“…The mechanism of action of rhodopsin mainly occurs in two ways: the first due to a prolonged activation of rhodopsin as meta-rhodopsin, which leads to a reduction of the concentration of intracellular calcium, initiating apoptosis, and the second through the issuance of phototoxic substances such as retinal [8]. Histological examination immediately following light exposure reveals that photoreceptor cell damage begins at the apex of the photoreceptor outer segment and advances over time to include the entire outer segment [9-12].…”

Backgroundthe purpose of this study was to report a binocular photic retinal injury induced by plasma arc welding and the follow-up after treatment with vitamin supplements for a month. In our study, we used different diagnostic tools such as fluorescein angiography (FA), optical coherence tomography (OCT) and multifocal electroretinogram (mfERG).Case presentationin the first visit after five days from arc welding injury in the left eye (LE) the visual acuity was 0.9 and 1.0 in the right eye (RE). FA was normal in both eyes. OCT in the left eye showed normal profile and normal reflectivity and one month later, a hyperreflectivity appeared in the external limiting membrane (ELM). The mfERG signal in the LE was 102.30 nV/deg2 five days after the injury and 112.62 nV/deg2 after one month and in the RE respectively 142.70 nV/deg2 and 159.46 nV/deg2.Conclusionsin cases of retinal photo injury it is important for the ophthalmologist to evaluate tests such as OCT and the mfERG in the diagnosis and follow-up of the patient because the recovery of visual acuity cannot exclude the persistence of phototoxic damage charged to the complex inner-outer segment of photoreceptors.

Abstract. Multifocal electroretinography (mfERG) is an investigation that can simultaneously measure multiple electroretinographic responses at different retinal locations by cross-correlation techniques. mfERG therefore allows topographic mapping of retinal function in the central 40--50 of the retina. The strength of mfERG lies in its ability to provide objective assessment of the central retinal function at different retinal areas within a short duration of time. Since the introduction of mfERG in 1992, mfERG has been applied in a large variety of clinical settings. This article reviews the clinical applications of mfERG based on the currently available evidence. mfERG has been found to be useful in the assessment of localized retinal dysfunction caused by various acquired or hereditary retinal disorders. The use of mfERG also enabled clinicians to objectively monitor the treatment outcomes as the changes in visual functions might not be reflected by subjective methods of assessment. By changing the stimulus, recording, and analysis parameters, investigation of specific retinal electrophysiological components can be performed topographically. Further developments and consolidations of these parameters will likely broaden the use of mfERG in the clinical setting.

“…An arc welder emits at both ultraviolet and infrared visible light and the intense near ultraviolet emissions lead to maculopathy when prolonged light exposure causes damage to the photoreceptors, retinal pigment epithelium (RPE) and other layers. Acute presentation of phototoxic trauma includes de‐pigmentation of the RPE and oedematous greying of the macula, while there is secondary involvement of the other retinal layers 5 . Young apprentice welders are most at risk of this type of injury owing to vocational inexperience and clear ocular media 2 .…”

“…While the retinal changes associated with this type of maculopathy have been reported, 1,2,5–7 the functional vision problems have not been well documented and are underestimated owing to small scotoma and preservation of reasonable distance acuity. The clinical characteristics and the functional visual implications of a patient with phototoxic maculopathy from arc welding are described.…”
