    Of the sera obtained from 18 patients with ocular diseases comprising ocular larva migrans (OLM), Toxoplasma gondii, Mycobacterium chelonei, Pythium insidiosum, bacteria and tumour, 3 sera were positive for Toxocara antibody at the titre over 1/1600 ELISA. All 3 of these sera came from males with unilateral grayish fundi. We demonstrated the value of the direct immunofluorescent assay (DIFA) on vitreous specimens from 7 cases of Toxoplasma retinitis. One vitreous specimen under electron microscopic examination revealed bradyzoites of T. gondii. In addition, a few cases of keratoconjunctivitis corneal ulcer with endophthalmitis, due to P. insidiosum, Ps. pseudomallei and Mycobacterium chelonei, were also diagnosed.
