Abstract Details

Purpose:

To conduct a study on the evaluation of juxtapapillary choroidal thickness of patients suspected with glaucoma obtained thru SD-OCT and its correlation with perimetry results

Setting:

University of Santo Tomas Hospital, Sampaloc, Manila, Philippines

Methods:

74 eyes diagnosed as “glaucoma suspect” had standard automated perimetry (SAP) to document functional glaucomatous damage using optimal near-point correction using the Humphrey Visual Field Analyzer II, 30-2 or 24-2 SITA-standard program (Carl Zeiss Meditec, Inc., Dublin, CA). SD-OCT imaging (Cirrus HD-OCT, Carl Zeiss Meditec, Inc., Dublin, CA) of the RNFL was also done to look for structural glaucomatous damage and in using Enhanced Depth Imaging of the optic nerve and the Cirrus caliper tool, choroidal thickness was measured. The population was classified in 2 groups: those with structural or functional glaucomatous damage (Group 1) and those without (Group 2).

Results:

One-Way Multivariate Analysis of Covariance (MANCOVA) was used in comparing the mean temporal and nasal choroidal thickness scores. In comparison of the Mean Temporal Choroidal Thickness, there is no statistical difference between patients with and without Glaucomatous Damage, with an F=1.83 and a p=0.1801. Similar results are seen in the Mean Nasal Choroidal Thickness which had an F=1.82 and p=0.1821. The mean temporal and nasal choroidal thickness scores of the two groups at different juxtapapillary locations: 0μm, 250μm, 500μm, 750μm and 1000μm away from the disc were not statistically different.

Conclusions:

Juxtapapillary choroidal thickness is not correlated with structural and functional glaucomatous damage and cannot be considered a variable in glaucoma management.
