Space Dimension Deficiency - Local Absent of IPB - Lx - (psp)

How to identify a space deficiency or space risk under this partial atrophy inner pupillary border structure ?

Space Risk is measured in various range of 5', 8', or 10' and above degree along with inner pupillary border tissues. A sectional absence of inner pupillary border tissues, where the gap or space dimension is more than 10' and local absent is within 10', both condition can be counted as Space Risk. We have to make sure that a local or sectional IPB, the micron or diameter must be in zero degree so as to fulfill the Space Risk requirement. We will explore more about Space Risk in term of local or sectional introflession, extroflession of IPB.
