Lens-Induced Glaucoma
Excerpt
Lens-induced glaucoma (LIG) was originally described by Gifford in 1900 as glaucoma associated with hyper-mature senile cataracts (HMSC). Von Ruess independently described LIG as glaucoma with spontaneous absorption of lens matter through an intact capsule. The literature has described a multitude of similar entities over the decades. LIG is secondary glaucoma mimicking acute angle-closure glaucoma (ACG), with normal intraocular pressure (IOP) and open angles in the contralateral eye and prompt relief of symptoms following cataract extraction.
Based on the pathogenesis, LIG is further classified as:
1. Lens protein-related: Leakage of lens protein across an intact or a breached lens capsule. This form includes:
Phacolytic glaucoma (PLG)
Lens-particle-induced glaucoma (LPIG)
Phacoanaphylactic glaucoma (PAG)
2. Aqueous flow obstruction: Anatomical obstruction of aqueous flow from the posterior to the anterior chamber. This type includes:
Phacomorphic glaucoma (PMG)
Pupillary block glaucoma (PBG)
Some causes, like pseudo-exfoliation glaucoma and ciliary block glaucoma, are debatable entities under LIG.
