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.

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.
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].
Both methods create points of adhesion surrounding the retinal breaks to prevent the flow of fluid (see Figure 2).
This represents a visual field defect arising due to the retinal detachment and one can be certain that the location of the retinal break is in the opposite quadrant to the location of the curtain.
If the most likely diagnosis is PVD, and in particular if there is pigment in the vitreous, or haemorrhage in the absence of diabetes or other vascular signs, then a methodical examination of the retinal periphery must be carried out to locate any retinal breaks.
The symptoms of a retinal break or detachment should be described and the patient told to seek advice immediately if they should occur.
A tractional retinal detachment occurs without a retinal break.
Remember that few symptoms may mean serious pathology, and so any sudden change in floaters may indicate an acute PVD which may, in up to 10% of cases, be associated with a retinal break.
9) The presence of pigment in the vitreous is a sign that a retinal break may have occurred--70% of patients with acute hemorrhagic PVDs have tears compared with only a 2-4% prevalence in those without haemorrhage.
This patient was treated for proliferative vitreoretinopathy due to retinal breaks.
I would select this option for this patient because this specific detachment is well-suited to pneumatic retinopexy by virtue of the retinal breaks being located close together in the superior retina, which is the easiest location to treat with an intraocular gas bubble.
IRIDEX will immediately begin distribution of Innovatech's Illuminating endo ocular probes (Straight and Angled, 20 gauge) and Adjustable & Intuitive (20 and 25 gauge) for endophotocoagulation for the treatment of diabetic retinopathy, retinal breaks and detachments, and neovascular glaucoma.
