Necessity of Retinopathy of Prematurity Examination?

Patient's question:

Premature infant born at 34 weeks, stayed in an incubator for 16 days, weighed 5 jin at discharge

Doctor's answer:

Diagnosed with retinopathy, possibly leading to blindness. Most premature infants with retinopathy can avoid blindness through early treatment, but due to insufficient awareness of retinopathy in premature infants among parents, many patients often miss the best treatment time.
