Objective. To compare the equivalent optic nerve head (OHN) parameters obtained with confocal scanning laser ophthalmoscopy (HRT3) and spectral-domain optical coherence tomography (OCT) in healthy and glaucoma patients.Methods. One hundred and eighty-two consecutive healthy subjects and 156 patients with open-angle glaucoma were divided into 2 groups according to intraocular pressure and visual field outcomes. All participants underwent imaging of the ONH with the HRT3 and the Cirrus OCT. The ONH parameters and the receiver operating characteristic (ROC) curves were compared between both groups.Results. Mean age did not differ between the normal and glaucoma groups (59.55 ± 9.7 years and 61.05 ± 9.4 years, resp.;P=0.15). Rim area, average cup-to-disc (C/D) ratio, vertical C/D ratio, and cup volume were different between both instruments (P<0.001). All equivalent ONH parameters, except disc area, were different between both groups (P<0.001). The best areas under the ROC curve were observed for vertical C/D ratio (0.980 for OCT and 0.942 for HRT3;P=0.11). Sensitivities at 95% fixed-specificities of OCT parameters were higher than those of HRT3.Conclusions. Equivalent ONH parameters of Cirrus OCT and HRT3 are different and cannot be used interchangeably. ONH parameters measured with OCT yielded a slightly better diagnostic performance.

Abstract Purpose: To describe the eyes with vitreous floaters and to analyze the development of acute symptomatic posterior vitreous detachment (PVD). Methods: A retrospective review of medical records was performed on patients with the vitreous floater developed for the first time of their life. Peripapillary vitreous opacity (pVO) was searched in Ultra-wide field (UWF) scanning laser ophthalmoscopy and PVD stage was assessed through spectral-domain optical coherence tomography (SD-OCT). Results: 196 patients (55 males and 141 females), who were 58.4(±9.1) on years old, visited a retinal clinic 9.4 (±9.1) days after they experienced vitreous floaters. (pVO) was noticed in 62.2% at UWF and PVD was initiated more than 94.3%. Symptomatic eyes had more prevalence of peripapillary vitreous opacity (63.2% vs 18.4%, p=0.040) and more advance staged PVD (p<0.001) than symptom free eyes. Eyes with floaters were more myopic (-0.7±2.2D vs -0.5±1.9D, p=0.02), and had lower IOP (14.7±3.2mmHg vs 15.2±3.0mmHg, p=0.02) than the other symptom free eyes. Conclusion: In patients with first floater symptoms, PVD was in progress in most of the eyes not only the symptomatic eyes but also on the contralateral symptom free eyes. Eyes with vitreous floaters were more myopic and had lower IOP than the opposite symptom free eyes.
