Assuming that vision is intact and decoding is rapid, fluent and not creating a drain on cognitive resources, having vocabulary adequate to the text and familiarity with relevant background information has a huge impact on reading comprehension. Familiarity with the formal structure of the text can also be helpful if relevant background knowledge is less than optimal. So just teaching about different types of writing and how they are organized and working on building vocabulary can really do a lot to improve comprehension.
