Retinopathy of prematurity (ROP)
Abnormal retinal neovascularisation in the preterm infant (oxygen/prematurity)
Overview
Abnormal vascular proliferation of the developing retina in PRETERM/low-birth-weight infants, driven by prematurity and oxygen exposure. Ranges from spontaneous regression to retinal detachment and blindness. Detected by SCREENING (eligible preterm infants are examined at set times); treated with laser/anti-VEGF for threshold disease. (Cross-references ophthalmology.)
Recognise
- Preterm/low-birth-weight infant (especially with significant oxygen exposure); asymptomatic — detected on SCREENING
- Staged by zone/extent; 'plus disease' (dilated tortuous vessels) signals activity
- Untreated severe disease → retinal detachment, blindness
Red flags
- Threshold/plus disease → treat (laser/anti-VEGF) to prevent detachment
- Retinal detachment
Differentials & how to tell them apart
Investigations
ROP SCREENING (indirect ophthalmoscopy) in eligible preterm infants per the national protocol; staged and zoned.
Management
Screening → laser/anti-VEGF for threshold disease
- 1Screen eligible preterm infants per protocol. Treat threshold/plus disease with laser or anti-VEGF to prevent progression.Gate: ROP is a SCREENING diagnosis (asymptomatic) — eligible preterm infants must be examined on schedule; careful oxygen targeting reduces incidence
- 2Treat threshold disease; ongoing ophthalmology follow-up (refractive error, late detachment). (See ophthalmology for retinal detail.)
Key points
Preterm + oxygen exposure → screen the retina (ROP). Asymptomatic — caught only by screening; treat threshold/plus disease with laser/anti-VEGF. Oxygen targeting prevents it.
Monitor & prognosis
Serial screening; post-treatment follow-up.
Often regresses; severe disease threatens sight.
