Background  

To investigate thickness of the macular ganglion cell complex (mGCC) and circumpapillary retinal nerve fiber layer (cRNFL) in retinal segments without visual field (VF) loss in glaucomatous eyes in which localized VF defects were confined to a single hemifield, using spectral-domain optical coherence tomography (SD-OCT).

Purpose  

To investigate the longitudinal relationship between retinal nerve fiber layer (RNFL) thickness parameters assessed by scanning laser polarimetry with variable corneal compensation (GDxVCC) and visual field parameters obtained with the Humphrey field analyzer (HFA) in patients with glaucoma, and to assess the usefulness of GDxVCC in longitudinal follow-up.

To evaluate the usefulness of automated fundus-oriented small-target perimetry in detecting glaucomatous visual field abnormalities.     

Relationship between visual field loss and contrast threshold elevation in glaucoma

Background  

There is a considerable body of literature which indicates that contrast thresholds for the detection of sinusoidal grating patterns are abnormally high in glaucoma, though just how these elevations are related to the location of visual field loss remains unknown. Our aim, therefore, has been to determine the relationship between contrast threshold elevation and visual field loss in corresponding regions of the peripheral visual field in glaucoma patients.     

Pupillary anomaly masquerading as a glaucomatous visual field defect: a case report

Background  

Patients are often referred to ophthalmologists with focal visual field defects on routine testing, possibly related to a potential diagnosis of glaucoma. However, examination of the individual patient's ocular characteristics as well as facial characteristics may often reveal a cause of the visual field defect.     

Disc photography and heidelberg retinal tomography documentation of reversal of cupping following trabeculectomy

Background  

Reversal of cupping is a widely recognized phenomenon. However, whether or not functional improvement is associated with reversal of cupping is controversial. There has not been any documentation in the literature of reversal of cupping with accompanying Heidelberg Retinal Tomograph (HRT) images and visual field (VF) changes at each time point.

Aim  

(i) To map the spatial distribution of absolute visual field loss (AL) in patients exposed to vigabatrin and to compare the findings with AL in normal individuals, and (ii) to describe the relationship between the major risk factors for absolute loss (gender, age, cumulative dose), and the severity of field loss, expressed as the number of locations with AL per eye.     

Optical coherence tomography shows progressive local nerve fiber loss after disc hemorrhages in glaucoma patients

Background and aim  

The aim of this work is to investigate whether optic disc hemorrhages (ODH) lead to significant loss of nerve fibers at the lesion site over time and whether such a loss is reflected by visual field defects corresponding to the affected nerve fiber bundle.

Backround  

To determine the extent of visual field loss in patients who had required a pars plana vitrectomy secondary to complications of proliferative diabetic retinopathy.     

Early axonal damage detection by ganglion cell complex analysis with optical coherence tomography in nonarteritic anterior ischaemic optic neuropathy

Purpose

To investigate the ability of ganglion cell complex (GCC) analysis by optical coherence tomography (OCT) to detect early axonal damage in nonarteritic anterior ischaemic optic neuropathy (NAION), and to assess the relationship of GCC measurements with visual field defects and function parameters.

Methods

Twenty-two patients with NAION participated in this retrospective case-series study. Patients underwent spectral-domain OCT measurement of retinal nerve fibre layer (RNFL) and GCC average and minimum thicknesses, best-corrected visual acuity, Ishihara test and Humphrey visual field (SITA Standard 24–2). These measurements were recorded in the acute (2–6 weeks after the ischaemic episode) and chronic (≥6 months later) phases. Spearman’s coefficients were used to assess the relationship between GCC thickness and visual field defects.

Results

In the acute phase, none of the patients showed atrophy of the optic disc, while early damage was observed in the GCC average and minimum thickness in 54.54 % and 77.27 % of patients. At 6 months, the rate of patients with RNFL below normal limits increased to 90 % in the RNFL, and 92.85 % and 100 % in the GCC average and minimum GCC respectively. Spearman’s coefficients indicated significant relationships of GCC in the acute phase with visual field index and mean deviation in both acute and chronic phases. A significant correlation was also found with location of the defects.

Conclusions

GCC thickness measurement by OCT is capable of detecting early axonal damage in NAION eyes in the acute phase that cannot be detected by RNFL. GCC defects are significantly correlated with visual field globally and the defect location.
