Table 2.

Distribution of skip areas based on circumferential location.

Clock Hour	Number of Skip Areas			Percent of Eyes with Skip Areas
Clock Hour	OS	OD	Overall	Percent of Eyes with Skip Areas
11 to 1	4	6	10	45%
1 to 3	0	1	1	5%
3 to 5	4	1	5	23%
5 to 7	4	5	9	41%
7 to 9	1	1	2	9%
9 to 11	2	1	3	14%

Indirect panretinal laser photocoagulation was initially performed by ophthalmologists-in-training in eyes with treatment-requiring ROP. Based on circumferential location, a significant difference in overall skip area distribution was found using Pearson's chi-square test (p=0.02).
