The Bagolini striated glasses test, or BSGT, is a subjective clinical test to detect the presence or extent of binocular functions and is generally performed by an optometrist or orthoptist or ophthalmologist (medical/surgical eye doctor). It is mainly used in strabismus clinics.

There is no turning of lenses, as in Bagolini Striated Glasses Test which is another test measuring binocular functions, making the interpretation of the results less complicated; There are no large glasses frames such as in the Bagolini striated glasses test so the goggles are minimally obstructive to the patient's vision [1]
Test can be performed at any fixation distance - near or far; Results of the test can be checked/confirmed using Bagolini glasses, W4LT (macular torch) or Synoptophore; Post-strabismus surgery aim at times, can use in post-op review; When measuring the suppression scotoma, it needs to be done on cooperative patients
Static retinoscopy is performed when the patient has relaxed accommodative status. This can be obtained by the patient viewing a distance target or by the use of cycloplegic drugs (where, for example, a child's lack of reliable fixation of the target can lead to fluctuations in accommodation and thus the results obtained). Dynamic retinoscopy ...

Retinal vessel analysis is a non-invasive method to examine the small arteries and veins in the retina which allows to draw conclusions about the morphology and the function of small vessels elsewhere in the human body.
An examiner presents a test light of variable size and intensity. The light may move towards the center from the perimeter (kinetic perimetry), or it may remain in one location (static perimetry). The Goldmann method is able to test the entire range of peripheral vision and has been used for years to follow vision changes in glaucoma patients. [3]
