“…A review of the existing literature [6][7][8][9][10][11][12][13][14] reveals that the ophthalmoscopic appearance and clinical course in our patients are similar to those seen in solar or welder's maculopathy, both of which are characterized by a photochemical type of damage to the outer retina. We have shown that they also have similar OCT characteristics both in acute and chronic stages, suggesting that they may share the same putative phototoxic etiology.…”

Background and Objectives: Photic maculopathy resulting from laser-induced plasma flash has been rarely reported, and the corresponding mechanism of the injury is still unclear. We present a case series of three patients with bilateral macular injuries produced by exposure to the plasma radiation from femtosecond laser tightly focusing. Study Design/Materials and Methods: Funduscopic findings were accompanied mainly by optical coherence tomography (OCT) investigation of the macula during the follow-up period. Results: All patients shared similar clinical symptoms soon after the initial injury, including reduced visual acuity and central scotomas. It was acutely characterized by foveolar yellowish faceted lesions upon fundus examination. The main OCT finding in the acute stage was a hyper-reflective area involving all foveolar retinal layers without retinal edema. Repeat OCT evaluation during the latter stages revealed that the retinal changes were reversible, but delineated mild pathology at the outer foveal retina. This retinal structural recovery was accompanied by improvements in visual acuity and central scotomas as well. Conclusions: Prolonged viewing of a plasma flash induced by a focused femtosecond laser without eye protection may produce persistent damage to the retina. We believe that a photochemical process similar to the mechanism of a solar burn or welder's maculopathy may cause retinal damage in this case series.

“…The pathophysiology and signs and symptoms are again similar to those seen with the other photic retinopathy conditions. 21 Our patient again denied any history of welding or exposure to lasers used in welding. Physicians should also note if one or both eyes are involved.…”

Purpose: Laser pointer retinopathy is a condition increasing in prevalence due to poor education of proper laser use at the childhood/teenage level and poor awareness of risks and complications of laser pointers among the adult population. Eye care physicians can serve as an important bridge among these populations to help increase awareness and promote and educate patients on the potentially damaging retinal effects associated with laser pointer viewing/exposure. Pathophysiology, signs and symptoms, multimodal imaging interpretation, and treatment management options of laser pointer retinopathy are reviewed through a case study. Background: A 19-year-old male presented to the eye clinic without any ocular or visual complaints for a routine eye examination. Fundus examination revealed yellow subfoveal scarring in the left eye and corresponding damage to the foveal ellipsoid zone on optical coherence tomography imaging. Amsler grid findings further confirmed metamorphopsia that was present only in the left eye. Further questioning determined the foveal damage to be laser pointer retinopathy secondary to extended laser pointer viewing. Conclusions: Laser pointer retinopathy is an increasingly prevalent retinal finding in younger populations. In most cases vision loss slowly improves with time, but the retinal damage has often been reported to be irreversible. Considering this information, it is imperative for optometrists to educate school staff, parents and children of the permanent ocular damage that can occur with laser pointer viewing and promote safe practices.

“…A much more frequent observation of ocular injury associated with welding arc use is photoelectric keratitis, often referred as "weld-erʼs eye" or "welderʼs flash" after unprotected exposure against emission in the ultraviolet spectrum, which is absorbed by the cornea and conjunctiva. Depending on the spectral range transmitted to the eye, either photoelectric keratitis or welding arc maculopathy or both together may develop [7]. Recent progress in posterior eye segment imaging has led to a precise characterization of typical outer retinal findings in welding arc maculopathy.…”
