Retinopathy of Prematurity (ROP) Lawsuits: NY NICU Negligence

What Is Retinopathy of Prematurity (ROP)?

Retinopathy of Prematurity (ROP) is an eye disease that affects premature infants — particularly those born very early (before 31 weeks gestation) or with very low birth weight (under 1,500 grams / 3.3 pounds). ROP occurs when the blood vessels in the retina (the light-sensitive tissue at the back of the eye) develop abnormally.

In normal development, retinal blood vessels grow from the center of the retina outward — completing their growth around the time of full-term birth. In premature infants, this growth is interrupted — and when it resumes, it can grow abnormally, causing ROP.

ROP progresses through stages: - Stage 1: Mildly abnormal blood vessel growth. Usually resolves without treatment. - Stage 2: Moderately abnormal blood vessel growth. Usually resolves without treatment. - Stage 3: Severely abnormal blood vessel growth. The vessels grow toward the center of the eye rather than along the retina. May require treatment. - Stage 4: Partial retinal detachment. Requires treatment. - Stage 5: Complete retinal detachment. Causes permanent blindness. Even with treatment, visual outcomes are poor.

In addition to stages, ROP is classified by zones (which part of the retina is affected) and the presence of "plus disease" (abnormal blood vessel dilation and tortuosity — indicating aggressive, rapidly progressing ROP that requires urgent treatment).

How ROP Causes Blindness

ROP causes blindness through a cascade of events:

1. Abnormal blood vessel growth: The retinal blood vessels grow abnormally — toward the center of the eye rather than along the retina.

2. Fibrovascular proliferation: Scar tissue forms along with the abnormal blood vessels.

3. Traction on the retina: The scar tissue contracts — pulling on the retina and causing it to detach from the back of the eye.

4. Retinal detachment: The retina peels away from the back of the eye — cutting off its blood supply and causing permanent vision loss. Retinal detachment in ROP is often bilateral (affecting both eyes) — causing total blindness.

5. Permanent blindness: Once the retina detaches, the vision loss is usually permanent and irreversible — even with surgical treatment. This is why early detection and treatment of ROP — before retinal detachment occurs — is absolutely critical.

The Standard of Care for ROP Screening

The standard of care for ROP screening is established by the American Academy of Pediatrics (AAP), the American Academy of Ophthalmology (AAO), and the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). Key elements include:

1. Screening criteria: All infants born at ≤30 weeks gestational age OR with birth weight ≤1,500 grams should be screened for ROP. Some infants with higher birth weight or gestational age who have an unstable clinical course may also require screening.

2. Initial screening timing: The first ROP examination should occur at 4 weeks (31 weeks postmenstrual age, whichever is later) — or earlier if clinically indicated.

3. Follow-up examinations: Based on the findings, follow-up examinations are scheduled at 1-2 week intervals (or more frequently for aggressive ROP). The standard of care requires close follow-up until the ROP resolves or requires treatment.

4. Qualified examiner: ROP examinations must be performed by a qualified ophthalmologist — typically a pediatric ophthalmologist or retina specialist — with experience in ROP screening.

5. Proper examination technique: Using pupillary dilation, scleral depression, and indirect ophthalmoscopy to visualize the entire retina — including the peripheral retina where ROP often develops.

6. Documentation: Documenting the findings of each examination — including the stage, zone, and presence of plus disease — in the medical record.

7. Timely treatment: When ROP reaches treatment criteria (Type 1 ROP or worse), treatment should be initiated within 72 hours — as delays can allow progression to retinal detachment.

When ROP Negligence Constitutes Malpractice

ROP negligence constitutes medical malpractice when:

• Failure to screen: Not screening an at-risk premature infant (born ≤30 weeks or ≤1,500 grams) for ROP. This is a clear deviation from the standard of care.
• Delayed initial screening: Not performing the first ROP examination at the appropriate time (4 weeks of age or 31 weeks postmenstrual age, whichever is later).
• Failure to follow up: Not scheduling or performing follow-up examinations at the recommended intervals — allowing ROP to progress undetected.
• Failure to recognize ROP: The ophthalmologist fails to recognize ROP on examination — or misclassifies the stage, zone, or plus disease — leading to inadequate follow-up or treatment.
• Failure to treat at the appropriate stage: Not initiating treatment when ROP reaches treatment criteria (Type 1 ROP) — allowing it to progress to retinal detachment.
• Delayed treatment: Not initiating treatment within 72 hours of reaching treatment criteria — delays allow ROP to progress.
• Inadequate documentation: Not documenting the findings — making it impossible to track ROP progression or justify treatment decisions.
• Failure to transfer: If the hospital does not have qualified ROP screening capabilities, failing to transfer the infant to a facility that does — or failing to bring in a qualified ophthalmologist for screening.
• Failure to communicate: Not communicating ROP findings to the neonatologist, parents, and follow-up ophthalmologist — leading to gaps in care.

Risk Factors for ROP

While prematurity and low birth weight are the primary risk factors for ROP, other factors can increase the risk:

• Gestational age: The earlier the gestational age, the higher the risk. Infants born before 28 weeks are at particularly high risk.
• Birth weight: The lower the birth weight, the higher the risk. Infants under 1,000 grams are at particularly high risk.
• Oxygen therapy: Both too much and too little oxygen can contribute to ROP. Careful oxygen management is critical — fluctuations in oxygen levels are particularly harmful.
• Blood transfusions: May contribute to ROP by affecting oxygen-carrying capacity.
• Infection: Sepsis and other infections may increase the risk of ROP. [Link to: /medical-malpractice/sepsis-malpractice]
• Unstable clinical course: Infants with complicated medical courses — including respiratory distress, intraventricular hemorrhage, or other complications — may be at higher risk.

Treatment of ROP: Laser Therapy and Anti-VEGF Injections

When ROP reaches treatment criteria, treatment should be initiated within 72 hours. Treatment options include:

1. Laser photocoagulation therapy: The standard treatment for ROP. Laser is applied to the peripheral retina (the avascular zone) — to stop the abnormal blood vessel growth. This is typically performed under sedation or anesthesia — and may require transfer to a specialized facility.

2. Anti-VEGF injections: Injections of anti-vascular endothelial growth factor (anti-VEGF) medications (like bevacizumab/Avastin) into the eye — to stop abnormal blood vessel growth. This is increasingly used — particularly for Zone 1 ROP (affecting the central retina).

3. Vitreoretinal surgery: For ROP that has progressed to retinal detachment (Stages 4 and 5) — surgery (vitrectomy, scleral buckling) may be performed — but outcomes are poor, and vision is often permanently lost.

The goal of treatment is to prevent progression to retinal detachment and blindness — which is why early detection and treatment are critical. [Link to: /surgical-errors/eye-surgery-malpractice]

Consequences of Untreated ROP

When ROP is not detected and treated in time, the consequences are devastating:

• Permanent blindness: The most severe consequence. Once the retina detaches, vision loss is usually permanent and irreversible — even with surgical treatment. ROP blindness is typically bilateral (affecting both eyes).
• Severe visual impairment: Even without total blindness, ROP can cause severe visual impairment — including loss of peripheral vision, macular dragging, and retinal folds.
• Strabismus (misalignment of the eyes): ROP can cause strabismus — which may require surgery.
• Amblyopia (lazy eye): Reduced vision in one or both eyes due to abnormal visual development.
• Myopia (nearsightedness): Severe nearsightedness is common in ROP survivors.
• Lifetime consequences: Blindness or severe visual impairment in a child has lifelong consequences — affecting education, independence, employment, and quality of life. The cost of care, assistive technology, and support services over a lifetime is enormous.

Proving Causation in ROP Cases

Proving that ROP negligence caused blindness requires establishing:

1. The standard of care was breached: Expert testimony from a pediatric ophthalmologist — that the infant should have been screened, that ROP was missed or misclassified, that follow-up was inadequate, or that treatment was delayed.

2. The breach caused the blindness: Expert testimony that if the ROP had been detected and treated at the appropriate time, the retinal detachment and blindness would not have occurred — or would have been less severe.

3. The infant suffered damages: Including blindness or visual impairment, future medical expenses, cost of assistive technology and support services, loss of earning capacity, and pain and suffering.

The defense may argue that the ROP was particularly aggressive, that the outcome was inevitable, or that the parents contributed to the delay (by missing follow-up appointments). Expert testimony is required to counter these arguments — and to show that the standard of care was breached and that the breach caused the blindness.

New York Statute of Limitations

For ROP cases involving infants, the infancy toll (CPLR § 208) applies — pausing the statute of limitations until the child reaches age 18. The child then has until their 20th birthday (18 + 2.5 years) to file a claim. However, parents' claims for economic damages (medical expenses) must be filed within the standard 2.5-year statute and are NOT tolled during the child's minority.

For municipal hospital claims (NYC Health + Hospitals NICUs — including Bellevue, Elmhurst, Lincoln, Kings County, etc.), a Notice of Claim must be filed within 90 days — and this deadline is NOT tolled during the child's minority. This means parents must act quickly — even though the child has until age 20.
