Upon closer inspection, the woman found another worm in her eye, which she was also able to remove by hand after rinsing her eyeball with. Amazingly, with a few tweaks to the tissue's environment. In order to better understand the way nerve cells succumb to a lack of oxygen, a team of US researchers measured activity in mouse and human retinal cells soon after their death. It's constantly blinking, and the eyelids dynamically adapt to the eyeball movements-it's even got human hairs implanted for the eyebrows and eyelashes. A 68-year-old woman returned from a trail run on the California coast only to discover the culprit of the itching sensation in her right eye was a half-inch long worm she proceeded to pull out of her eyeball. Scientists have momentarily restored a faint twinkle of life to dying cells in the human eye. The Eyecam can function autonomously and react to external stimuli, such as the presence of users. The device consists of six servo-motors controlled by an Arduino Nano that reproduce different eye muscles, while the camera itself (720p60) is connected to a Raspberry Pi Zero and works as a standard plug & play webcam. Its disappointing gaze burning into you from atop a monitor could certainly put people off visiting Pornhub, for example. It's an interesting project: it's easy to imagine that most people would behave differently if they had a human eyeball staring at them instead of a webcam's cold lens, especially as it can blink and express emotion. The anthropomorphic webcam is designed to "challenge conventional relationships with ubiquitous sensing devices and call to re-think how sensing devices might appear and behave." The aptly named Eyecam comes from researcher Marc Teyssier and is part of research at the Saarland University Human-Computer Interaction Lab. 5–6.WTF?! Have you ever looked at your webcam and thought, "yeah, it performs its intended functions, but I wish the camera resembled a disembodied human eye-like something from a David Cronenberg movie." If so, here's some good news: your disturbing fantasy has been made real. Why the eye is round? In: Fischbarg J., editor. Intracranial pressure monitoring: Invasive versus non-invasive methods-a review. Investigative Ophthalmology and Visual Science. The association between retinal vessel diameter and retinal nerve fiber layer thickness in asymmetric normal tension glaucoma patients. Measurement of optic nerve head parameters: comparison of optical coherence tomography with digital planimetry. Automated diagnosis of glaucoma using digital fundus images. These data might be useful in ophthalmological, oculoplastic, and neurological practice. In the transverse diameter, the eyeball size may vary from 21 mm to 27 mm. The size of a human adult eye is approximately 24.2 mm (transverse) × 23.7 mm (sagittal) × 22.0-24.8 mm (axial) with no significant difference between sexes and age groups. Strong correlation was found between the transverse diameter and the width of the orbit (r = 0.88). The protrusion of the eyeballsproptosisin exophthalmic goitre is caused by the collection of fluid in the orbital fatty tissue. We did not find statistically significant differences of the eyeball sizes among the ethnicities we dealt with. The eyeball and its functional muscles are surrounded by a layer of orbital fat that acts much like a cushion, permitting a smooth rotation of the eyeball about a virtually fixed point, the centre of rotation. The right eyeball was slightly smaller than the left one but this difference was statistically insignificant (P = 0.17). We did not find statistically significant differences correlated with gender of the patients and their age. The correlation analysis was performed with the following variables: orbit size, gender, age, and ethnic background. The data obtained from the left eye and from the right eye were compared. In a prospective cohort study, the CT data of consecutive 250 adults with healthy eyes were collected and analyzed, and sagittal, transverse, and axial diameters of both eyeballs were measured. The purpose of the current research was to reevaluate the normative data on the eyeball diameters.
