A detached retina lacks oxygen, which causes cells in the area to die.
This leads to loss of vision, which is gradual in nature & ultimately results in permanent blindness.
Repair is needed to prevent this permanent vision loss
The treatment modality (which ranges from Cryotherapy
& Laser photocoagulation to Pneumatic retinopexy & Vitrectomy
) is decided by the Ophthalmologist after a proper fundus examination & ruling out the risk factors for recurrence like Diabetes (Diabetic retinopathy
(Hypertensive retinopathy), High degree of myopia, Increased intra-occular pressure, etc.
So, it is advisable to get a corrective operation before any permanent damage occurs.
Wishing you a good health.
