Ocular hazards of nebulized bronchodilators.

Three cases of pupillary dilatation associated with the development of acute glaucoma, precipitated by the use of nebulized bronchodilators are described. We suggest measures to reduce the risk of this complication.

Soap gets in your eyes.

We present a previously unreported series of five cases of acute angle closure glaucoma associated with watching the Australia soap opera "Neighbours". Two cases were bilateral and associated with watching two episodes of "Neighbours" on the same day. The pathogenesis, and possible role of watching soap operas in the causation of primary angle closure glaucoma is discussed.

[YAG laser treatment in anterior segment disease of the eye].

Three hundred and fifty-two eyes (230 patients) with various diseases were treated with the first China-made YAG laser therapy instruments. The success rate was 100%. Two hundred and seventy-six eyes with primary angle closed glaucoma were treated by peripheral iridotomy. Postoperatively, the IOP was lowered by 0.267 kPa (2.43 mmHg). The dose and frequency of medication could then be lowered. The closed chamber angle index improved. Forty-nine eyes with membranous cataract were treated by posterior capsulotomy: Visual acuity was improved by 95%. The main complications during or immediately after operation were as follows: transient elevation of IOP, hyphema, anterior uveitis and corneal edema. All of these were well controlled.

Pupillary dilation: an eye-opening problem.

Dilation of the pupil is a procedure with both clinical and legal ramifications. Optometrists must be familiar with the requirements of informed consent, which must be met when utilizing dilation on the 4-8 percent of patients with anterior chamber angles that are narrow enough to cause an angle closure. Optometrists also must recognize those circumstances under which pupillary dilation is necessary, both for symptomatic and asymptomatic patients. The correct drug regimen must be selected, whether it is for "routine" pupillary dilation or for a patient with a condition requiring a special drug regimen. Patients with dilated pupils must be appropriately managed, and failure to warn a patient of common and expected side effects may create liability if the failure to warn is the cause of injury. If complications--such as acute angle closure--occur, the optometrist must be prepared to manage the situation so as to minimize the risk of injury to the patient.

Surgical and medical management of patients with narrow anterior chamber angles: comparative results.

We retrospectively reviewed case records of 70 patients (114 eyes) to assess long-term outcome of surgical and medical treatment of narrow anterior chamber angles. Fifty eyes had undergone a peripheral iridectomy, incisional or laser; 64 had been treated medically, without surgery. The two groups were not strictly comparable. (It is assumed but not proven that, since iridectomy was considered necessary in one group and not in the other, the surgically-treated patients were more seriously diseased.) Comparing clinical data obtained at the first visit with data obtained at the last visit, the eyes receiving iridectomies, as compared with those receiving medical treatment alone, showed a greater number of improved anterior chamber configurations (74% vs 28%), had a lower incidence of peripheral anterior synechiae (2% vs 10%), and required fewer glaucoma medications (30% fewer vs 10% fewer). The percentage of eyes with increased intraocular pressure was similar in both groups (36% vs 28%), as was the percentage of those with decreased visual field (17% vs 21%) and decreased visual acuity (66% vs 60%). No significant complications occurred in the eyes receiving laser iridectomies; however, one of the incisionally-treated eyes lost nine Snellen lines of vision.

Bilateral malignant glaucoma.

Two cases of bilateral malignant glaucoma are presented. In one case the condition developed sequentially in the two eyes; pars plana vitrectomy was eventually needed in the operated eye, whereas the condition responded to medical treatment in the fellow eye. In the second case the two eyes were involved simultaneously nearly 1 year after surgery, and the glaucoma responded to medical treatment.

[Method of iris retraction in narrow-angle glaucoma].

A new surgical method for the treatment of narrow-angle glaucoma is suggested, consisting in the following: in sinuso-trabeculectomy the bridge cut from the deep layers of the sclera via a diagonal incision is transformed into triangular flaps that are charged into the anterior chamber for the iris retraction. The new geometry of incisions improves the efficacy of iris retraction and makes the surgery less traumatic.

Glaucoma, Angle-Closure↗

The management of glaucoma in nanophthalmos.

Patients with nanophthalmos are prone to develop a chronic painless type of glaucoma in middle age, probably due to the natural increase in the size of the lens which is already relatively too large for the small eye. Although the underlying mechanism is obscure, a slowly progressive "creeping" chronic angle-closure is postulated, but gonioscopic evaluation is difficult due to the shallow anterior chamber, with grade I and slit angles. Response to medical treatment is poor and miotics may even make the condition worse by producing relative pupillary block and by relaxing the lens zonule. Ordinary glaucoma surgery is to be avoided in nanophthalmos because of the fear of postoperative ciliary-block malignant glaucoma. Periopheral iridectomy performed in five eyes at an advanced stage of the chronic angle-closure did not facilitate glaucoma control in three eyes, and in two eyes in which the operation was combined with posterior sclerotomy, the eyes became blind from vitreous hemorrhage. Lenx extraction in five eyes controlled the glaucoma but was followed by choroidal effusion and nonrhegmatogenous retinal detachements in two eyes and blindness in another eye when combined with a posterior sclerotomy. No firm therapeutic recommendations can be made on the basis of the author's experience in the six reported cases. Conventional medical therapy seems ineffectual even when begun early in the glaucoma. Conventional glaucoma surgery must be performed early, before permanent damage to the outflow mechanism occurs but removal of the lens must be anticipated. The surgeon must also remain aware of the high incidence of serious posterior-segment complications which inexplicably follow glaucoma or lens surgery in nanophthalmos, as described by Brockhurst.

The prediction of glaucoma from ocular biometric data. Part 1. An application of multiple regression analysis.

Two sets of multiple regression equations (prediction systems) were derived from the analysis of ocular biometric data obtained from glaucoma patients (16 open angle; 16 angle-closure) and 75 normal subjects. Discriminant scores were established for both sets of equations which minimised the number of false negatives. One set, the 'Glaucoma Equations' was applied to the data to segregate the glaucoma from the normal subjects. The other prediction system, the 'Classification Equations,' was then applied to the group defined as glaucomatous to discriminate between patients in the angle-closure and open angle categories. The performance of these equations, obtained by comparing the predicted and actual classifications for this sample, was such that between 9 and 12% of false positives and 0 and 3% false negatives were found on the 'Glaucoma Equations' and between 6 and 12% of false positives with no false negatives on the 'Classification Equations.'

Survey of the first-degree relatives of glaucoma patients.

Family histories were taken from 124 index patients, who had presented with either angle-closure or open angle glaucoma to the University Department of Ophthalmology, Manchester, between 1967 and 1972. Their first-degree relatives numbered 886, i.e. siblings, offspring and parents. Relatives were contacted by post and asked to attend for eye examination. Out of a total of 886 relatives, only 187 relatives were actually examined. The reasons for this low attendance rate are discussed; e.g. 423 relatives had already died.

Trabeculectomy: long-term follow-up.

The postoperative course of 309 eyes subjected to trabeculectomy has been studied over a 7-year period. The results have been compiled with regard to effectiveness to maintain a normal range of intraocular pressure with and without postoperative medication. The figures have been assessed in toto and for 3 groups of glaucoma, namely, open angle, chronic angle-closure, and acute angle-closure. Results support those of other reports to show that trabeculectomy gives satisfactory control over the years in a reasonably high proportion of eyes and with relatively few postoperative complications. There is also a small group of combined trabeculectomy with cataract extraction.

Combined cyclodialysis and cataract extraction.

Combined cyclodialysis and cataract extraction was performed on 78 eyes in a consecutive series of 26 years duration. This operation was performed on eyes with severe glaucoma, inadequately controlled on maximum medical therapy, and with a cataract needing extraction. Glaucoma types included open-angle, angle-closure with peripheral anterior synechias, combined open-angle and angle-closure, and secondary to uveitis. Seventy of the 78 eyes had follow-up of six months or more and the results in these 70 eyes were analyzed. In thirteen percent of the eyes in this study the postoperative intraocular pressure was the same or higher than the preoperative level, or reductions of intraocular pressure were not clinically significant. Eighty-seven percent (61 eyes) had a clinically significant lowering of intraocular pressure following the combined procedure. Thirty-nine percent (27 eyes) of the 70 eyes in this study had a tension of 0-14 mm Hg, and 44% (31 eyes) had a tension of 15-20 mm Hg. Intraocular pressure was improved significantly more often in patients over 60 years of age. Resulting intraocular pressures of 14 mm Hg or less were more likely when the cyclodialysis was performed in the lower quadrant. The results of the combined procedure were not significantly influenced by the type of glaucoma involved or by a history of previous glaucoma surgery. Bleeding was a frequent complication, but was not related to resulting intraocular pressure. Other complications were rare. We conclude that combining cyclodialysis with cataract extraction is safe and effective, and is a suitable procedure when there is need for surgery to relieve severe glaucoma, along with a need for cataract extraction.
