Summary
Ocular syphilis, an eye infection from Treponema pallidum, saw a 100% increase in North Carolina from 2014 to 2015. Many patients experienced vision loss, but most improved after treatment.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Epidemiology
Background:
- Ocular syphilis is an inflammatory eye condition caused by Treponema pallidum.
- Syphilis rates have been rising in the US, with ocular syphilis clusters noted in 2015.
- This study examines the epidemiology and clinical course of ocular syphilis in North Carolina.
Purpose of the Study:
- To describe the epidemiology of ocular syphilis in North Carolina.
- To detail the clinical presentation and outcomes of ocular syphilis.
- To identify demographic and clinical factors associated with ocular syphilis.
Main Methods:
- Reviewed reported syphilis cases in North Carolina (2014-2015).
- Abstracted data from health department interviews for cases with ocular symptoms.
- Analyzed medical records and conducted interviews to assess symptom duration and severity.
Main Results:
- Ocular syphilis cases increased 100% from 2014 to 2015, outpacing overall syphilis increases.
- Ocular manifestations occurred across all syphilis stages, with 38% diagnosed in early stages.
- Reduced vision was reported by 87% of interviewed patients, with 31% experiencing residual symptoms.
Conclusions:
- Ocular syphilis incidence rose in North Carolina, possibly due to increased awareness or a true increase in cases.
- Vision loss is a common outcome, but most patients achieve visual improvement post-treatment.
- Early diagnosis and treatment are crucial for managing ocular syphilis and preventing long-term visual impairment.

1.3K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:27Open Angle Glaucoma: Treatment
1.0K
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
1.4K
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...

01:25Glaucoma: Overview
1.5K
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...

2.0K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
