Bleeding from the vessels of the retina.

Brain injuries resulted from vigorous shaking of an infant or young child held by the chest, shoulders, or extremities causing extreme cranial acceleration. It is characterized by the intracranial and intraocular hemorrhages with no evident external trauma. Serious cases may result in death.

Hemorrhage into the VITREOUS BODY.

Mild to severe infections of the eye and its adjacent structures (adnexa) by adult or larval protozoan or metazoan parasites.

Swelling of the OPTIC DISK, usually in association with increased intracranial pressure, characterized by hyperemia, blurring of the disk margins, microhemorrhages, blind spot enlargement, and engorgement of retinal veins. Chronic papilledema may cause OPTIC ATROPHY and visual loss. (Miller et al., Clinical Neuro-Ophthalmology, 4th ed, p175)

Bleeding or escape of blood from a vessel.

Abuse of children in a family, institutional, or other setting. (APA, Thesaurus of Psychological Index Terms, 1994)

Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.

The concave interior of the eye, consisting of the retina, the choroid, the sclera, the optic disk, and blood vessels, seen by means of the ophthalmoscope. (Cline et al., Dictionary of Visual Science, 4th ed)

Radiography using air, oxygen, or some other gas as a contrast medium.

A sport involving mountain climbing techniques.

Radiographic visualization of the cerebral ventricles by injection of air or other gas.

A form of analgesia accompanied by general quiescence and psychic indifference to environmental stimuli, without loss of consciousness, and produced by the combined administration of a major tranquilizer (neuroleptic) and a narcotic.

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.

Retinal diseases refer to a diverse group of vision-threatening disorders that affect the retina's structure and function, including age-related macular degeneration, diabetic retinopathy, retinal detachment, retinitis pigmentosa, and macular edema, among others.

A clinical condition resulting from repeated physical and psychological injuries inflicted on a child by the parents or caregivers.

Traumatic injuries involving the cranium and intracranial structures (i.e., BRAIN; CRANIAL NERVES; MENINGES; and other structures). Injuries may be classified by whether or not the skull is penetrated (i.e., penetrating vs. nonpenetrating) or whether there is an associated hemorrhage.

Examination of the interior of the eye with an ophthalmoscope.

Damage or trauma inflicted to the eye by external means. The concept includes both surface injuries and intraocular injuries.

Multiple symptoms associated with reduced oxygen at high ALTITUDE.

Visualization of a vascular system after intravenous injection of a fluorescein solution. The images may be photographed or televised. It is used especially in studying the retinal and uveal vasculature.

The blood vessels which supply and drain the RETINA.

Bleeding within the SKULL, including hemorrhages in the brain and the three membranes of MENINGES. The escape of blood often leads to the formation of HEMATOMA in the cranial epidural, subdural, and subarachnoid spaces.

Philadelphia, in a medical context, does not have a specific definition as it is a city and not a term used for diagnosis or clinical condition; however, it is known for being the location of several major hospitals and medical institutions, including the University of Pennsylvania Health System and the Children's Hospital of Philadelphia.

Diseases affecting the eye.

The transparent, semigelatinous substance that fills the cavity behind the CRYSTALLINE LENS of the EYE and in front of the RETINA. It is contained in a thin hyaloid membrane and forms about four fifths of the optic globe.

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).

Bleeding in any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM.

An infant during the first month after birth.
