Angulation of the inner nuclear layer as an indicator of the severity of macular pseudohole.

Purpose: To investigate foveal morphologic parameters related to visual acuity and the stages classified in this study reflect the severity of the macular pseudohole (MPH).

Methods: Seventy-eight eyes of 78 consecutive patients diagnosed with MPH were studied. Quantitative optical coherence tomography (OCT) parameters including central foveal thickness, parafoveal thickness, parafoveal inner and outer retinal thickness (PIRT and PORT), pseudohole depth, pseudohole diameter, and inner nuclear layer (INL) angulation were measured and the morphologic features of the inner retina (disorganization of retinal inner layers (DRIL)) and the photoreceptor layer (external limiting membrane (ELM), ellipsoid zone (EZ), interdigitation zone (IZ), and cotton ball sign) were determined.

RESIDUAL VITREOUS CORTEX AT THE FOVEA DURING VITRECTOMY FOR PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

Purpose: To investigate the frequency of residual cortex and the effectiveness of removal of residual cortex in the fovea during vitrectomy for primary rhegmatogenous retinal detachment repair.

Methods: We retrospectively reviewed the charts and the operative videos of the 80 patients (80 eyes) who underwent vitrectomy for repair and who were observed for more than 6 months. After triamcinolone acetonide injection, we observed residual cortex on the surface of the retina.

Hyperreflective foveal lesion observed with optical coherence tomography in cases of epiretinal membranes with a firm foveal attachment.

Purpose: To report the optical coherence tomography (OCT) findings of the firmly attached foveal area and to investigate the functional results and predictive values in correlation to the degree of firmness of the foveal adherence of the epiretinal membrane (ERM).

Methods: We retrospectively reviewed the medical records regarding 167 eyes of 166 patients who underwent vitrectomy for the removal of the ERM between January 2009 and December 2012. We evaluated the degree of foveal attachment in all the patients based on the surgical video and reviewed the OCT images.

Morphologic and functional association of retinal layers beneath the epiretinal membrane with spectral-domain optical coherence tomography in eyes without photoreceptor abnormality.

Purpose: To access the differential thickening of retinal layers in the epiretinal membrane (ERM) and to determine their correlation with visual acuity.

Methods: Prospective and comparative case series of 22 patients, each of whom has one unilateral ERM eye and one normal eye. The eyes with abnormal photoreceptor layer by OCT images were excluded.
