Hello It seems from the history that your daughter is diagnosed with retinitis pigmentosa. Retinitis pigmentosa is a disease affecting the rods and leads to gradula loss of peripheral vision and night vision. As of now there is no curative treatment for retinitis pigmentosa. But no need to worry as not all cases will lead to loss of vision. Only few cases will end in loss of vision. The treatment options available as of now are to prevent progression of vision loss by using vitamin A supplements and use of carbonic anhydrase inhibitors in cases of macular edema. The trials of using retinal chip implants are under research and may be shortly available for definitive treatment of retinitis pigmentosa. Thank you
