Owing to pseudoexfoliation glaucoma’s prevalence and severity, gonioscopy should be performed to assess for pigment deposition and a Sampaolesi’s line. Sampaolesi line is a sign which may be observed during a clinical eye examination. During gonioscopy if an abundance of brown pigment is seen at or anterior. The Glaucomas.

Various imaging studies can also be used to detect and monitor glaucomatous changes in the retinal nerve fiber layer and optic disc. Midperipheral iris transillumination defects occur in pigment dispersion syndrome. The Requisites in Ophthalmology.

Rarely, there is an acute rise in IOP which may cause symptoms of ocular pain, blurring of vision and seeing haloes. What Is Pseudoexfoliation Syndrome? Hypoxia can cause atrophy of the iris pigment epitheliumstroma, and muscles. This is thought to be a result of oxidative stress.

Decreasing pupillary movement may reduce iridolenticular friction and thus avert the liberation of iris pigment, slow the progression of trabecular blockage, and perhaps allow the meshwork to clear. Pseudoexfoliation glaucoma commonly presents unilaterally with IOP that tends to escalate faster than among patients with primary open-angle glaucoma POAG.

Pseudoexfoliation Glaucoma:

RegeneRx Biopharmaceuticals announced the outcome of discussions between its U. Hyperpigmentation of the trabecular meshwork occurs in patients with pigment dispersion syndrome. Szmpaolesi Ocuserts were ideal for patients with pigment dispersion syndrome or pigmentary glaucoma, because these drugs were well tolerated and effective at both lowering IOP and inhibiting pigmentary release.

Ocular echometry in the diagnosis of congenital glaucoma.

Flourescein angiography and ultrastructural studies have shown hypoxia of the the iris, and hypoperfusion may be a factor in development of exfoliation syndrome. Patients receiving laser trabeculoplasty should also be reexamined in three to six weeks. In cases of PXF with secondary angle closure due to zonular laxity, the key to distinguishing it from PACG is the asymmetry in anterior chamber depth, as well as the presence of pseudoexfoliative material.

One way of distinguishing this from primary angle closure is the relatively deep anterior chamber on the other likely less affected side. Drug Therapy In patients with exfoliation syndrome, inhibiting the release of pigment should slow glaucomatous progression by blocking the mechanism most responsible for elevated IOP in these eyes.

Of note, once laser trabeculoplasty starts to wear off, patients with pseudoexfoliation glaucoma tend to demonstrate a more rapid IOP increase than POAG patients.

Iridozonular contact during accommodation as well as during normal pupillary constriction and dilation disrupts the iris pigment epithelium and results in the deposition of pigmentary granules throughout the anterior segment.

Glaucoma Today is mailed bimonthly six times a year to 11, glaucoma specialists, general ophthalmologists, and clinical optometrists who treat patients with glaucoma. Pigmentary glaucoma is caused by pigment dispersion syndrome, an glaucomz dominant disorder characterized by pigment liberation from the iris epithelium.

The visual potential OS was low with only a remnant of vision in the temporal field, and the patient wanted topical medications before considering cyclodestruction of the ciliary body. Decreased pupillary dilation, along with weakened zonular fibers and synechiae between the iris and peripheral anterior lens capsule, make the cataract surgery technically difficult.
