Follow-up

Further Outpatient Care

Further care depends on the disease process that leads to peripheral anterior synechiae (PAS) formation.

Deterrence/Prevention

Appropriate and timely management of the disease process that can lead to PAS is necessary to prevent PAS from forming or progressing. This is the most important aspect of management because once PAS have formed treatment shifts to managing the sequela of PAS, intraocular pressure elevation, rather than the PAS itself.

Complications

Complications include elevated intraocular pressure leading to ocular pain, decreased visual acuity, and glaucomatous optic neuropathy with vision loss.

Prognosis

Peripheral anterior synechiae should be treated within 6 months of formation if the trabecular meshwork is to regain normal function [8] . Beyond this, the trabecular meshwork will have sustained permanent damage.

Ultimately, prognosis depends on the adequacy of management of the etiologic process that led to PAS formation.

Eyes with 360 degrees of PAS are unlikely to be treated adequately with medications and are likely to require a glaucoma filtering procedure.

Patient Education

Patient education depends on the disease process that led to PAS formation. Emphasis must be placed on the necessity of prompt treatment to prevent the progression of the condition.
