detachment of the retina
Học thuậtThân thiện
Definition
Noun: A serious eye condition where the retina, the light-sensitive layer of tissue at the back of the eye, pulls away from its normal position. This separation from the underlying supportive layer (the choroid) disrupts the retina's blood supply and function, leading to vision impairment. It is a medical emergency typically treated with surgical procedures, including photocoagulation (using lasers to seal retinal tears).
Examples of Usage
- Early symptoms of detachment of the retina can include sudden flashes of light and floaters.
- The ophthalmologist confirmed the diagnosis was detachment of the retina and scheduled immediate surgery.
- Without prompt treatment, detachment of the retina can result in permanent vision loss.
Advanced Usage
- "to suffer a detachment of the retina": To experience this medical event.
- The boxer suffered a detachment of the retina after the powerful blow.
- "surgical repair of a detachment of the retina": Refers to the operative procedure to correct the condition.
- The success rate for surgical repair of a detachment of the retina is high if performed quickly.
