Singapore (VNA) - The number of cases of diplopia – which causes a person to see double – with no known cause seen at the Singapore National Eye Centre (SNEC) is witnessing a rise, in line with the worldwide trend, according to an insider.
Commonly known as double vision, diplopia can occur when one eye is covered (monocular diplopia) or only when both eyes are open (binocular diplopia).
A survey of binocular diplopia cases at SNEC conducted earlier in 2024 showed there were 234 patients between 2011 and 2020, up from 15 patients from 2001 to 2010. From 2021 to 2023, there were already 76 patients. These patients are mostly adults.
Binocular diplopia is when you see double with both eyes open, and it disappears upon closing either eye, said senior consultant Yvonne Ling. It may be due to a neurological problem, or it may be due to too much screen time, especially on mobile phones, she said.
Such cases of binocular diplopia with no known cause used to be few and far between at SNEC, but they have risen in recent years, possibly due to excessive and uninterrupted screen time use on mobile phones, said Dr Ling, whose speciality is adult strabismus and paediatric ophthalmology./.
