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...

Summary

This summary is machine-generated.

Dengue Associated Maculopathy (DAM) can cause vision loss, but typically resolves on its own. Optical Coherence Tomography (OCT) aids in diagnosing and understanding different presentations of this dengue complication.

Medical Imaging

Background:

Dengue fever, a mosquito-borne viral illness, is known to cause diverse ocular complications.
Dengue Associated Maculopathy (DAM) represents a spectrum of visual disturbances affecting the macula.

Observation:

Two cases of Dengue Associated Maculopathy are presented.
Case 1: A 22-year-old female with dengue fever experienced vision loss in the left eye (20/40), with fundus showing macular exudates and hemorrhages, and OCT confirming cystoid macular edema.

Findings:

Case 2: A 33-year-old female with dengue presented with blurred vision (20/80) in the left eye; fundus revealed an elevated fovea with a distinct lesion, and OCT indicated foveolitis.
Both patients demonstrated favorable outcomes, with spontaneous visual recovery observed in both cases.

Implications:

This report underscores the necessity of anticipating and evaluating visual morbidity in dengue patients, even with generally benign outcomes.
Optical Coherence Tomography (OCT) is crucial for differentiating the varied presentations of Dengue Associated Maculopathy and guiding patient management.
