Glaucoma, Juvenile: Differential Diagnoses & Workup
Updated: Feb 22, 2008
- Overview
- Differential Diagnoses & Workup
- Treatment & Medication
- Follow-up
Differential Diagnoses
Other Problems to Be Considered
Late-recognized primary congenital glaucoma, glaucoma secondary to uveitis, steroid glaucoma, and iridocorneal dysgenesis
Late-recognized infantile glaucoma (anterior segment signs of infantile glaucoma, such as breaks in the Descemet membranes and corneal enlargement)
Glaucoma associated with a systemic disease (see Background)
Glaucoma associated with a primary eye anomaly, such as Axenfeld anomaly (see Background) Glaucoma secondary to another eye disease, such as trauma, uveitis, or steroid use
Evidence of a narrow-angle glaucoma
Workup
Laboratory Studies
- Mutational analysis of the myocilin gene at chromosomal region 1q21-q31 can be performed. More than 50% of disease-causing alleles may be screened by restriction enzyme analysis.
Imaging Studies
- Glaucoma assessment - Field testing, fundus photography, and retinal tomography
Procedures
- See Physical.
Histologic Findings
An isolated report by Tawara and Inomata found an abnormal compact trabecular meshwork in patients with juvenile glaucoma.1
