm was identified in the anterior chamber, accompanied by multifocal choroiditis and retinal pigment epithelial changes.
  • Successful surgical removal of the worm and subsequent medical treatment with diethylcarbamazine citrate and topical steroids were performed.

Conclusions:

  • In Dirofilaria-endemic regions, parasitic infestation should be considered in patients presenting with multifocal choroiditis and retinal pigment epithelial tracts.
  • Early detection and intervention are vital to minimize ocular complications and visual impairment from such parasitic infections.
