眼内铁异物可致眼球铁锈症及严重的眼内组织损伤已众所周知,但对眶内铁异物所致眼内变化所知甚少。一般认为,眶内异物对眼球无损害作用,因此勿需摘出。作者通过眶内近巩膜壁的铁异物其铁离子进入眼球的实验观察,对传统的观点提出异议,认为持续的长期的眶内铁离子可穿入眼内,并能导致铁锈症及眼内组织的损害而影响视力。所用材料为16只家兔,重2.5～3公斤。将12只家兔双眼颞下球结膜切开,暴露巩膜,将15mg
Intraocular iron foreign body can cause eye rust and severe intraocular tissue damage has been well known, but very little is known about intraocular changes caused by intraorbital iron foreign body. It is generally believed that intraorbital foreign bodies have no damaging effect on the eye and therefore need not be removed. The author through the orbital near the scleral wall of the iron foreign body into the eye of iron ions in the experimental observation of the traditional point of objections, that sustained long-term orbital iron ions can penetrate the eye and can lead to rust and intraocular tissue Damage and affect vision. The material used was 16 rabbits weighing 2.5 to 3 kg. Twelve rabbit eyes under the infratemporal conjunctiva incision, exposing the sclera, will be 15mg
