Common symptoms include decreased vision and uveitis.Orbital apex syndrome: Orbital apex syndrome, also known as Jacod syndrome, is a collection of cranial nerve deficits associated with a mass lesion near the apex of the orbit of the eye. This syndrome is a separate entity from Rochon–Duvigneaud syndrome, which occurs due to a lesion immediately anterior to the orbital apex.ExophthalmosInferior rectus muscle: The inferior rectus muscle is a muscle in the orbit.Infiltrative ophthalmopathy: Infiltrative ophthalmopathy is found in Graves disease and resembles exophthalmos, except that the blurry or double vision is acquired because of weakness in the ocular muscles of the eye.

From this nucleus the fibers pass forward through the tegmentum, the red nucleus, and the medial part of the substantia nigra, forming a series of curves with a lateral convexity, and emerge from the oculomotor sulcus on the medial side of the cerebral peduncle.Robotic spacecraft: 250px|right|thumb|An artist's interpretation of the [[MESSENGER spacecraft at Mercury]]Explosive material: An explosive material, also called an explosive, is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material.Cavernous hemangioma: Cavernous hemangioma, also called cavernous angioma, or cavernoma (often when referring to presence in the brain), is a type of blood vessel malformation or hemangioma, where a collection of dilated blood vessels form a tumor. Because of this malformation, blood flow through the cavities, or caverns, is slow.Cranial vault: The cranial vault is the space in the skull within the neurocranium, occupied by the brain. In humans, the size and shape of the brain, may be affected by the size of the vault as shown in craniometry, but studies relating it to intelligence have found no conclusive evidence.Hay–Wells syndromeConjunctivochalasisMucocele: A mucocele is any dilatation (typically pathologic) with accumulation of mucus.

These tumors are typically a benign; they can grow, but rarely transform into a malignancy.Neuro-ophthalmology: Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field.Interstellar cloud: Interstellar cloud is the generic name given to an accumulation of gas, plasma, and dust in our and other galaxies. Put differently, an interstellar cloud is a denser-than-average region of the interstellar medium.Paranasal sinuses: Sinus}}OphthalmoparesisOrbital cellulitisSubmillimetre astronomy: Submillimetre astronomy or submillimeter astronomy (see spelling differences) is the branch of observational astronomy that is conducted at submillimetre wavelengths (i.e.Ganymede (moon)DacryoadenitisUltra-high-energy cosmic ray: In astroparticle physics, an ultra-high-energy cosmic ray (UHECR) is a cosmic ray particle with a kinetic energy greater than eV, far beyond both its rest mass and energies typical of other cosmic ray particles.Saturn A-1: Saturn A-1, studied in 1959, was projected to be the first version of Saturn I and was to be used if necessary before the S-IV liquid hydrogen second stage became available. The first stage, proposed for the Juno V rocket, but finally used for the first Saturn rocket, would propel the Saturn A-1 into space, with the first stage of a Titan I missile continuing the flight and finally, a Centaur C high-energy double-engine third stage could perform a small burn to send a payload into its final orbit, or it can perform a big burn to take a payload out of Earth orbit to other planets.Micro-g environment: The term micro-g environment (also µg, often referred to by the term microgravity) is more or less a synonym of weightlessness and zero-G, but indicates that g-forces are not quite zero, just very small. The symbol for microgravity, µg, was used on the insignias of Space Shuttle flights STS-87 and STS-107, because these flights were devoted to microgravity research in low Earth orbit.Codman triangle: Codman triangle (previously referred to as Codman's triangle) is the triangular area of new subperiosteal bone that is created when a lesion, often a tumour, raises the periosteum away from the bone.General Practice notebook A Codman triangle is not actually a full triangle.Fibrocartilaginous mesenchymoma of boneDevil facial tumour diseaseMarcus Gunn phenomenonSymptoms and signs of Graves' disease: Virtually all the symptoms and signs of Graves' disease result from the direct and indirect effects of hyperthyroidism, with exceptions being Graves' ophthalmopathy, goitre and pretibial myxedema (which are caused by the autoimmune processes of Graves' disease). These clinical manifestations are dramatic and involve virtually every system in the body.Diffuse unilateral subacute neuroretinitis: Diffuse unilateral subacute neuroretinitis (DUSN) is a rare condition that occurs in otherwise healthy, often young patients and is due to the presence of a subretinal nematode.StrabismusNebulaOctave Crouzon: Octave Crouzon, full name Louis Edouard Octave Crouzon (1874–1938) was a French neurologist born in Paris.TrinitrotolueneArterial resistivity index: The arterial resistivity index (also called as Resistance index, abbreviated as RI), developed by Leandre Pourcelot, is a measure of pulsatile blood flow that reflects the resistance to blood flow caused by microvascular bed distal to the site of measurement.Dense connective tissue: Dense connective tissue, also called dense fibrous tissue, has fibers as its main matrix element.Median mandibular cyst: A median mandibular cyst is a type of cyst that occurs in the midline of the mandible, thought to be created by proliferation and cystic degeneration of resting epithelial tissue that is left trapped within the substance of the bone during embryologic fusion of the two halves of the mandible, along the plane of fusion later termed the symphysis menti. A ture median mandibular cyst would therefore be classified as a non-odontogenic, fissural cyst.Bifrontal craniotomy: a bifrontal craniotomy is a surgical process which is used to target different tumors or malfunctioning areas of the brain.http://www.Primordial soup: "Primordial soup" is a term introduced by the Soviet biologist Alexander Oparin.

Evidence for the magma ocean hypothesis comes from the highly anorthositic compositions of the crust in the lunar highlands, as well as the existence of rocks with a high concentration of the geochemical component referred to as KREEP.BlepharochalasisSinonasal undifferentiated carcinoma: Sinonasal undifferentiated carcinoma, abbreviated SNUC, is a rare aggressive type of cancer that arises from epithelium or lining of the nose or sinuses.EsotropiaList of Antarctic ice streams: This is a list of Antarctic ice streams.Conjugate gaze palsyHarderian gland: The Harderian gland is a gland found within the eye's orbit which occurs in tetrapods (reptiles, amphibians, birds and mammals) that possess a nictitating membrane.Protein quaternary structure: In biochemistry, quaternary structure is the number and arrangement of multiple folded protein subunits in a multi-subunit complex.
