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 ...
The blood typically clears by itself and vision is restored, though this may take up to several months. In more severe cases, or if the hemorrhage does not clear up as expected, an eye doctor may perform a vitrectomy. [10] Subretinal hemorrhage secondary to age-related macular degeneration (AMD) has a poor visual prognosis.
Subconjunctival bleeding, also known as subconjunctival hemorrhage or subconjunctival haemorrhage, is bleeding from a small blood vessel over the whites of the eye. It results in a red spot in the white of the eye. [1] There is generally little to no pain and vision is not affected. [2] [3] Generally only one eye is affected. [2]
A red eye is an eye that appears red due to illness or injury. It is usually injection and prominence of the superficial blood vessels of the conjunctiva, which may be caused by disorders of these or adjacent structures. Conjunctivitis and subconjunctival hemorrhage are two of the less serious but more common causes.
The one and a half syndrome is a rare weakness in eye movement affecting both eyes, in which one cannot move laterally at all, and the other can move only in outward direction. More formally, it is characterized by " a conjugate horizontal gaze palsy in one direction and an internuclear ophthalmoplegia in the other ".
Depending on the location and extent of the bleeding, valsalva retinopathy usually resolves within weeks to months, without any complications. [4] Patients are instructed to avoid anticoagulant drugs and physical activities which cause increase in intrathoracic or intra-abdominal pressure. [4]
Keratoconjunctivitis is a term used to describe inflammation of both the cornea (the clear, front part of the eye) and the conjunctiva (the thin, transparent membrane covering the white part of the eye and lining the inside of the eyelids). This condition can have various causes, and its presentation may vary depending on the underlying factors.
