ABSTRACT
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.

The natural course, related complications and factors affecting prognosis of traumatic hyphema in 149 Thai patients were reported. Male preponderance and high prevalence of patients younger than 15 years were noted in this study. Blunt ocular trauma was the most common type of eye injury (88.59%), with penetrating injury (7.38%) and missile (4.03%) being the next in order of decreasing frequency. Duration of injury was acute in 81.88 per cent, subacute in 12.08 per cent and chronic in 6.04 per cent. Complications from secondary glaucoma accounted for 24.16 per cent, whereas, corneal blood staining and rebleeding were 10.07 and 6.71 per cent respectively. Shorter duration of injury, good initial visual acuity and absence of complications were responsible for favorable visual prognosis. However, age, grade of the initial hyphema and surgical intervention were not demonstrated to have any influence on the eventual visual outcome.
