Detachment


If you see any warning signs of a retinal detachment, your eye doctor can check your eyes with a dilated eye exam. Your doctor will give you some eye drops to dilate (widen) your pupil and then look at your retina at the back of your eye.




Detachment



Depending on how much of your retina is detached and what type of retinal detachment you have, your eye doctor may recommend laser surgery, freezing treatment, or other types of surgery to fix any tears or breaks in your retina and reattach your retina to the back of your eye. Sometimes, your eye doctor will use more than one of these treatments at the same time.


Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from the layer of blood vessels that provides it with oxygen and nutrients. Retinal detachment is often accompanied by flashes and floaters in your vision.


Retinal detachment separates the retinal cells from the layer of blood vessels that provides oxygen and nourishment to the eye. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye.


Warning signs of retinal detachment may include one or all of the following: reduced vision and the sudden appearance of floaters and flashes of light. Contacting an eye specialist (ophthalmologist) right away can help save your vision.


Rhegmatogenous (reg-ma-TODGE-uh-nus). These types of retinal detachments are the most common. Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina. This fluid builds up and causes the retina to pull away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.


The retina lines the back wall of the eye, and is responsible for absorbing the light that enters the eye and converting it into an electrical signal that is sent to the brain via the optic nerve, allowing you to see. Many conditions can lead to a retinal detachment, in which the retina separates from the back wall of the eye, like wallpaper peeling off a wall.


When the retina is detached from the back wall of the eye, it is separated from its blood supply and no longer functions properly. The typical symptoms of a retinal detachment include floaters, flashing lights, and a shadow or curtain in the peripheral (noncentral) vision that can be stationary (non-moving) or progress toward, and involve, the center of vision. In other cases of retinal detachment, patients may not be aware of any changes in their vision. The severity of the symptoms is often related to the extent of the detachment.


The goal of treatment is to re-attach the retina to the back wall of the eye and seal the tears or holes that caused the retinal detachment. Several approaches can be employed to repair a retinal detachment:


Based on the characteristics of the detachment, a retina specialist can determine which approach is most suitable. In general, retinal detachment repairs succeed in about 9 out of 10 cases, though sometimes more than one procedure is required to successfully put the retina back into place.


The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. It provides the sharp, central vision needed for reading, driving, and seeing fine detail. A retinal detachment lifts or pulls the retina from its normal position. It can occur at any age, but it is more common in people over age 40. It affects men more than women and whites more than African Americans. A retinal detachment is also more likely to occur in people who:


A retinal detachment is a medical emergency. If not promptly treated, it can cause permanent vision loss. If you have any symptoms, see an eye care professional immediately. Treatment includes different types of surgery.

Next to central retinal artery occlusion, chemical burns to the eye, and endophthalmitis, it is one of the most time-critical eye emergencies encountered in the emergency setting.


Next to central retinal artery occlusion, chemical burns to the eye, and endophthalmitis, a retinal detachment is one of the most time-critical eye emergencies encountered in the ED. Retinal detachment (RD) was first recognized in the early 1700s by de Saint-Yves, but clinical diagnosis remained elusive until Helmholtz invented the ophthalmoscope in 1851.


Tragically, retinal detachments were uniformly blinding until the 1920s when Jules Gonin, MD, pioneered the first repair of retinal detachments in Lausanne, Switzerland. Today, with the advent of scleral buckling and small-gauge pars plana vitrectomy, in addition to laser and cryotherapy techniques, rapid ED diagnosis and treatment of a retinal detachment truly can be a vision-saving opportunity.


Retinal detachment refers to separation of the inner layers of the retina from the underlying retinal pigment epithelium (RPE, choroid). The choroid is a vascular membrane containing large branched pigment cells sandwiched between the retina and sclera. Separation of the sensory retina from the underlying RPE occurs by the following 3 basic mechanisms:


Retinal detachments may be associated with congenital malformations, metabolic disorders, trauma (including previous ocular surgery), [1] vascular disease, choroidal tumors, high myopia or vitreous disease, or degeneration.


Of the 3 types of retinal detachment, rhegmatogenous RD is the most common, deriving its name from rhegma, meaning rent or break. Vitreous fluid enters the break and separates the sensory retina from the underlying RPE, resulting in detachment. [2]


Exudative or serous detachments occur when subretinal fluid accumulates and causes detachment without any corresponding break in the retina. The etiologic factors are often tumor growth or inflammation. These types of retinal detachment do not usually require surgical intervention. Correction of the underlying disorder typically leads to resolution of these detachments.


Tractional retinal detachment occurs as a result of adhesions between the vitreous gel/fibrovascular proliferation and the retina. Mechanical forces cause the separation of the retina from the RPE without a retinal break. Advanced adhesion may result in the eventual development of a tear or break. The most common causes of tractional retinal detachment are proliferative diabetic retinopathy, sickle cell disease, advanced retinopathy of prematurity, and penetrating trauma.


Although 6% of the general population are thought to have retinal breaks, most of these are asymptomatic benign atrophic holes, which are without accompanying pathology and do not lead to retinal detachment. The annual incidence is approximately one in 10,000 or about 1 in 300 over a lifetime. [2] Other sources suggest that the age-adjusted incidence of idiopathic retinal detachments is approximately 12.5 cases per 100,000 per year, or about 28,000 cases per year in the US. [3]


Certain groups have higher prevalence than others. Patients with high myopia (>6 diopters) and individuals with aphakia (ie, cataract removal without lens implant) have a higher risk. Cataract extraction complicated by vitreous loss during surgery can have an increased detachment rate of up to 10%.


The most common worldwide etiologic factors associated with retinal detachment are myopia (ie, nearsightedness), aphakia, pseudophakia (ie, cataract removal with lens implant), and trauma. Approximately 40-50% of all patients with detachments have myopia, 30-40% have undergone cataract removal, and 10-20% have encountered direct ocular trauma. Traumatic detachments are more common in young persons, and myopic detachment occurs most commonly in persons aged 25-45 years. Although no studies are available to estimate incidence of retinal detachment related to contact sports, specific sports (eg, boxing) have an increased risk of retinal detachment.


Estimates reveal that 15% of people with retinal detachments in one eye develop detachment in the other eye. Risk of bilateral detachment is increased (25-30%) in patients who have had bilateral cataract extraction.


As the population ages, retinal detachments (RDs) are becoming more common. Retinal detachment usually occurs in persons aged 40-70 years. However, paintball injuries in young children and teens are becoming increasingly common causes of eye injuries, including traumatic retinal detachments. 041b061a72
