Abstract Purpose:We report a case of branch retinal vein occlusion(BRVO)with intraocular inflammation(IOI)associated with retinal vasculitis(RV)after intravitreal ranibizumab(Lucentis®, Novartis Pharma AG, Basel, Switzerland)(IVR)administration.

Case:A 68-year-old Japanese female presented with 1 month of blurred vision in the left eye. She had a medical history of Sjögren's syndrome. The patient's best-corrected visual acuity was 1.5 in the right eye and 0.8 in the left eye, and intraocular pressure(IOP)was 16 in the right eye and 12 mmHg in the left eye. Fundus examination showed retinal hemorrhage in the inferior temporal area of the left eye. Optical coherence tomography(OCT)of the left eye revealed intraretinal fluid in the macula. We diagnosed macular edema associated with BRVO and performed an intravitreous ranibizumab(IVR)injection. One month after IVR administration, the best-corrected visual acuity improved and the macular edema resolved, though the patient complained of floaters. On slit-lamp examination, there were no inflammatory cells in the anterior chamber. Fundus examination showed vitreous opacity in the vitreous cavity and multiple whitish lesions throughout the fundus. Fluorescein angiography showed mild leakage from peripheral retinal vessels. Anterior chamber aqueous humor multiplex strip PCR test showed no infection. We diagnosed IOI associated with RV and performed a tenon triamcinolone acetonide injection. After one month of steroid treatment, the vitreous opacity and multiple whitish lesions disappeared.

Conclusion:Special attention should be given to the potential development of IOI associated with RV after IVR administration.
