To describe the acute and late ocular manifestations of toxic epidermal necrosis (TEN), Stevens-Johnson syndrome (SJS), and overlap syndrome and to identify predictors for the development of ocular complications.

A long-term retrospective study was conducted on two groups of patients affected with typical central serous chorioretinopathy (CSCR). One group was not treated and the other was treated by direct argon laser photocoagulation. CSCR shows a long-term good prognosis of visual acuity. The visual acuity of laser-treated eyes improves significantly (P less than or equal to 0.05), particularly in single focus cases (P less than or equal to 0.01). Unfortunately, these results cannot be statistically compared to the natural course of the non-treated patients because of the initial inhomogeneity of the two groups. Laser treatment did not produce any long-term complications. The recurrence rate in treated and untreated eyes was similar.

Proliferative sickle cell retinopathy (PSCR) is the most frequent vision-threatening complication of sickle cell disease (SCD). We investigated the relationship between the severity of sickle cell retinopathy in heterozygous (SC) or homozygous (SS) adult SCD patients and the clinical and laboratory data obtained during visits to a national SCD referral center. This retrospective longitudinal analysis included 942 SCD patients (313 patients with SC and 629 with SS disease) with ophthalmologic evaluations who were followed over a 19-year period by a multidisciplinary team in a referral center. PSCR was graded using the Goldberg classification. We identified patient and SCD characteristics associated with sickle cell retinopathy severity using multinomial logistic-regression models. Multivariate analysis associated severe PSCR forms (stages III-V) with older age (p=0.032), pulmonary involvement (documented pulmonary hypertension with pulmonary arterial pressure≥40 mm Hg, restrictive syndrome>20%, or previous history of pulmonary embolism diagnosed by vascular imaging) (p=0.029), deafness or tinnitus (p=0.026), and no history of osteomyelitis (p=0.013) for SC patients; and with older age (p<0.001), male sex (p=0.003), and acute pyelonephritis (p=0.04) for SS patients. The model of severe PSCR versus no PSCR showed good calibration and discrimination for SC and SS patients. Awareness of the clinical and laboratory factors significantly associated with severe PSCR in patients with SC or SS SCD may contribute to improved preventive strategies.
