Outcome Measures

Primary Outcomes (1)

  • Resolution of pseudo membrane associated with ligneous conjunctivitis

    Patient to be observed daily to every few weeks for resolution, based on clinical observation

    From date of first documented recurrence of pseudo membranes up to two years, starting from the date of enrolment

Study Arms (1)

Allogenic Plasma Aliquots

EXPERIMENTAL

Allogenic Plasma Aliquots to be used as eye drops in the treatment of recurrences of ligneous conjunctivitis. Two drops will be administered to the affected eye, every 1 to 4 hours, depending on severity of the recurrence.

Biological: Allogenic plasma aliquots, a source of plasminogen

Interventions

Plasma eye drops, a source of plasminogen
