Hemorrhage from the vessels of the choroid.
Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
Choroid Plexus Neoplasms
Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS. (From Devita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072; J Neurosurg 1998 Mar;88(3):521-8)
Bleeding from the vessels of the retina.
Papilloma, Choroid Plexus
A usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged CHOROID PLEXUS, which may be associated with oversecretion of CSF. The tumor usually presents in the first decade of life with signs of increased intracranial pressure including HEADACHES; ATAXIA; DIPLOPIA; and alterations of mental status. In children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. Malignant transformation to choroid plexus carcinomas may rarely occur. (Adams et al., Principles of Neurology, 6th ed, p667; DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072)
Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
Tomography, Optical Coherence
An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual Science, 4th ed)
Diagnostic Techniques, Ophthalmological
Methods and procedures for the diagnosis of diseases of the eye or of vision disorders.
The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.
Slender processes of NEURONS, including the AXONS and their glial envelopes (MYELIN SHEATH). Nerve fibers conduct nerve impulses to and from the CENTRAL NERVOUS SYSTEM.

Tissue Plasminogen Activator
A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
A benign brain tumor composed of neural elements which most often arise from the SEPTUM PELLUCIDUM and the walls of the lateral ventricles. Immunohistochemistry and electron microscopy evaluations may reveal expression of neuron specific enolase and synaptophysin and cells containing microtubuli, neurosecretory granules, and presynaptic vesicles. (From Acta Med Port 1994 Feb;7(2):113-9)
Diseases affecting the eye.
A scientific tool based on ULTRASONOGRAPHY and used not only for the observation of microstructure in metalwork but also in living tissue. In biomedical application, the acoustic propagation speed in normal and abnormal tissues can be quantified to distinguish their tissue elasticity and other properties.
A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.
Analog or digital communications device in which the user has a wireless connection from a telephone to a nearby transmitter. It is termed cellular because the service area is divided into multiple "cells." As the user moves from one cell area to another, the call is transferred to the local transmitter.
Encyclopedias as Topic
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
Intraoperative computer-assisted 3D navigation and guidance system generally used in neurosurgery for tracking surgical tools and localize them with respect to the patient's 3D anatomy. The pre-operative diagnostic scan is used as a reference and is transferred onto the operative field during surgery.
Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle.

New animal model for human ocular toxocariasis: ophthalmoscopic observation. (1/21)BACKGROUND/AIMS: Although human ocular toxocariasis causes severe vision defect, little is known about its aetiology, diagnosis, and treatment. To develop a new animal model for human ocular toxocariasis, ophthalmological findings of fundi in Mongolian gerbils, Meriones unguiculatus, and BALB/c mice were investigated following infection with Toxocara canis. METHODS: Using an ophthalmoscope, which was specifically developed to observe the fundi of small animals, ocular changes of fundi of 20 gerbils and 11 mice were monitored after oral infection with embryonated eggs of T canis. RESULTS: Vitreous, choroidal, and retinal haemorrhages were consistently observed in Mongolian gerbils, but rarely in mice. Severe exudative lesions and vasculitis were often present in gerbils but not in mice. Migrating larvae were also frequently observed in gerbils. CONCLUSION: Mongolian gerbils are more appropriate animal model for human ocular toxocariasis than previously used experimental animal such as mice, guinea pigs, rabbits, and monkeys because of its high susceptibility of ocular infection.

Massive suprachoroidal hemorrhage with retinal and vitreous incarceration; a vitreoretinal surgical approach. (2/21)Suprachoroidal hemorrhage(SH) may cause the expulsion of the intraocular contents. Vitreous incarceration in the wound and retinal detachment with SH are extremely poor prognostic signs. Treatment modalities depend on the severity of eye damage. This particular patient had "kissing" hemorrhagic choroidal detachment which completely filled the vitreous cavity after cataract surgery. It seemed to be inoperable. Secondary surgery was delayed 3 days to lower IOP to normal levels. The eye underwent anterior drainage sclerotomy under constantly-maintained limbal or pars plana infusion fluid line pressure. The authors performed a pars plana vitrectomy, followed by perfluorocarbon liquid injection and a silicone oil tamponade. After this surgical approach, the patient attained an attached retina and a visual acuity of 5/200 at the 3 month follow-up. (+info)
Expulsive choroidal haemorrhage. (3/21)Expulsive choroidal haemorrhage is a dramatic and serious complication of cataract surgery that occurred in five patients out of ten thousand consecutive cataract surgeries performed by the author during the year 1989 and 1990. Report about this dreaded complication after cataract surgery are scanty and as far as I can remember I have not seen any report in Indian ophthalmic literature recently. Since cataract surgery forms the major part of intra ocular surgeries performed in our country, I thought it would be appropriate to report about this rare complication which may occur to all of us. Out of five cases 3 were males and 2 were females in the age group ranging between 45-72 years. Two eyes regained vision up to 6/12 after intra operative expulsive haemorrhage. All the eyes were salvaged by doing anterior sclerotomy. Diabetes, hypertension, glaucoma and myopia are the commonest predisposing factors. (+info)
Suprachoroidal haemorrhage complicating cataract surgery in the UK: a case control study of risk factors. (4/21)AIMS: To study the risk factors for suprachoroidal haemorrhage (SCH) complicating cataract surgery in the United Kingdom. METHODS: 109 cases of SCH complicating cataract surgery prospectively collected through the British Ophthalmological Surveillance Unit were compared with 449 controls that underwent cataract extraction from 13 "control centres" throughout UK in a case control study. 40 systemic, ophthalmic, and operative variables were examined. RESULTS: Statistically significant risk factors for SCH in univariate analysis included: older age (p<0.001), taking at least one cardiovascular medication (p<0.001), peripheral vascular disease (p = 0.014), hyperlipidaemia (p = 0.005), glaucoma (p<0.001), elevated preoperative intraocular pressure (p<0.001), sub-Tenon's local anaesthesia (LA) (p<0.001), topical LA (p<0.001), the lack of orbital compression following LA (p<0.001), posterior capsule (PC) rupture before SCH (p<0.001), elective extracapsular cataract extraction (ECCE) (p = 0.038), and phacoemulsification conversion (p<0.001). Logistic regression analysis identified the following significant independent risk factors: older age, taking at least one cardiovascular medication, glaucoma, elevated preoperative intraocular pressure, the lack of orbital compression, PC rupture before SCH, elective ECCE, and phacoemulsification conversion. CONCLUSION: The results allow identification of patients at risk of SCH. Attention to the various modifiable preoperative and intraoperative risk factors is recommended in order to minimise the risk of SCH. (+info)
Suprachoroidal haemorrhage complicating cataract surgery in the UK: epidemiology, clinical features, management, and outcomes. (5/21)AIMS: To study the incidence, management, and outcomes of suprachoroidal haemorrhage (SCH) complicating cataract surgery in the United Kingdom. METHODS: Cases were prospectively collected by active surveillance through the British Ophthalmological Surveillance Unit. Details were obtained using an incident questionnaire with follow up at 6 months. RESULTS: 118 cases were reported in 1 year. The estimated incidence of SCH was 0.04% (95% confidence interval 0.034% to 0.050%). Cataract extractions were by phacoemulsification in 76.2%, extracapsular cataract extraction (ECCE) in 11.0%, and phacoemulsification conversion in 12.8%. SCH was "limited" (1 to 2 quadrants) in 48.7%, "full blown" (3 to 4 quadrants) in 43.1%. SCH in phacoemulsification was more likely to be limited (63.2%), compared with ECCE (11.1%) and phacoemulsification conversion (23.1%) (p<0.001, chi(2) test). Visual acuity (VA) was better than 6/60 in 57 of 95 (60%) cases after a median follow up interval of 185 days. 33 of 34 cases (97.1%) with secondary anterior segment revision had VA better than 6/60. VA was worse than 6/60 in 7 of 8 (87.5%) cases that had intraoperative sclerostomy, and in all 6 (100%) cases that had secondary posterior segment intervention. CONCLUSION: SCH is a rare but serious complication of cataract surgery. Poor prognostic factors included full blown SCH, ECCE, phacoemulsification conversion, retinal apposition, and retinal detachment. (+info)
Surgery for hemorrhagic choroidal neovascular lesions of age-related macular degeneration: ophthalmic findings: SST report no. 13. (6/21)PURPOSE: To present best-corrected visual acuity (BCVA) findings and other clinical outcomes from eyes of patients enrolled in one of the Submacular Surgery Trials (SST) evaluating surgical removal versus observation of predominantly hemorrhagic subfoveal choroidal neovascularization (CNV) associated with age-related macular degeneration. DESIGN: Randomized clinical trial (SST Group B Trial). PARTICIPANTS: Eligible patients had subfoveal choroidal neovascular lesions greater than 3.5 disk areas (8.9 mm2) composed of at least 50% blood (either blood or CNV underlying the center of the foveal avascular zone) and BCVA of 20/100 to light perception in the study eye. INTERVENTION: Patients were assigned randomly at time of enrollment to observation or surgical removal of blood and any associated CNV. MAIN OUTCOME MEASURE: A successful outcome was defined a priori as either improvement in visual acuity (VA), no change in VA, or a decline in VA of no more than 1 line (7 letters) from baseline to the 24-month examination based on an intent-to-treat analysis. RESULTS: Of 336 patients enrolled, 168 were assigned to each treatment arm; treatment arms were balanced by baseline characteristics. Of 1501 expected examinations 3 months through 36 months after baseline, 1370 (91%) were performed. Loss of > or =2 lines (> or =8 letters) of VA occurred in 56% of surgery eyes, versus 59% of observation eyes examined at 24 months. Although severe loss of VA was not the primary outcome of interest, surgery more often prevented such loss: 36% in the observation arm versus 21% in the surgery arm at the 24-month examination (chi2 P = 0.004). Of initially phakic eyes, the cumulative percentage that had undergone cataract surgery by 24 months was 44% in the surgery arm, compared with 6% in the observation arm. Twenty-seven eyes (16%) in the surgical arm, compared with 3 eyes (2%) in the observation arm, had a rhegmatogenous retinal detachment (RD). CONCLUSIONS: Submacular surgery as performed in the SST Group B Trial did not increase the chance of stable or improved VA (the primary outcome of interest) and was associated with a high risk of rhegmatogenous RD, but did reduce the risk of severe VA loss in comparison with observation.

Surgery for hemorrhagic choroidal neovascular lesions of age-related macular degeneration: quality-of-life findings: SST report no. 14. (7/21)PURPOSE: To present and compare findings from health-related quality-of-life (HRQOL) interviews conducted with patients enrolled in the SST Group B Trial evaluating surgical removal of subfoveal choroidal neovascular lesions associated with age-related macular degeneration versus observation. DESIGN: Randomized clinical trial. PARTICIPANTS: Eligible patients had predominantly hemorrhagic subfoveal choroidal neovascular lesions (total lesion size of >3.5 disc areas, area of blood at least 50% of the lesion area, and at least 75% of blood posterior to the equator) and best-corrected visual acuity (VA) of 20/100 to <20/1600 but at least light perception in the study eye. Three hundred thirty-six patients enrolled after baseline quality-of-life interviews, 168 assigned to each of surgery or observation. METHODS: Clinical and HRQOL data were collected before randomization and at 6, 12, 24, 36, and 48 months after enrollment. Baseline clinical evidence was used to stratify patients as having unilateral or bilateral neovascularization at the time of randomization. The HRQOL interviews included the National Eye Institute Visual Function Questionnaire (NEI-VFQ), the 36-item Short Form Health Survey, and the Hospital Anxiety and Depression Scale. MAIN OUTCOMES MEASURE: Two-year change in NEI-VFQ. RESULTS: At 24 months after enrollment, overall NEI-VFQ scores had a median decrease of 1 point from baseline in the observation arm (95% confidence interval [CI]: -4 to 3 points) and no change in the surgery arm (95% CI: -3 to 3 points) (P = 0.70). Changes from baseline on NEI-VFQ subscales also were similar between treatment arms. Differences in scores by unilateral or bilateral involvement seen at baseline in each treatment arm persisted throughout follow-up for most outcomes. Planned analyses stratified by VA showed trends (P = 0.17) in favor of surgery at 24 months in the patients with baseline VA greater than 20/200 for the NEI-VFQ scale (3.5-point median increase from baseline in the surgery arm [95% CI: -4 to 7] vs. a 1-point median loss from baseline in the observation arm [95% CI: -6 to 4]). CONCLUSIONS: No difference was detected with respect to vision-targeted quality-of-life outcomes for patients randomized to surgery or observation in the SST Group B Trial.

A spontaneous suprachoroidal haemorrhage: a case report | Cases Journal | Full Text
We present a case of spontaneous suprachoroidal haemorrhage in a patient taking Warfarin. This is only the second case reported of a patient whose anticoagulation was within the therapeutic range. An 84 year old white male with a history of end stage atrophic age related macular degeneration presented with angle closure glaucoma. The patient was taking warfarin and had a therapeutic International Normalized Ratio (INR). Ultrasound examination revealed a spontaneous suprachoroidal haemorrhage. Anticoagulation is common in those with cardiovascular disease, which increases the risk of haemorrhagic complications. These patients are also more likely to suffer from age related macular degeneration. Suprachoroidal haemorrhage should be considered in such patients presenting with suspicious signs and a low threshold should be had for investigating for this condition in such circumstances. Early detection may reduce the morbidity.
Abrupt spontaneous suprachoroidal hemorrhage post-23-gauge vitrectomy | OPTH
Abrupt spontaneous suprachoroidal hemorrhage post-23-gauge vitrectomy during peritoneal dialysis Moosang Kim, Seung-Chan Lee, Seung-Jun LeeDepartment of Ophthalmology, School of Medicine, Kangwon National University, Chuncheon, South KoreaAbstract: Herein, we report a case of abrupt suprachoroidal hemorrhage (SCH) that developed during peritoneal dialysis in a patient with proliferative diabetic retinopathy. A 53-year-old female patient visited our clinic with blurred vision due to vitreous hemorrhage and proliferative diabetic retinopathy. Her medical history included diabetes, hypertension, chronic renal failure, and she had received scheduled peritoneal dialysis. No anticoagulant agents were used. We performed combined phacoemulsification with intraocular lens implantation and vitrectomy without any complications. Two hours later, the retina was stable and the intraocular pressure (IOP) was 11 mmHg. Four hours later, while receiving peritoneal dialysis, she abruptly developed ocular pain. Examination

TY - JOUR. T1 - Clinicopathologic study of eyes obtained postmortem from a patient 6 and 2 years after operative choroidal hemorrhage.. AU - Haynes, J. H.. AU - Payne, John. AU - Green, W. R.. PY - 1987/9/1. Y1 - 1987/9/1. N2 - We present the clinicopathologic features of a patient who developed bilateral choroidal hemorrhage during cataract surgery and who regained 20/30+ vision in each eye. Consequences related to the operative procedure and choroidal hemorrhage included iris and vitreous incarceration with inferior peripheral tractional retinoschisis, retained lens cortex, and an anterior capsule fragment lodged in the anterior chamber angle. A recent choroidal hemorrhage associated with a thrombosed vortex vein was observed in one eye. The favorable outcome was likely due both to preplaced sutures that allowed immediate tamponade of the hemorrhage and to the additional possible tamponading effect of an intact posterior capsule in the left eye. The possible role of venous stasis leading to ...

Risk factors for delayed suprachoroidal haemorrhage following glaucoma surgery | British Journal of Ophthalmology
Aim: To determine the incidence, risk factors and outcomes of delayed suprachoroidal haemorrhage (DSCH) after glaucoma surgery.. Methods: A retrospective case-control study was performed at a tertiary referral eye hospital on patients who presented with DSCH following glaucoma surgery. Cases were compared with a matched-control population that underwent equivalent procedures but did not develop DSCH. The main outcome parameters were incidence of DSCH, risk factors associated with its occurrence, visual outcome and prognostic factors.. Results: Of the 2752 glaucoma surgeries performed during the 10-year recruitment period, 29 cases of DSCH (1%) were identified. An increased incidence of DSCH was observed after glaucoma drainage device implantation compared with trabeculectomy-associated DSCH (p,0.0001; odds ratio 3.4; 95% CI 1.9 to 5.4). Risk factors for DSCH included low postoperative intraocular pressure (⩽3 mm Hg; p,0.001), aphakia (p,0.001), prior intraocular surgery (p,0.002), hypertension ...

Intraoperatively, two full thickness triangular scleral flaps were created in the inferotemporal and inferonasal quadrants around the equator of the eye. Partial drainage of the haemorrhage was carried out intra operatively. The flaps were left unsutured but covered with conjunctiva which was closed with 7 `0` Vicryl suture. Approximately 0.3ml of 100% perfluropropane gas was injected into the vitreous cavity to facilitate further drainage of the haemorrhage post operatively. The suprachoroidal haemorrhage continued to drain over the next few days. The patient developed pupilllary block glaucoma four weeks after surgery. Laser iridotomy was performed and the patient scheduled for further surgery the following week. An anterior vitrectomy and anterior chamber lens implant was carried out on 8th January 2013. On follow up on 17th January 2013 the left vision improved to 6/18.The intraocular pressure however remained high at 36mmHg. The patient was advised to continue the Latanoprost eyedrops and ...

cataract surgical problem : Journal of Cataract & Refractive Surgery
This malpositioned lens needs to be surgically corrected since leaving a decentered lens, fixed dilated pupil, and eroding sutures is quite intolerable.. The IOL can be either replaced or repositioned and fixated to the adjacent structures. There seems to be no more capsular support (Figure 2). The lenses used 15 years ago were usually 13.0 mm and longer (since in 70% at least 1 loop was out of the bag), and still it was not enough for a stable fixation. Therefore, sulcus fixation alone is out of question.. Anterior chamber IOL is a reasonable option, especially the Artisan lens. However, pupilloplasty needs to be done first to ensure stable fixation and avoid diplopia.. My preference is to reposition and refixate the same IOL with minimal surgical intervention. This eye had a suprachoroidal hemorrhage in the past, probably as a result of a prolonged hypotony during the scleral fixation procedure. It is, therefore, at high risk to develop a second event if the eye is opened again. A closed ...

Baseline Ophthalmic Systems provides Perimeters from industry leading manufacturers, including Zeiss and Haag Streit, among others. The Perimeters from Baseline are fully reconditioned to factory specification by manufacturer trained technicians.. About Perimetry- A patients visual acuity can be impaired by ailments such as choroidal neovascular lesions or AMD. Perimetry is used to measure a patients sensitivity to differential light within their visual field, by displaying objects to the patient and measuring their response to them. Test objects - often just small spot of light - are projected onto a hemispherical surface. In standard static perimetry, objects of varying sizes and shapes remain fixed in position (hence static) across the visual field, but change in luminosity or size via computer control. These perimeters offer up to 80 degrees of measurement range across the hemisphere. The patients sensitivity threshold can be mapped as a traditional chart, a 3D or grayscale image, or a ...

Initially, a suprachoroidal (SC) electrode array was developed with a transscleral lead of 14-22 platinum microwires in silicone. It was implanted in cats (n = 16) for 3 months. The lead was sutured on the sclera with a silicone patch and tunnelled under conjunctiva to a patch on the orbital rim. It followed either a straight path (3 implants) of 12 mm; or a curved path (13 implants; Fig. 1) of 16 mm with 1 mm strain relief cones. Histological assessment was performed on the tissue around the lead. The lead routing was then fitted to a human orbit and tested in cadavers. This lead, with strain relief cones, was 34 mm to the lateral orbit where it was fitted inside a channel. Lead durability was then tested in a mechanical model of a skull and eye moving to 25° of abduction/adduction. A 24-channel electrode array with optimised lead and a percutaneous connector (on the parietal bone) was then implanted in a clinical pilot. The lead location was monitored with X-ray and CT imaging.. ...
Patente US20110028983 - Ocular implant with stiffness qualities, methods of implantation and system - Google Patentes
Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.
Sharon Senate64: The Bionic Eye | The Scientist Magazine®
More recently, our groups, the Bionics Institute and the Centre for Eye Research Australia, working as part of the Bionic Vision Australia (BVA) partnership, ran a series of preclinical studies between 2009 and 2012.4 These studies demonstrated the safety and efficacy of a prototype suprachoroidal implant, made up of a silicone carrier with 33 platinum disc-shaped electrodes that can be activated in various combinations to elicit the perception of rudimentary patterns, much like pixels on a screen. Two years ago, BVA commenced a pilot trial, in which researchers implanted the prototype in the suprachoroidal space of three end-stage retinitis pigmentosa patients who were barely able to perceive light. The electrode array was joined to a titanium connector affixed to the skull behind the ear, permitting neurostimulation and electrode monitoring without the need for any implanted electronics.5 In all three patients, the device proved stable and effective, providing enough visual perception to ...

In cytotoxic edema, the blood-brain barrier remains intact but a disruption in cellular metabolism impairs functioning of the sodium and potassium pump in the glial cell membrane, leading to cellular retention of sodium and water. Swollen astrocytes occur in gray and white matter. Cytotoxic edema is seen with various toxins, including dinitrophenol, triethyltin, hexachlorophene, and isoniazid. It can occur in Reye's syndrome, severe hypothermia, early ischemia, encephalopathy, early stroke or hypoxia, cardiac arrest, and pseudotumor cerebri. During an ischemic stroke, a lack of oxygen and glucose leads to a breakdown of the sodium-calcium pumps on brain cell membranes, which in turn results in a massive buildup of sodium and calcium intracellularly. This causes a rapid uptake of water and subsequent swelling of the cells. It is this swelling of the individual cells of the brain that is seen as the main distinguishing characteristic of cytotoxic edema, as opposed to vasogenic edema, wherein ...
