Refers to any inflammation of the sclera including episcleritis, a benign condition affecting only the episclera, which is generally short-lived and easily treated. Classic scleritis, on the other hand, affects deeper tissue and is characterized by higher rates of visual acuity loss and even mortality, particularly in necrotizing form. Its characteristic symptom is severe and general head pain. Scleritis has also been associated with systemic collagen disease. Etiology is unknown but is thought to involve a local immune response. Treatment is difficult and includes administration of anti-inflammatory and immunosuppressive agents such as corticosteroids. Inflammation of the sclera may also be secondary to inflammation of adjacent tissues, such as the conjunctiva.

Orbital dirofilariasis: MR findings. (1/276)

Dirofilariasis is a helminthic zoonosis occurring in many parts of the world. We report the findings in a 61-year-old woman who had painless right exophthalmos caused by orbital dirofilariasis. A vivid worm was embedded inside an inflammatory nodule in the right orbit. On T1-weighted MR images, the parasite was visible as a discrete, low-intensity, tubular signal in the center of the nodule surrounded by contrast-enhancing inflammatory tissue.  (+info)

Significance of serum antibodies reactive with flavoprotein subunit of succinate dehydrogenase in thyroid associated orbitopathy. (2/276)

AIMS: Thyroid associated orbitopathy (TAO) is an autoimmune disorder of extraocular muscles and orbital connective tissue. Identification of the principal target antigens would help the understanding of the pathogenesis of the disease and possibly lead to the development of specific therapies in the future. The purpose of this study was to measure serum antibodies against the flavoprotein subunit of succinate dehydrogenase in patients with TAO and correlate their presence with factors of TAO. METHODS: Sera of patients with active TAO of 6 months' duration or less were tested for antibodies against the flavoprotein subunit of succinate dehydrogenase. Clinical data were obtained by retrospective review of patients' charts. Enzyme linked immunosorbent assay was used to test sera for serum antibodies against purified succinate dehydrogenase. RESULTS: 38 patients with TAO and 32 healthy age and sex matched controls were included in the study. Anti-flavoprotein antibodies were detected in 24 out of 38 patients with TAO (63.16%) and in five out of 32 healthy controls (15.63%) (p<0.01). Neither age, sex, duration of thyroid disease, thyroid status, treatment of thyroid disease, smoking history, duration of orbitopathy, activity of orbitopathy, nor the presence of lid retraction were significantly associated with the presence of serum anti-flavoprotein antibodies (p>0.05). However, the total number of rectus muscles affected in both eyes of the patients was significantly correlated with the finding of a positive antibody test (p<0.05). CONCLUSIONS: Serum antibodies reactive with the flavoprotein subunit of succinate dehydrogenase are associated with extraocular muscle involvement in active TAO of recent onset.  (+info)

Idiopathic sclerotic inflammation of the orbit with left optic nerve compression in a patient with multifocal fibrosclerosis. (3/276)

We present the MR imaging findings in a 43-year-old male patient with bilateral idiopathic sclerosing inflammation of the orbit. Bilateral enhancing retrobulbar masses, with concentric compression of the retrobulbar segment of the left optic nerve, were seen. MR imaging proved to be the only means to distinguish between the different intraorbital structures and to determine the exact site of optic nerve compression. To our knowledge, this is the first documented case of MR imaging findings of this entity.  (+info)

Radiological and clinicopathological features of orbital xanthogranuloma. (4/276)

BACKGROUND: Orbital xanthogranuloma, a diagnosis confirmed histologically, occurs rarely in adults and children. With its characteristic macroscopic appearance the adult form may be associated with a spectrum of biochemical and haematological abnormalities including lymphoproliferative malignancies. METHOD: The clinicopathological features and imaging appearances on computed tomography and magnetic resonance imaging of this condition are described in eight adults and a child. RESULTS: Radiological evidence of proptosis was present in seven patients. In all nine patients an abnormal infiltrative soft tissue mass was seen, with increased fat in six cases. All patients had associated enlargement of extraocular muscles suggestive of infiltration and five had lacrimal gland involvement. Encasement of the optic nerve, bone destruction, and intracranial extension was present only in the child with juvenile xanthogranuloma. Haematological and/or biochemical abnormalities were detected in seven patients and seven patients had other systemic diseases which were considered to have an immune basis. One patient subsequently developed non-Hodgkin's lymphoma. CONCLUSION: The investigation and management of orbital xanthogranulomas requires a multidisciplinary approach even though the diagnosis may be suspected clinically. Imaging delineates the extent of disease and involvement of local structures and may influence the differential diagnosis. The juvenile form may be more locally aggressive, causing bone destruction with consequent intracranial extension.  (+info)

Chronic, traumatic intraconal hematic cyst of the orbit removed through the fronto-orbital approach--case report. (5/276)

A 22-year-old male presented with a chronic encapsulated intraorbital hematoma 3 months after blunt trauma to his left eyeball. Ophthalmological examination found the best corrected visual acuity was 4/20 in the left eye, and 20/20 in the right eye. The orbit exhibited exophthalmus and inability of the eye to move above the horizontal level. Orbital magnetic resonance imaging showed a fairly well-demarcated area in the medial aspect of the orbit appearing as hyperintense on T1-weighted images and isoto hyperintense on T2-weighted images. This area was believed to be hemorrhage. No other abnormalities were found. The diagnosis was hematic cyst. The cyst was approached through a left fronto-orbital route and its location identified within the periorbita and orbital fat. The cyst was removed partially. Histological examination demonstrated cystic accumulation of blood and breakdown products in a non-epithelium-lined fibrous capsule, compatible with hematic cyst. The presence of hemosiderin in the cyst wall suggested that the cyst was a chronically enlarging lesion. Hematic cysts of the orbit usually present as subperiosteal mass months to years after trauma. Surgical removal of the cyst wall rather than needle aspiration is recommended to prevent recurrence.  (+info)

Adipogenesis in thyroid eye disease. (6/276)

PURPOSE: Adipogenesis contributes to the pathogenesis of thyroid eye disease (TED). Thyrotropin receptor (TSHR) transcripts are present in orbital fat. This study was conducted to determine whether they are expressed as functional protein, and if so, whether this is restricted to TED orbits or to a particular stage in adipocyte differentiation. METHODS: Samples of fat were obtained from 18 TED-affected orbits and 4 normal orbits, and 9 were obtained from nonorbital locations. Frozen sections were examined by immunocytochemistry using monoclonal antibodies specific for the human TSHR. Samples were disaggregated and the preadipocytes separated from the mature by differential centrifugation and cultured in serum-free or DM and examined for morphologic changes, oil red O and TSHR staining, and TSH-induced cyclic adenosine monophosphate (cAMP) production. RESULTS: Marked immunoreactivity was observed in frozen sections from all three TED samples and faint staining in both normal orbital fat samples. In vitro, 1% to 5% of preadipocytes displayed TSHR immunoreactivity in five of six TED and two of three normal orbital samples and in three of five nonorbital samples. Differentiation, was induced in all 14 orbital samples. Three of four nonorbital samples contained occasional differentiated cells. Fifty percent to 70% of differentiating cells demonstrated receptor immunoreactivity. Two of three TED and four of four nonorbital preadipocytes in DM and/or mature adipocytes displayed a TSH-mediated increase in cAMP. CONCLUSIONS: The results indicate that orbital fat TSHR transcripts are expressed as protein, which can be functional. This is not aberrant in TED orbits, although expression may be upregulated. The majority of preadipocytes undergoing differentiation express the receptor, indicating a key role for this population in one mechanism for increasing orbital volume.  (+info)

MRI dynamic color mapping: a new quantitative technique for imaging soft tissue motion in the orbit. (7/276)

PURPOSE: To investigate both feasibility and clinical potential of magnetic resonance imaging-dynamic color mapping (MRI-DCM) in measuring the motion of soft tissues in the orbit and in the diagnosis of orbital disorders by detecting changes in motion. METHODS: Sequences of MRI scans were acquired (acquisition time, 5 seconds) in a shoot-stop manner, while the patient fixated at a sequence of 13 gaze positions (8 degrees intervals). Motion was quantified off-line (in millimeters per degree of gaze change) using an optical flow algorithm. The motion was displayed in a color-coded image in which color saturation of a pixel shows the displacement and the hue the displacement's orientation. Six healthy volunteers and four patients (two with an orbital mass and two with acrylic ball implant after enucleation) were studied. RESULTS: The technique was found to be clinically feasible. For a gaze change of 1 degrees, orbital tissues moved between 0.0 and 0.25 mm/deg, depending on the type of tissue and location in the orbit. In the patients with an orbital mass, motion of the mass was similar to that of the medial rectus muscle, suggesting disease of muscular origin. In the enucleated orbits, soft tissue motion was decreased. One eye showed attachment of the optic nerve to the implant, which could be verified by biopsy. CONCLUSIONS: MRI-DCM allows noninvasive and quantitative measurement of soft tissue motion and the changes in motion due to pathologic conditions. In cases in which the diagnosis of a tumor in the apex is in doubt, it may reduce the need for biopsy. In contrast to static computed tomographic (CT) scans and MRIs, it can differentiate between juxtaposition and continuity and may be a new and promising tool in the differential diagnosis of intraorbital lesions.  (+info)

Anaerobic orbital abscess/cellulitis in a Yorkshire Terrier dog. (8/276)

A retrobulbar abscess/cellulitis occurred in a Yorkshire Terrier dog. The clinical signs were exophthalmos, prolapsed nictitating membrane and purulent ocular discharge. Ultrasonography showed a marked soft tissue swelling of the retrobulbar tissues as well as echogenic parallel lines between the globe and the medial orbital rim. Surgical exploration of the orbit was performed and no foreign body was found. The pterygopalatine fossa was incised and therapeutic retrobulbar drainage attempted. A drain was placed to encourage ventral drainage of the abscess. Anaerobic cultures revealed heavy growth of gram negative rods (prevotella bivia and prevotella buccae were isolated). Recovery was successful but subsequent treatment for keratoconjunctivitis sicca was necessary. A full recovery of tear production occurred after several weeks.  (+info)

Purpose: : Angiogenic and growth factors have an important role in directing inflammation and wound healing. At the present time there is limited knowledge of their respective roles in the evolution of pediatric orbital abscesses. Our study aims to characterize the growth and angiogenic factors present within pediatric subperiosteal orbital abscess fluid collections. Methods: : All pediatric cases of subperiosteal orbital abscess drainage performed at a single institution from July 2005 through May 2006 were included in this prospective laboratory study. An external approach was used to drain each fluid collection. In addition to submitting the abscess fluid for routine microbiological analysis, a portion of the abscess fluid was sampled in a sterile fashion and retained for characterization using a cytokine protein membrane array (RayBio Human Cytokine Arrays VI and VII, RayBiotech, Inc., Norcross, GA.) Chemiluminescence was employed to assess for the presence of specific proteins, and those ...
Interesting orbital diseases, besides tumors, include malformations and inflammatory, traumatic, degenerative and dysthyroid diseases, whose incidence depends on factors such as genetic predisposition, sex, race and, especially, age. The two leading diseases in terms of incidence are inflammatory forms and cysts, while dysthyroid orbital disease ranks third, followed by vascular malformations, which rank first for prevalence in adolescents. Traumatisms come fifth, followed by tumors in the sixth place. Until the age of 20, hemangioma is the most frequent orbital disease that alone is the fourth overall cause in terms of incidence. In the 20-60 years of age group the disease is dominated by dysthyroid orbital disease (ca 60% of cases), followed by tumors. In patients aged over 60, dysthyroid orbital disease rank first for incidence, almost at the same level with tumors. Often orbital tumors are rather hard to diagnose as the clinical events triggered by both neoplastic and non-neoplastic diseases ...
Thyroid Eye Disease or Graves Eye Disease is perhaps the most common orbital disease in our population. It is an autoimmune problem, most commonly noted in patient with a history of either high or low thyroid hormones. However, some patients might demonstrate no evidence of thyroid dysfunction. Thyroid Eye Disease can go into periods of remission as well. When it has been inactive for a period of more than 6 months, its less likely to recur.. Thyroid Eye Disease can be divided in stages. During the early part of the disease, the eyes become red, swollen, and watery. This early part of the disease is referred to as the active and inflammatory phase of the disease. During this initial phase of the disease, patients may benefit from treatments to reduce inflammation such as anti-inflammatory medications or injections, topical lubricating eye drops and ointments, and in some cases, referral for orbital radiation. In the later part of the disease the eyes may bulge out of the socket, the eyelids ...

Because of the relatively low complication rate from endoscopic surgery of the paranasal sinuses, orbital injury only occasionally presents to the ophthalmologist. These orbital complications include injury to the nasolacrimal duct, orbital emphysema, diplopia, orbital haematoma, and temporary or permanent blindness.2 The most devastating complication is blindness resulting from optic nerve compression by haematoma or direct injury to the nerve itself. If injury of the anterior ethmoidal artery occurs during the ethmoidectomy, it may be difficult to control the bleeding owing to the contraction of the vessel into the orbit.. The pathogenesis of subperiosteal orbital haematoma is (1) traumatic tearing of an orbital vessel, (2) rupture of a subperiosteal vessel secondary to increased venous pressure transmitted by valveless orbital veins from congested sinus mucosa, or (3) erosion of a vessel by orbital extension of an infectious process. Its frequent occurrence in the roof of the orbit may be ...

A look at periorbital edema, a condition where swelling around the eyes causes them to appear puffy. Included is detail on diagnosis and the outlook.
Orbital subperiosteal hemorrhage (SpH) is a rare cause of spontaneous proptosis, which results most commonly from direct trauma but also from increased central vascular congestion following valsalva, weightlifting, emesis, or scuba diving.(1-4) Additionally, SpH may result from periorbital inflammation (eg, sinusitis, orbital cellulitis, endophthalmitis), underlying metabolic disorders, vascular disorders, orbital infarction, migraines, or idiopathically.(5-8) Although most resolve without long-term visual or orbital sequelae, some SpHs may cause profound visual loss as well as orbital changes. Acute hematomas can resolve spontaneously or develop into subacute and chronic hematomas (hematic cysts of the orbit). In this light, SpH shares features with epidural hematomas of the central nervous system. The literature on acute SpH consists of isolated cases reports underscoring the rarity of the condition.(8) Because many reports of orbital hemorrhage do not differentiate between intraconal, ...

The diagnosis is of a subperiosteal hematoma, due to the strain of the iliac muscle. The patients thigh pain can be secondary to nerve compression.
Orbital lesions form a wide range of pathologies that pose challenges in diagnosis, management and treatment. The soft tissue detail provided by magnetic resonance imaging (MRI) allows for better lesion characterization. MRI therefore plays a crucial role, especially in cases where history and clinical evaluation are inconclusive [1]. There are several approaches for the correct diagnosis of orbital pathology. A common diagnostic strategy is the localization of the pathology into the four main orbital compartments [2]: the ocular compartment or globe, the muscle cone and the intraconal and extraconal spaces (Figure 1). The muscle cone contains recti muscles and their fasciae; on its base, the globe is present, and the optic canal figures the apex. The globe is encircled by the Tenons capsule, which has three layers: the sclera, uvea and retina. The extraconal space includes the superior and inferior oblique muscles, levator muscle complex, the lacrimal gland and the orbital fat. The aim of this ...

I have always been interested in infectious disease (ID), and I am known as the bug guy in my class. Its an odd choice, and I am one of the few that I have met in my class with a true passion for ID. I admit that it seems a bit alienating at times, but the cases I have seen with my ID mentors have been some of the most interesting I have experienced, and the following case is one of my favorites.. The patient was a 43-year-old man with a past medical history significant for hypertension and diabetes. He presented to the emergency department with a very simple complaint: I blew out my eye. Upon physical examination there was severe erythema of the right eye with periorbital swelling and marked proptosis. It was one of those cases where you look at the patient and you say, I may not know much, but I know that is not good. The patients extraocular muscle movements were not ...

Only 2 of the 2p orbitals are used in sp2 hybridisation; in contrast to the 3 used in sp3 hybridisation (you should be seeing where the numbers come from!).. This leaves us with 3 sp3-orbitals and 1 p-orbital to bond with. 2 of the sp3 orbitals are used for forming σ-bonds with the 2 hydrogens, while the remaining sp3 orbital binds with the other carbon to form a σ-bond and the p-orbital bonds with a p-orbital from the other carbon to form a π-bond.. Every double bond (regardless of what atoms it joins) consists of a π-bond and a σ-bond.. ...

None of what youve learned so far is wrong. However, your understanding of bonding in covalent compounds isnt yet complete. Specifically, while we know that electrons are shared between two atoms in a covalent molecule, we dont have any ideas about the locations of these electrons. As you might imagine, theyre located within orbitals, but what sort of orbitals exist between two atoms?. Why are orbitals important? As it turns out, covalent bonds are formed when two orbitals from different atoms, each of which have one electron in them, overlap so that these two electrons are shared. Because these orbitals need to overlap for a bond to be formed, its important that we understand the shapes of orbitals that are formed in covalent compounds.. Before we can fully understand the true nature of orbitals in covalent compounds, we must see whats incomplete about our current understanding of orbitals and electrons. Imagine CH4. The type of diagram we saw in Getting to Know Covalent Compounds makes ...

Cavernous sinus thrombosis (CST) is mainly ascribed to infection of the sphenoid and ethmoid sinuses. The infection may spread due to retrograde thrombophlebitis involving the ophthalmic vein or direct extension. Initially, the patient may suffer from periorbital edema, diplopia, photophobia, headache and fever.. Inflammatory edema is also called preseptal or periorbital cellulite. Eyelids swell near the orbital septum, but the orbits soft tissues are not affected. The septum prevents infection from spreading into the orbit. If extra ocular movement stops, soft tissues are also affected.. Orbital abscess means pus accumulation within the tissue of the orbit. This complication may lead to proptosis, which means forward displacement or projection of the eyeball, and loss of vision. The abscess may also limit the extra ocular movement.. Orbital cellulite implies inflammation and edema of the orbit area, but there is no abscess. Partial or complete paralysis of eye muscles (ophthalmoplegia), ...

Periorbital puffiness, also known as puffy eyes, or swelling around the eyes, is the appearance of swelling in the tissues around the eyes, called the orbits. It is almost exclusively caused by fluid buildup around the eyes, or periorbital edema. Minor puffiness usually detectable below the eyes only (although at times they could be present all around) is often called eye bags. Such transient puffiness is distinct from the age related and gradual increase in the size of the fat pad lying below the lower eyelids (suborbicularis oculi fat - SOOF) which can also be colloquially referred to as eye bags. While some degree of puffiness may be normal for a given individual, factors such as age and fatigue may make the swelling more prominent. The periorbital tissues are most noticeably swollen immediately after waking, perhaps due to the gravitational redistribution of fluid in the horizontal position. Eye puffiness may also be caused by: Mononucleosis - With supra-orbital oedema, the eyes become ...

I once had the same question as you and I did go to my chemistry teacher for an answer. This is his original response:. In hydrogen, all orbitals with the same principal quantum number n (1,2,3...) are degenerate, regardless of the orbital angular momentum quantum number l (0,1...n-1 or s,p,d,). However, in atoms with more than one electron, orbitals with different values of l for a given value for n are not degenerate. Why is this? Surely the radial distribution functions are similar for hydrogen (in that theres still penetration of orbitals and so on). Or is it that orbitals with different values of l are degenerate for a value of n greater than would be occupied in that particular atoms ground state?. The answer is right there in your question. Its only the interaction of multiple electrons in an atom like He, Li, Be, etc. that makes the different angular momenta wave functions differ in energy. Consider this. For the one electron system, why should a p or d orbital differ in energy ...

TY - JOUR. T1 - Deviation of stellar orbits from test particle trajectories around SGr A* due to tides and winds. AU - Psaltis, Dimitrios. AU - Li, Gongjie. AU - Loeb, Abraham. PY - 2013/11/1. Y1 - 2013/11/1. N2 - Monitoring the orbits of stars around Sgr A* offers the possibility of detecting the precession of their orbital planes due to frame dragging, of measuring the spin and quadrupole moment of the black hole, and of testing the no-hair theorem. Here we investigate whether the deviations of stellar orbits from test-particle trajectories due to wind mass loss and tidal dissipation of the orbital energy compromise such measurements. We find that the effects of stellar winds are, in general, negligible. On the other hand, for the most eccentric orbits (e , 0.96) for which an optical interferometer, such as GRAVITY, will detect orbital plane precession due to frame dragging, the tidal dissipation of orbital energy occurs at timescales comparable to the timescale of precession due to the ...
Question 1: B. The element must be from Group IV so the electronic configuration must be either 1s22s22p2 or 1s22s22p63s23p2. The four electrons of highest energy refer to the electrons at shells with higher principal quantum number. The best answer is B.. Question 2: B. Sigma bonds can be formed via head-on overlap between two s orbitals, two p orbitals and between one s and one p orbitals. In hydrocarbons, the carbon atoms have hybrid orbitals consisting of s and p orbitals. Hence, sigma bonds can be formed by either s or p orbitals while the pi bonds can only be formed by side-way overlap between two p orbitals.. Question 3: C. Oxygen atom has 8 electrons. Hydrogen atom has 1 electron. Since hydroxide anion has an extra electron gained, the total number of electrons is 10. Oxygen atom has 8 neutrons while hydrogen atom has no neutrons. Hence, the answer is C.. Question 4: C. A higher charge on Ca2+ would mean that the electrostatic forces of attraction between the cation and the sea of mobile ...
The ability to perform an inclination change maximizes the maneuverability of an orbiting space vehicle. Most maneuvers utilize a combined plane change and orbital transfer to the new orbit. This costs more in terms of energy and fuel than an in-plane change of orbits. The amount of DV and fuel required for such an energyintensive inclination change exceeds the benefit of performing the maneuver. However, this paper demonstrates that a winged re-entry vehicle, based on the currently proposed X-37, has the necessary thrust to change planes and then perform an in-plane transfer to achieve a new orbit. Using SIMULINKâ and LABVIEWâ simulation tools, this research found that the use of the aerodynamic lift of a winged re-entry vehicle produced more than 12Ê» of inclination change with the minimal DV achievable. Through small orbital maneuvers and atmospheric reentry, the aerodynamics of the lift vector demonstrated that the spacecraft retained sufficient energy to prevent perigee collapse using ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The problem of many revolution low-thrust Earth-orbit trajectory optimization is considered. The objective is to transfer a spacecraft from a parking orbit to a de-sired terminal orbit in minimum time. The minimum-time orbital transfer problem is posed as a nonlinear optimal control problem, and the optimal control problem is solved using a direct transcription variable-order Gaussian quadrature collocation method. It is found that the thrust-to-mass ratio holds a power relationship to the transfer time, final mass, and final true longitude. Using these power relationships obtained through regression on the collected results, it is possible to estimate the performance of a given thrust-to-mass ratio without solving for the optimal trajec-tory. In addition, the key structure of the optimal orbital transfers are identified. The results presented provide insight into the structure of the optimal performance for a range of small
For the restricted three-body problem, we propose an accurate orbital integration scheme that retains all conserved quantities of the two-body problem with two primaries and approximately preserves the Jacobi integral. The scheme is obtained by taking the limit as mass approaches zero in the discrete-time general three-body problem. For a long time interval, the proposed scheme precisely reproduces various periodic orbits that cannot be accurately computed by other generic integrators. ...
