- Visual Mass is an alternative optometry/eyewear brand with a mission to provide sight for the masses without the clutch of unreasonable pricing. Having grown from a tiny kiosk to a proper brick and mortar store, we were tasked to give the brand a whole new identity.

Visual Field Testing Visual field testing is a sophisticated, automated computerized vision test that measures both central and peripheral vision/visual function. It is essential in monitoring glaucoma and it is a useful ancillary test to diagnose, document or treat neurologic or retinal disease.

Design Principles: Compositional, Symmetrical And Asymmetrical Balance As a reminder, below are definitions for visual weight and visual direction, although I’ll refer you back to the fourth post in this series for more details. 1  visual weight. This is the perceived weight of a visual element. 2  visual direction. This is the perceived direction of a visual force.

- The visual weight of an image. Balance can relate to symmetry, asymmetry or radial balance. 1  Symmetrical Balance is an even placement of visual weight in the design. 2  Asymmetrical Balance creates uneven spaces, a sense of imbalance making tension and a dynamic suggestion of visual movement.

Visual field test The visual field test produces a computer printout of the light thresholds that the patient’s eyes were able to perceive and process (Fig. 2). The darkest areas of the test indicate a complete loss of vision in that area. The lighter the area, the more vision the patient has in that part of the eye.Figure 2. Visual field test of a patient with a meningioma shows vision loss (black areas) in half of the right eye, called hemaniopia.Visual field loss, also known as “visual field cut,” can be partial or complete.he lighter the area, the more vision the patient has in that part of the eye.

Amaurosis fugax The experience of amaurosis fugax is classically described as a transient monocular or binocular vision loss that appears as a black curtain coming down vertically into the field of vision in one eye; however, this altitudinal visual loss is relatively uncommon.

Visual Migraine A visual migraine is a temporary visual distortion that often begins with a small sparkling, shimmering area that slowly expands outward. The growing spot often has jagged, zig-zag edges. The visual symptoms typically last approximately 20-30 minutes and then completely resolve.

- Superior oblique myokymia (SOM) is a neurologic disorder that affects vision. It is a problem concerning the fourth cranial nerve and its relationship to the superior oblique muscle. Superior oblique myokymia is a condition that presents as repeated, brief episodes of movement, shimmering or shaking of the vision of one eye, a feeling of the eye trembling, or vertical/tilted double vision. It can present as one or more of these symptoms.

VisionBlue Staining Solution from Dutch Ophthalmic, USA Visionblue® is a staining solution for cataract surgery. A complete capsulorhexis is required for performing a safe phaco-emulsification procedure. Inadequate visualization of the anterior lens capsule may result in an incomplete capsulorhexis, which carries a high risk of radial capsule tears and associated complications.

2. Central Nervous System MR images show well-defined, round mass that corresponds to mammographic and sonographic findings. Mass shows characteristics of proteinaceous or hemorrhagic cyst, with low signal on T1-weighted image (E), high signal on unenhanced T2-weighted image (F), and minimal rim enhancement on subtracted image (G).

Cerebral Intraventricular Neoplasms: Radiologic-Pathologic Correlation1 On MR images, choroid plexus papillomas appear as isointense to hypointense intraventricular masses compared with normal brain parenchyma with short TR pulse sequences and variable signal intensity masses with long TR pulse sequences (80,96). Flow voids, consistent with flowing blood, are common (Figs 20, 21) (80).

Composition, Balance and Visual Mass The mountains have more visual mass than the sky, therefore the photo benefits from having more sky in it. The telegraph pole in the bottom right third is the focal point of the image. It has a lot of visual mass, assisted by its placement on the thirds. The visual mass of the telegraph pole is so strong that even at this small size it is balanced by the rest of the image. Finally, an image with a composition that at first glance seems to be at odds with what I said earlier about tonal balance:

Top 8 Misconceptions about Cortical Visual Impairment (CVI) Unfortunately, this is too often the case for families of children with Cortical Visual Impairment (CVI), also referred to as Cerebral Visual Impairment or Neurological Visual Impairment. Cortical Visual Impairment is a visual impairment caused by the brain’s inability to correctly process what is in front of the eye rather than a physical difference of the eye as in other visual impairments.

Glaucoma Service Foundation Web Blog Dr. Elliot Werner: The visual field is measured by shining little dots of light (stimuli) on a screen or bowl and asking patients if they see them. It is not painful, but it is tedious and boring. A visual field test takes, on average, about 10 to 12 minutes per eye.

- Marianna Crowley, MD. Postoperative visual loss (POVL) is a rare complication of surgery, with increased prevalence after cardiac, spine, head and neck, and some orthopedic procedures. The most common cause of postoperative ocular injury is corneal abrasion, which may or may not be associated with visual loss. The most common causes of permanent POVL are central retinal artery occlusion, ischemic optic neuropathy, and cerebral vision loss.

What Is the Optic Chiasm and How Does it Affect Vision? The optic chiasm is an X-shaped structure formed by the crossing of the optic nerves in the brain. The optic nerve connects the brain to the eye. At the optic chiasm, nerve fibers from half of each retina cross over to the opposite side of the brain. The fibers from the other half of the retina travel to the same side of the brain. Because of this junction, each half of the brain receives visual signals from the visual fields of both eyes.

Continuing education program: focusâ¦Imaging of the optic chiasm and retrochiasmal visual pathways A bitemporal hemianopsis suggests a lesion of the optic chiasm while homonymous lateral hemianopsis should lead to a search for a lesion of the retrochiasmal visual pathways. The causes of chiasmal impairment are mainly tumoral.

- Compression by the internal carotid arteries can injure the lateral fibers on each side of the optic chiasma. An MRI may be used to diagnose a tumor in the chiasma area. Damage to the optic chiasma can cause impaired vision. Those with tumors in the chiasmal area may have headaches and vision problems.

- Videonystagmography (VNG) Your physician has asked you to have a VNG test. This is a test of your balance or vestibular system. Your eye movements are the objective measure of dizziness, vertigo or imbalance. The test is performed with goggles that have infra-red cameras inside and magnify and record your eye movements during the test.
