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.

Suprachoroidal haemorrhage. Secondary management. (8/21)We report a case of successful management of expulsive suprachoroidal haemorrhage following cataract surgery. This case study highlights the strategy of adequate management. (+info)
The symptoms of a choroid hemorrhage may include:
* Sudden and severe pain in one eye
* Blurred vision or vision loss
* Sensitivity to light
* Flashes of light
* Floaters (specks or cobwebs in vision)
The diagnosis of a choroid hemorrhage is typically made through a comprehensive eye exam, which may include imaging tests such as fluorescein angiography or optical coherence tomography.
Treatment for a choroid hemorrhage depends on the cause and severity of the condition. In some cases, no treatment may be necessary, and the hemorrhage may resolve on its own over time. However, in more severe cases, treatment may involve:
* Laser photocoagulation to stop the bleeding and prevent further damage
* Injection of medications into the eye to reduce inflammation and prevent scarring
* Surgery to remove the blood and repair any damage to the retina or choroid.
It is important to seek medical attention immediately if you experience sudden and severe vision loss or other symptoms of a choroid hemorrhage, as prompt treatment can help to prevent long-term vision loss and improve outcomes.
Example sentence: The patient had a hemorrhage after the car accident and needed immediate medical attention.
Symptoms of cerebral hemorrhage may include sudden severe headache, confusion, seizures, weakness or numbness in the face or limbs, and loss of consciousness. The condition is diagnosed through a combination of physical examination, imaging tests such as CT or MRI scans, and laboratory tests to determine the cause of the bleeding.
Treatment for cerebral hemorrhage depends on the location and severity of the bleeding, as well as the underlying cause. Medications may be used to control symptoms such as high blood pressure or seizures, while surgery may be necessary to repair the ruptured blood vessel or relieve pressure on the brain. In some cases, the condition may be fatal, and immediate medical attention is essential to prevent long-term damage or death.
Some of the most common complications associated with cerebral hemorrhage include:
1. Rebleeding: There is a risk of rebleeding after the initial hemorrhage, which can lead to further brain damage and increased risk of death.
2. Hydrocephalus: Excess cerebrospinal fluid can accumulate in the brain, leading to increased intracranial pressure and potentially life-threatening complications.
3. Brain edema: Swelling of the brain tissue can occur due to the bleeding, leading to increased intracranial pressure and potentially life-threatening complications.
4. Seizures: Cerebral hemorrhage can cause seizures, which can be a sign of a more severe injury.
5. Cognitive and motor deficits: Depending on the location and severity of the bleeding, cerebral hemorrhage can result in long-term cognitive and motor deficits.
6. Vision loss: Cerebral hemorrhage can cause vision loss or blindness due to damage to the visual cortex.
7. Communication difficulties: Cerebral hemorrhage can cause difficulty with speech and language processing, leading to communication difficulties.
8. Behavioral changes: Depending on the location and severity of the bleeding, cerebral hemorrhage can result in behavioral changes, such as irritability, agitation, or apathy.
9. Infection: Cerebral hemorrhage can increase the risk of infection, particularly if the hemorrhage is caused by a ruptured aneurysm or arteriovenous malformation (AVM).
10. Death: Cerebral hemorrhage can be fatal, particularly if the bleeding is severe or if there are underlying medical conditions that compromise the patient's ability to tolerate the injury.
The symptoms of choroid plexus neoplasms vary depending on their size, location, and severity, but they may include:
* Nausea and vomiting
* Weakness or numbness in the arms or legs
* Vision problems
* Endocrine disturbances (such as diabetes insipidus)
The diagnosis of choroid plexus neoplasms is typically made through a combination of imaging studies, such as MRI or CT scans, and tissue sampling, such as biopsy or surgical resection. Treatment options for these tumors depend on their size, location, and severity, but they may include:
* Observation and monitoring
* Surgery to remove the tumor
* Radiation therapy to destroy the tumor cells
* Chemotherapy to kill the tumor cells
* Targeted therapy to attack specific molecules involved in the growth and progression of the tumor
Some common types of choroid plexus neoplasms include:
* Papilloma: A benign tumor that grows from the choroid plexus.
* Choroid plexus carcinoma: A malignant tumor that grows from the choroid plexus.
* Mixed glioma: A tumor that is made up of both benign and malignant cells.
The prognosis for patients with choroid plexus neoplasms depends on several factors, including the size and location of the tumor, the patient's age and overall health, and the effectiveness of treatment. In general, patients with small, benign tumors have a good prognosis, while those with larger, more aggressive tumors may have a poorer prognosis.
It is important to note that choroid plexus neoplasms are relatively rare, and there is ongoing research into their causes, diagnosis, and treatment. If you or someone you know has been diagnosed with a choroid plexus neoplasm, it is best to consult with a qualified healthcare professional for more information and personalized advice.
There are several types of intracranial hemorrhage, including:
1. Cerebral hemorrhage: Bleeding within the cerebral tissue itself, which can cause damage to brain cells and lead to a variety of complications.
2. Subarachnoid hemorrhage: Bleeding between the brain and the thin membrane that covers it (the meninges), which can cause severe headaches and other symptoms.
3. Epidural hemorrhage: Bleeding between the dura mater, a protective layer of tissue surrounding the brain, and the skull.
4. Subdural hemorrhage: Bleeding between the dura mater and the arachnoid membrane, which can cause severe headaches and other symptoms.
The symptoms of intracranial hemorrhage can vary depending on the location and severity of the bleeding, but may include:
* Sudden, severe headache
* Nausea and vomiting
* Confusion and disorientation
* Weakness or numbness in the face, arm, or leg
* Loss of consciousness
Diagnosis is typically made through a combination of physical examination, imaging tests (such as CT or MRI scans), and laboratory tests to determine the cause of the hemorrhage. Treatment depends on the location and severity of the bleeding, but may include medications to control symptoms, surgery to repair the source of the bleeding, or other interventions as needed.
Retinal hemorrhage can cause vision loss or blindness if not treated promptly. The bleeding can lead to scarring, which can cause permanent damage to the retina and affect vision. In some cases, retinal hemorrhage can be a sign of a more serious underlying condition that requires immediate medical attention.
Retinal hemorrhage is diagnosed through a comprehensive eye exam, which includes a visual acuity test, dilated eye exam, and imaging tests such as fluorescein angiography or optical coherence tomography. Treatment options for retinal hemorrhage depend on the underlying cause and can include laser surgery, medication, or vitrectomy.
In summary, retinal hemorrhage is a serious condition that can cause vision loss or blindness if not treated promptly. It is essential to seek medical attention if symptoms such as blurred vision, flashes of light, or floaters are noticed. Early detection and treatment can help prevent or reduce vision loss in cases of retinal hemorrhage.
Some common types of choroid neoplasms include:
1. Choroidal melanoma: A malignant tumor that arises from the pigment-producing cells of the choroid. It is the most common type of primary intraocular cancer and can spread to other parts of the body if left untreated.
2. Choroidal hemangioma: A benign tumor that arises from the blood vessels of the choroid. It can cause changes in vision and may require treatment to prevent complications.
3. Choroidal naevus: A benign growth that occurs in the choroid and can be inherited. It is usually asymptomatic but can sometimes cause changes in vision.
4. Other rare types of choroid neoplasms include choroidal lymphoma, choroidal osteochondromatosis, and choroidal metastasis (metastasis of cancer from another part of the body to the choroid).
Choroid neoplasms can be diagnosed using a variety of tests, including imaging studies such as ultrasound, CT or MRI scans, and visual field testing. Treatment options vary depending on the type and location of the neoplasm, and may include observation, laser therapy, photodynamic therapy, or surgery.
Overall, choroid neoplasms are complex and varied conditions that require careful evaluation and treatment by an ophthalmologist or other eye care professional to prevent complications and preserve vision.
The term "papilloma" comes from the Latin words "papilla," meaning "nipple," and "oma," meaning "tumor." This refers to the characteristic nipple-like appearance of the tumor. The word "choroid" refers to the layer of tissue in which the tumor originates, and "plexus" refers to the network of blood vessels within the choroid plexus.
Papilloma, Choroid Plexus is a rare type of brain tumor that usually occurs in adults, although it can also be found in children. It tends to grow slowly and may not cause any symptoms until it has reached a significant size. Symptoms can include headaches, seizures, weakness or numbness in the arms or legs, and changes in vision or balance.
Treatment for Papilloma, Choroid Plexus usually involves surgery to remove the tumor, and the prognosis is generally good if the tumor is completely removed. However, if the tumor is not fully resected (removed), it can recur and may be difficult to treat.
Postpartum hemorrhage can be caused by various factors, including:
1. Uterine atony: This occurs when the uterus fails to contract properly after delivery, leading to excessive bleeding.
2. Lacerations or tears in the genital tract: Tears in the vaginal tissues, cervix, or uterus can cause bleeding.
3. Placenta accreta or placenta praevia: These conditions occur when the placenta attaches abnormally to the uterine wall, causing bleeding during delivery.
4. Cervical insufficiency: This occurs when the cervix is unable to support the weight of the baby, leading to bleeding.
5. Blood coagulopathy disorders: These are rare conditions that affect the body's ability to form blood clots, leading to excessive bleeding.
Symptoms of PPH may include:
1. Heavy bleeding within the first 24 hours post-delivery
2. Soaking more than two pads per hour
3. Pale or clammy skin
4. Weak or rapid pulse
5. Shallow breathing
6. Confusion or disorientation
Treatment for PPH may include:
1. Observation and monitoring of vital signs
2. Administration of oxytocin to stimulate uterine contractions
3. Use of a blood transfusion to replace lost blood volume
4. Surgical intervention, such as suturing or repairing any lacerations or tears
5. Management of underlying causes, such as blood coagulopathy disorders
Prevention of PPH includes:
1. Proper prenatal care and monitoring of the mother's health during pregnancy
2. Use of cesarean delivery if necessary
3. Avoidance of excessive forceps or vacuum extraction during delivery
4. Use of oxytocin and other medications to stimulate uterine contractions
5. Close monitoring of the mother's vital signs after delivery
It is important for healthcare providers to be aware of the risk factors and symptoms of PPH, as well as the appropriate treatment and prevention strategies, in order to provide optimal care for mothers at risk of developing this condition.
The severity of GIH can vary widely, ranging from mild to life-threatening. Mild cases may resolve on their own or with minimal treatment, while severe cases may require urgent medical attention and aggressive intervention.

* Taking medications as directed to control acid reflux and other gastrointestinal conditions
* Maintaining a healthy diet and lifestyle
* Reducing stress
* Avoiding smoking and excessive caffeine consumption.
A vitreous hemorrhage is a type of eye injury that occurs when there is bleeding within the vitreous humor, the gel-like substance that fills the space between the lens and the retina of the eye. This condition can be caused by a variety of factors, such as trauma, disease, or complications during surgery.
Symptoms of Vitreous Hemorrhage
The symptoms of vitreous hemorrhage can vary depending on the severity of the injury, but may include:
* Blurred vision
* Floaters (specks or cobwebs in vision)
* Flashes of light
* Eye pain
* Redness and swelling of the eye
* Sensitivity to light
Treatment of Vitreous Hemorrhage
The treatment of vitreous hemorrhage depends on the underlying cause and severity of the injury. In some cases, the body may absorb the blood over time, and no treatment is necessary. However, if the hemorrhage is severe or causing significant vision loss, surgery may be required to remove the blood and repair any damage to the eye.
Complications of Vitreous Hemorrhage
If left untreated, vitreous hemorrhage can lead to a number of complications, including:
* Glaucoma (increased pressure in the eye)
* Retinal detachment (separation of the retina from the back of the eye)
* Cataract formation
Prevention of Vitreous Hemorrhage
While some cases of vitreous hemorrhage cannot be prevented, there are steps that can be taken to reduce the risk of developing this condition. These include:
* Wearing protective eyewear during activities that could potentially cause eye injury
* Avoiding close-range objects or activities that could cause trauma to the eye
* Getting regular eye exams to monitor for any changes or abnormalities in the eye
In conclusion, vitreous hemorrhage is a serious condition that can cause significant vision loss if left untreated. While some cases may resolve on their own over time, others may require surgical intervention to prevent complications and preserve vision. Regular eye exams and protective eyewear can help reduce the risk of developing this condition.

There are several types of eye hemorrhages, including:
1. Subretinal hemorrhage: This type of hemorrhage occurs between the retina and the choroid, and can cause vision loss if the bleeding is severe.
2. Intravitreal hemorrhage: This type of hemorrhage occurs within the vitreous humor, the gel-like substance inside the eye. It can cause clouding of the lens and vision loss.
3. Retinal hemorrhage: This type of hemorrhage occurs on the surface of the retina and can cause vision loss if the bleeding is severe.
4. Choroidal hemorrhage: This type of hemorrhage occurs within the choroid, the layer of blood vessels between the sclera and retina. It can cause vision loss if the bleeding is severe.
Eye hemorrhages can be diagnosed through a comprehensive eye exam, which includes visual acuity testing, dilated eye examination, and imaging tests such as fluorescein angiography or optical coherence tomography (OCT). Treatment for eye hemorrhages depends on the underlying cause and severity of the condition. In some cases, no treatment may be necessary, while in other cases, medication or surgery may be required to prevent further bleeding and restore vision.
