On distant direct ophthalmoscopy, an asymmetric red reflex with an inferior notch [Figure 1]a was found in the left eye of a 30-year-old woman with irido-lenticular coloboma [Figure 1]b. The notch represents an area of localized high refractive error due to lenticular astigmatism and is seen above the margin of lens coloboma.[1],[2],[3] The other eye was normal [Figure 1]c. Absence of zonules in a lens coloboma causes localized swelling of the lens due to loss of this stretch effect. This swelling of the lens causes irregular lenticular myopic astigmatism giving a different glow as compared to the rest of the lens.[4],[5]
