Representative slit lamp photographs and tomographic images (case 8). a Preoperative photograph shows inferotemporal subluxation of the intraocular lens (arrow). b Preoperative gonioscopic image of the iridocorneal angle shows a distinctive pigmentation in the trabecular meshwork (arrow). c Slit lamp photograph before iridotomy shows a concave iris (arrowheads). d Slit lamp photograph before iridotomy shows the apposition between the iris and intraocular lens optic (arrows), indicating the presence of reverse pupillary block. e Slit lamp photograph taken immediately after iridotomy shows a flat iris (arrowheads). f Slit lamp photograph taken immediately after iridotomy shows the space between the iris and intraocular lens optic (arrows), indicating recovery from reverse pupillary block. g Tomographic image taken before iridotomy show a concave iris configuration and wide anterior chamber angle. h Tomographic image taken immediately after iridotomy shows a flat iris and a narrower anterior chamber angle. The arrowheads and white line in d and f indicate the posterior surface of the intraocular lens. (Ax = angle, Co = cornea, Ir = iris, Ma = mirror artifact)
