intraoculare

Intraocular, sometimes written intraoculare in some languages, is a medical term meaning located within the eyeball. In ophthalmology it is used to describe structures, fluids, conditions, or procedures that occur inside the eye.

The eye's interior includes the anterior and posterior chambers filled with aqueous humor, the vitreous body occupying the main cavity, and the optical tissues such as the lens, retina, and optic nerve.

Common uses include intraocular pressure, a key measurement in glaucoma; intraocular injections, such as intravitreal or intracameral injections, which deliver medicines directly into the eye; and intraocular lenses, implanted during cataract surgery.

Historical note: The modern use of intraocular lenses began with Sir Harold Ridley's 1949 development of the IOL, which enabled safer cataract extraction. Today, cataract surgery often employs phacoemulsification and micro-incisional techniques.

Risks and considerations: Intraocular procedures carry risks such as endophthalmitis, retinal detachment, vitreous hemorrhage, lens or corneal complications, and transient increases in intraocular pressure. Proper technique, sterile care, and postoperative monitoring reduce these risks.
