1. Apparent ocular findings obtained from a survey on 213 workers exposed to radiant energy were chronic hyperemic pigmented blepharoconjunctivitis (36.3%) which was supposed as a chronic abiotic and thermal lesion of photophthalmia, and pigmentation (melanosis) of bulbar conjunctiva near the limbus (11.5%)
2. Pterygium also was observed with high percentage (26.9%) and external irritative exposures in cluding ultra-violet rays were supposed to play a causative role in producing it.
3. Conjunctival and corneal foreign bodies (87.4%) were the most frequently observed among workers, due probably to improper protective eye equipment.
4. Every one case of leucoma cornea traumatica, leucoma adherens traumatica, burned scar of the lid skin, healed scar of macular burn, macular hole after contusion and post-enucleated anophthalmos after rupture of eye hall was observed.
5. None of cataract case in early stage could be found because the slit-lamp biomicroscope was not available in this screening examination.
6. By ophthalmoscopy, 19 cases of hypertensive retinopathies were observed.
7. Comparison this result with author´s former result obtained in 1966 also was made.
8. It is advisable to wear standard protective eye equipment and to administer health education to these workers.
