  • Look Inside

We treated 28 patients with typical retinitis pigmentosa using hyperbaric oxygen therapy. Their ages ranged from 29 to 82 years, average 57 years. The patients were placed for one hour in a capsule containing 100% oxy-gen at 2 atomospheric pressure. The treatment was repeated for 20 consecutive days. The patients were followed up for 1 to 10 years, average 5.1±3.1 years. Log visual acuity averaged -0.99±0.87 before treatment, -0.61±0.76 (p <0.00001) one year after, and -0.11±1.1 (p=0.32) at the last observation. Critical fusion frequency (CCF) averaged 23.6±13 before treatment, 35.4±8.5 (p<0.00001) one year after, and 22.9±12 (p=0.76) at the last observation. Subjective symptoms improved in 79% of patients immediately after treatment and in 21% at the last observation. The findings show that hyperbaric oxygen therapy may not he effective for retinitis pigmentosa on a long-term basis.
