Submacular hemorrhage is a serious problem that can cause devastating visual loss. It can occur due to choroidal neovascularization (CNV), retinal arterial macroaneurysms, and trauma. It is more common in patients on anticoagulants, particularly those on warfarin and clopidogrel. There is no formal consensus on the management of submacular hemorrhage, as it very difficult to perform clinical trials in this area.
"A tidal bore (or simply bore in context, or also aegir, eagre, or eygre) is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current.Search yourself for the meanings of ebb and flood tides.
"Bores occur in relatively few locations worldwide, usually in areas with a large tidal range (typically more than 6 metres (20 ft) between high and low water) and where incoming tides are funneled into a shallow, narrowing river or lake via a broad bay. The funnel-like shape not only increases the tidal range, but it can also decrease the duration of the flood tide, down to a point where the flood appears as a sudden increase in the water level. A tidal bore takes place during the flood tide and never during the ebb tide."
