Immune complexes in retinitis pigmentosa.
In a group of 46 patients with retinitis pigmentosa (RP) we studied the presence of circulating immune complexes (CIC) and the alterations in the complement system. Our results showed the presence of CIC in 43.5% of the patients studied, reduced levels of the complement components C3 and C4 (p less than 0.001), and of the haemolytic activity CH50 (p less than 0.001) when compared with a control...
متن کاملRetinitis pigmentosa.
Hereditary degenerations of the human retina are genetically heterogeneous, with well over 100 genes implicated so far. This Seminar focuses on the subset of diseases called retinitis pigmentosa, in which patients typically lose night vision in adolescence, side vision in young adulthood, and central vision in later life because of progressive loss of rod and cone photoreceptor cells. Measures ...
متن کاملPhotoaversion in retinitis pigmentosa.
Photoaversion, or light-induced interference with visual comfort and performance, has been a recognised but poorly documented symptom in retinitis pigmentosa (RP). We found that a majority of our RP patients complained of photoaversion even in the absence of significant cataract. RP patients had reduced contrast sensitivity relative to normal people, but the decrement in their visual performanc...
متن کاملRetinitis pigmentosa
Retinitis pigmentosa (RP) is an inherited retinal dystrophy caused by the loss of photoreceptors and characterized by retinal pigment deposits visible on fundus examination. Prevalence of non syndromic RP is approximately 1/4,000. The most common form of RP is a rod-cone dystrophy, in which the first symptom is night blindness, followed by the progressive loss in the peripheral visual field in ...
متن کاملCellular immune function of patients with retinitis pigmentosa.
Although initial investigations of peripheral blood lymphocytes (PBL) from patients with retinitis pigmentosa (RP) demonstrated a reduced percentage of Leu-4 positive (pan-T) lymphocytes, the authors recently determined that the absolute number of Leu-4 positive cells per milliliter of blood is normal. This investigation studied the production of the lymphokines gamma-interferon (gamma-IFN) and...
