[Role of lactate dehydrogenase (LDH) level in the aqueous humor in the diagnosis of retinoblastoma (RB)].
In spite of the progress of the imagery in ophthalmology, the retinoblastoma remains in some particular cases, difficult to make. Moreover, the therapy sanction is often heavy. The lactate dehydrogenase (LDH) dosage in aqueous humor is an invasive technique conceivable when there are diagnosis problems particularly in retino-blastoma of old children and in affections simulating retino-blastoma. The purpose of this work is to lay out three observations where the LDH dosage enabled to keep the retinoblastoma diagnosis in one 8-year old child and eliminate it in two children having pseudoglioma with spontaneous evolution allowing to confirm the non-tumoral nature of the affection. Thus, the technique of LDH dosage has been reliable for the 3 cases which we have introduced. The authors compare the reliability of the different cytochemical techniques during the retinoblastoma diagnosis.
