Some Parameters of Immune Status in Children before and after Cataract Extraction with Intraocular Lens Implantation.
An immunological study was performed in 71 children aged 6-15 years old. Twenty seven of these 71 patients have undergone surgery for congenital cataract, 23 - for traumatic cataract aspiration-irrigation with a posterior chamber intraocular lens implantation and 21 - for secondary intraocular lens implantation. The number of peripheral blood active T lymphocytes, CD4(+), CD8(+), HLA DR(+) lymphocytes and antibody response to lens (alpha-crystalline) and retina (S-antigen) proteins were determined. Tissue specific antibodies were revealed in cases of both increased and decreased T-cellular immunity parameters. Sensibilization to S-antigen at the background of HLA DR(+) lymphocytes increase and a decrease in other parameters of immunity that may be regarded as the autoimmune status was the most unfavorable prognostic sign. In these cases even after atraumatic surgery the risk of postoperative inflammation was rather high with development of chronicity.
