Accidental Nd:YAG laser-induced choroidal neovascularization

Lasers Surg Med. 2008 Apr;40(4):240-2. doi: 10.1002/lsm.20626.

Abstract

Background: There are few reports in the literature to describe the natural history of an occupational Nd:YAG laser-induced retinal injury.

Methods: The chronological response to a Nd:YAG laser-induced injury was studied in a 48-year-old male using the techniques of color fundus photography, fluorescein angiography and optical coherence tomography. When he developed choroidal neovascularization his response to photodynamic therapy with verteporfin was recorded.

Results: The patient initially developed a macular hole, which spontaneously closed. Three months after the injury a choroidal neovascular membrane developed. This stabilized after the use of photodynamic therapy.

Conclusions: Surgical closure of Nd:YAG induced macular holes should be delayed to allow spontaneous closure. Photodynamic therapy was successful in treating choroidal neovascularization in this case.
