Uncover what will cause retinitis pigmentosa
Retinitis pigmentosa is a hereditary disease with a long process of development. The formation of the color on the retina prevents the visual cells receiving and transferring images. And at the beginning of this sickness, the person can’t 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’s the first sign of this disease and it often begins with children or adolescents before some changes appear in the fundus. With growing age, the disease will probably be increasingly more serious.
2. Dark adaption. The first cone cell’s function is still normal while the rod function decreases. The curve of the final rod threshold won’t increase, leading to constricting variances between light and color. Later, the rod cell will lose its function, and the cone cells also boosts the threshold, forming a high single-phase curve.
3. Vision and central vision. Earlier stage has annular dark points, lesion location and the equator line. Subsequently, ringed dark points towards the central and peripheral eyesight steadily widened from tube. Central eyesight is typical or near normal during the early time, but reduces as the development of the disease. Finally, it will result in total blindness.
4. Visual electrophysiology. ERG has no responses; specifically, B wave’s vanishing is the common change of the diseases. That change usually occurs early in the fundus. EOG LP / DT was considerably decreased or put out in the past, even if this kind of changes ( dark adaptation) are certainly not yet clear, it will likely be currently identified. As a result, diagnosis of the sickness EOG is more sensitive than the ERG.
5. Color vision. The majorities of sufferers have normal color vision in childhood and later start to prove to be an exception. A typical change is the blue loss of sight, the red and green ones get less obstacles.
