    Purpose. A clinical case demonstrating surgical reconstruction of the pupil for bilateral Peters anomaly.

    Material and methods. Patient F., 20 years old. Complaints of vision problems in the left eye. Left eye: microcornea (up to 7–8 mm), the anterior chamber is small, uneven, multiple iridocorneal adhesions at 2.5 and 7 o’clock. The pupil is narrow – 1.0 mm, round, ectopic 2.2 mm upward from the optical center of the cornea, posterior stromal circular synechia, no pupillary reaction to light and mydriatics.

    Results. A tunnel corneoscleral incision with a width of 2.0 mm was formed at 9 o’clock, as well as 2 paracenteses: at 2 and 6 o’clock. Through the local zone of absence of posterior synechiae and residual native pupillary opening (1.0 mm), a 0.6 mm spatula was placed under the plane of the iris, and a posterior synechiotomy was performed. Then, using 25G scissors, the existing pupillary opening was expanded to 4.2 mm in the area of its planned localization. At the end of the operation, the viscoelastic was washed out of the anterior chamber and standard sealing of surgical approaches was performed. The next day the patient noted an improvement in the brightness of the visual image perceived by the eye, and the visual field expanded.

    Conclusion. The presented clinical case demonstrated the possibilities of surgical dilation of the pupil when it tends to be completely closed in an eye with congenital Peters anomaly.
