Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. [1] The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision, floaters ...
Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye (oculus in Latin).Bleeding can occur from any structure of the eye where there is vasculature or blood flow, including the anterior chamber, vitreous cavity, retina, choroid, suprachoroidal space, or optic disc.
Fundus photographs of the right eye (left image) and left eye (right image), as seen from the front (as if face to face with the viewer). Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disc is located towards the nose. Both optic discs have ...
Early fundus photos were limited by insufficient light, long exposures, eye movement, and prominent corneal reflexes that reduced the clarity detail. It would be several decades before these problems could be rectified. [3] There has been some controversy regarding the first-ever successful human fundus photo.
Retinal detachment should be considered if there were preceding flashes or floaters, or if there is a new visual field defect in one eye. [2] [3] If treated early enough, retinal tear and detachment can have a good outcome. [2]
It is crucial in determining the health of the retina, optic disc, and vitreous humor. [citation needed] The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination).
Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...
Intraocular bleeding, which can happen in the retina, subhyaloid space (beyond the vitreous membrane), or vitreous body, is the main cause of ocular involvement. If treatment is not received, this bleeding can cause long-term problems such retinal detachment or scarring in addition to impairing eyesight.
