[Sub-internal limiting membrane haemorrhage--causes, diagnosis and treatment]

The purpose of this study was to present cases of patients with massive sub-internal limiting membrane haemorrhage, who were treated with vitrectomy.

We present 2 patients with sub-internal limiting membrane haemorrhages diagnosed clinically, seen in spectral optical coherence tomography and confirmed during vitrectomy with the internal limiting membrane peeling. Visual acuity and clinical manifestation in spectral optical coherence tomography were assessed before and after vitrectomy.

The haemorrhage was successfully removed from under the internal limiting membrane in both cases. Visual acuity improved and normal anatomical relationships were restored within the fovea in both patients as well.

Vitrectomy is a safe and effective method, offering fast improvement of visual acuity in patients with massive sub-internal limiting membrane haemorrhage.
