Ocular Manifestations, Visual Field Pattern, and Visual Field Test Performance in Traumatic Brain Injury and Stroke.

Purpose: To analyze ocular manifestations, visual field (VF) pattern, and VF test performance in traumatic brain injury (TBI) and stroke patients.

Methods: This retrospective, cross-sectional study included 118 patients (236 eyes) with TBI and stroke who had undergone VF testing by standard automated perimetry with the central 24-2 threshold test. Clinical features including best-corrected visual acuity (BCVA), intraocular pressure (IOP), ocular manifestations, and VF test results including VF defect pattern, reliability, and global indices were analyzed and compared between the TBI and stroke patients.

Spinocerebellar ataxia type 7 with -negative occult macular dystrophy as retinal manifestation.

: Spinocerebellar ataxia Type 7 (SCA7) is an autosomal dominant, progressive neurodegenerative disorder, primarily characterized by cerebellar ataxia. The disease is caused by the expansion of a CAG trinucleotide repeat within the gene when its CAG repeat sequences are extended beyond 38. The degree of retinopathy can vary from pigment change in the fovea to foveal atrophy and is correlated with the number of CAG repeats.
