  • ACTLVATED LYMPHOCYTES IN EPI'RETINAL AND SUBRETINAL MEMBRANES

    PURPOSE: To investigate the activation and immune respones of lymphocytes in epiretinal membranes (ERMs)and subretinaI membranes (SRMs). METHODS: A panel of morioclonal antibodies against CD23 (activated B cell), CD25 (activated T cell), CD68(macrophages) and HLA-DR (human leukocyte antigen II antigen)were used for the study of 20 specimens of ERMs from 20 patients with proliferative vitreoretinopathy (PVR),traumatic PVR and secondary traction retinal detachment,and 2 SRMs from PVR and traumatic PVR, with positive and negative reaction specimens as controls. RESULTS:Four cases of ERMs were found to be CD23 and CD25 positive respectively,and one case of SRMs to be CD23 and CD25 positive respectively. All the specimens of ERMs and SRMs revealed CD68 and HLA-DR positive in this series. CONCLUSIONS :There might be an aberrant immunoreaction mediated by T and B cells in the ERMs and the SRMs,and they might play an important role in the patbogenesis of PVR,traumatic PVR and secondary traction retinal detachments.

  • ULTRASTRUCTURAL OBSERVATION OF THE SUBRETINAL MEMBRANE

    We observed 12(35.3%) cases of subretinal membranes in 34 patients with long-standing retinal detachments with proliferative vitreoretinopathy. Transmission electron microscopy revealed that glial cells, retinal pigment epithelial cells and a great amount of collagen represented the basic cellular and substantial components in a subretinal membrane obtained by vitreous surgery.
