**4.7 Choice of tamponade**

In patients with vitreous or subhyaloid haemorrhage or tractional macular edema with no retinal breaks, a simple fluid air exchange would suffice in most cases. In TRD with no iatrogenic breaks, it is not required to drain the SRF using drainage retinotomy. A gas tamponade may suffice in such cases, as the SRF gets absorbed over a period of time gradually. In CRD or TRD with iatrogenic breaks, a gas or a silicon oil tamponade would be required.
