A Case of Intraocular Erosion and Intrusion by an Arruga Suture.
OBJECTIVE
To report a case of intraocular erosion and intrusion by an Arruga suture.


METHODS
This study involved a 62-year-old male who had undergone scleral buckling surgery 40 or more years ago at another hospital for rhegmatogenous retinal detachment, as well as trabeculectomy 20 years ago for primary open-angle glaucoma, in his left eye at the same hospital. However, he recently became aware of blurred vision in that eye. Upon examination, iritis was observed in the anterior portion of his left eye, as well as a great number of pigment cell keratoprecipitates on the posterior surface of the cornea. In the ocular fundus, extensive atrophy of the retinal pigment epithelium and partial hyperpigmentation was observed, accompanied by subretinal strands, yet the retina remained attached. Around the entire peripheral area of the retina we observed a ring-shaped protrusion, but we also saw a shiny, filamentous material in the vitreous cavity that penetrated the sclera and choroid, completely extending from the 4- to 8-o'clock position of the scleral buckle protrusion. To treat the iritis in the patient's left eye, we began to administrate low-concentration steroid eye drops, after which the inflammation disappeared.


CONCLUSIONS
In this study, we experienced a case of intraocular erosion and intrusion by an Arruga suture, and opted to treat the patient with steroid eye drops and conservative follow-up observations unless retinal redetachment and/or vitreous hemorrhage occurs.
