Objective To observe the clinical outcome of minimally invasive vitrectomy for ocular toxocariasis (OT). Methods The clinical data of 37 eyes in 37 patients with OT who underwent 23-gauge vitrectomy were retrospectively reviewed. There were 27 male patients and 10 female patients. The age was from 9 months to 22 years, with the mean age of (7.90±4.47) years. Patients who can cooperate underwent non-contact tonometer examination, slit lamp examination, fundus photography, ultrasound examination, optical coherence tomography and ultrasound biomicroscopic examination. The visual acuity was from no light perception to 0.6. According to the clinical type of OT, 18 eyes had posterior granuloma, 13 eyes had peripheral granuloma, 4 eyes had endophthalmitis and 2 eyes had atypical presentation. Seventeen eyes had vitrectomy for tractional retinal detachment (TRD), 13 eyes for epiretinal membrane (ERM), 6 eyes for TRD combined with ERM and 1 eye for endophthalmitis. Twenty-five eyes had lens-sparing vitrectomy, 12 eyes had lensectomy with vitrectomy; five eyes had limbus incision and 32 eyes had pars plana incision. Five eyes (13.51%) had reoperation. Followed up from 6 months to 39 months, with the mean of (13.90±10.25) months. Results Vision improved in 25 of 35 eyes (71.43%), was unchanged in 9 eyes (25.71%), and was declined in 1 eye (2.86%). Retina was reattached in 22 of 23 eyes that had TRD before surgery (95.65%); the rest one eye had redetachment (4.35%). Three eyes had cataract after surgery, which accounted for 12% in lens-sparing eyes. Among them, 2 eyes had lensectomy therefore. ERM was removed and had no recurrence in 18 of 19 eyes (94.74%). Conclusion Minimally invasive vitrectomy for OT patients can improve their vision and achieve retinal reattachment.
