Ruptured internal limiting membrane associated with blunt trauma revealed by indocyanine green staining

Abstract

Purpose: Description of cases of traumatic macular hole that appeared concomitant with a ruptured internal limiting membrane (ILM) that was apparent during vitrectomy only after staining with indocyanine green (ICG).

Methods: Vitrectomy with ILM peeling was performed on a 20-year-old man and a 13-year-old boy for treatment of traumatic macular holes.

Results: During vitrectomy, the ILM was found to be ruptured along the area of an identified macular hole only after ICG staining. After the vitrectomy, the macular holes were closed and visual acuity improved. However, visual field defect associated with apparent inner-layer retinal damage remained.

Conclusion: Blunt trauma can cause severe inner-layer retinal damage with rupture of the ILM as well as frank macular hole formation and choroidal rupture.
