| Abstract |
To determine whether: (1) change in lamina cribrosa depth occurs more frequently than change in neuroretinal parameters in glaucoma, and (2) Bruch's membrane or anterior sclera should be used as a reference plane when measuring laminar depth. Prospective observational study. One hundred fifty-five glaucoma patients and 35 healthy controls. Anterior laminar depth from a Bruch's membrane (LD-BM) or anterior sclera (LD-AS) reference plane were measured with optical coherence tomography. Two neuroretinal parameters, minimum rim width and retinal nerve fiber layer thickness, in addition to peripapillary choroidal thickness were measured. Factors related to laminar depth were determined with mixed-effects modeling. Cutoffs for significant change in each parameter were estimated from variability in healthy controls over 1 year. The occurrences of significant change in laminar depth and neuroretinal parameters were compared with survival models. Because normal aging has a clear effect on neuroretinal parameters, but not on laminar depth, changes in neuroretinal parameters were adjusted for age-related reduction. Longitudinal changes in laminar depth and neuroretinal parameters. Glaucoma patients were followed up for a mean of 3.90 years (range, 2.03-5.44 years). The LD-BM was influenced significantly more by choroidal thickness (1.14 μm/μm; 95% confidence interval, 1.07-1.21) than was the LD-AS (0.15 μm/μm; 95% confidence interval, 0.08-0.22). Posterior movement of the lamina (LD-BM increase or LD-AS increase) occurred with the same frequencies as thinning in neuroretinal parameters. Anterior movement of the lamina was detected more frequently with the Bruch's membrane (LD-BM decrease) compared with the anterior sclera (LD-AS decrease) reference plane (hazard ratio, 3.23; P < 0.01). Significant choroidal thinning occurred in most patients (25/28 [89%]) in whom anterior movement of the lamina occurred with the Bruch's membrane, but not the anterior sclera, reference plane (LD-BM decrease without LD-AS decrease). Patients had a wide range of individual rates of change of choroidal thickness, from -20.00 to 17.09 μm/year (mean, -1.62 μm/year). Lamina cribrosa depth should be measured from an anterior sclera reference plane to reduce the influence of choroidal thickness changes. In glaucoma patients, lamina cribrosa depth changes are detected with similar frequency as neuroretinal parameter changes. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 May 2017.
All research outputs
#14,787,133
of 25,382,440 outputs
Outputs from Ophthalmology
#4,794
of 6,764 outputs
Outputs of similar age
#162,825
of 324,469 outputs
Outputs of similar age from Ophthalmology
#66
of 116 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,764 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.7. This one is in the 28th percentile – i.e., 28% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 324,469 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 116 others from the same source and published within six weeks on either side of this one. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
