| Abstract |
Understanding the changes that occur in the choroid is of paramount importance in various uveitis entities. B-scan ultrasonography and indocyanine green angiography can be used to study choroid. Currently, spectral-domain optical coherence tomography is used as the standard noninvasive technique to study the choroid by enhanced depth imaging. Our aim was to study the structural visibility of the choroid using spectral-domain optical coherence tomography in the same area of interest in patients with uveitis with posterior segment manifestations using conventional, enhanced depth imaging (EDI), and combined depth imaging (CDI) techniques. Fifty-eight (58) eyes of 48 patients between age group 9 and 82 years were confirmed cases of uveitis. Out of the 48 patients, 21 (43.75%) were males while 27 (56.25%) were females. Sixteen eyes (27.59%) had intermediate uveitis, 33 (56.9%) had posterior uveitis, and 9 eyes (15.51%) had panuveitis. For posterior vitreous, there was substantial agreement for all the three groups (kappa value of 0.77, 0.73, and 0.72 in groups 1, 2, and 3, respectively). For vitreo retinal interface and inner choroid, there was perfect interobserver agreement, and for outer choroid, there was substantial to almost perfect interobserver agreement (kappa value of 0.71, 0.81, and 0.86 in groups 1, 2, and 3, respectively). Chi-squared test was done to compare the three groups. The method of scanning had a significant effect on the visualization of posterior vitreous and the outer choroid (p < 0.01) and did not have an effect on the visualization of vitreoretinal interface, inner retina, outer retina, and inner choroidal layers (p > 0.05). The CDI technique alone might provide a good structural visibility compared to normal and EDI scanning done separately in patients with uveitis with posterior segment pathology. CDI OCT technique is thus able to visualize all posterior structures in a single image in patients with uveitis with posterior segment manifestations. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 08 November 2015.
All research outputs
#17,776,579
of 22,832,057 outputs
Outputs from Journal of Ophthalmic Inflammation and Infection
#99
of 185 outputs
Outputs of similar age
#154,620
of 229,095 outputs
Outputs of similar age from Journal of Ophthalmic Inflammation and Infection
#3
of 5 outputs
Altmetric has tracked 22,832,057 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 185 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 38th percentile – i.e., 38% 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 229,095 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
