Von Herick angle grade '3' of anterior chamber denotes?

Ans. is 'b' i.e., Moderately open ang Classification of anterior chamber angle based on van herick angleof the anterior chamber estimation method Angle grade Angle grade Cornea to angle ratio 4 Wide open angle incapabel of closure. Iris to cornea angular separation equals to 35-45 Anterior chamber depth (shadow) is equal to or greater than corneal thickness 3 Moderately open angle incapable of closure. Iris to corneal angular separation equals to 20-35deg Anterior chamber depth (shadow) is between 1/4 and 1/2 of the corneal thickness 2 Moderately narrow angle closure possible. Iris to corneal angular separation equals to 20deg Anterior chamber depth (shadow) is equal to 1/4 of the corneal thickness 1 Extremely narrow angle, closure chance high. Iris to corneal angular separation equals to 10deg Anterior chamber depth (shadow) is equal to less than 1/4 of the corneal thickness 0 Basically closed angle. Iris to corneal angular separation is 0 Anterior chamber depth (shadow) is nil or only a very narrow slit
