Purpose:

we aimed to report a new complication of cataract surgery.

Methods:

our case was visited at Feiz eye hospital. At the presentation, after taking a complete history, ocular examinations including best corrected visual acuity, pupillary reflex, red reflex, gaze movements and slit lamp examination were performed.

Results:

Her best visual acuity was 20/20 OD and 16/20 OS. Pupillary reflex was normal with no relative afferent defect. Red reflex was 10/10 OD and 9/10 OS. Extraocular movements were normal OU. On slit lamp examination, both eyes were pseudophakic. In the left eye, Mild corneal edema; trace reaction and a residual 25% air bubble on upper side of anterior chamber (AC) were seen. On peripheral indirect fundoscopy, a bubble could hardly be seen on uppermost far periphery of the left retina.

Conclusion:

Herein, for the first time, we describe a symptom which has not been previously described following cataract surgery. Noting the dark ring was annoying and intimidating to the patient and was completely postural, occurring only when bowing forward and disappearing when holding head up high. Existence of a bubble in PC of a patient with AC formed with air and no history of VL could be simply explained by immigration of the air from AC to PC through a possible zonular defect.
