[問] 請問有沒有眼科醫師呀!!這段話是甚麼意思?

The ability to perceive light, but not to accurately localize its position is recorded as
Light Perception (LP). A test of localization of light of perception of light
should be carried out in a semi-darkened room with the fellow eye tightly occluded.
A patient sees your hand moving with OD and sees light with OS but cannot localize it.
His vision is recorded as ______ V OD HM V OS LP

WHAT??
怎麼翻都怪怪的
或許也是我專有名詞(術語?)還沒讀那麼多....
翻起來就很不順
想請問有沒有這方面的高手能夠指點一下!
謝謝
