Abstract Details

Purpose:

To present a case of recurrent episodes of monocular vision blurring during breastfeeding in a 35-year-old woman, due to pigment cell dispersion from an iris strand.

Setting:

1st Department of Ophthalmology, National and Kapodistrian University of Athens, G. Gennimatas Hospital

Methods:

Case presentation. A 35-year-old presented in the emergency department reporting blurred vision in the left eye. It was the third such episode during the last month. All episodes lasted for about 4 hours and took place during night hours when she woke up to breastfeed her 1-month-old infant. Full ophthalmology examination was performed, as well as visual field testing, blood tests, brain and orbital MRI, transthoracic echocardiography and a Duplex ultrasound of the carotid and vertebrobasilar arteries.

Results:

Visual Acuity was 20/20 in both eyes unaided. Slit lamp examination of the left eye revealed 26-50 pigmented cells in field / 3+ (SUN working group grading) in the anterior chamber (AC) and a thin pigmented strand of iris spanning from one side of the pupil crossing towards the other side, connected at a single point to the anterior capsule of the lens, with pigment cells flowing linearly from the point of connection to the lower part of the AC. Examination of the right eye was unremarkable.

Conclusions:

The episodes of blurred vision were attributed to the flow of pigmented cells from the iris strand. The increased pupillary diameter in pregnancy and in the postpartum period as well as ocular changes due to hormonal changes that take place in the same time can be used to interpret these episodes.
