Access to Pediatric Eye Care Following Vision Screening
Journal of Pediatric Ophthalmology and Strabismus
|March 11, 2022
Summary
Most vision screening centers are accessible to optometrists within minutes and pediatric ophthalmologists within 70 minutes. Eye care access correlates with population density and income, favoring urbanized areas.
Area of Science:
- Public Health
- Ophthalmology
- Geographic Information Systems (GIS)
Background:
- Vision screening identifies potential vision impairments in children.
- Accessibility of follow-up eye care is crucial for timely treatment.
- Understanding geographic distribution of eye care providers is essential for public health planning.
Purpose of the Study:
- To quantify eye care provider accessibility from vision screening sites.
- To analyze accessibility in relation to population density and income.
Main Methods:
- Driving times were mapped using OpenStreetMap.
- Population density and median household income data were integrated using ArcGIS.
- Correlations between driving times and socioeconomic factors were analyzed.
Main Results:
- Median driving times to optometrists and ophthalmologists were 4.74 and 25.10 minutes.
- 90% of screening centers were within 12.46 minutes of an optometrist and 67.19 minutes of an ophthalmologist.
- Shorter driving times correlated with higher population density and median household income.
Conclusions:
- Most vision screening centers have reasonable driving times to optometrists and pediatric ophthalmologists.
- Accessibility is greater for optometrists than pediatric ophthalmologists.
- Eye care providers are concentrated in urban areas with higher socioeconomic status.

6.6K
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,...

2.0K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:27Open Angle Glaucoma: Treatment
728
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
858
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
935
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...
