Stalagmite-like pre-retinal deposits in the optical coherence tomography of two vitrectomy patients with panuveitis.

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.

Depósitos prerretinianos tipo estalagmita en la tomografía de coherencia óptica de dos pacientes vitrectomizados con panuveítis / Stalagmite-like pre-retinal deposits in the optical coherence tomography of two vitrectomy patients with panuveitis

Se presentan los casos de dos pacientes con panuveítis que, tras ser vitrectomizados, presentaron en la tomografía de coherencia óptica (OCT), depósitos prerretinianos inusuales en forma de estalagmitas hiperreflectivas, multifocales y de patrón perivascular.Caso 1: Varón de 51 años con panuveítis en el ojo derecho (OD). Tras una vitrectomía diagnóstico-terapéutica, la OCT evidenció depósitos prerretinianos tipo estalagmitas, sin una etiología clara y persistencia de los depósitos.Caso 2: Mujer de 76 años con panuveítis del OD. Tras una cirugía combinada de catarata y pelado de membrana epirretiniana, la OCT reveló depósitos prerretinianos tipo estalagmitas. La analítica reportó títulos IgG elevados para toxoplasma. Se prescribió claritromicina y corticoide con desaparición progresiva de los depósitos prerretinianos.Los depósitos prerretinianos tipo estalagmitas son un signo tomográfico poco común de los procesos uveíticos posteriores, parecen correlacionarse con la actividad inflamatoria, aunque sin un claro mecanismo y sin una etiología en particular.
