13.10 Paediatric Retinal Detachment
Pediatric retinal detachments are complex in part due to their characteristics. When compared to adults, they are more likely to present with worse initial visual acuity, chronic duration and the macula detached. Proliferative vitreoretinopathy (PVR) is more common, reported to be present in 20-60% of cases, partially due to chronicity as well as increased levels of inflammatory mediators. Various predisposing factors to these retinal detachments that must be elucidated with history, imaging and testing (Figure 13.10.1).
Retinal detachment repair is performed with general anesthesia monitored ideally by a pediatric anesthesiologist. Ancillary testing of both eyes as well as blood samples for genetic testing is facilitated at this time. In specific cases where repeated general anesthesia may be undesirable due to social challenges, or systemic morbidity, immediate bilateral surgery is an option.
Anatomical considerations of surgical landmarks must be taken into account. Exposure to the eye is of utmost importance, lateral canthotomy might be necessary for exposure. The sclerotomies are placed according to age and pathology (Table 13.10.1). Pediatric sclera tends to be very tough and trocar entry may be facilitated by holding adjacent sclera or Tenon’s capsule and providing counter traction. If there is a need to remove the lens, or there is concern for iatrogenic retinal breaks with pars plana or pars plicata entry, limbal approach is preferred. Of note, a short trocar system is available from DORC and is especially useful in baby eyes.
