The name ‘eyebright’ also touches another theme of the Euphrasia pathogenesis: the remedy has caused obscuration of vision in the provings. The provers could see things only as through a veil, sometimes so indistinctly as if the objects were in constant motion; the light sometimes seems to waver as if the mains supply were overloaded and the bulb suddenly burned darker than usual (‘brownout’). Euphrasia may act as a ‘brightening’ in such condi- tions of obscuration. Incidentally, it has not only been used successfully in subjective changes of vision but also, for instance, in dimness of the cornea (pannus) and even after cataract operations.
The mucopurulent discharges may be so profuse that the eyelids will agglutinate overnight. The lachrymation is acrid and profuse as well. Tears begin to flow immediately in cold air, and especially from exposure to wind.
In the ophthalmia of Euphrasis, there is another striking feature besides the profuse and acrid secretion: a severe hyperaemia which not only causes redness of the eyes but also much injection. The Materia Medica Pura already says: ‘Vessels running through the white of the eye nearly to the cornea’ and similar observations are related from many cured cases.
Finally a feature of Euphrasia which is unfortunately little known should be stressed: the alternation (or else combination) of eye symptoms and complaints in remote regions of the body. For example: eye symptoms alternating with abdominal pain; ophthalmia occurring when menstruation is disturbed or suppressed; ophthalmia after gouty pain in one foot has been removed; lachrymation with sneezing and prostatic trouble.
But the most frequent accompanying symptoms of eye complaints are symptoms of the respiratory tract, and especially coryza. Much sneezing, sometimes constant irritation to sneeze the whole day. There is profuse fluent coryza, not only forward
