Insights
Exudative retinal detachment (ERD) is a rare complication of retinopathy of prematurity (ROP) laser treatment. Tailoring laser settings and adjusting postoperative care can lead to near-complete resolution of ERD.
Area of Science:
- Ophthalmology
- Neonatology
Background:
- Retinopathy of prematurity (ROP) is a leading cause of blindness in premature infants.
- Laser photocoagulation is a standard treatment for ROP, but can have complications.
- Exudative retinal detachment (ERD) is a rare but serious postoperative complication of ROP laser treatment.
Observation:
- A case of bilateral ERD occurred in a preterm infant following ROP laser photocoagulation.
- The infant received standard laser treatment with adjusted power due to absorption.
- Postoperative care included prednisolone acetate drops, which were later intensified.
Findings:
- Complete ERD developed one week after laser treatment.
- ERD resolved near-completely within eight weeks with modified postoperative management.
- The case highlights the importance of individualized laser settings and titration.
Implications:
- This case underscores the need for personalized laser parameters in ROP treatment, even with established protocols.
- Close monitoring and titration of laser power based on tissue response are crucial.
- Effective management of postoperative ERD is achievable with adjustments to standard care.
Abstract:
Exudative retinal detachment (ERD) can be a rare postoperative complication of laser photocoagulation surgery when used to treat type I retinopathy of prematurity (ROP). We present a case of bilateral ERD following ROP laser photocoagulation. A preterm male infant born at 24 weeks gestation and weighing 600 grams was diagnosed with stage 3/zone II/pre-plus ROP in both eyes. He was on oxygen therapy for 92 days due to chronic lung disease and was treated with laser photocoagulation at 40 weeks postmenstrual age. Initial laser settings (in use for over 15 years) were 300 mW power, 300 ms duration, and 300 ms intervals. Due to strong laser absorption, power was decreased to 250 mW for most of the procedure. He was prescribed prednisolone acetate drops four times per day for postoperative care. One week later, he developed complete ERD in both eyes. The patient was monitored in the neonatal intensive care unit (NICU) for three weeks and prednisolone acetate drops were increased to every two hours and tapered over one month. Complete resolution of ERD with residual peripheral exudate bilaterally was observed eight weeks after surgery. This case suggests that even after the settings of an ROP laser have been used safely for 15 years, it is important to tailor settings for each individual patient utilizing the least power and duration for laser application as possible. Furthermore, this case highlights the importance of titrating laser power in response to spot blanching throughout the procedure. However, near-complete resolution of post-ROP laser ERD is possible with minimal changes to standard postoperative management.
