Treatment
Calcium and vitamin D3 intake from diet or supplementation are crucial in the ethiopathogenesis of this disease; therefore, the effective treatments should consist of non pharmacological methods (such as a modified diet with more calcium 1000–1500 mg/day and vitamin D3 intake of 600-800 IU/day, exercising, smoking cessation, and alcohol restriction), fall prevention, and individually chosen pharmacological intervention (antiresorptive  agent like bisphosphonate or estrogen replacement therapy in women). Given bone fracture (hip, vertebrae, and colles) is a devastating complication of osteoporosis, vitamin D3 combined with calcium are used as primary prevention, along with alendronate, residronate, strontium and zoledronic acid which have proven efficacy in primary and secondary hip fracture prevention. The Institute of Medicine recommends a daily allowance of 800 IU of Vitamin D for people 70 and over, to get to a level of serum 25-hydroxyvitamin D (25OHD) of at least 20 ng/ml (50 nmol/liter) in addition to a daily allowance of 1,200 mg of calcium.One systematic review of pharmacological agents from 2008 on postmenopausal woman age 65 found bisphosphonates to be more efficacious in improvement of bone marrow density and reduction of vertebral fractures compared to placebo. This systematic review also found that parathyroid hormone and estrogen/progesterone therapy had significant improvements in bone marrow density compared to placebo. In addition to bisphosphonates, pharmacological treatments for osteoporosis can include calcitonin, parathyroid hormone 1-34, hormone replacement therapy, and monoclonal antibody therapy.
There study had 2 objectives:

to assess the safety and tolerability of the AAV.REP1 vector
to observe the therapeutic benefit, or slowing of the retinal degeneration, of the gene therapy during the study and at a 24-month post-treatment time pointDespite retinal detachment caused by the injection, the study observed initial improved rod and cone function, warranting further study. In 2016, researchers were optimistic that the positive results of 32 choroideremia patients treated over four and a half years with gene therapy in four countries could be long-lasting. Preimplantation genetic diagnosis
For women who carry a mutation in the CHM gene, preimplantation genetic diagnosis can be used during the in-vitro fertilization process to select unaffected embryos to implant. This process call be applied to any monogenic disease. Other potential therapies
While choroideremia is an ideal candidate for gene therapy there are other potential therapies that could restore vision after it has been lost later in life. Foremost of these is stem cell therapy. A clinical trial published in 2014 found that a subretinal injection of human embryonic stem cells in patients with age-related macular degeneration and Stargardt disease was safe and improved vision in most patients. Out of 18 patients, vision improved in 10, improved or remained the same in 7, and decreased in 1 patient, while no improvement was seen in the untreated eyes. The study found "no evidence of adverse proliferation, rejection, or serious ocular or systemic safety issues related to the transplanted tissue."
