Lens-Particle Glaucoma Causes
Lens-particle glaucoma can develop when fragmented lens debris is retained inside the eye following surgery or injury/trauma. Without surgery or injury/trauma, lens-particle glaucoma cannot develop, and it is not associated with the natural lens becoming dislocated from its normal position. Some examples of how lens-particle glaucoma may occur following surgery or injury/trauma are as follows:
Lens debris retained inside the eye spontaneously fragments into small (sometimes invisible to an examining doctor) particles that eventually migrate into the anterior chamber. There, they obstruct the flow of fluid (aqueous humor) from the eye, resulting in increased IOP and a possible progression to glaucoma.
It should be noted that a variety of conditions may cause elevation of IOP following injury or surgery, and the specific diagnosis of lens-particle glaucoma is determined by an ophthalmologist by means of examination and testing (see below).
Lens-particle glaucoma is only one of a group of conditions called lens-related or lens-induced glaucoma. Other diseases in this group include glaucoma due to lens swelling, lens dislocation, pupillary block, and phacolytic glaucoma.
