Within the field of CMV research and telemedicine, the ability to create consistent, high-quality mosaics can be clinically useful.
This is a tremendous benefit when dealing with elderly patients, with asymmetric pupils or when the patient is taking certain medications. Accuracy softwsre reliability of telemedicine for diagnosis of cytomegalovirus retinitis.
Clinician versus reading center assessment of cytomegalovirus retinitis lesion size. Previous work has described normal optic disc appearance among different races. ChenNone; S. Constructing retinal fundus photomontages.
Each eye was photographed only once. The programs differed in their ability to create mosaics from the study eyes and also in toocon ability to incorporate all the individual photographs into the final mosaic.
Since each grader also determined the presence or absence of each feature of interest, we calculated the correlation coefficient for each eye—grader combination. Vessel breakage in the retinal montages had some of the lowest intra- and interrater reliability values and also displayed the weakest degree of correlation with a program's tlpcon.
Optic nerve head parameters of an indigenous population living within Central Australia.

In the first round of grading i. In this ancillary study, we included 89 eyes with a definite clinical diagnosis of CMV retinitis, 5 eyes with an uncertain diagnosis of CMV, and spftware eyes with a diagnosis from photographic review only.

For each grader, we obtained the rank for software programs 1, for 2, and 3 note that these dependent variables always sum to 6.
Although the i2k Retina and AutoMontage programs scored similarly in many aspects, all three graders ranked i2k Retina as the best program more frequently. Food and Drug Administration and state and local regulatory agencies.
Topcon TRC-NW6S Non-Mydriatic Retinal Camera
AusayakhunNone; S. Topcno patients presenting for their initial visit or diagnosed with CMV retinitis in the previous month were offered enrollment in the study.
There were several limitations to this study. Each of the photographic features documented by the three graders duplicated vessels, vessel breaks, misplaced images, relative blurriness, and overall quality was significantly lmagenet with a program being ranked as inferior, with vessel breaks having a weaker association than the other errors.
Keenan ; Todd P. They repeated this exercise on a set of 50 randomly selected duplicate mosaics approximately 2 weeks after the initial grading, to assess intrarater reliability.
