Rationale:
The aim of this study was to report a case of Down syndrome (DS) complicated with bilateral retinal detachment (RD) due to unusual retinal degeneration.
Patient Concerns:
A 9-year-old girl complained of bilateral visual disturbance during a follow-up examination for myopia and strabismus.
Diagnoses:
Slit-lamp examination revealed moderate posterior subcapsular cataract in both eyes. B-mode echography showed bilateral bullous RD; however, it was difficult to detect the causal retinal breaks due to poor mydriasis.
Interventions:
For treatment, the patient underwent bilateral lensectomy, vitrectomy, and silicone oil tamponade.
Outcomes:
Intraoperative findings revealed symmetrical retinal breaks and unusual caterpillar-like retinal degeneration on the upper temporal side of both eyes. Three months later, the patient underwent bilateral silicone oil removal and intraocular lens implantation.
Lessons:
In this case, the retinal degeneration was morphologically different from retinal lattice degeneration, thus suggesting that it might be involved in the onset of DS-related bilateral RD.
