Summary
Chikungunya virus infection can cause delayed optic neuropathy, a rare complication affecting vision. This case highlights a 69-year-old woman with vision loss due to Chikungunya virus (CHIKV).
Area of Science:
- Neurology
- Infectious Diseases
- Ophthalmology
Background:
- Chikungunya fever is a mosquito-borne viral illness causing fever, rash, and joint pain.
- Neurological complications of Chikungunya virus (CHIKV) infection are uncommon.
- Optic neuropathy is a rare but serious potential complication.
Observation:
- A 69-year-old woman developed acute unilateral optic neuropathy.
- This occurred as a delayed complication after Chikungunya virus (CHIKV) infection.
- Symptoms included painless visual field loss and optic disc swelling.
Findings:
- Serology confirmed recent CHIKV infection.
- The patient had a persistent relative afferent pupillary defect (RAPD) and optic atrophy.
- A corresponding inferior visual field scotoma was noted at 5-month follow-up.
Implications:
- This case illustrates a rare, delayed neurological manifestation of CHIKV.
- Optic neuropathy should be considered in patients with visual disturbances post-CHIKV infection.
- Prompt diagnosis and management are crucial for visual outcomes.

01:25Arboviral Encephalitis
30
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

01:25Glaucoma: 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...

01:27Open 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.

01:28Angle 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...

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

11.1K
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,...
