The present case concerns what is best to our knowledge the rare case report of postoperative cilia in subtenon's space following subtenon injection of anesthesia, although many cases have been reported on intraocular cilia in the cornea, anterior and posterior chamber, lens, vitreous, and retina following penetrating injury.

| Introduction|| |
Cilia can enter eye either as a result of penetrating surgery or following penetrating trauma.,,,, The presence of intraocular cilia following penetrating injury or surgical injury is rare. It was first reported by Lerche. Cilia can be entrapped in the cornea, anterior chamber, posterior chamber, lens, vitreous, and retina.
| Case Report|| |
A 55-year-old male patient visited our hospital with complaints of decreased vision in both eyes (BE) for 6 months of duration with no systemic illness. On examination, BE showed uncorrected visual acuity 6/60 and best-corrected visual acuity 6/12. BE showed nuclear sclerosis grade 2 and posterior subcapsular cataract. He underwent right eye small incision cataract surgery. On the 1st postoperative day, vision improved to 6/9 and advised tapering dose of steroids. Subsequent postoperative visit at 2 weeks, we noted few cilia in the subtenon's space at inferonasal quadrant without any ocular inflammation [Figure 1] and [Figure 2]. He did not have any previous history of ocular trauma. We reviewed the patient after discontinuation of postoperative medication in 1 month and the 3rd month; he did have any irritation and had no signs of ocular inflammation. As the patient was not willing for the second procedure for the removal, and as he did not have any inflammation due to cilia in subtenon's space, he was advised for regular follow-up and to report in case if any signs of inflammation developed.

| Discussion|| |
The response of the eye to the intraocular cilia is unpredictable and variable. In the early postsurgical or post injury period, infection and inflammation can cause severe corneal edema, graft rejection, nongranulomatous iritis, cyst, abscess formation, retinal detachment, and endophthalmitis.,,,, Many cases remain asymptomatic without any inflammation, and only very rare cases end with blinding complications. A literature review revealed that cilia entrapped in the anterior chamber remain innocuous and sometimes cause inflammation., A case report on posttraumatic cilia remaining inert in the anterior chamber for 50 years without any inflammation has been reported.
In our case, cilia were entrapped in subtenon's space, and the cause of cilia entrapment in subtenon' space may be due to following subtenon anesthesia as the site was inferonasal. Moreover, cilia may or may not cause inflammation, but in our case, there are no signs of inflammation, so left without any intervention.
| Conclusion|| |
Although many cases reported on intraocular cilia following trauma, to our knowledge, this case is a rare report of subtenon's space cilia following subtenon block. In spite of the organic nature, intraocular cilia can be tolerated for many years without any serious ocular inflammation. However, precautions have to be taken during preoperative and intraoperative periods to avoid entrapment of any intraocular foreign body to avoid further complications.
