      Ultrastructural changes detected using swept-source optical coherence tomography in severe vitreopapillary traction: a case report

      Vitreopapillary traction is an uncommon condition characterized by strong adhesion and the traction of the posterior hyaloid onto the optic disc and peripapillary retina, leading to optic disc elevation and visual loss. An 85-year-old man presented with a 6-month history of slow, progressive visual loss in the left eye along with optic disc edema. Swept-source optical coherence tomography B-scans revealed circumpapillary anterior-posterior persistent traction of dense vitreous strands onto the optic disc. Visual field examination demonstrated mild, generalized, diffuse sensitivity loss and blind-spot enlargement. A 25-gauge posterior vitrectomy was performed with posterior hyaloid separation from the optic disc, resulting in ...

    2. The role of optical coherence tomography in Alzheimer’s disease

      The role of optical coherence tomography in Alzheimer’s disease

      Background Alzheimer’s disease (AD) is the most common cause of dementia and its incidence is increasing worldwide along with population aging. Previous clinical and histologic studies suggest that the neurodegenerative process, which affects the brain, may also affect the retina of AD patients. Main body Optical coherence tomography (OCT) is a non-invasive technology that acquires cross-sectional images of retinal structures allowing neural fundus integrity assessment. Several previous studies demonstrated that both peripapillary retinal nerve fiber layer and macular thickness measurements assessed by OCT were able to detect neuronal loss in AD. Moreover, recent advances in OCT technology, have allowed ...

    3. Macular Thickness Measurements with Frequency Domain-OCT for Quantification of Retinal Neural Loss and its Correlation with Cognitive Impairment in Alzheimerʼs Disease

      Macular Thickness Measurements with Frequency Domain-OCT for Quantification of Retinal Neural Loss and its Correlation with Cognitive Impairment in Alzheimerʼs Disease

      Purpose To evaluate the ability of frequency domain optical coherence tomography (fd-OCT) to estimate retinal neural loss in eyes with Alzheimer’s disease (AD). We also verified the existence of a correlation between AD-related cognitive impairment and macular and peripapillary retinal nerve fiber layer (RNFL) thickness measurements. Methods fd-OCT scans were obtained from 45 eyes of 24 patients with AD and 48 control eyes. Peripapillary RNFL, macular full-thickness and segmented inner macular thickness parameters were calculated. The inner macular parameters included macular retinal nerve fiber layer (mRNFL) thickness, ganglion cell layer (GCL) plus inner plexiform layer thickness (GCL+), and RNFL ...
