Two patients with panuveitis are presented in whom, after undergoing a vitrectomy, the optical coherence tomography (OCT) revealed some unusual pre-retinal hyper-reflective deposits with the shape of stalagmites, distributed in a multifocal and perivascular pattern. Case 1: 51-year-old male with panuveitis in the right eye. After diagnostic-therapeutic vitrectomy, OCT showed pre-retinal stalagmite-like deposits. There was no clear aetiology, and the deposits persisted over the time. Case 2: 76-year-old woman with panuveitis in the right eye. After a surgery for cataract-vitrectomy and epiretinal membrane peeling, OCT revealed pre-retinal stalagmite-like deposits. The analysis reported elevated Toxoplasma IgG titres. Clarithromycin and corticosteroid were prescribed, resulting in the disappearance of pre-retinal deposits. The stalagmite-like deposits are not a very common tomographic sign of a posterior uveitis process, but they seem to correlate with inflammatory activity. There does not seem to be a clear mechanism or a particular aetiology.
