What Researchers Did
Researchers presented two case reports of young coral fishers who developed progressive nearsightedness and nuclear cataracts.
What They Found
The two patients experienced progressive nearsightedness (myopisation) and nuclear cataracts. The study notes that index myopia and nuclear cataracts are common eye changes linked to increased oxygen pressure, which can occur during diving.
Canadian Relevance
While this study was not conducted in Canada, it discusses ocular alterations in divers, a group that includes many Canadians. The abstract mentions decompression syndrome, a Health Canada-recognised indication for hyperbaric oxygen therapy, as a risk for divers.
Study Limitations
This study is limited as it only presents two case reports, which may not represent the broader diving population.
