A mature larva of a psychodid fly was recovered from the left eye of a 37 year old patient who was suffering from an irritative feeling of the eye. The larva was collected from water used to wash the eye of the patient, and was brought to the author for identification. The specimen was already at the mature stage and its digestive canal was clean. It was actively moving in water when first exmined by the author. It was transferred into a small glass vial on wet filter paper in order to recover the adult, but it died 2 days later without the pupation. The specimen was mounted in balsam medium for the detailed microscopical examination of the structure. The larva is 7mm long, body greyish white in general, and the head and siphon are dark brown. There are 3 plates on each of the abdominal terga VI and VII, 5 pairs of siphonal tufts and 4 valves on the siphon, which is slender and tapering. The specimen was identified as Psychoda alternata Say, 1824 from its morphological characters. This case is considered to be the first report on human ocular myiasis due to the psychodid larvae.
