purpose : this study was designed to assess and compare the thickness of the peripapillar retinal nerve fiber layer (rnfl) in amblyopic and normal eyes in unilateral strabismic ambelyopia using scanning laser polarimeter. methods : scanning laser polarimetry was performed on 17 patients with unilateral strabismic amblyopia who had an absence of neurologic diseases or glaucoma with a minimum age...

Purpose. To compare the postoperative changes of the retinal nerve fiber layer (RNFL) thickness in patients with macular holes (MHs) treated with vitrectomy with indocyanine green- (ICG-), brilliant blue G- (BBG-), or triamcinolone acetonide- (TA-)assisted internal limiting membrane (ILM) peeling. Methods. Sixty-one eyes of 61 consecutive patients with MHs were studied. Each eye was randomly se...

purpose : to compare retinal nerve fiber layer (rnfl) profile in subjects with myopia and emmetropia using gdx variable corneal compensator (vcc) methods : besides ophthalmologic standard examination (refraction, visual acuity and slit-lamp examination, applanation tonometry, and funduscopy), perimetry and scanning laser polarimetry (slp) were performed. 171 healthy age-matched subjects with lo...

PURPOSE To determine the degree of correlation between spatial characteristics of the retinal nerve fiber layer (RNFL) birefringence (Delta n(RNFL)) surrounding the optic nerve head (ONH) with the corresponding anatomy of retinal ganglion cell (RGC) axons and their respective organelles. METHODS RNFL phase retardation per unit depth (PR/UD, proportional to Delta n(RNFL)) was measured in two c...

Objective The aim is to compare the retinal nerve fiber layer (RNFL) thickness of longitudinally extensive transverse myelitis (LETM) eyes without previous optic neuritis with that of healthy control subjects. Methods Over 20 LETM eyes and 20 normal control eyes were included in the study and subjected to optical coherence tomography to evaluate and compare the RNFL thickness. Result Signif...

PURPOSE To evaluate the ability of frequency domain optical coherence tomography (fd-OCT) to estimate retinal neural loss in eyes with Alzheimer's disease (AD). We also verified the existence of a correlation between AD-related cognitive impairment and macular and peripapillary retinal nerve fiber layer (RNFL) thickness measurements. METHODS fd-OCT scans were obtained from 45 eyes of 24 patie...

BACKGROUND Headache is one of the most disturbing symptoms with common neurological signs. Variations in optic nerve perfusion quality or retinal microcirculation may end up in ganglion cell damage in patients with migraine. METHODS Sixty patients diagnosed with migraine and thirty normal individuals were evaluated in groups including migraine with aura, migraine without aura and controls. Re...

OBJECTIVE To calculate the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of measurements of the retinal nerve fiber layer using the Stratus optical coherence tomography in glaucoma subjects with visual field defects on achromatic perimetry as the gold standard. STUDY DESIGN Comparative cross-sectional. PLACE AND DURATION OF STUDY Outd...

OBJECTIVE To study how customizing the peripapillary scan diameter on the basis of optic nerve head (ONH) diameter affects retinal nerve fiber layer (RNFL) thickness measurements using Stratus optical coherence tomography (OCT). METHODS Retinal nerve fiber layer was examined using 1 fixed-diameter circular scan (3.4 mm) and 2 customized-diameter scans (at 0.5 mm and 1 mm from the ONH edge) in...
