The role of intraocular f luid polymerase chain reaction in the diagnosis, treatment and monitoring of cytomegalovirus retinitis

Abstract

Purpose. To study the possibilities of a new method of CMRR treatment in the prevention of irreversible blindness. Material and methods. 74 patients with cytomegalovirus retinitis, frolicking after hematopoietic stem cell transplantation. The first group (9 people, 15 eyes) consisted of children, whose treatment was carried out under ophthalmoscopic control. The second group (65 people, 114 eyes) consisted of children in whom the control of the effectiveness of treatment was carried out using PCR of aqueous humor in real time. Results. In the first group, retinal detachment was diagnosed in three out of fifteen eyes, accounting for 20%. In the second group, the incidence of retinal detachment was 3.5% of 114 eyes. Among patients receiving treatment under ophthalmoscopic control, CMRR relapses were detected in 5 cases, which amounted to 33.3%. In children, whose treatment was controlled by intraocular fluid PCR, relapses were diagnosed in 22 cases, which amounted to 19.29%. Conclusions. Intravitreal administration of antiviral drugs under the control of polymerase chain reaction is a more effective method of treating cytomegalovirus retinitis than intravitreal administration under ophthalmoscopic control. Key words: cytomegalovirus retinitis, intraocular fluid polymerase chain reaction.
