Perilimbal ischemia

The perilimbal ischemia is the breaking of the conjunctival and episcleral vessels resulting in a plus or minus spread white avascular areas around the edge of the limbus (Fig. 7.3). 

The eyes are the organs most sensitive to SM injury. Acute effects are conjunctivitis, with dry eye, pain and photophobia. More than 60% of eye injuries recover and vision is restored. The remaining patients develop chronic or delayed-onset mustard gas keratopathy (MGK). Khateri et al (2003) reported that 35% of injured veterans had mild ocular injury (dry eye, conjunctival scarring and decreased visual acuity) and 3.6% had moderate injury that included some corneal involvement. Severe symptoms were described in fewer than 1% of patients. MGK is characterized by chronic blepharitis, meibomian gland dysfunction, dry eye, perilimbal conjunctival ischemia.
