Conjunctival appearance in corneal xerophthalmia
A. Sommer
We studied the appearance of conjunctiva in 50 consecutive cases of vitamin
A-responsive conjunctival xerosis (X1) and 162 consecutive cases of
nutritional keratopathy (corneal xerosis [X2] and stromal loss [X3]).
conjunctival xerosis, most extensive at or shortly after the onset of frank
corneal involvement, was present in 101 (95%) of 106 eyes of cases of X2
but in only 99 (64%) of 155 ulcerated/necrotic eyes (X3A and X3B).
Forty-four percent of involved eyes were inflamed, the percentage
increasing with the severity of corneal disease. In 20 patients with
nutritional keratopathy, conjunctival xerosis was monocular: inflammation
was more prevalent and corneal involvement more severe in the nonxerotic
eyes. In patients with precipitous deterioration of vitamin A status,
clinically recognizable alterations of the cornea sometimes developed
before any changes appeared in the conjunctiva.
