Retinal detachment could cause permanent vision damage, and even lead to blindness. So, if you suddenly see a large number of floaters, flash light or darkness, you should contact your ophthalmologists immediately and receive eye examination and treatment as soon as possible. Those with serious myopia (more than 600 degrees), eye injury, fundus inflammation, severe diabetes and with family history are at high risk of retinal detachment. A regular comprehensive eye examination may help to early detect and prevent retinal detachment.
There are different situations of retinal detachment. If there are retinal cracks only, laser coagulation therapy could be used to avoid intravitreal aqueous influx into the cracks, and hence to avoid retinal detachment. However, if the retina has already been shed, ophthalmic surgery should be carried out as soon as possible to restore vision.
