Abstract Details


To evaluate choroidal thickness measurements in patients with dry age-related macular degeneration (AMD).


A prospective case series.


The choroidal thickness measurements were performed in 54 eyes of 30 cases with dry AMD in retina division of our ophthalmology department. Enhanced depth imaging (EDI) mode of spectral domain optic cohorence tomography (SD-OCT) was used for choroidal thickness measurements (Heidelberg Engineering, Heidelberg, Germany). Choroidal thickness was measured from the posterior edge of the retinal pigment epithelium to the choroid-sclera junction. The measurement values obtanied from the dry AMD cases were compared with 40 eyes of 20 age-matched healthy controls.


The mean ages were 70.4±4.1 years in dry AMD patients and 68.2±5.5 years in control group. The mean visual acuity values were 0.26±0.29 logMar in dry AMD group and 0.03±0.05 logMar in control group. The visual acuity values in the dry AMD group were found to be statistically lower than control group (p<0.05). The mean choroidal thickness measurements were 214.28±86.88 microns in AMD group and 326.23±45.98 microns in control group. The choroid was significantly thinner in the AMD group than the control group (p<0.05). A positive correlation was observed between visual acuity values and choroidal thickness in AMD group.


In dry AMD patients, the choroid was thinner than healthy controls. This finding may be the result of the progression of the disease.
