• Suggestibility

  Morphological studies in tvrm5 mice demonstrated increased cell shedding and the presence of large multinucleated RPE cells, suggesting defects in intercellular adhesion and cytokinesis. [ncbi.nlm.nih.gov]

  Several mutations in separate genes have been linked to these disorders suggesting that this group is genetically as well as clinically heterogeneous. [disorders.eyes.arizona.edu]

  The findings suggest a role for CTNNA1 in macular degenerative diseases. CTNNA1 encodes the protein CTNNA1, an alpha-catenin, which is part of the cellular machinery that glues cells to one another. [jax.org]

  The mutation segregates with the disease phenotype (Z max 4, Θ 0) strongly suggesting that it causes the macular disease in this family. [nature.com]

Because of the bilateral subfoveal localization no laser treatment was advised. Usually, good visual acuity is maintained in this uncommon inherited macular disease. However, acute visual loss can be caused by the ingrowth of subretinal new vessels. [ncbi.nlm.nih.gov]

These entities typically occur in midlife and carry a good visual prognosis in at least one eye. [reviewofophthalmology.com]

This delineation is key because of the better visual prognosis associated with multifocal pattern dystrophy. A better prognosis is also found with multifocal pattern dystrophy when compared with basal laminar drusen. [reviewofoptometry.com]

The prognosis for pattern dystrophies is good, with patients maintaining reading-level vision in at least one eye throughout the remainder of their life. 3 This patient has not yet returned to the clinic. OM References available upon request. [optometricmanagement.com]
