“…A family history of glaucoma in first‐ and second‐degree relatives was taken. The visual fields were tested with the competer 350 automated perimeter (Bara Elektronik AB), using a supraliminal threshold‐related test logic, measuring the light sensitivity of 68 locations in the central 20° (Heijl, 1985). Abnormal or unreliable tests were repeated.…”

Purpose To study predictors of open‐angle glaucoma (OAG) in newly diagnosed patients detected in clinical practice in a defined population and to estimate the frequency of normal‐tension glaucoma (NTG). Methods Predictors of OAG were analysed in a case–control study, nested in a cohort of 481 people, 55–84 years of age, in two rural districts in Sweden, examined at the Eye Department in Tierp from 1988 to 2003. To make the sample complete, 63 residents first examined at the Uppsala University Hospital (UUH), 60 of whom were identified with the help of registers, were invited to attend the study. In this way, the cohort included 544 individuals. Automated perimetry was used to find cases of OAG. Results In people first examined in Tierp, incident OAG was found in 99 subjects. Of these cases, six were diagnosed with NTG. Increased intraocular pressure (IOP), higher age, male sex, a positive family history, pseudoexfoliation (PEX), and haemorrhages of the optic disc were associated with OAG. In a logistic regression model including PEX, every increase in IOP by 5 mmHg increased the risk for OAG four‐fold (odds ratio 4.04; 95% confidence interval 2.91–5.62). The effect of PEX was essentially mediated by increased pressure. The inclusion of the 63 subjects first examined at the UUH had no impact on the results. Conclusion In this study on patients aged 55–84‐years old in clinical practice in Sweden, increased IOP was strongly associated with incident OAG, while NTG was a rare finding.

This is a prospective study of 82 newly discovered patients with simplex or capsular glaucoma from two centres, collected between 1984 and 1989 and selected at random for primary treatment by either laser or pilocarpine. Preliminary two-year follow-up shows that primary laser treatment gives a significantly higher number of patients where the intraocular pressure is successfully controlled. Primary argon laser trabeculoplasty has been carried out in 40 patients. The first treatment was given to either the upper or to the lower half of the trabecular meshwork. In the second treatment after one month the other half was treated. In both groups the first treatment gave the highest pressure reduction. The somewhat higher pressure reduction after upper treatment versus lower was insignificant. The degree of trabecular pigmentation did not influence the two month follow-up result, neither did the type of glaucoma. Of the eyes treated with laser, peripheral anterior synechiae could be seen in 18%. Acute intraocular pressure rises greater than 5 mmHg occurred in 21% of the eyes after the first treatment and in 37% after the second treatment. Pressure rises greater than 10 mmHg occurred in 5% after the first and in 10% after the second treatment. No pressure-lowering substances were given. Considering that 16% of the eyes had an intraocular pressure that was higher than baseline pressure even 6 h after either first or second treatment, it is recommended that a pressure-lowering medication on the day of treatment should be administered.

“…A utomated achromatic threshold perimetry has served as a durable cornerstone of glaucoma-related patient care for over 4 decades and remains the standard of care for visual field (VF) measurement in glaucoma. 1 The most commonly used VF testing methodology uses a grid of test points, spaced ~6 degrees apart, which is centered on fixation and extends 24 to 30 degrees in each direction (24-2 test pattern). By using various thresholding algorithms to determine relative visual sensitivity for each of the grid's test locations, this testing approach has been shown to provide valid measurements of glaucomatous VF loss, thereby offering critical data for aiding diagnosis, 2,3 monitoring progression, 4 informing disease staging, 5 and guiding treatment decisions.…”

Precis: Using standard glaucoma structural and functional tests, clinicians accurately predicted the presence/absence of 10-2 glaucomatous visual field (VF) loss in 90% of the eyes in this study.Purpose: To investigate how well clinicians with variable experience can predict the presence and location of 10-2 VF loss using structural and functional data that are routinely obtained for glaucoma assessment.Methods: Within a test set of 416 eyes (210 subjects) who were diagnosed glaucoma suspect or primary open-angle glaucoma (with most eyes having mild disease), 6 clinicians were asked to predict the presence and hemispheric location of 10-2 VF loss using 24-2 VF and spectral-domain optical coherence tomography structural data. Prediction accuracies were calculated for each clinician and compared using the weighted κ-statistic. Receiver operating characteristic analyses were used to evaluate models for predicting 10-2 VF loss.Results: Among the 6 clinicians, mean (range) accuracy, false negatives, and false positives for predicting presence/absence of 10-2 VF loss were 90% (87% to 92%), 4.7% (2.4% to 7.0%), and 5.4% (1.7% to 7.5%) respectively. The mean (range) weighted κ-statistic was 0.75 (0.64 to 0.83), suggesting good or very good inter-rater agreement between examiners. Mean accuracy for correctly predicting hemispheric location was 73% (range, 65% to 82%) with the most common error occurring in eyes with both superior and inferior 10-2 VF defects in which one hemisphere was correctly identified but the other missed.Conclusions: In this study, the presence/absence of 10-2 glaucomatous VF loss was highly predictable using standard functional and structural clinical metrics. These findings suggest that 10-2 VF testing is not needed to reliably recognize and confirm central VF involvement in most eyes with glaucoma. Whether error related to identifying second hemisphere involvement in 10-2 VF loss is important requires further study.
