A case of photic retinal injury associated with exposure to plasma arc welding.

Choi SW, Chun KI, Lee SJ, Rah SH - Korean J Ophthalmol (2006)

Bottom Line: On his first visit, one day after performing plasma arc welding with protective gear at work, his best corrected vision was 0.7 for both eyes.Ophthalmic examination of the fundus showed a round yellow lesion with an approximate size of 300 micrometers superonasal to the fovea of both eyes.On his next visit, one month later, his vision had recovered to 1.0, his symptoms had improved, and the ophthalmoscopic examination of the fundus revealed that the round yellow spots had disappeared from both eyes.

ABSTRACT

Purpose: To report of photic retinopathy induced by plasma arc welding, and the OCT (optical coherence tomography) results of damaged retinal lesions.

Methods: We describe a case report of a 37-year-old male, working in the steel industry, who presented with central scotoma in both eyes.

Results: On his first visit, one day after performing plasma arc welding with protective gear at work, his best corrected vision was 0.7 for both eyes. Ophthalmic examination of the fundus showed a round yellow lesion with an approximate size of 300 micrometers superonasal to the fovea of both eyes. On his next visit, one month later, his vision had recovered to 1.0, his symptoms had improved, and the ophthalmoscopic examination of the fundus revealed that the round yellow spots had disappeared from both eyes.

Conclusions: To our knowledge, this is the first report of photic retinopathy induced by plasma arc welding, and the OCT (optical coherence tomography) results of damaged retinal lesions have not previously been reported. For these reasons, we report this case.

Figure 5: Ring-shaped paracentral hyperfluorescence appears simultaneously with a central halo in the early phase (white arrow, right eye).

Mentions: His best corrected vision was tested and was found to be 0.7 for both eyes, and no keratitis was observed. Fundus examination revealed the presence of a round yellow lesion about 300 micrometers in size superonasal to the fovea of both eyes (Fig. 1). Although the visual field test did not reveal any apparent signs of central scotoma, scotoma was observed in the central region using the Amsler grid test (Fig. 2). The lesion of the macula was scanned using OCT, and no abnormal signs were observed (Fig. 3). H-R-R plates (Hardy-Rand-Rittler plates) were used to test color vision and no abnormal signs were observed. On the same day, the patient was examined with fluorescein fundus angiography. In the early phase, ring-shaped paracentral hyperfluorescence appeared simultaneously with a central dark halo. In the late phase, the dark center of the lesion was surrounded by progressively increasing hyperfluorescence (Figs. 4, 5, 6, and 7).
