What happens if left undiagnosed???
The changes initially do not have any symptoms. The patients may have normal vision. This leads to delayed diagnosis of the disease.
If left undiagnosed, they may develop sudden loss or gradual loss of vision which in some cases is irreversible.
Hence, Diabetic retinopathy screening is important.
