Prevalence and sociodemographic characterization of ocular diseases of infectious origin in the Colombian population from January 1, 2015 to December 31, 2019.

Project: Research Project

Project Details


Multiple local or systemic infectious diseases can
compromise ocular and periocular structures.

Among these, it is worth highlighting tuberculosis, toxoplasmosis and the varicella zoster virus (VZV) due to their high prevalence.

It has been described that up to the world's population has had VZV infection, 30% by tuberculosis (TB) and 30% by toxoplasmosis.

These three infections can cause ocular involvement and irreversible complications that lead to visual impairment.

Tuberculosis is an infection caused by the bacteria Mycobacterium.
tuberculosis, which can generate multiple manifestations
pulmonary and extrapulmonary.

Among the extrapulmonary manifestations, ocular infection can represent from 1 to 26% of cases, depending on the geographic location analyzed.

Ocular herpes zoster (HZO) is defined as a reactivation of VZV in
the V1 branch of the trigeminal nerve.

It can cause complications such as glaucoma, cataract, corneal scars and postherpetic neuralgia (PHN) that can greatly compromise visual function and quality of life.

Ocular toxoplasmosis (OT) is an infection caused by the intracellular protozoan parasite Toxoplasma gondii (Tg) and is the most common etiology of posterior uveitis in the world.

In Colombia, 47% of the population has positive antibody titers for Tg and it is estimated that 1,000,000 people have retinochoroidal scars.

Taking into account the absence of specific data on general prevalence and by region in Colombia, this project aims to describe the prevalence and sociodemographic characteristics of ocular diseases of infectious origin in the Colombian population, according to data from the Comprehensive Information System of the Social Protection (SISPRO) between the periods from January 1, 2015 to December 31, 2019.
