Abstract

AlM and PPM are congenital iris anomalies in which
fine or thick iris strands arise form the collarette and
obscure the pupil. AIM, which is also called iris
duplication, closely resembles the normal iris tissue in
color and thickness and presents a virtual second
pseudopupil aperture in the centre while PPM even in
its extreme forms presents as a translucent or opaque
membranous structure that extends across the pupil
and has no pseudopupil. laser treatment or surgery is
used to clear the visual axis and optimize visual
development. Surgical intervention is reserved for
large, dense AlMs and PPMs. Our patient, a 25 year
old male, has come with bilateral dense AlM, bilateral
compound hyperopic astigmatism, BCVA OD =6/24,
BCVA OS = 6/12, I0P re = 18 mmHg le=16 mmhg. To
improve the visual acuity of the patient we decided to
do a bilateral membranectomy, restoring in this way
transparency of the visual axis. After surgery, the
visual acuity improved to BCVA OD= 6/9, BCVA
OS=6/9.
