Corneal involvement in acrodermatitis enteropathica: a case report.

A case of acrodermatitis enteropathica occurred with corneal changes consisting of superficial punctate lesions, nebulous subepithelial opacities and linear epithelial erosions. These manifestations exacerbated intermittently whenever the patient ran out of her oral zinc sulphate therapy, but regressed and disappeared when she resumed her medication.

Causes of blindness and restoration of sight for the students in the School for the Blind, Khon Kaen.

One hundred and twenty-seven students from the School for the Blind, Khon Kaen, were seen between August 1984 and December 1987. There were 92 males (72.4%) and 35 females (27.6%). The age ranged from 3 to 19 years with the predominant age group being 6-15 years. The majority of the students (95.3%) resided in the Northeast. Only 26 students (20.5%) had positive family histories. Blindness caused by lesions affecting the whole eye was the leading cause of blindness (36.2%). About half of the cases of blindness were preventable and treatable. Most of them (58.3%) were second grade blind. Of all the students seen, 26 students (20.5%) were subjected to treatment for restoration of sight. Only 19 students had complete follow-up post-operative vision. The average visual improvement after treatment was forty-two per cent. The category of blindness was changed to the better side. Blindness was decreased. Visual impairment increased 36.8 per cent after treatment.

Early laser photocoagulation for idiopathic central serous choroidopathy.

Prolonged or recurrent serous detachment at the macula may cause permanent visual impairment in patients with idiopathic central serous choroidopathy. Early treatment and early resolution of the disease are therefore hypothesized to prevent this visual deficit. In this study, early laser photocoagulation of the leakage site in 25 patients with idiopathic central serous choroidopathy was performed, as compared to 25 control patients. The results of the study were promising. Rapid absorption of subretinal fluid was noted in the laser-treated group (2.37 +/- 1.63 weeks), compared to the untreated control group (7.55 +/- 4.17 weeks). Early visual recovery was also noted in the laser-treated group. Moreover, there was no recurrence in the treated group after a one-year follow-up period. Contrast this with the control group who showed cumulative recurrent probability of 70.84 per cent by using Kaplan Meier survival analysis.
