macular pucker
Wrinkling or contracture of the macular retina, often occurring as a complication of intraocular tumor treatment.
Full Definition
Macular pucker, also known as epiretinal membrane, refers to the formation of fibrous tissue on the surface of the macula that causes retinal wrinkling and visual distortion. In ocular oncology, macular pucker can develop as a complication following various tumor treatments including brachytherapy, photocoagulation, or surgical interventions. The condition results from proliferation of glial cells and formation of contractile scar tissue on the internal limiting membrane. Patients typically experience metamorphopsia, reduced visual acuity, and central visual field defects. Treatment may require vitreoretinal surgery if visual symptoms are significant.
Usage
Usage note: Common post-treatment complication; affects central vision significantly.
