We classified superficial punctate keratitis (SPK) regarding its severity using the area and density of the lesion as parameters. The affected area is determined by fluorescein staining: A0 when there is no punctate staining, A1 when the affected area occupies less than one-third of the corneal surface, A2 when the affected area occupies one-third to two-thirds of the cornea and A3 when the area is more than two-thirds of the cornea. The density is also determined by fluorescein staining :D0 when there is no punctate staining, Dl when the density is sparse, D2 when the density is of moderate degree and D3 when the lesions are high in density and overlap one another. A group of 54 ophthalmologists were then asked to grade 30 color slides of SPK according to the above classification. Over 50% of ophthalmologists gave matching gradings regarding either the area or density for 29 out of 30 slides 97%, Over 50% of ophthalmolo-gists gave matching gradings regarding both the area and density for 20 out of 30 slides, 67%. The current classification thus seemed to be of value in the clinical follow-up of SPK cases and in the evaluation of therapeutic efficacy.
