Glaucoma: Overview

Glaucoma: Overview

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...

Open Angle Glaucoma: Treatment

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: Treatment

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...

Summary

A rare intraocular nematode infection, Gnathostoma spinigerum, was identified in a patient from Odisha, India. Successful removal of the live worm from the anterior chamber and subsequent albendazole treatment led to complete recovery.

Area of Science:

Ophthalmology
Parasitology
Infectious Diseases

Background:

Intraocular nematode infections are uncommon, with most cases reported in Southeast Asia.
This case presents a rare instance of live intraocular nematode in India.

Purpose of the Study:

To report a case of intraocular nematode infection in a patient from Odisha, India.
To identify the causative agent and describe its successful management.

Main Methods:

Clinical examination including slit lamp biomicroscopy.
Surgical removal of the intraocular worm via anterior chamber paracentesis.
Morphological identification of the nematode by the Department of Microbiology.
Treatment with oral albendazole.

Main Results:

A 28-year-old female presented with chronic left eye symptoms including swelling, redness, lacrimation, pain, and diminished vision.
Slit lamp examination confirmed a live worm piercing the iris muscle.
The identified nematode was Gnathostoma spinigerum, based on its cephalic end morphology.
The patient achieved complete resolution of symptoms following albendazole therapy.

Conclusions:

Gnathostoma spinigerum can cause intraocular infections presenting with chronic ocular symptoms.
Early diagnosis and surgical removal, followed by antiparasitic treatment, are effective in managing this condition.
This case expands the geographical reporting of intraocular gnathostomiasis.
