[Leukokoria. Diagnosis and treatment]

Is to evaluate the importance of the imaging tests when the posterior segments of the eye cannot be visualized due the opaque ocular media.

The paper presents 50 patients with unilateral or bilateral leukokoria treated în the University Eye Hospital from Cluj-Napoca. The parameters who had been watched were: the visual acuity, ultrasonography of the eye, and the management of the lesions associated with leukokoria. The ultrasonography was indicated for the diagnosis of the conditions associated with leukokoria, using a transducer of 7.5 MHz.

The conditions associated with leukokoria were: intraocular tumors în 8% of cases; congenital cataract în 24% of cases; persistent hyperplastic primary vitreous în 2% of cases; complicate or pathologic cataract în 27% of cases; retinopathy of prematurity în 6% of cases; vitreous opacities în 33% of cases. In 30% of cases ultrasonography of the eye was normal. Echography is also important for the differential diagnosis of secondary retinal detachment. We found exudative retinal detachment în 20% of cases; în 28% of cases there was a tumor retinal detachment, în 44% a tractional retinal detachment, and în 8% a posterior vitreous detachment. The performed management was represented by: enucleation în 12% of cases; EEC în 21% of cases; EEC + sinechiolisis în 11% of cases; sinechiolisis în 2% of cases; vitrectomy în 11% of cases; evisceration în 6% of cases; medical treatment în 20% of cases.

Ultrasonography is an important imaging test for the diagnosis of the conditions associated with leukokoria. Taking into account echographic results the adequate treatment of the eye lesions can be established.
