This relatively small series supports the accumulating evidence that a combined cataract extraction and trabeculectomy procedure gives satisfactory results in both respects.

Ultrasonic fragmentation can be used to fragment various tissues such as the lens, the vitreous, the iris and ciliary body, so that they may be aspirated through a 23-gauge cannula. Since the technique was first described in 1973, it has been used in 148 eyes in a variety of conditions with encouraging results.
2 cases of congenital glaucoma combined with a general metabolic disease are described. 1 patient displayed the symptoms of a mucopolysaccharidosis (Hurler's syndrome), the other patient showed the characteristics of Lowe's oculo-cerebrorenal syndrome. In both patients a surgical trabeculectomy was performed. The excised tissues were analysed by electron microscopy. Distinct vacuolar or fibrillar deposits were observed in both cases in the trabecular region and in Schlemm's canal. Possibly, these alterations could have contributed to the raised intraocular pressure in both patients.
Aniseikonia as well as binocular vision and depth perception are measured in 114 patients with unilateral pseudophakos. 86% of the cases exhibit a small degree of aniseikonia (3% or less). However, binocular vision and stereopsis remain subnormal or approximatively normal.
