keratorefractive surgery, and pediatric corneal diseases. He has received both an honor award and a senior honor award from the
American Academy of Ophthalmology. He has received seven research grants. He has traveled to many regions of the United States,
Europe, and Asia as an invited guest lecturer. He has extensive experience in laser vision correction and corneal transplant surgery
and has lectured at and moderated many national eye meetings. He is on the editorial board of the Journal of Pediatric Ophthalmology
and Strabismus and is a reviewer for all the major journals in ophthalmology. Dr Zaidman is the founder and president of the Pediatric
Keratoplasty Association.Through this society, Dr Zaidman has organized and promoted pediatric keratoplasty, an area of extreme
difficulty and complexity.

G laucoma is a frequent occurrence in pediatric corneal disease, and its management
requires special considerations. This expert interview with Gerald W Zaidman will consider
the definition, incidence, diagnosis and treatment of pediatric glaucoma, with the exception
of congenital glaucoma, which is not a disease of the cornea.
Q: How do we define pediatric glaucoma?
The pediatric age group is defined as children under the age of 16. However, older children can usually
be examined without difficulty; therefore, for the sake of our discussion we will focus on children
under the age of 6 years old. In the ophthalmic literature, glaucoma specialists have presented
varying definitions of pediatric glaucoma. Dr Paul Sidotti, when he lectured us, said that “glaucoma
in children is a disease of elevated intraocular pressure with resulting damage to the optic nerve.”
In their lectures, Drs Jeff Liebmann and Robert Ritch have observed that children tolerate a higher
intraocular pressure than adults.
Other pediatric glaucoma specialists look for increasing axial length or increased corneal diameter.
This phenomenon is not seen in adults. But in young children there can be pressure-induced
expansion of the globe prior to damage of intraocular structures. Therefore, is glaucoma in children
a disease of increased intraocular pressure, changes in the optic nerve, a disease of increasing axial
length, or a disease of increasing corneal diameter? Recently, in a monograph published after the
World Congress on Childhood Glaucoma, 1 the consensus was that children must have at least two or
more of the following: chronically elevated intraocular pressure greater than 21 mmHg (and typically
in the higher 20s in order to create some of the other ocular changes seen in glaucoma); an increased
cup-to-disc ratio or progressive cupping; an increase in corneal diameter, and an increase in axial
length or a myopic shift on refraction. If a child demonstrates two of these findings, then they have
Q: Which pediatric corneal diseases are likely to have glaucoma?
One can categorize pediatric corneal diseases into three groups—congenital diseases, acquired
traumatic diseases and acquired non-traumatic diseases. Congenital diseases, such as Peters’
anomaly, sclerocornea, congenital hereditary endothelial dystrophy, or congenital glaucoma make
up 70% of all pediatric corneal diseases. Within the congenital disorders, 70% are due to anterior
segment dysgenesis, and the rest are split between glaucoma and congenital hereditary endothelial
