… excitation of surface plasmons (SPs) can be used to obtain optical and geometrical parameters of specific layers in multi-layered thin film systems. The optimum coupling phenomenon between incoming p-polarized light and SPs appears as a minimum in the reflectance that is calculated using a standard matrix formalism. Th …
… rpose: The purpose of this study is to determine the effect of phacoemulsification cataract extraction on measurement of retinal nerve fiber layer and optic nerve head parameters using spectral domain optical coherence tomography. Material and methods: A prospective, hospital-based study of 100 patients of 40 years of …
Purpose: An assessment of variation in Macular Volume and RNFL Thickness in myopes using OCT, and their significance for early diagnosis of Primary Open Angle Glaucoma(POAG). Materials and method: Total of 122 eyes of 61 Indian Myopic subjects of both sex and various age groups underwent retinal nerve fiber layer thick …
… dy aimed to evaluate the long-term effect of panretinal photocoagulation (PRP) on the retinal nerve fiber layer (RNFL) in patients with proliferative diabetic retinopathy (PDR). Methods: This was a prospective longitudinal cohort study examining 42 eyes of 42 patients with PDR undergoing PRP. Peripapillary RNFL thickne …
… ipants in the study were 46 patients diagnosed with iERM, who underwent PPV. Best-corrected visual acuity measurement and spectral domain-optical coherence tomography (OCT) were performed at baseline (preoperatively), and at months 6 and 12 postoperatively. Demographic characteristics and OCT parameters were assessed a …
… en-angle glaucoma (POAG) is the most common. Although perimetry is the gold standard, retinal nerve fiber layer (RNFL) thickness by spectral-domain optical coherence tomography (SD-OCT) has proved reliable in the detection of pre-perimetric glaucoma. There is preferential involvement of various sectors of the peripapil …
… p volume (P = 0.001), mean cup depth (P = 0.015), maximum cup depth (P < 0.001), mean retinal nerve fiber layer (RNFL) thickness (P < 0.001) at 1 year of follow-up, and remained significant in all at 4 years of follow-up, whereas there was no significant difference in any of the optic disc parameters in the participant …
Purpose: The purpose of this study was to assess the retinal nerve fiber layer (RNFL) thickness in patients with pseudoexfoliation (PXF) and to correlate it with anterior segment parameters such as intraocular pressure (IOP), central corneal thickness (CCT), pigments in angle structures, and grades of PXF.
