[Consequent use of the Aachen therapy concept after severe chemical burns of both eyes]

Severe chemical burn and its complications still are a serious threat to the afflicted eye, particularly in case of insufficient treatment. Rehabilitation of visual acuity can be achieved only in the minority of cases.

We present a 49-year-old female patient, who suffered a severe chemical burn in both eyes by alcaline detergent. Visual acuity was OD 20/50, OS light perception. After directly started acute treatment as well as peritomy, peridectomy, tenon plasty and application of a PMMA contact lens a stabilization was achieved. Complete rehabilitation of visual acuity was gained by EDTA abrasion, excimer treatment, penetrating keratoplasty and cataract surgery. Last examination showed a visual acuity of 25/20 in both eyes.

Even in severe chemical burn an optimal result can be achieved by using an adequate treatment conception. Immediate beginning of therapy is important as well as persistent and persevering application of the treatment. Repeated, if necessary daily, excisions of necrotic tissue associated with tenon plasty and application of a PMMA contact lens have special importance.
