New approaches to the diagnosis and management of laser eye injury

The emergence of high resolution optical coherence tomography (OCT) along with evidence showing beneficial effects of anti-inflammatory drugs for retinal edema and neovascularization suggests a rational plan for the diagnosis and management of patients with acute laser eye injury. We review the results of recent experiments we conducted to evaluate treatment of laser lesions followed by reports of two cases of acute laser eye injury with foveal involvement. The initial presentation of these cases was notable for the lack of significant abnormalities on fluorescein angiography whereas OCT readily disclosed the size and extent of retinal involvement from exposure to laser energy. Prompt referral of these cases resulted in rapid initiation of medical therapy which included a 10-14 day combined course of steroid and non-steroidal anti-inflammatory medication. An initial decrease in Snellen visual acuity of approximately two lines (20/25- to 20/30) was noted on presentation. In both cases, a measurable improvement of visual acuity was noted by two weeks post injury. The use of anti-inflammatory medication may enhance the initial recovery of vision and reduce the likelihood of longer term retinal complications from scarring and neovascularization.
