Retinal and choroidal damage from long-term exposure to a laser pointer beam

ABSTRACT

Introduction: Laser pointers are devices that produce a weak laser beam of 630-680 nmwavelength and 1-5 mW power [Class II or III A laser]. These devices generally emit a red beam that is used by lecturers and teachers for presentations. Some children use pointers as toys and sometimes direct the beam to their own or others' eyes
