Abstract:

Introduction and Purpose: Compare the values of coroid thickness in primary hypothyroidism and hyperthyroidism cases with healthy individuals. Methods and tools: This prospective-planned case-control study included 20 eyes of the hypothyroidic phenomenon, 20 eyes of the hyperthyroidic phenomenon, 20 eyes of the volunteer healthy individual.After the detailed ophthalmological examination of all participants, coroid thickness measurements were performed with the Spektralis Domain Optical Coherence Tomography (SDOKT) device. The subfoveal coroid thickness (SFKK), which was later manually measured, was measured by the values of the 1000 μm nasal and temporal coroid thickness (NKK) and temporal coroid thickness (TKK). It also noted the automatically measured central macula thickness (MMK) values. Results: While the central macula thickness and NKK values are similar in each 3 groups (p: 0,154 and p: 0,148), the SFKK and TKK values in the groups, respectively, 295,55±11,80 μm, 352,45±9,72 μm, 270,60±10,84 μm, 260,35±12,10 μm, and 254,71±8,02 μm, 251,00±7,36 μm in the control group, were statistically significant differences between the 3 groups (secondly; p: 0,020 and p<0,001). In hypothyroidic cases, the SFKK and TKK values were significantly higher according to the control group (respectively; p: 0,016 and p<0,001). Discussions and Results: Primary hypothyroid phenomena have been found that the coroid thickness is significantly thick according to the control group. These phenomena can be monitored by regular eye examinations in terms of paquicoroid spectrum diseases.
