* Iris--is there sectoral iris atrophy (viral uveitis), mid-peripheral transillumination defect (PDS), iridodenesis or iridodialysis (previous trauma and angle recession), or polycoria/naevi (ICE)?
* Lens--is there pigment on the posterior lens surface, ruptured capsule, or leaking lens protein or phacodenesis (angle recession and previous trauma)?
The most common anterior segment injuries include hyphema, lens dislocation, cataract, angle recession
(3, 4) Angle recession is strongly associated with traumatic hyphaema with studies reporting a 60-100% incidence.
The aim of this study was to evaluate prospectively the incidence of angle recession and risk factors for development of traumatic glaucoma in closed globe injury.
Extent of angle recession, were noted and graded as <90[degrees], 90[degrees]-180[degrees], 180[degrees]-270[degrees], >270[degrees] Angle pigmentation were noted and graded as 0 (no pigmentation), 1 (Faint), 2 (Average), 3 (Heavy), or 4 (Very heavy).
Blunt ocular trauma of the eye can cause many complications including traumatic hyphema, iris damage, angle recession
, lens dislocation, lens opacity, anterior and posterior capsule rupture.
glaucoma is classified as a type of traumatic, secondary openangle glaucoma--a condition that may be underdiagnosed due to an often delayed onset and distant, perhaps forgotten history of eye injury.
It can lead to hyphema, iridocyclitis, iris sphincter tears, iridodialysis, cyclodialysis, lens subluxation, angle recession, retinal tear or dialysis, retinal detachment, vitreous hemorrhage or choroidal rupture.
Although the elevated IOP after blunt ocular trauma is transient in most cases, it is important to follow these patients for long as the patients with angle recession may develop angle recession glaucoma later in life.
In a survey on traumatic glaucoma conducted by Schlote T et al (18) angle recession, hyphema-associated and lens-associated mechanisms were the most common causes of traumatic glaucoma after blunt ocular trauma.
It can also be used to assess the effects of injury to the eyes, looking for signs of angle recession
, and congenital anomalies.
