TY - JOUR. T1 - Human orbital tissue and thyroid membranes express a 64 kDa protein which is recognized by autoantibodies in the serum of patients with thyroid-associated ophthalmopathy. AU - Salvi, M.. AU - Miller, A.. AU - Wall, J. R.. PY - 1988/5/9. Y1 - 1988/5/9. N2 - A 64 kDa protein has been identified in the membrane fraction of human eye muscle, orbital connective tissue and thyroid, by testing sera of patients with thyroid-associated ophthalmopathy in SDS-polyacrylamide gel electrophoresis and Western blotting. Antibodies to this membrane antigen seem characteristic of the early stage of ophthalmopathy. In the thyroid this newly recognized protein seems different from previously known membrane antigens. A thyroid antibody reactive with a 64 kDa membrane antigen in eye muscle could explain the very frequent association of ophthalmopathy with autoimmune thyroid disease.. AB - A 64 kDa protein has been identified in the membrane fraction of human eye muscle, orbital connective tissue and ...
TY - JOUR. T1 - Orbitocranial wooden foreign body diagnosed by magnetic resonance imaging. Dry wood can be isodense with air and orbital fat by computed tomography. AU - Specht, Charles S.. AU - Varga, John H.. AU - Jalali, Michael M.. AU - Edelstein, Jeffrey P.. PY - 1992/1/1. Y1 - 1992/1/1. N2 - In computed tomographic (CT) scans, a wooden foreign body can appear as a lucency with nearly the same density as air or fat, and it can be indistinguishable from orbital adipose tissue. Magnetic resonance imaging (MRI) can localize these wooden foreign bodies in the orbit. We studied a case in which a wooden golf tee lodged in the right optic canal of a nine-year-old boy. The head portion lodged in the orbital apex and the tip entered the interpeduncular fossa. Clinical examination revealed a right paranasal laceration; the right eye had no light perception and a peripapillary hemorrhage, but was otherwise normal. Surgical exploration and evaluation by CT failed to locate the foreign body. However, ...
Orbital injury and complications are commonly encountered in endoscopic sinus surgery (ESS) despite advances in techniques and instrumentation. For the recent 10 years, we summarized the experience of the rhinology unit of our department regarding orbital injury and complications of ESS for sinonasal inflammatory disorders. One thousand seventy-three patients (1869 sides) from January 1, 2003 to December 31, 2012 undergoing ESS for sinonasal inflammatory diseases were enrolled in the present study. The age of the patients ranged from 8 to 81 years, mean age 49 years. Orbital injury and complications were observed in 13 patients (13 sides), which corresponded to 0.7% of the operated sides and 1.2% of the patients. Eight patients showed herniation of orbital fat alone through the injury of the lamina papyracea. The protruding orbital fat was snipped and cut using forceps in 2 patients. Removal of exposed orbital fat using powered instruments was performed in 3 patients, two of whom transiently showed

N2 - PURPOSE: The objectives of this study were measure the orbital volume of healthy Koreans and analyze the differences between orbital tissue volume with respect to age and sex and to assess any correlation between body mass index (BMI), eyeball position, and orbital volume. METHODS: We retrospectively evaluated the scan results of patients who had undergone orbital computed tomography scans between November 2010 and November 2011. We assessed the scan results of 184 orbits in 92 adults who had no pathology of the orbit. The individuals were classified into 3 groups with respect to age. Orbital volume, effective orbital volume (defined as the difference between orbital and eyeball volume), extraocular muscle volume, ...
A decision was made for a left transcranial orbitotomy with a cranio-orbital approach for removal of the foreign body. The posterior location of the pellet in the orbital apex eliminated an anterior orbitotomy approach. A lateral approach could have been used yet it would have required an osteotomy extending along the lateral orbital wall that was posteriorly fragmented. This would have required enlarging the bony incision of a classic lateral orbitotomy and removing the sphenoid wing to the superior orbital fissure, as described by Goldberg et al.(5) This approach would have eliminated the need for a craniotomy; however, it was possible that this might not have provided enough access and exposure to safely extract the pellet. A multidisciplinary team included our neurosurgery service who performed a left transcranial orbitotomy with a cranio-orbital approach and provided access for our oculoplastic surgery team. A cranio-orbital approach allowed for direct visualization of the superior orbital ...

Purpose: : Thyroid Eye Dsease is characterized by infiltration of white blood cells and accumulation of nonsulfated glycosaminoglycan hyaluronan (HA) in orbital tissue. The inflamed orbital tissue can become full of scar and fat tissue. Transforming growth factor beta (TGFβ) acts as a key inducer of the fibrotic response by enhancing extracellular matrix production. Peroxisome proliferator-activated receptor gamma (PPARγ) ligands have anti-inflammatory and antifibrotic activities. In this study, we hypothesized that TGFβ would induce HA synthesis/secretion and that PPARγ ligands would inhibit this response in orbital fibroblasts. Methods: : Primary orbital fibroblasts were isolated from individual Graves patients undergoing orbital decompression surgery. The cells were grown in RPMI media containing 10%FBS. The amount of HA in the cell culture supernatant was measured by ELISA. HA synthase (HAS) mRNA expression was analyzed by real-time RT-PCR. Results: : Treatment of human orbital ...
TY - JOUR. T1 - Orbital Trauma Caused by Bicycle Hand Brakes. AU - Ng, John. AU - Payner, Troy D.. AU - Holck, David E E. AU - Martin, Ronald T.. AU - Nunery, William T.. PY - 2004/1. Y1 - 2004/1. N2 - Purpose: This report aims to increase awareness of an unusual mechanism of orbital injury sustained by bicycle riders. Methods: In this retrospective small case series, we describe two cases of orbital injury caused by upper eyelid penetration. A 5-year-old boy (patient 1) and a 6-year-old boy (patient 2) presented to our service within a 2-week period. Both had been injured by similarly styled, handlebar-mounted bicycle hand brake levers. Patient 1 had an orbital roof fracture and penetrating brain injury and underwent repair of a left upper eyelid laceration, craniotomy for pseudoencephalocele, and ptosis repair. Patient 2 had orbital hemorrhage and underwent repair of left upper eyelid laceration. Results: In both cases, a handlebar-mounted bicycle hand brake lever perforated the left eyelid ...
Results Mean logarithm of the minimum angle of resolution (logMAR) VA increased, statistically significantly, by 2.4 lines during 30±13 months (from 0.38±0.25 before surgery to 0.14±0.1 at the end of observation, p=0.0001). All eyes maintained or improved vision by at least one line. Mean postoperative reduction of proptosis was 6.4±3 mm. While VECP P100 amplitudes improved significantly, P100 latencies remained abnormal in 18 eyes (60%) during follow-up of 10±7 months. Nine eyes (30%) with previous latency defects improved in at least one check test, five of which normalised completely. Worsening was evident in seven eyes (23%), and three previously normal eyes developed new pathological latencies. P100 latencies in 14 eyes (47%) remained unchanged. ...

Definition : Ophthalmic implants designed for the total or partial reconstruction and/or augmentation of the extraocular rim, including the inferior (i.e., orbital floor), lateral (i.e., orbital wall), and superior parts of the rim. These implants are manufactured in a variety of sizes and shapes according to the intended use; they are typically made of high-density polymers (e.g., polyethylene) that are frequently reinforced with an embedded metal (usually titanium) mesh. The implants can be trimmed to fit the patients orbital anatomy. Dedicated orbital rim implants are available for use in procedures such as reconstruction of the orbital floor and wall augmentation of the inferior and lateral rim, augmentation of the lateral and superior or orbital rims in patients who are hypoplasic, and to support the lower eyelid and lateral canthus in patients who have inadequate support. These implants are used mainly to repair traumatic damage (e.g., fractures), to improve the function of the eyes, or ...
In a finite element analysis of orbital tissue mechanics, Schutte et al. 29 estimated the elastic modulus, which is equivalent to long-term stiffness in the present study, for intraconal and extraconal retrobulbar fat to be 0.3 and 1.0 KPa, respectively. Although "muscle cone" as a demarcating structure in the deep orbit is an anatomic fiction, 30 the bovine orbital fatty tissue in current investigation may correspond to what Schutte et al. 29 termed intraconal retrobulbar fat. The present study determined the long-term stiffness of human orbital fat to be 0.71 KPa, which is of similar magnitude to that reported by Schutte et al. 29 A more important observation of the current investigation, however, was similarity in the stiffness of normal human and bovine orbital fatty tissue. As can be seen in Table 1, the long-term stiffness of human orbital fatty tissue and bovine orbital fatty tissue are similar at 0.74 and 0.71 KPa, respectively. Although there is ,5% difference in long-term stiffness ...

And then something kinda slowly happened. After all, you do get brainwashed training at the same institution for six years. And not that I consider myself a brilliant researcher, but at least I learnt some of the ropes. I learnt what it takes to write a paper, analyze a study, even perform experiments (I got to play with human orbital fibroblasts, yay!). And I popped my publication cherry. And became a scientist. I still consider myself one- after all, a doctor is a person of science, and as dynamic as science can be, we too need to evolve and learn, dont we? And so, its interesting how I went from that hater of EBM in 1999, to one who looks at The Evidence, to guide his clinical judgments. Not only the conclusions of the study, but also to try to pick apart the study to see if he agrees with the findings. After all, the goal of an author is to get the study published, and one often learns to present the data in the most compelling way; so you cant always take things at face value. And so, ...

Scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin combined state-of-the-art experiments and numerical simulations to test a fundamental assumption underlying strong-field physics. Their results refine our understanding of strong-field processes such as high harmonic generation (HHG) and laser-induced electron diffraction (LIED). Strong infrared laser pulses can extract an electron from a molecule (ionization), accelerate it away into free space, then turn it around (propagation), and finally collide it with the molecule (recollision). This is the widely used three-step model of strong-field physics. In the recollision step, the electron may, for example, recombine with the parent ion, giving rise to high harmonic generation, or scatter elastically, giving rise to laser-induced electron diffraction. One of the commonly used assumptions underlying attosecond physics is that, in the propagation step, the initial structure of the ionized electron is
There is no difference between the sexes when it comes to an exaggerated temporal fossa depression. Even though I have treated only one woman with a significant indentation, I believe strongly that a deeply concave or inwardly curved space has nothing to do with gender. Whether you are a man or a woman, a pronounced hollow just behind your lateral orbital rims, the bony ridges to the side of your eyes, can have a significant effect on your facial aesthetics. This hollow can make you appear starving when you are well fed. Although the majority of the people dont have a temporal fossa depression that merits attention, it is not an uncommon occurrence. ...

As most of the eye specialists in this country and also of Great Britain whom we generally follow make special study of the diseases of the eye alone, they very often overlook this aspect of the watering of the eyes and fail to give relief to their patients by the usual eye drops. The Americans who are the most practical nation in the world have realised its importance long ago and in America the specialists always combine ophthalmic knowledge with the specialised knowledge of the diseases of the ear, nose and throat ...
Motor vehicle and bicycle accidents are the most common causes of blunt head trauma. Other common etiologies are falls, physical violence, and sports accidents. Blunt trauma toward the superior orbital rim, lateral orbital rim, frontal region, and cranium may lead to intraorbital hematoma. A fracture following the blunt head trauma may form a one-way valve, which leads to orbital emphysema and a more pronounced increase in orbital pressure. Increased tissue pressure in an enclosed space will eventually lead to an inevitable decrease in tissue perfusion. It is important to treat the patient within the first 48 hours following the trauma, which is accepted as the "critical period." In this report we present a case involving a 42-year-old man who was admitted to our clinic with left periorbital pain, edema, proptosis, and blurred vision after experiencing physical violence. The medical history and physical examination findings, along with imaging studies and a description of the endoscopic orbital ...
Penetrating orbital injuries pose a serious threat to vision, ocular motility, and in some cases, life. Long, sharp stiletto objects may penetrate deeply, causing catastrophic damage to orbital structures, despite seemingly trivial entry wounds. The authors present two cases of penetrating orbital injuries by stiletto objects, both entering via small eyelid wounds. Traumatic optic neuropathy occurred in both cases, and was treated with corticosteroids, however the globes escaped direct injury. Injuries to the IIIrd and VIth cranial nerves were also observed. Deep orbital injuries must be excluded in patients presenting with small eyelid wounds caused by sharp penetrating objects.. ...
We previously described a significant response to RTX treatment in patients with active TAO, with no effect on TRAb and hyperthyroidism. In order to study the effect of RTX in the orbit, we analyzed the orbital tissues of 9 patients with TAO at decompression after RTX (n.2) or other treatments. Decompression was carried out in 2 patients for sight threatening optic neuropathy and in 7 for correction of proptosis. Of the RTX treated patients, one was decompressed after 12 months because of optic neuropathy, while the other after 23 months with burnt out disease. Of the other 7 patients, one was decompressed for the second time because of relapse of optic neuropathy that did not respond to steroids and 6 had burnt out disease of 15-175 months of duration. Immunohistochemistry of orbital fat and muscle showed presence of infiltrating immune cells in all patients. Infiltrates were present independently of the duration and the type of treatment of TAO and of thyroid disease. Interestingly, in the ...

However, we find that the incidence of injury is significantly higher in the pure fracture group suggesting that a different mechanism is at play. It is more reasonable to envision that the acute rise in orbital pressure would lead not only to the floor fracturing, but also to a greater incidence of intraocular injury as the globe retropulses. One could argue, however, that in the case of the impure fracture, the rate of injury is lower because the force is blunted by the rim. Nevertheless, we believe that these data suggest that the retropulsion theory might possibly be the more likely explanation for orbital fractures; one theory (retropulsion) can explain variations of ocular findings in both pure and impure fractures ...

Enophthalmos is the posterior displacement of the eyeball within the orbit due to changes in the volume of the orbit (bone) relative to its contents (the eyeball and orbital fat), or loss of function of the orbitalis muscle. It should not be confused with its opposite, exophthalmos, which is the anterior displacement of the eye. ...
Results Eleven orbits of six patients (five females) with a median age of 57 years (range 23-65) were included in this study. Temple-related problems consisted of cosmetically bothersome temple hollowness (n=11; 100%), masticatory oscillopsia (n=8; 73%), temple tenderness (n=4; 36%), clicking sensation (n=4; 36%) and gaze-evoked ocular pain (n=4; 36%). Nine orbits were also complicated by proptosis and exposure keratopathy. Preoperative imaging studies showed the absence of lateral wall in all 11 orbits and evidence of prolapsed lacrimal gland into the wall defect in four orbits. Intervention included the repair of the lateral wall defect with a sheet implant, orbital decompression involving fat, the medial wall or orbital floor and autologous fat transfer or synthetic filler for temple hollowness. Postoperatively, there was full resolution of masticatory oscillation, temple tenderness, clicking sensation and gaze-evoked ocular pain, and an improvement in temple hollowness. Pre-existing ...

Head extended so that frontal lobes fall back by gravity. Do not use lumbar drain because much higher chance of extradural hematoma because frontal lobe often sunken at the end of surgery with drainage of CSF.. Bicoronal curvy incision results in better hair growth than straight one. Skin incision does not need to go all the way down to zygomatic arches unless pterygonal approach is needed as well. In that case head is tilted slightly toward that side. Harvest pericranium for repair using wet gauze to wipe the pericranium off the bone. Temporalis fascia may be harvested toward end of operation if needed for dural repair. Burr holes are made either above lateral orbital rim or behind depending on the amount of exposure needed.

Its terminal branches, escaping from the gland, are distributed to the eyelids and conjunctiva: of those supplying the eyelids, two are of considerable size and are named the lateral palpebral arteries; they run medially in the upper and lower lids respectively and anastomose with the medial palpebral arteries, forming an arterial circle in this situation. The lacrimal artery also give off one or two zygomatic branches, one of which passes through the zygomatico-temporal foramen, to reach the temporal fossa, and anastomoses with the deep temporal arteries; another appears on the cheek through the zygomatico-facial foramen, and anastomoses with the transverse facial. A recurrent branch passes backward through the lateral part of the superior orbital fissure to the dura mater, and anastomoses with a branch of the middle meningeal artery. ...

Over the last 4 years I have primarily utilized a temporal endoscopic plane approach (between the superficial and deep temporalis fascia) with or without the use of the endoscope to reshape the brow contour. My focus has been a temporal lift only. In my experience, in most cases, lifting the medial brow is an error which changes normal eyelid and periorbital, and ultimately, facial proportions. Most who need medial brow elevation also have bunching of glabellar tissue, and I have found benefit most from a central pretrichial approach (with tissue excision) combined with the temporal lift described below.. The procedure proceeds with standard temporal approach sub-superficial temporal fascia access to the canthus. This plane is made continuous with the central subperiosteal space by dividing the conjoint tendon. Dissection continues to the arcus marginalis periosteum at the superior orbital rim. The periosteum is released from the supraorbital neurovascular bundle laterally to the canthus. It is ...

Thyroid Eye Disease Your doctor thinks you have thyroid orbitopathy. This is an autoimmune condition where your bodys immune system is producing factors that stimulate enlargement of the muscles that
Treatment is essential to protect the cornea and the optic nerve from getting permanently damaged. In the initial stages of the disease, lubricating drops are used to keep the eye moist. Most patients must be started on steroid tablets for a few months to control the progression of the disease. Closure of the lids may be required if the lids are not able to completely cover the eyes. The closure is temporary and is done only on the outer part of the lids, leaving the cornea clear so that vision is not affected. If protrusion of the eyeball is too great the optic nerve is in danger. At this stage, orbital decompression is advised. This surgery involves breaking one or more walls of the orbit in order that the extra fat, which has been deposited in the orbit due to thyroid eye disease, may be displaced out of the orbit. The eyeball can then be pushed back into the orbit. A patient who has suffered from thyroid eye disease for a long time develops eye movement disorders and requires eye muscle ...

In fact, the Sandman hasnt seen the second round of a fight in five-and-a-half years, making him an ideal fit for XARMs "Roughest 3 Minutes In Sports" mentality. But theres no way hes getting out of this thing unscathed. Its James Irvin, for Gods sake. Shattering his wrist or orbital bone would be a best-case scenario. Something freaky is going to happen, I just know ...
The globe or ball of the eye is a composite structure of spheroidal form, placed in the fore part of the orbital cavity, and receiving the thick stem of the optic nerve behind. The recti and oblique muscles closely surround the greater part of the eyeball, and are capable of changing its position within certain limits: the lids, with the plica semilunaris and caruncle, are in contact with its covering of conjunctiva in front; and behind it is supported by a quantity of loose fat and connective tissue.. ...
Every May 26th since 1998, Australians have celebrated their National Sorry Day to express regret to the so-called "stolen generations," the half-caste Aboriginal children who for decades were forcibly removed from their homes and placed "for their own good" in training schools to become servants to white families and be assimilated into white society. As depicted in the film Rabbit-Proof Fence, in stealing children from their parents, the government also stole from the children themselves-their precious heritage of family and culture.. As Australia continues to seek healing and reparation for that colossal injustice, it now finds itself in the throes of another titanic issue threatening to affect its children: the debate over same-sex marriage. This is the final week for Australians to register for the postal survey, a non-binding plebiscite. As the fierce debate continues, the same line is being trumpeted that has persuaded only a mere 24 nations, according to data published by the Pew ...
Management of any orbital tumor depends upon whether it is likely to be benign or cancerous. Well-localized benign tumors are often removed completely, using minimally invasive techniques via hidden incisions. Though orbital tumors can also be removed by a neurosurgeon via a brain-surgery approach, it is far less invasive to get it done from an orbital surgeon. Histopathological confirmation is the best way to ensure complete removal and to know the exact diagnosis. Reconstruction of the orbit after removal of the mass is dependent on the size and location of the defect. Various reconstruction options are available ...

Blowout fractures in the medial orbital wall may lead to enophthalmos, ocular dysmotility, and diplopia. Ten consecutive patients with unilateral, isolated fractures of the medial orbital wall were retrospectively studied. The radiologic accuracy of the medial orbital wall reconstructions and the long-term clinical outcomes were assessed. All cases were treated through a bicoronal approach and by use of porous polyethylene-titanium implants. The total fracture area and the orbital volume increase from the blowout were measured on computed tomographic scans. Next, we evaluated the reconstruction in the posterior part of the medial wall. This was done by calculating the ratio between the defect area and the implant area located behind the anterior ethmoidal canal. The patients were examined at least 1 year after the operation, and the rates of enophthalmos and diplopia were evaluated. The mean fracture defect area was 2.45 cm(2) (range, 0.41-4.16 cm(2)), and the mean volume increase from the ...
The re-establishing of exact orbital volumes is a main goal in orbital reconstruction to avoid long-term sequelae [14-16]. Measurement of the orbital volume is reliable and three-dimensional shape analysis allows for post-operative reconstruction control as far as radioopaque reconstruction material was applied.. Orbital volume was significantly enlarged in complex orbital trauma that meets the authors indication for the use of navigation-assisted surgery. In minor orbital trauma, such as orbital floor fractures limited to the anterior third, the degree of the orbital enlargement was not significant compared to the unaffected side. That could be because of the normal existing facial asymmetry [17] or bony variability [18]. Different studies with comparable volumetric methods state that enophthalmos is mainly related to enlargement of the bony orbit and exact reconstruction and repositioning of orbital soft tissue will correct or at least significantly improve post-traumatic enophthalmos, ...
Thyroid eye disease (Graves ophthalmopathy): Find the most comprehensive real-world symptom and treatment data on thyroid eye disease at PatientsLikeMe. 22 patients with thyroid eye disease experience fatigue, depressed mood, pain, anxious mood, and insomnia and use Amphetamine-Dextroamphetamine, Bupropion, and Oxycodone-acetaminophen to treat their thyroid eye disease and its symptoms.
Thyroid eye disease is known by many other terms, including TED, infiltrative thyroid ophthalmopathy, Graves eye disease, Graves ophthalmopathy, thyroid-associated ophthalmopathy (TAO), and von Basedows ophthalmopathy. TED or TAO is an autoimmune process that was described by Graves in 1835 and by von Basedow in 1840. Thyroid eye disease may be associated with other autoimmune disorders such as Hashimotos thyroiditis.
Graves ophthalmopathy (also known as thyroid eye disease (TED), dysthyroid/thyroid-associated orbitopathy (TAO), Graves orbitopathy (GO)) is an autoimmune inflammatory disorder of the orbit and periorbital tissues, characterized by upper eyelid retraction, lid lag, swelling, redness (erythema), conjunctivitis, and bulging eyes (exopthalmos). It occurs most commonly in individuals with Graves disease, and less commonly in individuals with Hashimotos thyroiditis, or in those who are euthyroid. It is part of a systemic process with variable expression in the eyes, thyroid, and skin, caused by autoantibodies that bind to tissues in those organs. The autoantibodies target the fibroblasts in the eye muscles, and those fibroblasts can differentiate into fat cells (adipocytes). Fat cells and muscles expand and become inflamed. Veins become compressed, and are unable to drain fluid, causing edema. Annual incidence is 16/100,000 in women, 3/100,000 in men. About 3-5% have severe disease with intense ...

The white-eyed blowout fracture is an orbital injury in children that is commonly initially misdiagnosed as a head injury because of predominant autonomic features and lack of soft-tissue signs. We present five patients who presented with nausea and vomiting following an apparent mild head or facial injury. None of the five had any external evidence of injury. Despite each case describing diplopia, there was a delayed diagnosis of at least 24 h. CT examination demonstrated an inferior orbital wall fracture in all cases with entrapment of the inferior rectus muscle. Each patient underwent surgical repair, two within 48 h of their injury, both of whom achieved complete recovery of ocular movements, while three were delayed beyond 48 h, with a resulting residual limitation of upgaze in all. It is, therefore, important for clinicians to be aware of this condition, so that it can be diagnosed early in order for early surgical release to be performed, which is associated with an excellent ...
In most cases, thyroid eye disease clears up on its own time, but the disease can continue to develop and worsen. A mild stage of thyroid eye disease may need a patient to get regular check-ups and ointments to help fix the problem. But, if the disease is severe enough, twenty-five percent of those patients will lose their eye sight over time with no remedy able to help.. When thyroid eye disease takes place for the first time, patients are in the inflammatory or active stage of the disease. This stage can last for as little as a few months or up to three years. The tissue and muscles in the eye and around the eye are constantly reacting to the issue, and are trying to heal it.. Symptoms of thyroid eye disease can affect all parts of the eye and any skin or tissue around the eye itself, leading to a multitude of troubles. Some of these troubles may include double vision, red and agitated eyes, eyes that are watery, eyes that look like they are bulging out of the sockets, and problems completely ...
After reading this blog post you might not be sure if taking a natural treatment approach is the best option for your thyroid eye disease condition. After all, I mentioned how taking natural anti-inflammatory agents and selenium can help, but I also explained the importance of detecting and removing the autoimmune trigger. And so it can be challenging to overcome thyroid eye disease naturally.. However, I do think that most people with thyroid eye disease should consider taking a natural treatment approach. And the reason for this is because the conventional medical treatment methods dont do anything to address the underlying cause of the condition. So for example, if you choose to receive radioactive iodine or a thyroidectomy, not only is there a chance that your thyroid eye disease symptoms can worsen (especially with RAI), but neither of these procedures will do anything to improve the health of your immune system. And as I have mentioned in previous blog posts and articles, the research ...

Graves ophthalmopathy, also known as thyroid eye disease, is common in people with Graves Disease, and involves the thyroid antibodies attacking the tissues of the eyes. Graves ophthalmopathy is clinically relevant in approximately 50% of patients with Graves disease, with severe forms affecting 3%-5% of patients (1). In fact, many people consult with me not due to the high pulse rate, palpitations, or the other symptoms associated with Graves Disease, but instead are primarily concerned with their eye symptoms. And most people want to know if there are any supplements or herbs they can take to help with this condition.. Before I discuss some natural approaches to help with thyroid eye disease, Id first like to talk about the conventional medical treatment approach to this condition. Although radioactive iodine is commonly recommended to people with Graves Disease, RAI can worsen ophthalmopathy, especially if it is administered to those patients who smoke, have a severe case of ...
A retrospective study of patients with orbital fractures had 48% patients in the age group of 20 - 40 years with male : female ratio of 10:1. Road traffic accidents (71.43%) were the most common cause followed by injury due to fall (20%). Eighty five percent of patients had normal visual acuity at presentation and 65.57% patients had no ocular complaints. Diplopia was present in 14.2% of patients. Of the orbital fractures infraorbital rim was involved in 43.13%, floor in 19.6%, lateral wall in 13.7%, pure blow out in 14.28% and the roof in 2.9%. Important ocular findings were extraocular movements restriction in 9 (10.3%), infraorbital dysaesthesia in 3 (3.4%), enophthalmos in 2, RAPD and globe rupture in 1 patient each. 32 patients underwent surgical management. At the end of 4 months of follow up, 3 had restriction of EOM, 1 patient had vision loss due to globe rupture, 2 had RAPD (optic nerve compression), 1 had lagophthalmos, 1 had exotropia and 1 had atrophic bulbi. ...
Graves orbitopathy (GO) is a significant problem in about 5% to 10% patients with Graves disease. Glucocorticoids are the principal medical therapy for active moderate-to-severe GO but are not very effective in many patients. Rituximab is a selective immunosuppressive drug that has been reported to be effective in the treatment of GO. The current study is a clinical trial of rituximab (RTX) versus the glucocorticoid drug methylprednisolone (MP) in patients with moderate-to-severe GO.

Each year, approximately 1 million Americans are diagnosed with thyroid eye disease, also known as Graves disease. Thyroid eye disease is an autoimmune disorder that targets the muscles and soft tissues within the eye. It affects women five to six times more often than men. Many patients have mild to moderate forms of the disease, which does not result in vision loss but can include burdensome symptoms, such as dry and irritated eyes, double vision, and disfigurement. About 10 percent of patients will have sight-threatening disease, which may lead to permanent vision loss, most often caused by compression of the optic nerve, or optic neuropathy.. A limited number of management options exist for those facing optic neuropathy. Nonsurgical treatments include immunosuppression with corticosteroids or other stronger agents and radiation therapy. In the most severe cases, surgery may be required. The surgery, called orbital decompression, involves removing portions of a patients eye sockets to allow ...
Thyroid eye disease, also known as Graves disease, is the most common orbital disorder. It is an autoimmune condition that occurs as a result of impaired function of the thyroid gland. The disease may vary in severity and last several months or years. The most common side effects of thyroid eye disease are eyelid retraction, double vision and protrusion of one or both eyes. Treatments for thyroid eye disease include lubricating eye drops, medication to reduce the orbital inflammation, prisms, and eye muscle and eyelid surgery. In extreme cases, a procedure known as orbital decompression may be performed to reduce bulging eyeballs ...

BACKGROUND: The meningo-orbital band (MOB) is a dural structure which runs around the superior orbital fissure (SOF) tethering the frontotemporal basal dura to the periorbita, through the SOF. MOB division is important to expose and remove the anterior clinoid process, to access to proximal carotid artery and cavernous sinus area. The goal of the study was to measure how the MOB could be safely incised without cranial nerves and cavernous sinus injuries ...
Intraocular foreign bodies are a major cause of ocular trauma and blindness. Young adults, especially men, are the most likely victims, as a result of industrial or agricultural injuries. The management of orbital foreign bodies remains a serious diagnostic problem, despite development of diagnostic imaging techniques.
The oculomotor nerve is responsible for several parasympathetic functions related to the eye. The oculomotor PSN fibers originate in the Edinger-Westphal nucleus in the CNS and travel through the superior orbital fissure to synapse in the ciliary ganglion located just behind the orbit (eye). From the ciliary ganglion, the postganglionic PSN fibers leave via short ciliary nerve fibers, a continuation of the nasociliary nerve (a branch of ophthalmic division of the trigeminal nerve, CN V1). The short ciliary nerves innervate the orbit to control the ciliary muscle (responsible for accommodation) and the sphincter pupillae muscle, which is responsible for miosis or constriction of the pupil (in response to light or accommodation) (Netter and Hansen 2003).. The parasympathetic aspect of the facial nerve controls secretion of the sublingual and submandibular salivary glands, the lacrimal gland, and the glands associated with the nasal cavity. The preganglionic fibers originate within the CNS in the ...

Ambient light levels influence visual system size in birds and primates. Here, we argue that the same is true for humans. Light levels, in terms of both the amount of light hitting the Earths surface and day length, decrease with increasing latitude. We demonstrate a significant positive relationship between absolute latitude and human orbital volume, an index of eyeball size. Owing to tight scaling between visual system components, this will translate into enlarged visual cortices at higher latitudes. We also show that visual acuity measured under full-daylight conditions is constant across latitudes, indicating that selection for larger visual systems has mitigated the effect of reduced ambient light levels. This provides, to our knowledge, the first support that light levels drive intraspecific variation in visual system size in the human population ...
