Bleeding behind the retina, most often due to diabetic retinopathy or injury, can push it forward. Exophthalmos Enophthalmos Orbital cellulitis Orbital lymphoma Periorbital cellulitis. To evaluate the blood vessels in the retina, a fluorescent dye fluorescein may be injected into a vein and photographed with ultraviolet light as it passes through the retina.
Two outpatient modes of therapy currently in use are photocoagulationusing the light source of an argon laser; and cryosurgeryin which a freezing probe is used to penetrate the tissues of the eye and encircle the hole or tear in the retina. If just a part of the retina is involved, there will be a blind spot that may not even be noticed. Diabetic retinopathy — Disease that damages the blood vessels in the back of the eye caused by diabetes.

A high Body Mass Index BMI and elevated blood pressure have been identified as a risk factor in non-myopic individuals. Because the choroid supplies the photoreceptors with nutrients, a detachment can basically starve the photoreceptors.
A separation of the sensory retina from the retinal pigment epithelium due to fluid accumulating in the subretinal space in the absence ablaio a retinal break or preretinal traction following damage to the blood-retina barrier of the choriocapillaris. This strict positioning requirement makes the treatment of the retinal holes and detachments that occurs in the lower part of the eyeball impractical.
An advantage of using gas in this operation is that there is no myopic shift after the operation and gas is absorbed within a few weeks. Long cellular processes extend to and between the photoreceptor cells in the next layer.
