Posterior Polar Cataract

Daljit Singh classification of posterior polar cataract: Type 1: PPC associated with posterior subcapsular cataract. Type 2: Round or oval discoid opacity with a ringed appearance like an onion with or without grayish spots at the edge. Type 3: Round or oval discoid opacity sharply defined with dense white spots at the edge often associated with weak, thin, or absent posterior capsule. The white dense spots are a diagnostic sign (Daljit Singh sign) of posterior capsule rupture or extreme thinning. Type 4: Combination of the above 3 types with nuclear sclerotic cataract
