I'm helping a non-English speaker with his thesis, which involves many medical abbreviations–so many that, when they are used in a sentence, it doesn't read too well. For example:
The CH by ORA decreased and the average reduction in IOPg by ORA decreased in some patients but correlation existed between reduction of IOPg and CRF.
The full words are initially abbreviated in the introduction and there are a lot of sentences similar to this example.
Should I use the full words with abbreviation each time (e.g. Corneal Resistance factor [CRF]), or should I stick to abbreviations (e.g. CRF)?
