For #TriviaTuesday this week we have these instruments. They are from the mid 20th century and are 36.5 cm in length. Any ideas what they are used for?

which could be why earlier perimetry studies failed to find anything.. (should try perimetry/retinotopy with red/black stimuli)

5/7 Kromě toho tam byly i ochranné a patrolové úkoly (doprovody, patroly, ochrana základen/letiště), které běžně znamenají pohyb mimo bezpečné perimetry a reálné riziko útoků.

Perimetry Test (Visual Field Testing) for Glaucoma
A perimetry test (visual field test) measures all areas of your eyesight, including your side, or peripheral, vision. To do the test, you sit and look inside a bowl-shaped instrument called a perimete...

The Ancient Echoes bosses are both centered around surviving a hostile plasma cloud. The Haunted Nebula fills the screen & you need to pick out weak spots to shoot to dissipate it. I was inspired by a perimetry visual test(?).

Tady jsou nožičky napevno, ale počkej zrovna u toho jednorožce ukážu... jsou to docela masivní články jako u řetězu - schválně tisknu 3 vnější perimetry, aby to byla stěna tlustá cca 1.2 mm - docela odolné, řekl bych. A hlavně: www.medvjed.store/nahradni-dil...

Na dovolenou jsem vytiskl takováhle letadélka.
A lítají teda velmi dobře.
Co tisknete na dovču vy? Inspirujte mě a další 3D tiskaře 🤗

I have an Antrim Accent Challenge for you.
Attempt to say the phrase “Automated Static Perimetry” quickly
(I had to say this in an exam, whilst extremely nervous, to a person from London 😬.)

🔍 7,917 eyes with glaucoma:
When <0 dB VF points (floor) were retested:
• Std→Std: ~10.3% <0 dB → ≥7 dB
• Std→Fast: ~15.8%
• Std→Faster: ~25.5%
⬆️ Effect strongest in macula.
⚠️ Faster tests may show false “improvement,” masking progression.

I can only make sense of this by supposing that despite negative prior perimetry/retinotopy studies, the patient *does* have a very very narrow surviving channel from early VC - like a narrow point or speck in the former visual field - that maybe carries *only* certain color signals..

Comparison of Far Peripheral Visual Fields in East-Asian and Caucasian Subjects
Visual field defects, characterized by diminished or lost vision within the visual field, can arise from various ocular or neurological conditions.1,2 Consequently, assessment of these defects plays a crucial role in the diagnosis and management of a wide range of ocular and neurological disorders. Various clinical tests have been developed to evaluate visual field defects. Static and kinetic perimetry provide unique insights into the visual field. Static perimetry provides quantitative data on the sensitivity of different regions within the visual field.
