Background: AMD is becoming one of the leading causes of blindness in older adults. The prevalence rate of the wet form of AMD has been increasing due to the lack of selective therapeutic modalities. Current therapeutic interventions such as drugs targeting VEGF, and VEGF receptors, laser coagulants delivered unsuccessful clinical outcomes in AMD patients. Hence, the cost-effective anti-oxidant therapeutic interventions like molecular hydrogen to protect retinal pigment epithelium (RPE) by mitigating oxidative stress may deliver effective clinical outcomes in AMD patients.

Methods: Female patients with late-stage AMD of age above 70 years were chosen for this case report. The patients were administered QIAPI1©, a melanin precursor via sublingual route and the photographs were obtained for left and right eye to depict the efficacy of QIAPI1© against the wet form of AMD.

Results: The administration of QIAPI1© extensively mitigated yellow-colored drusen accumulations in the retina, retinal edema, exudates, and hemorrhages in the right eye, but the effect was minimal in the case of left eye; the overall drusen accumulation was lesser than the first consultation.

Conclusion: Current case report has concluded the intrinsic effect of melanin in producing the molecular hydrogen and chemical energy across the retinal tissues by dissociating water molecules and dissipating the drusen accumulations, retinal edema, and hemorrhages in AMD patients. Our preliminary study reported the usage of QIAPI1© as a prospective therapeutic modality to mitigate the oxidative stress-mediated pathophysiology of the wet form of AMD.

Keywords: AMD, melanin, QIAPI1©, drusen accumulations, retinal pigment epithelium, oxidative stress, molecular hydrogen.
