An introduction of PAM-1, a visual tester for your eyes

Visual function describes how well the eyes and basic visual system can detect a target stimulus. By varying a single parameter at a time (for example, the size of the target), testing is typically carried out in a repeated fashion under controlled testing conditions until a threshold of performance is obtained. In contrast, functional vision refers to how well an individual performs while interacting with the visual environment. That is to say, how their vision is used in everyday activities.

Gaush Raymond PAM-1 handheld visual function tester is used for routine visual function examination of ophthalmology.?It is?an instrument for detecting potential vision,?minimizes the influence of the refractive system. It can also be?used for preoperative vision prediction of cataract, quite useful for?routine detection before cataract extraction and intraocular lens implantation. Moreover, it?can also be used for retinal detachment, macular hole, penetrating keratoplasty and glaucoma preoperative prediction of visual function recovery. The auxiliary testing equipment has certain application value in evaluating the therapeutic effect of amblyopia and guiding the treatment of amblyopia.

The major clinical application for this visual function test covered by:

1. Cataract: Detect visual acuity after cataract surgery to ensure the medical effect
2. Amblyopia: differential diagnosis, curative effect judgment, detection and treatment
3. Keratopathy: Assess retinal function and predict visual acuity after treatment
4. Vitreous lesions: Judgment of retinal vision ability whether influenced by refractive system
5. Retinopathy: Evaluate of retinal vision before and after surgery

?It is slim in body size, available for carrying out under any circumstance, with battery charge mode, the products can be used as a convenient diagnosis tester for outpatient use. WIth 6 modes of fringe grating visual test ranging from 0.06~0.8, it sufficiently provides a quantified professional result for ophthalmology diagnosis.
