Purpose To report three cases of reverse pupillary block after suture of intraocular lens(IOL) to the ciliary sulcus in avitreous eyes. Methods Visual impairment occurred in three eyes of three patients with past surgical history of vitrectomy and suture of IOL to the ciliary sulcus. Their findings of anterior segment showed deep anterior chamber (6000μm~4330μm) with concavity of the intermediate and peripheral iris, compression bonding of the pupil and IOL, and pigmentation of the trabecular meshwork. The diagnosis of a reverse pupillary block was made by opthalmological examinations and additional tests, e.g., ultrasonography and Pentacam®. In all eyes, laser iridotomy(LI) was performed in the superior peripheral iris to eliminate reverse pupillary block. Results As a result, reverse pupillary block was eliminated and the depth of anterior chamber returned to normal (4018μm~3700μm), furthermore, concavity of the iris and compression bonding of the pupil and IOL were disappeared in all eyes. Conclusion In the eyes with past surgical history of vitrectomy and suture of IOL to the ciliary sulcus, reverse pupillary block might occur and LI can be effective.
