[Diagnostic aspects and frequency of retrocorneal precipitates in diagnosis of cytomegalovirus retinitis in the HIV+ patient].

Cytomegalovirus retinitis (CMV) is the most common ocular opportunistic infection seen in patients with acquired immune deficiency syndrome. The anterior segment is usually quiet or with minimal aqueous humour flare and cell reaction. Nevertheless, in this prospective study of 30 eyes with CMV retinitis, 22 (73%) had white, small and filamentous keratic precipitates (KPS) which seem to corroborate this inflammation. The positivity of the KPS depends upon the extent of CMV retinitis.
