J AAPOS
. 2016 May;
20(3):214-9.
PMID: 27164425
Purpose: To report the training/certification process of nonphysician imagers, image quality, and factors that affected image quality in the National Eye Institute sponsored multicentered e-ROP study. Methods: Nonphysician imagers underwent...

Ghodasra D, Thuangtong A, Karp K, Ying G, Mills M, Wilson C, et al.
J AAPOS
. 2012 Oct;
16(5):431-6.
PMID: 23084379
Purpose: To describe the rate of change in retinal vessel width and tortuosity in eyes that develop treatment-requiring, or type 1, retinopathy of prematurity (ROP) versus eyes that do not...

Kwon J, Ghodasra D, Karp K, Ying G, Wilson C, Huang J, et al.
J AAPOS
. 2012 Jul;
16(4):350-3.
PMID: 22824490
Background: The clinical response to retinopathy of prematurity (ROP) treatment is currently assessed subjectively. This study aims to quantify treatment response objectively by assessing changes in digital images of posterior...

Shah D, Wilson C, Ying G, Karp K, Cocker K, Ng J, et al.
Br J Ophthalmol
. 2011 Jan;
95(10):1442-5.
PMID: 21270432
Aims: To determine correlation of width and tortuosity between expert graders and computer-assisted image analysis of the retina in narrow-field images of eyes with retinopathy of prematurity. Methods: 11 digital...

Ghodasra D, Karp K, Ying G, Mills M, Wilson C, Fielder A, et al.
Arch Ophthalmol
. 2010 Jun;
128(6):719-23.
PMID: 20547949
Objective: To determine whether quantitative analysis of retinal vessel width and tortuosity from digital images discriminates which eyes with preplus retinopathy of prematurity (ROP) progress to treatment severity. Methods: Posterior...

Shah D, Karp K, Ying G, Mills M, Quinn G
J AAPOS
. 2009 Oct;
13(5):507-8.
PMID: 19840733
Identification of type 1 retinopathy of prematurity (ROP) relies heavily on the presence of characteristics of plus disease, especially tortuosity. However, a relatively infrequent subset of eyes with type 1...

Shah D, Wilson C, Ying G, Karp K, Fielder A, Ng J, et al.
J AAPOS
. 2009 Oct;
13(5):504-6.
PMID: 19840732
Plus disease is a major indicator for treatment in retinopathy of prematurity (ROP), and computer-assisted image analysis of vessel caliber and tortuosity in the posterior pole may indicate disease progression...

Am J Ophthalmol
. 2009 Mar;
147(6):1086-91, 1091.e1-2.
PMID: 19286152
Purpose: To assess whether the rate of change of retinal vessel diameter can help identify infants at the highest risk for severe retinopathy of prematurity (ROP). Design: Thirty-five infants at...
