Abstract
Postoperative endophthalmitis is a rare but potentially vision-threatening complication following intraocular surgery. We report two cases (one acute onset and one delayed onset) of postoperative endophthalmitis treated with vitrectomy, in which ocular circulation was quantitatively monitored using laser speckle flowgraphy (LSFG). Both cases presented with vitreous opacity, hypopyon, and markedly reduced visual acuity. LSFG measurements demonstrated progressive improvement in both choroidal and retinal blood flow parameters after treatment, accompanied by a reduction in choroidal thickness. These circulatory changes correlated with visual recovery following treatment. Our findings suggest that LSFG may serve as a useful tool for monitoring therapeutic response and predicting visual outcomes in postoperative endophthalmitis.
