Official report finds eyewash inside retina (8)
I believe the answer is:
bulletin
'official report' is the definition.
(a news report)
'eyewash inside retina' is the wordplay.
'eyewash' becomes 'bull' (I can't justify this - if you can you should believe this answer much more).
'inside' indicates the central letters.
The middle of 'retina' is 'etin'.
'bull'+'etin'='BULLETIN'
'finds' acts as a link.
Can you help me to learn more?
(Other definitions for bulletin that I've seen before include "Short statement on the news as it happens" , "Short and regular up-date" , "Brief report issued to the public" , "Newsflash" , "Blue lint (anag.)" .)
