Retinitis pigmentosa is a genetic disease with a long process of development. Occurance of the color on the retina may prevent the visible cells obtaining and transferring images. And in the beginning of this illness, the victim can not see clearly, but is going to be blind at last. There are some symptoms of retinitis pigmentosa that you must bear in mind.
1. Night blindness. It is the first symptom of this illness and it often starts with kids or adolescents before some changes happens to the fundus. With increasing age, the condition will probably be more and more serious.
2. Dark adaption. The first cone cell's function remains normal while the rod function lessens. The curvature of the final rod threshold won't increase, causing constricting dissimilarities between light and color. Later, the rod cell loses its function, and the cone cells even boosts the threshold, creating a high single-phase curve.
3. Eye sight and central vision. Earlier stage has circinate dark points, lesion location and also the equator line. Consequently, annular dark points towards the central and peripheral eye sight gradually widened from tube. Central eye sight is normal or near normal during the early time, however lessens as the development of the disease. At last, it will cause total blindness.
4. Visual electrophysiology. ERG doesn't have responses; specifically, B wave's vanishing is the common change of this problem. That change often takes place at the start of the fundus. EOG LP / DT was drastically decreased or extinguished in the old times, even when such changes ( dark adaptation) are certainly not yet clear, it will be currently identified. As a result, diagnosis of the sickness EOG is more sensitive compared to ERG.
5. Color vision. The majorities of sufferers have normal color vision in childhood and later begin to prove to be an exception. A typical change is the blue blindness, the red and green ones get less obstacles.
