A 28-year-old man who had undergone vitrectomy with placement of a 360-degree encircling six years ago for retinal detachment in the left eye presented with complaints of redness in the left eye for two weeks. On slit-lamp examination, the encircling band was found to have anteriorly migrated nasally [Figure 1]a. Anterior segment optical coherence tomography (ASOCT) revealed a thin scleral flap underneath the displaced encircling band nasally [Figure 1]b. Extraocular movements were normal. Nishida et al.[1] reported transmuscular migration of an encircling band in a patient. Kim et al.[2] also described anterior migration of an encircling band anterior to the medial rectus muscle. However ASOCT findings on the migration of an encircling band have not been described in literature. Based on our findings, we hypothesize an intrascleral migration of the encircling band nasally without damaging the medial rectus muscle insertion. ASOCT helped us in judging the depth and route of migration of the encircling band. ASOCT is beneficial in assessing the scleral thickness beneath the migrated encircling band before planning surgical removal.
Figure 1: (a) Slit-lamp picture of the left eye shows displaced encircling band nasally (black arrows). (b) ASOCT of the nasal sclera shows a thin scleral flap below the displaced encircling band (blank blue arrows). The medial rectus muscle (blank yellow arrow), conjunctiva (blank orange arrow), Tenon's capsule (blank red arrow), and sclera (red star) in relation to the displaced encircling band are depicted
