Comparison of the acute ocular manifestations of Stevens-Johnson syndrome and toxic epidermal necrolysis in Chinese eyes: a 15-year retrospective study

Table 3 This table shows the severity of ocular involvement during the acute phase in the two groups, using the grading system based on that described by Sotozono et al. [17] The TEN group had significantly more mild involvement than the SJS or SJS/TEN overlap group (p = 0.018), while in all other groups, no statistically significant differences were found (p > 0.05)

Grading	Stevens-Johnson syndrome and SJS/TEN overlap	Toxic epidermal necrolysis
0 (None)	12 (60%)	3 (25%)
1 (Mild)^a	1 (5%)	5 (42%)
2 (Moderate)^b	4 (20%)	2 (17%)
3 (Severe)^c	3 (15%)	2 (17%)

^aGrade 1 (mild involvement): eyes with conjunctival hyperaemia
^bGrade 2 (moderate involvement): eyes with pseudomembrane formation or presence of epithelial defects
^cGrade 3 (severe involvement): eyes with both pseudomembrane formation and epithelial defects
