[A case report of injecting gentamicin intraocularly by mistake being misdiagnosed as central retinal artery occlusion].

PURPOSE: To report a case receiving gentamicin injection intraocularly by mistake when subconjunctival injection and was misdiagnosed as central retinal artery occlusion.

METHODS

After a complete examination, including ocular fundus examination, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), the correct diagnosis was confirmed. The patient received a surgery of vitrectomy.

RESULTS

FFA revealed severe retinal vascular nonperfusion of the posterior pole. The final diagnosis was medicine toxic retinopathy from gentamicin. The visual acuity of the patient was counting figure/1 meter postoperationally. High intraocular pressure, scleral staphyloma and optic atrophy were detected during the follow-up.

CONCLUSION

Injecting gentamicin intraocularly by accident usually resulted from carelessness. The massive doses of gentamicin might result in the severe retinal damage, which could be misdiagnosed as central retinal artery occlusion. Much attention should be paid to avoid its occurrence. The examination of FFA can help make correct diagnosis. Through the vitrectomy, though the damage could't be reversed thorougly, the surgery of vitrectomy could resume a little effective vision for the patient.
