The corneo-scleral changes described are highly characteristic and may be the first signs of an underlying systemic disorder so that otherwise healthy patients who present with limbal guttering and scleral disease must be continuously monitored with this association in mind. The clinical and histological features of limbal guttering in connective tissue disorders strongly suggest that a local antigen-antibody reaction triggers off a number of biochemical and cellular responses which combine to produce lysis of scleral and corneal collagen, although immune complexes have not so far been demonstrated in these eyes. Modes of therapy aimed at one particular chain of events have varying degrees of success, as indeed does more blunderbuss treatment with steroids, anti-inflammatory drugs, or cytotoxic agents. The early stages of the ocular lesion in the rabbit are now being studied, as is the immunological basis for its production. It is hoped that further work with the animal model will lead to a deeper understanding of the pathogenesis of these conditions, which will turn provide both ophthalmologists and rheumatologists with more scientific guidelines for treatment.
