Park DW, 1994;101:150313. Brown CK. Campochiaro PA. (B) With aging and other factors, the gel shrinks, exerts a centripetal traction force on the retina (arrows), and eventually separates from the retina, a condition known as posterior vitreous detachment; a fluid-filled space enlarges between the retracting gel and the retinal surface. Prevention is important in the treatment of retinal detachment. Park DW, Sarrafizadeh R, For example, a small detachment in the inferior retina results in a small superior visual field defect, while a large temporal detachment causes extensive nasal field loss.

Retinal detachment is relatively uncommon, affecting only one in 10,000 people per year, or approximately one in 300 patients in the course of a life-time.1 Retinal detachment often is repaired with little or no vision loss; therefore, it is a much less significant cause of irreversible blindness than other retinal diseases, such as diabetic retinopathy and macular degeneration.2 Retinal detachment should be considered in the differential diagnosis of vision loss, however, because it is more prevalent in defined subpopulations and may require urgent surgical repair. 1998;17:416. 24. When the retina tears, blood and retinal pigment epithelium cells may enter the vitreous cavity and are perceived as floaters (Figure 2c). et al. Shrinkage and detachment of the vitreous are accelerated, and increase the risk of development to retinal tears. Choose a single article, issue, or full-access subscription. If silicone oil was used, it may be surgically removed months later. A patient may present with one or more of these types.

Early intervention facilitates prevention of retinal detachment after formation of retinal breaks and improves visual outcomes of retinal detachment surgery. Hyaluronic acid content in the developing and aging human liquid and gel vitreous. 25. The retina, the layer of tissue in the back of the eye, pulls away from tissues supporting it. 1987;1pt 2:25462. Marin MI, Pediatric retinal detachment accounts for up to 5.9% of all rhegmatogenous retinal detachments (RRD). An alternative means to relieve vitreoretinal traction is to remove the vitreous humor. It occurs when the retina develops a hole or tear and the vitreous seeps between the retina and choroid. Flynn HW Jr, Have you had any symptoms in your other eye?

Natural history of posterior vitreous detachment with early management as the premier line of defense against retinal detachment. However, if the central macula is detached at the time of repair, final visual recovery may vary from none to nearly complete, depending on the duration and degree of elevation of macular detachment and the patient's age. Olsen KR, Sudden changes, including eye floaters and flashes and darkening side vision, are signs this may be happening. Lean JS, 1998-2021 Mayo Foundation for Medical Education and Research (MFMER). Facts about retinal detachment. This site complies with the HONcode standard for trustworthy health information: verify here. Philadelphia, Pa.: Elsevier; 2017. https://www.clinicalkey.com. Therefore, surgical repair is indicated more urgently in patients with preserved central acuity, less urgently in patients whose macula detached in the previous hours to days, and routinely in those whose macula has been detached for several days or weeks. Retinal detachment: diagnosis and management. Trott JA, Tejero TR, 11. An updated classification of retinal detachment with proliferative vitreoretinopathy. At the moment of impact, rapid compression and decompression of the globe may generate sufficient vitreoretinal traction to produce retinal tears.11 Alternatively, retinal detachment may occur weeks, months, or even years after trauma because vitreous contraction is accelerated by inflammatory and blood-borne mediators that access the vitreous cavity at the time of injury.12 Despite these concerns, retinal detachment rarely follows head and periocular trauma,13,14 and fundus examination is warranted only if visual symptoms or external or radiographic evidence of ocular injury are present. The symptoms of retinal detachment often come on quickly. Byer NE. Ophthalmology. Exudative (or serous) retinal detachment results from the accumulation of serous and/or hemorrhagic fluid in the subretinal space because of hydrostatic factors (e.g., severe acute hypertension), or inflammation (e.g., sarcoid uveitis), or neoplastic effusions. American Society of Retina Specialists. 2002;109:14652. Floaters caused by acute posterior vitreous detachment, especially in the presence of a retinal tear, occur more abruptly and dramatically than do the floaters that people experience for much of their lifetime.

Khawly JA, Retinal detachment may be treated with a variety of surgical techniques, which aim to close any retinal tears or holes, reduce vitreous traction, and reattach the retina to provide permanent adhesion between the retina and retinal pigment epithelium. We review the literature related to the management of this disease. Haimann MH, Aaberg TM, Gass JD, Silicone Study Report 2. Sources of funding: none reported, The authors thank Steven A. 12.

Retinal detachment: diagnosis and management. In this procedure, called pneumatic retinopexy (RET-ih-no-pek-see), the surgeon injects a bubble of air or gas into the center part of the eye (the vitreous cavity). Cox MS. In cases where severe photophobia, periorbital edema, or opacity (e.g., cataract, intraocular blood) preclude ophthalmoscopy, ophthalmic ultrasonography is superior to magnetic resonance imaging and computed tomography for revealing occult retinal detachment (Figure 3). Within one week, sooner if the floaters worsen. Invest Ophthalmol Vis Sci. Foos RY, You may need to hold your head in a certain position for up to several days to keep the bubble in the proper position. Injecting air or gas into your eye. Freeman HM, Hartz AJ, Garretson BR, Hainsworth DP, During vitrectomy, the vitreous is removed from the eye and is replaced Your doctor also uses cryopexy during the procedure to repair the retinal break. Campochiaro PA. Wang Q, Retinal detachment. As persons age, this macromolecular network begins to liquefy and collapse, the vitreous shrinks, and vitreo-retinal traction develops.3 Eventually, the vitreous partly separates from the retinal surface, which is known as posterior vitreous detachment (Figure 2b). Cause. Myopia, or nearsightedness, is another leading risk factor for retinal detachment.9 In most patients with moderate or severe myopia, the axial (anteroposterior) length of the eye is greater, resulting in an egg-shaped globe. Byer NE. Bernth-Petersen P, Machemer R, The cumulative probability of RD is estimated at 0.27% during the first year after cataract surgery, and it continues to rise over time in a nearly linear manner to 1.79% at 20 years (Ophthalmology. Williams DF, A careful history helps to distinguish retinal detachment from other conditions with similar symptoms (Table 3).
