A rare brain operation has preserved the vision of a patient with cat-eye-shaped pupil deformity, infohub.kz reports, citing Medical Xpress.
The man sought medical help after his vision deteriorated sharply and his pupils changed shape, becoming vertically elongated. Diagnostic tests revealed a rare pathological growth that was compressing the optic nerves and disrupting blood supply to the visual centers of the cerebral cortex. Without urgent surgery, the patient faced complete and irreversible blindness.
During a microsurgical procedure lasting several hours, neurosurgeons carefully relieved the compression on the optic tracts and restored normal fluid drainage. The difficulty of the operation lay in the proximity of vital brainstem structures, damage to which could have caused severe neurological complications.
The postoperative period passed without complications, and the function of the visual system recovered within a few weeks. The doctors noted that the successful outcome confirmed the importance of early detection of vascular and tissue abnormalities in the area of the optic chiasm. Such clinical cases give physicians valuable experience for treating severe pathologies of the visual system.
