A series of gonioscopy photographs to illustrate the pectinate ligament dysplasia (PLD) grading system used. The grading system has been applied assuming the photographs are representative of the entire 360° of iridocorneal angle (ICA) in each case. a Normal appearance of the ICA and pectinate ligament. Unaffected (grade 0). b Approximately 15 % of the ICA is affected by abnormally thickened pectinate ligament fibres. Mildly affected (grade 1). c Approximately 25 % of the ICA is affected by pectinate ligament ‘sheeting’. Moderately affected (grade 2). d Approximately 75 % of the ICA is affected by pectinate ligament ‘sheeting’. Moderately affected (grade 2). e Over 90 % of the ICA is affected by ‘sheeting’. Severely affected (grade 3
