Purpose: To study the ocular manifestations, its severity and sequelae in patients with Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN).
Methods: Prospective study of 44 consecutive patients (30 SJS and 14 TEN) presenting in the acute phase of the disease. Patients were evaluated by dermatologist as well as physician for systemic status, skin lesions and mucosal involvement. Detailed history taking, visual acuity, ophthalmic evaluation (lid margin, corneal, conjunctival changes, tear film and ocular surface). Ocular severity score (OSS) was assessed at baseline (acute) and at 6 months (chronic / OSS6), graded as mild, moderate and severe.
Results: Mean age was 28.15 ± 15.78 years. Sixty-five eyes of 33 patients were included for final analysis. Thirty-eight patients (86.4%) had ocular manifestations. Drugs were the most common causative factor (95.4%). At base line mild, moderate, and severe OSS was seen in 43.1%, 44.6%, and 12.3% eyes. At 6 months mild, moderate, and severe OSS was seen in 44.6%, 7.7%, and 6.2% of eyes. There was a significant correlation between age of the patient and OSS at 6 months (p = 0.02). Younger age had higher chronic OSS. Patients with TEN had higher acute (p = 0.001) and chronic (p = 0.001) OSS than SJS. Three mucosal surface involvement associated with higher acute and chronic OSS (p = 0.001). No long-term ocular complications observed in 27 / 65 (41.5%) eyes. Acute OSS correlated significantly with chronic OSS, at 1 and 6 months (p = 0.001).
Conclusions: Greater severity of the disease, more number of mucosal surfaces involved and shorter symptom lag correlated with more severe acute and chronic ocular manifestations. The severity of lid margin involvement and corneal involvement in acute stage were good predictors of severity of chronic ocular findings. Initial severity of ocular involvement correlated with severity of ocular sequelae.
