A Potpourri of Ocular Disorders

Two manuscripts focus on anterior segment disorders in children. The first paper raises concerns regarding the high rate of vitamin A deficiency-related night blindness in Sudanese school children. Although the incidence of vitamin A deficiency has been declining worldwide, it remains a public health concern in the developing world. A recent study from India also suggested that schoolchildren are vulnerable to this disorder. A second paper reports on the presence of thick corneas in Iranian children with congenital glaucoma. Although the central corneal thickness in this cohort was significantly thicker than age-matched controls, the average pachymetry below the 600 μ mark in both treated and control groups. This outcome is in contrast to studies of children undergoing cataract surgery where corneal thickness was normal preoperatively and increased postoperatively following cataract surgery.
