Abstract
PURPOSE
To analyse risk factors for the development of superior limbic keratoconjunctivitis (SLK) in thyroid eye disease (TED).
METHODS
This prospective, observational study included 638 eyes/sides from 319 patients with TED. The eyes were classified into two groups, based on the presence and absence of SLK. Multivariate logistic regression analysis was performed to evaluate potential risk factors, including sex, patient age, past treatment history (steroid, orbital radiotherapy and radioiodine therapy), smoking, clinical activity score, margin reflex distance (MRD)-1 and -2, Graefe sign/lid lag, Hertel exophthalmometric results, Schirmer's test results, tear break-up time (TBUT) and tear meniscus height (TMH).
RESULTS
SLK was found in 198 eyes (31.0%) from 121 patients. Young age (OR, 0.977; P = 0.006), smoker (OR, 1.785; P = 0.009), presence of Graefe sign (OR, 2.912; P < 0.001), absence of lid lag (OR, 0.485; P = 0.031), high Hertel exophthalmometric values (OR, 1.125; P = 0.002), shorter Schirmer's test results (OR, 0.962; P < 0.001), shorter TBUT (OR, 0.815; P = 0.002) and high upper TMH (OR, 1.003; P = 0.013) were associated with the development of SLK. A high MRD-1 measurement value also tended to be associated with a risk of SLK, with an OR of 1.187 (P = 0.056).
CONCLUSION
The present study proposed several risk factors in relation to the development of SLK in TED.
