Brief Summary

Retinal detachment occurs when fluid separates the retina (a thin, light sensing tissue) from its usual attachment at the back of the eye. If detached, these retinal cells lose their normal blood supply and begin to die, which is the primary cause of vision loss in retinal detachment. The 'macula' refers to the very centre of the retina, with the highest density of retinal cells, most responsible for vision. Significant vision loss occurs when this part of the retina becomes separated (termed a 'macula-off retinal detachment'). Typically, surgery is required to repair the retinal detachment. Supporting the health of retinal cells at the macula may prolong their survival after detachment and their recovery postoperatively. Recent evidence has shown that boosting our nicotinamide adenine dinucleotide (NAD+) levels may improve the health of these cells and prolong their survival if detached. Oral Nicotinamide Riboside (NR) is converted into NAD+, and while not studied for macula-off retinal detachments, has been safely used in a range of other conditions. This study is designed to help evaluate the safety and tolerability of NR to help preserve vision in people diagnosed with macula-off retinal detachment. This study drug is given as an oral supplement (tablet) at the time of retinal detachment diagnosis, and daily for 20 weeks thereafter. The drug aims to prolong survival of cells in the retina (and macula) and their recovery after surgery. The long-term goal of this treatment is to reduce loss of vision after retinal detachment. The researchers will compare NR to a placebo (a look-alike substance that contains no drug) to see if NR has a positive effect on photoreceptor survival and quality of vision postoperatively. NR has been approved by the Therapeutic Goods Administration in Australia for many purposes but has not been approved for use in retinal detachment treatment.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years old
  • Able to give informed consent and comply with all study visits and procedures.
  • Present within 10 days of macula-off retinal detachment (based on patient-reported history of loss of central vision)
  • Present to the hospital with a visual acuity of hand motion or better in the study eye
  • Have had previous cataract surgery in the study eye
  • Have clinical indication for standard retinal reattachment surgery by means of a pars plana vitrectomy and gas tamponade
  • In the opinion of the investigator, be able to safely undergo all study procedures.

You may not qualify if:

  • Any known significant ocular disease in the study eye (e.g., cornea opacity) which, in the opinion of the investigator, would preclude a visual acuity of at least 6/7.5 (20/25) following successful vitrectomy or limit adequate visibility of the retina.
  • Any other ocular pathology in the study eye requiring treatment with topical ophthalmic drops or intravitreal injection.
  • History of previous ocular surgery in the study eye other than uncomplicated cataract surgery with posterior chamber intraocular lens and intact posterior capsule or a refractive surgery (surgery must have occurred at least 3 months prior to the baseline visit).
  • Participation in other clinical trials or use of any other investigational drugs or devices within 3 months prior to study participation.
  • Females who are pregnant or lactating and women of childbearing potential.
  • Known retinopathy, known hepatic disease (or history of significant chronic liver disease), or known renal disease. Patients Participants with diabetes and no known retinopathy may be enrolled.
  • History of uncontrolled hypertension.
  • History of stroke, transient ischemic attack, or major cardiac surgery within 3 months prior to study, or current treatment for systemic infection.
  • Any ocular or systemic condition that in the opinion of the investigator could compromise the safety of the patientparticipant, or may interfere with the safety and tolerability assessments or study procedures of the trial.
