Purpose: We aimed to evaluate the normative pupillometry values and mean pupil dilatation speed in healthy individuals in different age groups in our study. Methods: The study group included 180 eyes of 90 healthy volunteers in different age groups. Group 1 consisted of 30 participants between the ages of 6 and 18, group 2 consisted of 30 participants aged 19–40, and group 3 consisted of 30 participants aged 41–75. Scotopic, mesopic, photopic, and dynamic measurements were taken with automatic pupillometry of Sirius Topographer (CSO, Firenze, Italy). The mean pupil dilation speed at the 18^th second was calculated according to dynamic measurements. Results: Group 1 had a significantly larger pupil diameter than groups 2 and 3 in all static and dynamic parameters, and the mean pupil dilation speed was the highest among the groups (P < 0.001 for all static and dynamic parameters). In addition, group 2 had a significantly larger pupil diameter than group 3 (P < 0.001 for all static and dynamic parameters) and the mean pupil dilation speed was faster than group 3 (P = 0.027). Conclusion: We have presented the static and dynamic parameters and the mean speed of pupil dilatation at the 18^th second with automatic pupillometry in healthy individuals in childhood, adulthood, and old age. More studies with higher participants and younger age children are needed.

X-linked juvenile retinoschisis (XLRS) is a disease considered characteristic for males. In this study we report a consanguineous family in which 3 daughters were diagnosed with XLRS. Typical signs of XLRS were detected in 2 girls, aged 4 and 15. Fundoscopic examination of the father and the oldest daughter (age 17) revealed bilateral atrophic macula and retinal thinning. Although rare and considered characteristic for males, XLRS can be seen in females in Middle-East countries that have a high rate of consanguineous marriage. It can be overlooked by ophthalmologists and these patients may be misdiagnosed.

The purpose of this study was to investigate the serum levels of malondialdehyde (MDA) which is a marker of oxidative stress, monocyte chemoattractant protein-1 (MCP-1) which has an important role in inflammation, and vitamin C which has antioxidant properties in patients with wet age-related macular degeneration (wAMD). Thirty patients with wAMD were included in the study and serum levels of MDA, MCP-1, and vitamin C were compared with healthy participants (n = 30). Serum vitamin C and MDA levels were measured using a spectrophotometric method. Serum MCP-1 levels were determined by the ELISA method. MCP-1 and MDA levels were higher in patients with wAMD compared with the control group (p < 0.05). Serum vitamin C levels were lower in patients with wAMD compared with the control group (p < 0.05). The increase in the MCP-1 levels in patients with wAMD may be associated with increased inflammation in wAMD. Decreased serum vitamin C and elevated MDA levels in patients with wAMD suggest increased oxidative stress in wAMD patients. These results indicate that the increased oxidative stress and inflammation can play a role in the pathogenesis of wAMD.

Objectives: To evaluate the effect of proptosis on choroidal thickness in patients with Graves' ophthalmopathy. Materials and Methods: Twenty-five eyes of 25 Graves' patients with proptosis, 25 eyes of 25 Graves' patients without proptosis, and 25 eyes of 25 healthy individuals were included in this prospective study. The subfoveal choroidal thickness and choroidal thicknesses at 6 points from the fovea at 500 mu m intervals were measured by Cirrus HD-OCT. All measurements were compared among the proptosis, non-proptosis, and control groups and the active, inactive, and control groups. Results: The mean subfoveal choroidal thickness in the proptosis group was 289.7 +/- 68.5 mu m, 322.5 +/- 55.8 mu m in the non-proptosis group, and 316.1 +/- 63.0 mu m in the control group. The mean nasal choroidal thickness was 260.5 +/- 63.5 mu m in the proptosis group, 293.9 +/- 57.9 mu m in the non-proptosis group, and 279.5 +/- 63.1 mu m in the control group. The mean temporal choroidal thickness was 261.8 +/- 60.9 mu m in the proptosis group, 289.0 +/- 51.8 mu m in the non-proptosis group, and 287.8 +/- 56.2 mu m in the control group. Mean choroidal thickness was 264.7 +/- 58.5 mu m in the proptosis group, 296.2 +/- 47.5 mu m in the non-proptosis group, and 288.3 +/- 55.1 mu m in the control group. There were no statistically significant differences among the groups with respect to choroidal thickness measurements (p>0.05). Conclusion: No significant difference in choroidal thickness was detected between Graves' patients with and without proptosis and the controls. There was no effect of clinical activation on choroidal thickness.

This study’s purpose is to determine the effects of current episode and the mood stabilizers on chorioretinal layer thicknesses of bipolar disorder (BD) patients using spectral-domain optical coherence tomography (SD-OCT). Sixty-seven patients were diagnosed with BD I and using lithium (Li) or valproic acid (VPA), of whom 20 were manic, 24 were depressive, and 23 were in remission, and 49 healthy individuals were included in the study. Peripapillary retinal nerve fiber layer (RNFL), ganglion cell layer, and macular thicknesses of the participants were measured automatically using SD-OCT, and their choroid layer thicknesses were measured manually using the depth imaging mode of SD-OCT. Statistical analysis of the data was performed using Statistical Package for the Social Sciences version 23.0. The patient group’s mean age was 39.78 ± 11.78, and the control group’s mean age was 42.06 ± 12.10. The mean disease duration was 13.22 ± 8.23 in the patient group, and 26 patients were using Li. While peripapillary RNFL thicknesses were lower in the patient group (P < .05), other layer measurements were similar between the groups. Moreover, the episodes experienced by BD patients did not affect chorioretinal SD-OCT measurements. The patients on VPA had significantly lower RNFL thicknesses compared to the control and the Li groups, and all chorioretinal measurements were similar between the Li and the control groups. As a result of the study, it was established that neurodegenerative processes play a role in the pathophysiology of BD and the usage of Li is protective against the neurodegeneration of RNFL. Retinal changes measured with SD-OCT can be used for the diagnosis and prognosis of BD and for evaluating responses to mood stabilizers.
