Long-term follow-up of excimer laser phototherapeutic keratectomy.

PURPOSE: To evaluate long-term follow-up results of excimer laser phototherapeutic keratectomy (PTK) in a Japanese population. METHODS: Twenty-six patients (31 eyes) with corneal opacity were treated with excimer laser PTK. Preoperative diagnoses included 16 eyes with band keratopathy, 10 with granular dystrophy, and 5 with corneal scar. Mean postoperative follow-up was 27 months. RESULTS: Corneal opacity was reduced in all patients. At postoperative month 12, best spectacle-corrected visual acuity (BSCVA) improved from the preoperative level in 22 eyes of 28 eyes, did not change in 3 eyes, and declined in 3 eyes. BSCVA at month 24 was better than the preoperative acuity in 17 eyes of 23 eyes, similar in 1 eye, and worse in 5 eyes. Eyes with granular dystrophy showed significantly better BSCVA improvement than those with band keratopathy. A hyperopic shift of +1.0 diopter or more occurred in 14 eyes of 28 eyes at month 12 and in 12 eyes of 23 eyes at month 24. No serious adverse effects were encountered during the 3-year follow-up period. CONCLUSIONS: Excimer laser PTK is a safe and effective procedure for the treatment of Japanese patients with superficial corneal opacity.

Evaluation of the nutritional condition and absorptive capacity of nine infants with short bowel syndrome.

Nutritional conditions and absorptive capacity of nine infants with short bowel syndrome were investigated during a long follow-up period from 1.5 years to 14 years and 7 months. The length of the residual small intestine ranged between 13-90 cm. The nine infants had normal meals at home and most of them did not suffer from persistent diarrhea. Most of the infants were thin. Nutritional parameters were kept relatively normal. The results of D-xylose absorption test had gradually improved, but the absorptive capacity of sugars and amino acids, observed by potential differences, were within the normal limits or slightly subnormal except for one infant. This indicated that the absorptive capacity of sugars and amino acids per a given area of the residual small intestine did not increase. Severe steatorrhea continued for several years in infants with less than 50 cm of small intestine. In these infants the concentration of serum vitamin D and total cholesterol were below the normal limits and the absorption of bile acids was disrupted. From our examination, infants with less than 50 cm of small intestine must be followed up for a long period and nutritional supplements are necessary.
