What to expect at an SVOSH vision screening
Case History
Case history is essential to guiding the rest of the vision screening. By collecting information about the patient's ocular and medical health and visual needs, we are able to best serve the patient.
Visual Acuities
Visual acuities assess the patient's ability to discern letters on a chart. This gives us information on the patient's refractive status and if they have any pathologies affecting vision.
Cover Test
Using a cover paddle, we check the binocular alignment of patient's eyes.
Pupils
Checking the size, shape, and reactivity of pupils screens for neurological pathologies.
Slit Lamp Exam
A biomicroscope is used to take a microscopic look at the eye and assess its health.
Autorefraction
Autorefraction is a method to come up with a gross estimation of a patient's refractive error. This gives a starting point for a refraction.
Lensometry
A patient may come in with a pair of glasses. It is helpful to know what the prescription of their glasses are to have a starting place for a refraction.
Opthalmoscopy
Looking at the back of the eye is one of the most important parts of an eye exam and assesses a patient's ocular and systemic health. By looking at a fundus, we can detect signs of high blood pressure and even diabetes. We use a direct opthalmoscope or a binocular indirect opthalmoscope, and a variety of lenses to do this.
Retinoscopy
Retinoscopy is a rough objective evaluation of the refractive status of the eye. We use retinoscopy with a retinoscope to approximate a prescription for patients that may need a spectacle correction.
Tonometry
By using mobile tonometers like the ICare tonometer we can check the intraocular pressures of the eye. IOP is a huge indicator of ocular health, and high IOP may indicate glaucoma, making this an important screening tool.
