Static and Dynamic Measurement of Ocular Surface Temperature in Dry Eyes

Table 2

The ten OST indices studied.

OST indices	Description	Remarks
GCC	Geometric center of the cornea (midway between LT and LN)	Most commonly studied in the literature
MOST	Mean OST of the ROI	—
	Minimum temperature of ROI	Study of the minimum and maximum temperature of the ocular surface
	Maximum temperature of ROI
T1	Extreme temporal conjunctiva	Study of the different areas of the limbus and conjunctiva
T4	Extreme nasal conjunctiva
CT	Midtemporal conjunctiva (midway between T1 and LT)
LT	Temporal limbus
LN	Nasal limbus
CN	Midnasal conjunctiva (midway between T4 and LN)
