Flammer syndrome. Flammer syndrome is a described clinical entity comprising a complex of clinical features caused mainly by dysregulation of the blood supply. It was previously known as vascular dysregulation. [1] It can manifest in many symptoms, such as cold hands and feet, and is often associated with low blood pressure.
Capillary leak syndrome, or vascular leak syndrome, is characterized by the escape of blood plasma through capillary walls, from the blood circulatory system to surrounding tissues, muscle compartments, organs or body cavities. It is a phenomenon most commonly witnessed in sepsis, and less frequently in autoimmune diseases, differentiation ...
The incidence of eye injuries during general anaesthesia has been studied, and different methods of eye protection have been compared. [citation needed] When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%. [1] [2] If tape is used to hold the eyes closed, ocular injury occurs ...
Ophthalmogram showing blood vessels in front of the retina. Their shadow is the cause of the blue field entoptic phenomenon. The dots are white blood cells moving in the capillaries in front of the retina of the eye. Blue light (optimal wavelength: 430 nm) is absorbed by the red blood cells that fill the capillaries.
Pseudoexfoliation syndrome, often abbreviated as PEX [1] and sometimes as PES or PXS, is an aging-related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. [2] Its cause is unknown, although there is speculation that there may be a genetic basis.
Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [1] [2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] [4] Elevated intraocular pressure is an important risk ...
Marfan syndrome ( MFS) is a multi-systemic genetic disorder that affects the connective tissue. [6] [7] [1] Those with the condition tend to be tall and thin, with long arms, legs, fingers, and toes. [1] They also typically have exceptionally flexible joints and abnormally curved spines. [1]
Eye–hand coordination. Eye–hand coordination (also known as hand–eye coordination) is the coordinated motor control of eye movement with hand movement and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes, a modality of multisensory integration.
