Abstract:
Exploratory pars plana vitrectomy (EPPV) made one quarter of injured eyes with no light perception (NLP) rescued. Previously, the clinical routine in making a decision of enucleation for injured eyes with NLP was based on preoperative evaluation. Such ideas, however, have altered with development of EPPV. Some extraordinary lesions can be explored in those moribund eyes during EPPV and dealt with newly developed techniques. This article reveals the pathological basis of traumatized NLP eyes and the advantages and effects of EPPV, and puts forward the concept that decision making of enucleation should be based on findings obtained during EPPV. (Chin J Ophthalmol, 2019, 55: 645-646).

Perspectives on Sensation and Perception
The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in...
