Introduction: Alzheimer’s disease (AD) is the commonest form of dementia worldwide. The modalities to diagnose AD are generally expensive and limited. Both CNS and Retina are derived from cranial neural crest, so the changes in retinal layers may reflect the changes in CNS tissue. Optical Coherence Tomography (OCT) machine can show the delicate retinal layers and is widely used in retinal disorders. The purpose of this study is to find a new biomarker to help clinicians diagnose AD by the means of retinal OCT examination. Methods: After considering the inclusion and exclusion criteria, 25 patients with mild and moderate AD and 25 normal matched subjects were enrolled in the study. OCT was done for all eyes. Central Macular thickness (CMT) and Ganglion Cell Complex (GCC) thickness were calculated. Groups were compared using SPSS 22 software. Results: Both GCC thickness and CMT were significantly decreased in patients with AD, compared to healthy age and sex matched subjects. Conclusion: Retinal changes, specifically CMT and GCC thickness, may reflect the AD process in brain. OCT may be considered as a non-invasive and inexpensive means to help diagnose the AD.

Aim. To assess the retinal and choroidal thickness and ganglion cell complex (GCC) in pubescent children with type 1 diabetes (T1D) without diabetic retinopathy (DR), using spectral domain optical coherence tomography (SD-OCT). Materials and Method. Sixty-four right eyes of 64 subjects with T1D and 45 right eyes of 45 age-matched healthy volunteers (control group) were enrolled in this study. The mean age of the subjects and controls was 15.3 (±SD = 2.2) and 14.6 (±SD = 1.5), respectively. SD-OCT was performed using RTVue XR Avanti. Ganglion cell complex (GCC), GCC focal loss volume (FLV), GCC global loss volume (GLV), choroidal thickness (CT), foveal (FT) and parafoveal thickness (PFT), and foveal (FV) and parafoveal volume (PFV) data were analyzed. Results. There was no significant difference between subjects and controls in the CT in the fovea and nasal, temporal, superior, and inferior quadrants of the macula. There were no significant correlations between CT, duration of diabetes, and HbA1C level (p=0.272 and p=0.197, resp.). GCC thickness did not differ significantly between the groups (p=0.448), but there was a significant difference in FLV (p=0.037). Significant differences between the groups were found in the PFT and PFV (p=0.004 and p=0.005, resp.). There was a significant negative correlation between PFT, PFV, and HbA1C level (p=0.002 and p=0.001, resp.). Conclusions. Choroidal thickness remains unchanged in children with T1D. Increased GCC FLV might suggest an early alteration in neuroretinal tissue. Parafoveal retinal thickness is decreased in pubescent T1D children and correlates with HbA1C level. OCT can be considered a part of noninvasive screening in children with T1D and a tool for early detection of retinal and choroidal abnormalities. Further OCT follow-up is needed to determine whether any of the discussed OCT measurements are predictive of future DR severity.

Abstract Background To evaluate choroidal thickness, ganglion cell complex and photoreceptor outer segment length in patients with breast cancer undergoing tamoxifen therapy using spectral domain optical coherence tomography (SD-OCT) and to compare the results to normal eyes. Methods Fourty four patients with breast cancer undergoing tamoxifen therapy and fourty one healthy controls were included in this prospective, comparative study. All participants underwent a complete ophthalmologic evaluation and SD-OCT. Subfoveal, nasal (nasal distance to fovea 500 μm, 1000 μm, 1500 μm) and temporal (temporal distance to fovea 500 μm, 1000 μm, 1500 μm) choroidal thickness measurements were performed using enhanced depth imaging mode of SD-OCT. Using an Early Treatment Diagnostic Retinopathy Study (ETDRS) circle at the macular level, the automated retinal segmentation software was applied to determine thicknesses of the ganglion cell complex (GCC) by adding the macular retinal nerve fiber layer, macular ganglion cell layer, and macular internal plexiform layer parameters. The photoreceptor outer segment (PROS) length was determined by manually as the distance from inner surface of ellipsoid zone to inner surface of retina pigment epithelium after automatic retinal segmentation. Results The mean choroidal thickness measurements were statistically greater in tamoxifen group than controls in all quadrants (p<0.001 for all quadrants). Of all tamoxifen users (44 eyes of 44 patients), 33 eyes (75%) had uncomplicated pachychoroid (UCP). Pachychoroid pigment epitheliopathy (PPE) was detected in 5 patients (11.3%) in tamoxifen group. Patients with PPE in one eye had UCP in the fellow eye. Central serous chorioretinopathy findings were observed in one patient. Tamoxifen users had statistically lower GCC thicknesses in all inner rings of ETDRS inlay and only in nasal outer ring (p:0.027, p:0.002, p:0.002, p:0.001 and p:0.030; respectively). No statistically significant difference was found between the groups in terms of mean subfoveal PROS length. Conclusions SD-OCT provides valuable information in identifying the structural changes and evaluation of ocular findings in patients receiving tamoxifen therapy. Increasing choroidal thickness, PPE, thinning GCC were detected in tamoxifen users. These OCT findings may be an early indicator of retinal toxicity for patients undergoing tamoxifen therapy in follow-up period.
