ABSTRACT
A 63-year old man, with a large central vitreous floater, underwent a Nd:YAG laser posterior hyaloidotomy. Although the vitreous floater disappeared from the central optical axis, visual acuity did not improve. Microperimetry performed with the SLO revealed an absolute scotoma, which corresponded well in shape and dimension with the original vitreous floater. This finding suggests that a fragment of the neurosensory retina became detached together with the internal limiting membrane in the process of the vitreous collapse.

The need of medical treatment after photorefractive surgery has been studied by reviewing the literature on the subject and comparing their conclusions with our clinical experience. Considering the pre-operative and immediate post-operative medical treatment, there is a large consensus since the aim is treatment of pain and prevention of superinfection. The post-operative considerations for medical treatment are more controversial and can be considered as to be useful or possibly useful.
