Objective: To investigate the clinical features and side effects, with regard to glucocorticoid-induced ocular hypertension, glaucoma or cataract in children with primary nephrotic syndrome. Methods: Clinical data were collected and analyzed from 71 cases of primary nephrotic syndrome with glucocorticoid-induced ocular hypertension, glaucoma or cataract from Jun. 2014 to Jun. 2016. These children were hospitalized in Peking University First Hospital. Results: Totally 1 580 children with primary nephrotic syndrome were collected, glucocorticoid-induced complications in eyes were found in 71 cases, and the incidence was 4.5%. There were 66 cases with ocular hypertension, 2 cases with glucocorticoid glaucoma, 2 cases with glucocorticoid glaucoma combined with cataract, 1 case with high intraocular pressure combined with cataract. There were 41 boys and 30 girls with eye-related side effects caused by glucocorticoid. The average age of onset of glucocorticoid-induced eye adverse reactions in children with primary nephrotic syndrome in our research were 8 (2, 16) years. The average duration or interval time from glucocorticoid medication use to eye adverse effects was 157 (6, 420) days. No statistical significance was found in intraocular pressure between different genders, types of glucocorticoid, different route of glucocorticoid and whether methylprednisolone pulse treatment (P>0.05). There was no significant correlation between age, body mass index, blood pressure, cumulative dosage, duration time of glucocorticoid, mean daily dosage and glucocorticoid-induced ocular hypertension (P>0.05). The ocular hypertension was controlled after treatment. Conclusion: Children with nephrotic syndrome after treatment of glucocorticoid are susceptible to ocular complications, and the occurrence of ocular hypertension is closely related to glucocorticoid susceptibility of the nephrotic children. Regular eye monitor is indispensable for the children suffering from primary nephrotic syndrome.
