Purpose:

To report a case of choroidal neovascularization secondary to an accidental macular injury by a Ti: Sapphire laser.

Methods:

Description of a choroidal neovascularization secondary to an accidental macular by
laser.

Results:

A 30-year-old man, physics professor, was examined 2 months after being accidently hit by a laser beam in his left eye. He complained of sudden vision loss and central scotoma after the laser accident, with stabilization of the vision thereafter. At presentation, showed best-corrected visual acuity of 20/60 in the left eye. Fundoscopy disclosed a slightly elevated foveal white-grayish lesion, surrounded by a discrete subretinal hemorrhage inferiorly. Fluorescein angiography demonstrated an early-phase hyperfluorescent foveal lesion with staining and a slightly leakage in the late phase, characterizing a fibrovascular  CNV. The optical coherence tomography (OCT) showed a discrete increase in retinal thickness and a subretinal fibrotic CNV with a mild macular edema. The patient was reexamined 1, 2 and 4 months later. Visual acuity remained stable during this follow up.

Conclusion:

CNV after laser injury is rare. To our knowledge, this is the first report of CNV after a Ti: Sapphire laser trauma. The evolution of this case suggests that CNV after an accidental laser injury, in a healthy macula of a young patient, could have a self-limited course and a relatively good prognosis.

Take-home message:

Although CNV after laser injury is rare, the evolution of this case suggests that CNV after an accidental laser injury, in a healthy macula of a young patient, could have a selflimited course and a relatively good prognosis.
