An 18-year-old male presented with bilateral anterior blue dot [Figure 1]a with posterior coralliform cataract [Figure 1]b and [Figure 1]c. Blue dot cataracts are associated with mutation in CRYBB2 gene coding for crystallin beta B2.[1] Coralliform cataract is a rare congenital cataract and characterized by stellate opacities; it is associated with mutation in the CRYGD gene coding for crystallin gamma D.[2],[3],[4] Colour vision was defective and fundus examination showed bilateral temporal disc pallor [Figure 1]d. Dilated evaluation is essential in cases of blue dot cataract to rule out other associated forms of cataract and disc evaluation with color vision is a must in such cases.
