Aphakic visual fields by automated perimetry.
Accurate testing of the visual field of aphakic patients is demanding due to the optical distortion induced by high plus corrective lenses. This testing procedure can be improved by using an aspheric contact lens instead of a full-aperture loose trial lens. We found that the contact lens enhances the ability of the pattern-deviation printout of the Statpac analysis to identify glaucomatous visual field abnormalities in program 30-2 of the Humphrey Visual Field Analyzer.

Cataract following radial keratotomy.
An intumescent cataract developed 16 weeks after radial keratotomy in a 31-year-old man. Corneal perforation was documented at the time of surgery, but no direct injury was noted to the lens capsule. Visual acuity decreased to hand motions during a four-month course. Successful extracapsular cataract extraction occurred seven months following the original radial keratotomy. Soft contact lens correction of aphakia recovered a visual acuity of 6/6.

Visual field status in the management of chronic angle-closure glaucoma.
A retrospective analysis of the case histories of 40 patients with chronic angle-closure glaucoma yielded 31 eyes without visual field loss and 26 eyes with field loss. Peripheral iridectomy was highly successful in cases without field loss. Trabeculectomy was significantly more successful (93%) than iridectomy (64%) in treating cases with field loss. It is suggested that the choice of surgical procedure in this syndrome be dictated in part by the character of the visual field.

Surgical decisions in chronic angle-closure glaucoma.
A retrospective study of 57 eyes with chronic angle-closure showed that eyes with visual field loss are less likely to be improved by iridectomy than those without visual field loss in the presence of visual field loss, trabeculectomy achieved more satisfactory control of glaucoma than did iridectomy, and there was no noticeable difference in surgical complications between iridectomy and trabeculectomy in this small series. It is suggested that iridectomy is indicated for most cases of chronic angle closure without visual field loss, especially if the pressure is medically controllable. In the presence of visual field loss, iridectomy is usually a wise choice if medical control is easily achieved preoperatively. However, trabeculectomy might be the best choice in most patients with visual field loss and medically uncontrolled pressure, regardless of the gonioscopic findings.

Optic disk topography and visual field defects in patients with increased intraocular pressure.
One hundred one eyes of 54 ocular hypertensive patients were studied to determine the value of optic disk evaluation in predicting the presence or absence and the location and type of visual field defects by means of binocular slit-lamp examination and projected 35-mm monocular color slides. We suspected visual field loss erroneously in only one patient, and failed to detect ten (16%) of 61 eyes with field defects. An examiner experienced in slit-lamp evaluation of the optic disk can accurately predict the presence, absence, and location of field defects in most cases by stereoscopic evaluation of disk topography.
