The ISNT Rule and Differentiation of Normal From Glaucomatous Eyes. Interobserver variability occurs when two or more observes vary in their evaluation on one common entity. This discrepancy between the cup and pallor becomes more apparent when saucerization is present. The pallor associated with glaucomatous changes in the cup chronologically follows the thinning of the neuroretinal rim and its color. 2015;10:e0120634. This scale takes into account.

This is especially important if thinning is noted inferiorly and superiorly as these areas are usually the first to change in glaucoma. Therefore, development of the positive dot sign requires a certain degree of cupping and exposure of the lamina cribrosa on the vitreous surface.

Lamina cribrosa depth in different stages of glaucoma. Vertical and horizontal air flow models. The “lamina dot sign” was originally described as visible lamina pores adjacent to an area of focally narrowed neural rim.2 While increasing visibility of lamina pores over time may suggest progressive glaucoma, 3 our cross-sectional data suggest lamina pore visibility per se is a stronger sign of a large cup-disk ratio than glaucoma. However, sloping is not absence of rim and this should be confirmed in all cases, especially in myopes. Ophthalmology. Recent technological advances in the field of glaucoma relating to optic nerve imaging can help assist ophthalmologists in diagnosing and monitoring glaucoma in their patients. discussion 829-30.

By evaluating the SDP, patients were classified into laminar dot sign (LDS) and non-LDS groups. Laminar flow is mostly utilized in lab-on-a-chip devices. Any violation of the ISNT rule raises suspicion of glaucomatous changes. Why we use 3M TM Dual Lock. In particular, patient with normal tension glaucoma are at increased risk (between 3 to 5 times more likely) to have them. However, care needs to be taken if disc hemorrhages are noted as the differential includes other causes such as posterior vitreous detachment, trauma, hypertension, or use of anticoagulation medications like coumadin.

Laminar and prelaminar tissue displacement during intraocular pressure elevation in glaucoma patients and healthy controls. J Glaucoma. To investigate the association between the laminar dot sign (LDS) and the deep optic nerve head (ONH) structure in eyes with primary-open-angle glaucoma (POAG). This is especially important when facing the common dilemma of diagnosing glaucoma or monitoring its progression in cases that are not obvious. Intraobserver variability arises from the variation of evaluation from one observer about the same entity. The four quadrants of the neuroretinal rim follow a characteristic pattern of thickness in normal individuals as described by the ISNT rule. By multivariate analysis, thin PTT was significantly associated with the presence of LDS (odds ratio = 0.939, P < 0.001). Girard MJ, Tun TA, Husain R, Acharyya S, Haaland BA, Wei X, et al. Therefore, close attention should be given to the areas where vessels appear to be kinking in addition to that of pallor as the former would more accurate in identifying the cup.
