Purpose To evaluate benefit of performing central 10‐2 visual field (VF) in association with 24‐2 VF in glaucomatous or glaucoma suspect patients.
Methods 20 glaucoma suspect (Mean Deviation MD=0.19±0.8dB) and 48 glaucomatous eyes (MD=‐2.33±1.9dB) with normal central 24‐2 VF were included. Patients without macular pathology underwent a complete ophthalmological examination and a reproducible VF testing (Humphrey Field Analyser, SITA standard 24‐2 and 10‐2, Carl Zeiss Meditec) and analyze of ganglion cell inner plexiform layer and of retinal fiber layer thickness by Cirrus HD‐OCT.
Results Central 10‐2 VF detect a central defect in 15 eyes (22%). In glaucoma suspect group, a defect was detected by 10‐2 VF whereas 24‐2 VF was normal for 2 patients (10%). In glaucomatous group a central 10‐2 VF defect missed by 24‐2 VF was detected in 7 patients (15%). An extended central 10‐2 VF defect associated with a suspect or a small paracentral 24‐2 VF defect was reported for 6 glaucomatous patients (13%).
Conclusion Central VF defect may be missed by 24‐2 VF analyze. Central 10‐2 VF seems to be useful in glaucoma suspect and in glaucomatous eyes for a better detection of early central functional defect.
PurposeTo compare the intraocular pressure (IOP) measurements and reproducibility of the new ICare Home® rebound tonometer (RT) with Goldman applanation tonometer.Methods36 healthy eyes of 36 patients were enrolled. Three IOP measurements were performed with ICare Home by an ophthalmologist (RT‐O) then by the patient (RT‐P), and with GAT and non‐contact tonometry (AIR). All of the subjects underwent an examination including: slit lamp examination, keratometry, and optical measurements of ocular axial length and central corneal thickness.ResultsResults of mean IOPs were 16.3 ± 4.8 mmHg (RT‐O), 16.2 ± 4.7 mmHg (RT‐P), 15.1 ± 2.6 mmHg (GAT) and 16.0 ± 2.9 mmHg (AIR). There was no statistically difference between the 4 methods with random one‐way ANOVA or repeated measures (P = 0.09) and no difference between each couple of methods after Bonferroni correction for multiple comparisons. Correlation between the tonometers were: r = 87.4% between RT‐O and RT‐P, r = 63.4% between RT‐O and GAT and r = 65.0% between RT‐P and GAT. The intraclass correlation coefficients (ICC) were 0.924 for RT‐O, 0.854 for RT‐P and 0.887 for GAT. Bland Altman plots showed a good agreement between the different methods.ConclusionsIOP measurements with ICare Home by the patient or the ophthalmologist were well correlated to GAT without statistically significant differences. Reproducibility was good and with a good agreement between the differents methods of measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
