The discomfort will usually settle gradually over 2 weeks, and he eye usually looks white again at 4-6 weeks after surgery. You will be given eye drops to help prevent infection and to control any swelling. There may be some bruising and your eyelids may be sticky. Most procedures are performed under local anaesthesia, although an external procedure is more often performed under general anaesthesia.Īfter the surgery, your eye will feel uncomfortable. Some patients, however, will need more than one procedure to repair the RD. The patient is usually asked to posture on his/her side or sitting up for 10 days post operatively.Įarly treatment can usually improve the visual acuity of most patients with RD. In some cases, the vitreous cavity is subsequently filled with silicone oil (for complex RDs). Vitrectomy is performed through 3 small key holes in the sclera (white of the eye). Vitrectomy is almost always necessary in case of an extensive or complicated RD. In most cases, retinal detachment treatment is performed through an internal approach called “vitrectomy” which involves the removal of the vitreous jelly that fills the vitreous cavity, the closure of the retinal break with laser laser or cryopexy (freezing) and the placement of a gas bubble in the vitreous cavity.
The eye is red after surgery for approximately 2-4 weeks. The buckle is usually not removed and is not visible once surgery is finished. Cryopexy or laser treatment are also necessary to seal the retinal break (or breaks). In some cases a scleral buckle, a tiny synthetic band, is attached to the outside of the eyeball to gently push the wall of the eye against the detached retina. This is almost always performed as a day case procedure. Depending on the size and position of the bubble, your vision may be blurred for the first few weeks. Retinal detachments are treated with surgery that may require the patient to stay in hospital.Ī pneumatic retinopexy is a relatively simple procedure performed under local anaesthesia and involves the injection of a gas bubble in the eye, and cryopexy to close the break. Internal procedure: pars plana vitrectomy.If retinal detachment is not treated then you will lose all the vision in the affected eye. In general, the sooner treatment is carried out, the better the likely results, but in some cases the timing of surgery does not influence outcome (you therefore need to discuss timing of surgery with your Consultant). If the holes or tears are associated with a RD, surgery is required. These procedures are usually performed in an outpatient setting (in clinic). Small holes and tears (without RD) are treated with laser surgery or cryopexy (a freeze treatment). This is called an exudative or serous retinal detachment. This scar tissue can then pull on the retina causing a tractional retinal detachment.Ī less common cause of retinal detachment happens because of another condition such as inflammation or tumour in the eye. Other eye conditions such as diabetic retinopathy can result in fibrous scar tissue forming inside the vitreous and on the surface of the retina. A strong family history of retinal detachment.High myopia (> -6 D) and lattice retinal degeneration.A recent posterior vitreous detachment (conversely, most patients who develop a posterior vitreous detachment do not develop a retinal detachment).Risk factors for retinal detachment include: I will refer to rhegmatogenous retinal detachments as RD in the rest of the text.Īlthough anyone can experience a retinal detachment (1:10,000 people per year), people with certain eye conditions are at increased risk of retinal detachment. This is the most common type of retinal detachment. For the purpose of this guide, I will limit my discussion to the rhegmatogenous type of detachment (ie caused by a tear or break in the retina). There are different types of retinal detachments.
#Normal retina symptoms professional#
Anyone experiencing the symptoms of a retinal detachment should see an eye care professional immediately. A retinal detachment is a medical emergency.
Symptoms include a sudden or gradual increase in the number of floaters and/or light flashes in the eye or the appearance of a curtain over the field of vision (that is loss of vision in the peripheral field of vision). A retinal tear, hole (or break) can lead to a retinal detachment. If not promptly treated, retinal detachment can cause permanent vision loss. When the retina detaches, it is lifted or pulled away from its normal position. The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain.
