![]() ![]() However, the high iris insertion appears to be more pronounced in eyes with glaucoma. )The extent of iris defects and iris stands in the angle do not correlate well with the severity of glaucoma. Development arrest of the neural crest cells with their retention in the anterior chamber angle during gestation results in incomplete development of the trabecular meshwork or Schlemm canal. ((Glaucoma is seen in approximately 50% of the cases with ARS. Posterior Embriotoxon displacement of SL anteriorly ( prominent Schwalbe line)īL not associated to corneal endothelial changes or edema. Īngle recession should be differentiated from cyclodialysis, which is the disinsertion of the ciliary body from its attachment to the scleral spur.Ī number of anterior segment abnormalities often accompany angle recession, as follows: Ipsilateral anterior chamber depth may be increased following a contusion injury even if other signs of angle recession are absent. ![]() Documented asymmetry supports the diagnosis. Ĭomparison with the angles in the injured and uninjured eyes is important, particularly in cases with subtle findings. In fact, when many years have passed after the contusional injury, angle recession may be difficult to recognize.Ī large series of blunt injuries among soccer players found that angle recession is more likely to occur in the superotemporal quadrant. After years of healing, the fissure may no longer be visible. This characteristic appearance is due to a cleavage between the longitudinal and circular muscles of the ciliary body. The angle appears abnormally deep in the involved areas. Typically, an irregularly wide ciliary body band is visible with retroplacement of the iris root. The clinical appearance of the affected angle varies with the depth of the tear in the ciliary body and with the amount of time passed after the injury. High IOPs noted early after injury (within the first few months of injury) may indicate extensive trabecular damage and a poor prognosis.Īngle recession is typically diagnosed by means of gonioscopy. ![]() Ideally, angle recession should be discovered before glaucoma develops so that the risk of glaucoma can be assessed and follow-up care arranged accordingly. may not be noted in early stages of the disorder. Eyes with angle recession of greater than 240° appear to be at the highest risk of chronic glaucoma. PAS at the border of the recession Glaucoma after angle recession of less than 180° is unusual recessions greater than 180° are associated with a 4-9% incidence of glaucoma. ![]()
