PURPOSE: To examine the differences in surgical results between non-accommodative esotropia (NAE) and partially accommodative esotropia (PAE). METHODS: This retrospective study included 47 patients undergoing surgery for pediatric esotropia, defined as esotropia with a decrease in the deviated angle of greater than ten prism diopters (PD) upon administration of hyperopic spectacles. On the other hand, NAE was defined as esotropia with a decrease in the deviated angle of less than 10PD. We compared age at surgery, deviated angle at surgery, frequency of amblyopia, and deviated angle at each postoperative period in two groups. RESULTS: Twenty-nine patients belonged to the PAE group, and 18 patients belonged to the NAE group. The age at surgery in the PAE group was higher than that of the NAE group, and the deviated angle for surgical correction was smaller in the PAE group than in the NAE group. No statistically significant difference in the frequency of amblyopia presentation was found between the two groups. The surgical success rates were much higher in the PAE group at postoperative two years and at the final visit compared to those of the NAE group. CONCLUSIONS: In esotropic children who underwent surgery, the long-term surgical success rate was highest in the cases in which the esotropic angle was decreased by hyperopic correction.

BACKGROUND: There has been no reported case of arsine poisoning in Korea so far. This article presents the first reported case of arsine poisoning with hemolytic anemia accompanied by acute renal failure. Initially we suspected an infectious agent to be the cause of this case but later discovered that it was arsine poisoning suffered while working at a zinc-smelting industry in the process of recovering the cadmium by-product. We report this case and discuss the arsine poisoning. CASE REPORT: A 27-year-old man employed at a zinc-smelting industry was exposed to arsine while working in the process to recover the cadmium by-product.On the 4th day at work, he had to redissolve defected by-product into a pot and began to experience febrile sensation, diarrhea, upper quadrant abdominal pain, jaundice, and anorexia.After he was admitted to a hospital, the laboratory results showed hemolytic anemia, acute renal failure and elevated concentration of arsenic. He was thus diagnosed as suffering from arsine-poisoning and underwent hem dialysisand supportive therapy.He recovered from the poisoning after51 days and was discharged from the hospital. DISCUSSION: When workers dealing with arsenic-containing material present with hematuria, nausea, vomiting, abdominal pain, and dyspnea followed by hemolysis with acute renal failure, arsine poisoning must be suspected and diagnosis followed by treatment must commence immediately. If any future cases occur, blood and urine samples should be kept in storage so any necessary analysis can be processed later.
