Eyelids & the Anterior Segment:
The above picture shows the left eye of a 60 year-old man who had had a right phacoemulsification and implant two weeks earlier.
a. What is the diagnosis?Pupillary capture.
It occurs when a part of the optic moves anterior to the iris. Its incidence is increased in:
- pupillary dilatation during the early postoperative period
- use of lenses with non-angulated haptics
b. What complications can arise?In the majority of patients, complications do not occur.
The possible complications are:
- cosmetic defect with eclliptical shaped pupil especially in patients with light iris
- astigmatism if the lens were significantly decentred
- low grade inflammation with uveitis and possibly cystoid macular oedema
- pupillary block glaucoma rarely occur
c. What are the treatment options?Treatment may not be needed if the patients were asymptomatic. Repositioning of the lens can be achieved with:
- medical treatment. This may be achieved with intense dilatation with the patient in a supine position. When the lens falls back, the pupil is constricted. This needs to be done in the early post-operative stage before posterior synechiae occurs between the iris and the posterior capsule
- surgical repositioning (which was performed in this patient)
