retinal break

A break in the continuity of the retina, usually caused by trauma to the eye. Detachment of the retina may follow the appearance of the break.

retinal break 

A full thickness opening in the neurosensory retina. It may be a hole, usually due to atrophy of the retina and often overlaid by an operculum; or a tear, horseshoe-shaped (U-shaped), round or slit-like, usually caused by posterior vitreous detachment in which the vitreous adheres to the retina and pulls it from the point of adherence during or just after an abrupt eye movement; or a giant retinal tear which involves 90º or more of the circumference of the globe and is commonly associated with Marfan's syndrome or Stickler's syndrome; or retinal dialysis which is usually the result of trauma. The patient may complain of photopsia, seeing floaters or flashes and some visual field defects and they may present with a vitreous haemorrhage. Management of retinal breaks includes localized laser photocoagulation (laser retinopexy) or cryopexy, a method of cryotherapy (freezing of the tissues causing local protein denaturation which leads to adhesion of the retina to the pigment epithelium), as the defect may lead to rhegmatogenous or tractional retinal detachment. See macular hole; retinal dialysis; retinoschisis; Shafer's sign.

Use of IVB as an adjunct to other treatment modalities has been mentioned in literature.4 In another study, it was highlighted that excessive laser photocoagulation done conservatively for management of ED can result in iatrogenic retinal breaks formation, adding to the chances of retinal detachment.10 Use of IVB can spare excessive laser treatment, thus reducing number of visits and chances of retinal detachment.
Multiple regression analysis was used to evaluate the correlation between the expression levels of hsa-miR-148a-3p and the independent variables such as the corrected pixels of the retinal break, the range of RD, and the time from onset from RRD to vitrectomy.
They have some important characteristics such as optical clarity, permanent retention and chemical inertness but they are also associated with many complications such as poor contact with retina due to the hydrophobic nature, cataract, oil in anterior chamber, less tamponade effect in case of inferior retinal breaks, irreversible cell damage, postoperative retinal detachment etc [3].
To evaluate the impact of these two surgical techniques on anatomic and visual recovery, only patients who met the following criteria were included in the analysis: the presence of RRD with retinal breaks associated with vitreous hemorrhage resulting from rupture of a peripheral retinal blood vessel and not obscuring the view of the fundus periphery (especially the retinal break region), optic disc and vascular structures (grade1- mild vitreous hemorrhage with visible fundus details).
If RD is secondary to retinal breaks outside the colobomatous area, it can be treated by scleral buckling; however, when the coloboma is etiologically responsible for RD5 management options are different6.
Treatment should only be performed in exceptional cases such as enlargement into the foveal area, posterior layer retinal breaks, schisis-detachment and progressive, frank, symptomatic RD.
With closed infusion, the retinal break(s) were localized, the eye was rotated in order to position the region of the retinal break as high as possible, and air infusion was started with a pressure of 30-35 mmHg.
Scleral buckle alleviate vitreous and retina traction and causes the margins of retinal break to come close to underlying retinal pigment epithelium.2
Study also aims to analyze characteristics of type of retinal breaks, other eye findings and etiological factors in pediatric RRD.
There is no association with retinal break or detachment.
lattice degeneration, a previous retinal break, and age-related retinoschisis.
On the other hand, in the ERM that occur after rhegmatogenous RD, the retinal pigment epithelial cells are thought to migrate to the vitreous cavity through the retinal break and settle on the retinal surface, forming the membrane [26].
