Abstract Purpose To estimate the link between the thickness of retinal nerve fiber layer (RNFL); utilizing optical coherence tomography (OCT) and corresponding retinal sensitivity changes; utilizing visual field (VF) perimetry, in cases of ocular hypertension and early glaucoma. Methods Thirty patients (60 eyes) were gathered for this prospective, cross-sectional study. They were categorized into two groups. Group I comprised 30 eyes (15 patients) having ocular hypertension. Group II comprised 30 eyes (15 patients) early recognized as primary open angle glaucoma. Each patient underwent a thorough ophthalmologic examination, OCT for RNFL thickness estimation using quick RNFL thickness protocol and VF testing using automated perimetry (G2 program, central 30–2 threshold protocol). Pearson’s correlation was premediated between thickness of RNFL and VF indices. Results Significant connections between the thickness of temporal area of RNFL and mean sensitivity (MS), mean defect (MD) and loss of variance (LV) indices of VF (r = 0.533, -0.431, -0.388; P < 0.01, respectively) were noticed in patients having ocular hypertension. Additionally, a significant link between the thickness of the temporal area of RNFL and MS index of VF (0.441; P < 0.05) was noticed in patients with early POAG. Otherwise, there were no significant links between indices of VF and other areas of RNFL thickness in both groups. Conclusion Average RNFL thickness is certifiably not a dependable index for early determination of glaucoma or for the follow-up of ocular hypertension and POAG. Segmental RNFL thickness (especially temporal) appears to be a more dependable index. Profound structural modification with OCT test comprises an imperative sign of early utilitarian changes, regardless of whether they are not yet recognized with perimetry. The MS index of VF is by all accounts sensitive for the follow-up of ocular hypertension.

Purpose To correlate functional damage over time detected by standard automated perimetry (SAP) and frequency doubling technology (FDT) with central corneal thickness (CCT) in patients with ocular hypertension (OHT). Methods Seventy-eight OHT patients underwent CCT measurements, SAP, and FDT (the latter two also after 12 and 18 months). Patients were divided into three equally sized groups of 26 patients each: thin (<540 üm), normal (540–580 üm), and thick cornea (>580 üm). The frequency of abnormal FDT and SAP results was analyzed over time (Pearson χ2 test). Results Six of 26 patients with thin corneas (23.1%) presented an abnormal FDT test at baseline, compared to 1 of 26 (3.8%) in the normal thickness cornea group and 1 of 26 (3.8%) in the thick cornea group. After 12 months, the abnormal FDT tests were as follows, respectively: 9 of 26 (34.6%), 2 of 26 (7.7%), and 2 of 26 (7.7%). For SAP the abnormal results were as follows, respectively: 8 (30.1%), 5 (19.2%), and 2 (7.7%). After 18 months, the abnormal FDT tests were as follows, respectively: 16 (61.5%), 5 (19.2%), and 5 (19.2%). For SAP, the abnormal results were as follows, respectively: 10 (38.5%), 5 (19.2%), and 2 (7.7%). Conclusions OHT patients with thinner corneas have a greater risk of developing functional damage over time.

Abstract Purpose To review the evidence on the usefulness of the multifocal visual evoked potential (mfVEP) test in patients with optic neuritis (ON) and/or multiple sclerosis (MS). Methods We critically review key published evidence on the use of mfVEP in ON/MS patients and its association with other functional and structural tests. Results Multifocal VEP tests are useful in detecting abnormality in patients with ON/MS and monitor the progression of lesions (remyelination, atrophy). In addition, mfVEP has good correlation with conventional visual evoked potential (VEP), standard automated perimetry, optical coherence tomography and magnetic resonance imaging. In patients with ON, mfVEP might be useful in predicting the risk of conversion to MS.

Purpose To test the capability of rarebit perimetry (RP), a recent non-conventional perimetric technique, in detecting early functional damage in subjects with ocular hypertension (OHT) and to compare RP findings with those obtained by frequency-doubling technology (FDT) perimetry. Methods Thirty patients with OHT were matched with 30 healthy subjects. All were tested with RP and FDT. Frequency-doubling technology mean deviation (MD) and pattern standard deviation (PSD), as well as RP mean hit rate (MHR), of the two groups were analyzed. The agreement between the two techniques was tested by Kappa analysis. Results In the OHT group the mean (SD) FDT MD was 0.5 (2.1), the mean (SD) FDT PSD was 4.2 (1.6), and the mean (SD) RP MHR was 81.4 (6.7). In the control group, corresponding values were mean (SD) FDT MD 1.1 (1.4), mean (SD) FDT PSD 3.0 (0.3), mean (SD) RP MHR 96.2 (2.0). The differences between the two groups were not significant for the studied indexes. Eleven (36.6%) out of the 30 OHT eyes had abnormal RP results; 12 (40.0%) eyes had abnormal FDT results. Five (16.6%) eyes had abnormal RP and FDT findings. Only 1 eye (3.3%) in the control group had abnormal RP results and 3 eyes (10.0%) had abnormal FDT results. RP and FDT showed a moderate agreement (Kappa = 0.43; 95% CI: 0.42 to 0.51). Conclusions RP and FDT showed VF defects not shown in standard automated perimetry in the OHT group. This may be indicative of an increased risk in developing glaucoma, even if a gold standard for detecting subtle defects is not currently available. RP has the additional advantage of not requiring any expensive device to be used. The poor agreement between these techniques in identifying eyes with early damage warrants further investigations. Large longitudinal studies are needed before defining the role of RP in early glaucoma diagnosis.
