Figure 1 - Right eye

Figure 2 - Left eye

A 22-year-old male presented with complaints of itching of the eyes that was diagnosed and treated as allergic conjunctivitis. An incidental finding is seen as shown in the figures above.

1. Given that there was no refractive error, the eyes were aligned, and the patient had normal stereo acuity, what would you consider a possible visual acuity?

a -- 6/6 in both eyes

In spite of what looks like obstructive bands obstructing the pupil, this young man had normal 6/6 vision in each eye.  This good level of visual acuity is not uncommon in cases like this (see Question of the Week, Mar. 9, 2004).  This child had relatively good vision in spite of a pupillary membrane and moderate mental retardation that was unrelated to the pupil anomaly.

2. What is the most likely diagnosis?

c -- persistent pupillary membrane

This is an example of persistent pupillary membrane. This condition can be associated with other conditions -- Marfan syndrome, for example -- but it frequently presents as an isolated finding in an otherwise normal patient who demonstrates surprisingly good vision.

3. In a case like this, what would be the most likely treatment?

a -- none; just observe

No treatment is required for this condition.  Over the course of time the bands may rupture spontaneously.  Whether they do or not, vision will remain good.  Any attempt at treatment could cause complications such as cataract and hyphema.

* This case was submitted by Dr. Addis Tenkit Woldehanna of Jimma University, Ethiopia.
