oogtesten

Oogtesten, or eye tests, are a set of medical assessments used to evaluate visual function and the health of the eyes. They are used to determine refractive error, prescribe corrective lenses, screen for eye diseases, and monitor conditions that affect the eyes or systemic health.

Typical components include a visual acuity test to measure the sharpness of vision, a refraction assessment to determine the correct lens prescription, and an external and internal examination of the eye using a slit lamp and ophthalmoscope. Intraocular pressure measurement (tonometry) screens for glaucoma. Additional tests may include visual field testing for peripheral vision, color vision tests, and assessments of binocular function and accommodation.

Modern practices may include digital retinal imaging and optical coherence tomography (OCT). Some tests require pupil dilation with eye drops, which can blur vision temporarily. In many regions, these tests are performed by optometrists or ophthalmologists, while nurses or technicians may conduct preliminary measurements under supervision. Eye tests are offered in optometry clinics, ophthalmology departments, and community settings, and may be part of routine exams, pre-employment screenings, or sports clearance.

Children often undergo vision screening to detect refractive errors or eye alignment problems. In infants, specialized tests assess fixation and tracking. Adults are advised to have regular checks, especially with risk factors such as family history of eye disease, diabetes, hypertension, or advancing age. Results guide treatment, such as prescribing glasses or contact lenses, providing referrals, or initiating disease management.

Eye tests are not diagnostic on their own but are components of a comprehensive eye assessment. Abnormal results typically lead to follow-up examinations or referrals to a specialist.
