Retinal Detachment
What is Retinal Detachment？
Retinal detachment refers to the detachment of the photosensitive layer in the retina from the back of the eyeball. Unlike the cornea, the cornea is a thin film located in front of the eyeball. 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.
Cause
The causes of retinal detachment are divided into primary and secondary, and most retinal detachments are primary.
It is related to factors such as deep myopia and family inheritance. Other causes of retinal detachment include secondary eye injury, intraocular inflammation etc.
High Risk Group
- High refractive errors(eg over 600 diopters myopia)
- Severe Diabetic Retinopathy
- Fundus Inflammation
- Eye injuries
- Family inheritance
Symptoms
- Increase of floaters
- Flashes
- Dark or black vision
- The visual image is deformed and blocked
Treatment
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.
