Editor, We thank again Dr Grzybowski (2011a) for his concerns raised about our study on the potential role of a low cerebrospinal fluid pressure (CSF-P) in the pathogenesis of glaucoma. We also refer to our previous reply to a similar letter written by Dr Grzybowski (Grzybowski et al. 2011b; Ren et al. 2011a). Firstly, Dr Grzybowski stated in his letter that ‘As Ren et al. point out, a great deal of literature has shown little or no foundation for the idea that low cerebrospinal fluid (CSF) pressure is related to optic neuropathy’. The data provided by the study Dr Grzybowski refers to and the findings reported in the previous studies by Yablonski et al. (1979), Morgan et al. (1995), Berdahl et al. (2008a,b) and eventually by Ren et al. (2010) indeed suggested that a low CSF-P is involved in the pathogenesis of glaucoma. This has also clearly been stated in the article Dr Grzybowski refers to (Ren et al. 2011b).
