PURPOSE Retinoblastoma is a rare eye cancer that generally occurs before 5 years of age and often results in enucleation (surgical removal) of the cancerous eye. In the present study, we sought to determine the consequences of early monocular enucleation on the morphological development of the anterior visual pathway including the optic chiasm and lateral geniculate nucleus. METHODS A group o...
Maintenance of ocular viability is one of the major impediments to successful whole-eye transplantation. This review provides a comprehensive understanding of the current literature to help guide future studies in order to overcome this hurdle. A systematic multistage review of published literature was performed. Three specific questions were addressed: (1) Is recovery of visual function follow...
1. We recorded extracellularly from 1045 neurones in area 17 of seven monocularly deprived kittens and we employed careful sampling techniques to examine the effects of removing the signals from the non-deprived eye on the proportion of cells responding to stimulation of the deprived eye.2. Monocular deprivation itself produced a pronounced over-all change in the ocular dominance of neurones in...
BACKGROUND Choroidal melanoma is the most common primary malignancy of the eye. Enucleation has been the mainstay of treatment, but new and more effective options have recently been proposed as eye- and vision-sparing alternatives. METHODS We reviewed the medical literature for trials and case reports involving the evolution, current uses, and limitations of alternatives to enucleation for tr...
Self-enucleation or oedipism is a term used to describe self-inflicted enucleation. It is a rare form of self-mutilation, found mainly in acutely psychotic patients. We propose the term incomplete oedipism to describe patients who deliberately and severely mutilate their eyes without proper enucleation. We report the case of a 32-year-old male patient with a five-year history of psychotic depre...
Panophthalmitis is the most extensive ocular involvement in endophthalmitis with inflammation in periocular tissues. Severe inflammation of the anterior and posterior segments is frequently accompanied by corneal opacity, scleral abscess, and perforation or rupture. Enucleation or evisceration was the only remaining viable treatment option when all options to salvage the eye had been exhausted....
