Hydrogen Gas Protects Premature Babies' Eyes from Blindness-Causing Disease

TL;DR

Inhaling hydrogen gas helps reduce damage and improve healing in the eyes of mice with a disease similar to one that causes blindness in premature babies, without affecting normal eye development.

Key Finding

Inhaling 3-4% hydrogen gas promoted normal retinal blood vessel regeneration while suppressing abnormal blood vessel growth and protecting eye support cells in mice with oxygen-induced retinopathy.

Summary

This study examined whether inhaling molecular hydrogen gas could help treat retinopathy of prematurity (ROP), a serious eye disease in premature infants that can cause blindness. Researchers exposed newborn mice to high oxygen levels to mimic ROP, then gave some mice hydrogen gas to breathe. The hydrogen treatment helped restore normal blood vessel growth in the retina while reducing abnormal blood vessel growth and protecting supporting cells in the eye, likely by reducing harmful molecules called free radicals.

Practical Takeaway

This is early-stage research conducted only in mice, not humans. While the results are promising and suggest hydrogen inhalation may eventually help treat retinopathy of prematurity, much more research—including human clinical trials—would be needed before this could become a treatment option. Parents of premature infants should continue following current medical recommendations and discuss any interest in hydrogen therapy with their eye specialist.

Abstract (excerpt)

Abstract Background Retinopathy of Prematurity (ROP) is a proliferative retinal vascular disease occurring in the retina of premature infants and is the main cause of childhood blindness. Nowadays anti-VEGF and retinal photocoagulation are mainstream treatments for ROP, but they develop a variety…
