ABLATIO RETINAE PDF

The images may show: folded membranes with subretinal space fluid which is usually hyperdense on CT the detachment is limited anteriorly by the ora serrata compared to the choroidal detachment that is not limited and extends beyond it posteriorly the detachment converges on the optic disc compared to the choroidal detachment that diverges at the disc Treatment and prognosis Treatment is varied and beyond the scope of this article, but in general terms requires reattachment of the retina using intraocular gas, lasers, cryotherapy or surgery. Intra-ocular silicone oil is also sometimes used. Improved prognosis and surgical outcomes are seen with macula-on retinal detachments where the fovea is still attached 5. Macula-off, or central retinal detachments have worse initial visual acuity and prognosis. Differential diagnosis posterior vitreous detachment References 1.

Ultrasound showing a retinal detachment [26] A physician using a "three-mirror glass" to diagnose retinal detachment Retinal detachment can be examined by fundus photography or ophthalmoscopy. Modern fundus photographs generally recreate considerably larger areas of the fundus than what can be seen at any one time with handheld ophthalmoscopes. Ultrasound has diagnostic accuracy similar to that of examination by an ophthalmologist. Retinal breaks are divided into three types — holes, tears and dialyses.
