A healthy 6-year-old boy with a clinical picture of central retinal artery occlusion (CRAO) of his left eye is presented here. The underlying cause was a trauma to the boy's left cheek some 6 months earlier. Possible pathophysiological mechanisms are discussed. To the best of our knowledge, the late onset of traumatic CRAO has not yet been reported in the literature.

We present a case of intraocular pentastomiasis in a 12-year-old Israel Arab boy. A single secondary pentastomid larva, most likely of Linguatula serrata, was found in the anterior chamber of the right eye, attached loosely to the pupil's border by a fibrinous mass. Associated conditions were iritis, subluxation of the lens, and secondary glaucoma. This is the first documentation of human pentastomiasis in Israel.
True cyclopia is a rare anomaly in which the organogenetic development of the two separate eyes is suppressed. A case of true cyclopia with normal karyotype is presented. There was a history of the use of an intrauterine device for contraception and of drug ingestion during early pregnancy. An anatomicopathological study of the monster with detailed presentation of the cyclopean eye is reported. The possible causes of cyclopia with particular relation to this case are discussed.
In 1976 we presented seven patients with anterior uveitis due to leptospirosis with positive serological tests. During the years 1975 to 1977 we had the opportunity to observe a further 16 cases. In most of these cases the serological tests were positive for more than one leptospira serotype--in one case even five. In all the follow-up cases during a period of two to seven months, there was complete recovery. We suggest that leptospirosis is a possibility which should not be overlooked in the diagnosis of anterior uveitis, especially bilateral, in young males working in field irrigation and dairy workers in known endemic areas.
Seven patients with anterior uveitis due to leptospirosis are presented. The diagnosis was based upon serologic tests and exclusion of other etiologic possibilities. Six patients came from a well-known endemic area of leptospirosis during the time of epidemics and one case came from an area which was not known to be endemic at the time. In 5 patients the uveitis was bilateral. The disease was mild in all but 2 patents who needed systemic administration of steroids. The posterior part of the eye was not involved in any of the cases.
