Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
Retinal tear Experts say that retinal tears are one of the most concerning causes of eye floaters. "If the retina tears, it can release pigment or blood into the vitreous that would be seen as a ...
The goal of the treatment is to fix the cause of the hemorrhage as quickly as possible. Retinal tears are closed by laser treatment or cryotherapy, and detached retinas are reattached surgically. [6] Even after treatment, it can take months for the body to clear all of the blood from the vitreous. [2]
It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss. Procedures may include laser treatment, freezing, or surgery.
Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye. [11] Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12] Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
A Retinal Tear may also allow fluid to leak behind the retina causing it to detach. This will often leak blood into the vitreous, which is seen by the patient as a sudden appearance of numerous small black dots or ribbons moving across the field of vision.
Symptoms: Lattice degeneration itself does not cause symptoms: Diagnostic method: The only way to diagnose the condition is with a dilated fundus examination by an eye care provider. A dilated fundus examination is done by administering dilating eye drops in your eyes to expand the pupil so that the retina can be carefully evaluated.
