Spiraling, Crossing, or Stacking of isopters on Goldmann visual field. Cloverleaf pattern on automated visual field This may manifest as decreased visual acuity which ranges from difficulty seeing small objects to total blindness. Another manifestation is visual field defects which are dark or absent areas in the patients vision from which no images are formed. Visual loss can arise due to problems in the eyes or in the nervous system

A star-shaped field is also characteristic of psychogenic or feigned visual complaints, and is produced when the technician tests successive meridians from both sides before proceeding to the next one.28 However, it should be noted that spiral and star-shaped fields are actually the result of poor reproducibility and can therefore also be seen. Other visual field abnormalities, including spiral, helical or star-shaped fields are also important in hysteria.(6,7) Schlaegel and Quilala(8) pointed out that the size of the tubular fields were constant in hysteria on suc-cessive examinations.

Visual migraine. The most common cause of kaleidoscopic vision is a visual migraine. This may also be called an ocular or ophthalmic migraine. The technical term for it is scintillating scotoma.

In the spiral field, as the examiner brings the stimulus in from the periphery on one meridian after another, the patient's criterion for responding gradually changes and the resultant isopter takes on the form of a spiral ( Thompson, 1985 )

Twenty-three patients continued to have constricted or spiral visual fields at follow-up. Despite persistent evidence of functional visual defects, few patients were either so Forty-two patients with diagnosed functional visual loss were reexamined an average of four years after their initial visit The 191 subjects with NOVL included 102 subjects with a spiral visual field (53%), 6 subjects with tubular tunnel vision (3%), 70 subjects with a normal visual field (37%), and 13 subjects with no data for the visual field. Clinical characteristics, including uncorrected visual acuity (UCVA) and complaints of vision loss, were compared in 125.
Abnormal visual fields were found in 70% of cases and 93% of cases were bilateral spiral visual field. Visual acuity over 20/25 by negative lens method with fogging method is usually found in the cases with normal visual field, while visual acuity under 20/40 by these methods is frequently found in the cases under 10° spiral visual field 1. ไป LGB เป็น visual pathway 2. ผ่าน brachium of superior colliculus ไป superior colliculus (optic tectum) ที่ superficial gray layer คุม Foveal reflex ถ้าเสียจะ disrupts eye movements and alignment 3 (a) Enlarged blind spots (e.g. papilloedema) (b) Left homonymous hemianopia (e.g. stroke) (c) Bitemporal hemianopia (e.g. pituitary tumour) (d) Left central scotoma (e.g. central macular disease) and right upper eyelid artefact (e) Centrocaecal scotomata (e.g. toxic optic neuropathy) and right lens rim artefact (f) Spiral visual fields (the functional or hysterical visual loss associated with.

Augmented amplitude of visually evoked potentials was revealed, and treatment with lomerizine and valproate showed favorable effect on the visual/somesthetic distortion as well as the visual field and acuity. Psychogenic visual problems can co-exist with the typical sensory distortion in AIWS, similarly t Functional visual loss: most commonly presents at age 10-12 years, with girls more frequently affected than boys. It is usually bilateral but can be unilateral. Check vision with neutralizing lenses and look for spiral visual fields. Examine pupils for an afferent pupillary defect of grossly restricted visual fields. Of especial interest is the female teen-ager who occasionally comes to the ophthal-mologist's office complaining of not seeing adequately in school. On testing, a gun-barrel on spiral visual field is obtained. It is interesting that usually, while this girl denies being able to see a small test.

The constricted tubular, spiral or star-shaped visual fields with steep slopes are specific findings in hysteria. We suggest that ophthalmologists should treat patients with psychogenic symptoms, using suggestion, patience and reassurance. Major Subject Heading(s) Minor Subject Heading(s In physics, mathematics and statistics, scale invariance is a feature of objects or laws that do not change if scales of length, energy, or other variables, are multiplied by a common factor, and thus represent a universality.. The technical term for this transformation is a dilatation (also known as dilation), and the dilatations can also form part of a larger conformal symmetry There are many functional complaints in addition to diminished visual acuity. One common complaint is narrowing of the visual field, for which many examiners prefer monocular Tangent Screen visual field testing. In functional disease, the visual field does not expand as would be expected when tested at double the distance with the larger target
