Purpose:

To report a case of macular damage from a laser pointer.

Method:

A 17-year-old man had a visual acuity disturbance in the left eye after accidental laser pointer exposure to class IIIA green laser pointer of 650 nm wavelength and 5 mW power for few seconds.

Results:

The patient’s best-corrected visual acuity was 7/10, he was complaining of blurring vision in his left eye. He had one small pericentral scotomata. On his ophthalmological examination there was a hypopigmented grayish lesion in the fovea. Optic Coherence Tomography (OCT) revealed disruption of the retinal pigment epithelial (RPE) layer and inner segment-outer segment (IS-OS) layer in foveal region. Within 2 months, visual acuity improved to 9/10 and visual field returned to normal, but a subjective relative decrease in brightness of objects in left eye was apparent. RPE and IS-OS layer abnormality persisted.

Conclusions:

Laser pointers, commonly used for teaching and other purposes, may cause important macular damage if accidentally exposed direct to fovea. Although visual disturbances generally improves with time morphologically, this may result a foveal retinal pigment epithelial and IS-OS bant disturbance.
