[Case of retinal ischemia and retinal arteritis secondary to intravitreal nuclear drop].
BACKGROUND
A rare case of retinal arteritis and retinal ischemia as an incomplete branch retinal artery occlusion is reported following dropped lens fragments into the vitreous body.


METHODS
A 69 year-old-woman had a cataract OD with corrected visual acuity of 0.4. When she underwent phacoemulsification on March 11, the posterior capsule was damaged and nucleus fragments dropped into a vitreous body. A few days later, the vitreous opacity increased. The corrected visual acuity OD dropped to 0.06 due to anterior chamber inflammation and the intraocular pressure increased to 26 mmHg. During a pars plana vitrectomy on May 7, some retinal whitening were observed and incomplete branch retinal artery occlusion was confirmed by fluorescence fundus angiography. The corrected visual acuity finally improved to 0.3, but the right visual field defect remained.


CONCLUSIONS
Incomplete branch retinal artery occlusion caused by phacoanaphylactic endophthalmitis secondary to lens fragments in the vitreous cavity seems to be a rare condition related to retinal whitening. The timing of pars plana vitrectomy should be considered before retinal arterial sheathing or retinal whitening can be noted.
