Eight years have passed since the first English edition in 2011 and the topic of this textbook has lost none of its clinical significance. The coexistence of a dry eye can severely affect glaucoma patients in their daily lives. The associated consequence is reduced adherence in the use of antiglaucomatous eye drops, which represents a significant risk factor for the progression of glaucomatous optic neuropathy.
In this respect, this complex interplay between glaucoma disease and dry eye is very important in practical everyday life. Sometimes it is not easy to get both diseases under control. The present new edition should help to understand this problem a bit better and to provide the affected patients as optimally as possible.
