Fourty eyes with primary congenital glaucoma were
selected to be inclUded in the stUdy. Eighteen eyes with
corneas clear enough to allow proper gonioscopy were
operated on by goniotomy. Twenty two eyes with hazy to
opaque corneas were operated on by trabeculotomy ab
externo.
The technique of each operation and the results of
each, were compared with those of other investigators.

Goniotomy is the prefered operation for every case
with clear cornea as it is less traumatic to the eye,can be
repeated several times when necessary, and do not
compromise the conjunctiva for subsequent surgery if
needed. Its drawback is that it needs special surgeon
familiar with the normal and pathologic appearance of the
angle in infants and children. It needs a trained
assistant and a deep anterior chamber that permits good
visiblity of angle structures.
Trabeculotomy ab externo has the advantages of higher
Success rate (90.9% Compaired to 83.3% with goniotomyl, can
be done with undiminished accuracy in eyes with opaque
corneas. It does not need a well trained assistant.
Far its success it need good localization and exposure
of the canal of Schlemm whi c h should be patent to be
cannulated and ruptured internally.
Both operations seemed to be safe with minor
complications; the most common of which was hyphema that
occurred in 60% of cases but it was mild in most eyes and
need one to two days to be absorbed. Other complications
were iridotomy in three eyes, and iridodialysis in two
eyes, failure to find Schlemm’s canal in one eye,
detachment of peripheral part of Descemet’s membrane in two
eyes and filtering bleb in two eyes.
The importance of life-long follow up was stressed.
