Purpose: To investigate the structural and functional changes of the retina and optic nerve in amblyopia. Methods: Eighteen patients with unilateral anisometropic amblyopia and 27 age-matched healthy controls were involved in this study. All patients underwent optical coherence tomography angiography (OCTA), pattern visual evoked potential (pVEP), and flash electroretinogram (fERG). Results: There was no statistically significant difference in terms of the fovea] avascular zone (FAZ), perifoveal superficial density, whole superficial density, parafoveal deep density, perifoveal deep density among the eyes (P > 0 0.05). Significant differences were found only in superficial capillary plexus (SCP) vessel density in whole (P = 0.029) and parafoveal (P = 0.008) image. In electrophysiological tests, while VEP latencies of the amblyopic eyes increased compared to nonamblyopic eyes and controls (P = 0.027), VEP amplitudes decreased in amblyopic and nonamblyopic eyes compared to controls (P = 0.01), amplitudes of the rod (P = 0.027) and cones (P < 0.001) also decreased in amblyopic eyes compared to nonamblyopic and healthy eyes. When we assessed the correlation between the parameters of OCTA and electrophysiological test, only a significant correlation was found between parafoveal SCP vessel density and VEP amplitudes (r = 0.341). Conclusion: We found a significant decrease only in SCP vessel density of the OCTA parameters in amblyopic eyes compared to healthy eyes. We detected a significant relationship between parafoveal SCP vessel density and VEP parameters, which might be associated with the underlying pathophysiology of the amblyopia.

Evaluation of retinal alterations in Parkinson disease and tremor diseases.

Optical coherence tomography (OCT) has been suggested as a method for detection of retinal alterations in neurodegenerative diseases. The usefulness of OCT as a diagnostic tool to differentiate Parkinson-s disease (PD) from other tremor diseases, remains unknown. We aimed to evaluate morphological changes of the retina in patients with PD, essential tremor (ET), essential tremor-Parkinson-s disease (ET-PD) using OCT. Forty-two eyes of 21 patients with PD, 24 eyes of 12 patients with ET, 24 eyes of 12 patients with ET-PD and 44 eyes of 22 age-matched healthy controls were included in the study. All participants underwent detailed neurological and ophthalmological examination. Measurements in all quadrants of macula and retinal nerve fiber layer (RNFL) thickness using OCT were recorded. There was no significant difference among the groups regarding age, sex. The average RNFL thickness was thinner in PD patients than that of ET (p = 0.032). The RNFL thickness in superior quadrant was lower in PD group compared with the ET and control group (p = 0.001, p = 0.016). Significant differences were observed in most of the macular thickness parameters excluding foveolar and foveal thickness (p = 0.865, 0.394). Correlations were found among several OCT parameters and disease duration or severity in all patient groups (p > 0.05). Retinal alterations were found in PD patients compared to ET. However, no significant retinal changes were detected by OCT in patients with ET and ET-PD compared to controls. According to our data, retinal assessments by OCT do not seem to be satisfactory for differentiation of these disorders.
