Chronic treatment with steroids can lead to steroid-induced glaucoma.Although the diagnosis of angle-recession glaucoma is evident after careful gonioscopy and optic nerve examination, other differential diagnoses for unilateral glaucoma should be considered. Uploaded on Oct 1, 2012. Argon laser trabeculoplasty in secondary form of open angle glaucoma. Trabeculectomy with mitomycin C in the treatment of post-traumatic angle recession glaucoma.

Such findings might include iris sphincter tears, corneal scars, Vossius ring, iridodialysis, iridodenesis, phacodenesis and hyphema. Spaeth GL. Angle recession of more than 180 degrees is deemed a considerable risk for secondary glaucoma, although glaucoma can develop when the area of recession is smaller than this.In one study, researchers found that approximately 50 percent of patients with traumatic glaucoma developed open-angle glaucoma in the unaffected, contralateral eye, suggesting that these patients may have an underlying genetic predisposition to developing glaucoma, which may be accelerated by a traumatic insult.In some cases, IOP may be low secondary to decreased production of aqueous humor from associated inflammation, a transient increase in aqueous outflow facility from disruption of structures in the angle, or the presence of a cyclodialysis cleft.Gonioscopy may aid in the diagnosis of other angle abnormalities from trauma, such as iridodialysis or cyclodialysis. University of Iowa Carver College of Medicine. Sihota R, Sood NN, Agarwal HC. Some normal eyes have a broad ciliary body band thus it is important to compare suspected areas of recession to the opposite eye to see what the “normal” ciliary body band looks like to avoid mistaking physiologic or even 360-degree recession as normal. Treatment for ARG is generally the same as for primary open angle glaucoma save for a few exceptions noted below. Sometimes, an eye injury can damage this drainage system, a condition called angle recession. Gonioscopy is central to the glaucoma exam, and may be the most important factor in making a correct diagnosis.1 The most common cause of incorrect glaucoma diagnosis is omission of gonioscopy, particularly when slit lamp examination shows no sign of angle closure or i… Recession of the anterior chamber angle is a common slit lamp and gonioscopic finding following concussive ocular trauma.

Secondary glaucoma after trauma is more likely to occur with a closed-globe injury, but it is often underdiagnosed because its onset may be delayed and the history of eye injury may be remote or overlooked.Angle recession is a common manifestation of blunt ocular trauma and involves rupture of the ciliary body face, resulting in a tear between the longitudinal and circular fibers of the ciliary muscle. He has mildly elevated IOPs and extensive angle recession in both eyes. Jensen OA. Tonjum AM. These resultant shock waves traversing the interior of the globe are responsible for other anterior segment damage accompanying angle recession, such as pupillary sphincter tears, iridodialysis, cyclodialysis and zonular tears.The shearing forces to the drainage angle result in a tear between the longitudinal and circular fibers of the ciliary muscle.

Approximately 5 to 20 percent of eyes with angle recession develop angle-recession glaucoma.This brief review will discuss the pathophysiology and clinical course and signs of angle-recession glaucoma, along with differential diagnosis and treatment strategies.Blunt force to the globe causes an anterior to posterior axial compression with equatorial distension. However prostaglandin analogues have a theoretical benefit of bypassing the dysfunctional trabecular meshwork by increasing uveoscleral outflow and can be used after the acute phase is over. A small percentage of these people go on to develop glaucomatous optic neuropathy and vision loss days, months or even years later Angle recession was first described by Collins in 1892It has been reported that up 60% of eyes with non-penetrating or concussive trauma will develop some degree of angle recessionThe main risk factor for angle recession is trauma. On the pathological examination of three eyes lost from concussion. Traumatic glaucoma. Blunt force to the globe causes an anterior to posterior axial compression with equatorial distension.
