Septic implantation syndrome

From Dog
Severe lens-induced uveitis with corneal edema, vascularization and hypopyon[1]

Septic implantation syndrome is an ophthalmic disease characterized by a slowly progressive or delayed-onset endophthalmitis with lens capsule rupture, lenticular abscess, and frequently intralenticular microorganisms.

In dogs, this is usually associated with traumatic penetration of the globe and lens capsule[2], such as a cat scratch wound or secondary to following phacoemulsification.

The trauma invariably leads to lenticular-induced uveitis.

There appears to be no apparent gender, age or breed predilections in dogs, except in cases of phacoemulsification, where the Labrador Retriever appears predisposed to developing this condition[3].

In most dogs, this leads to lens epithelial proliferation, pupillary occlusion and glaucoma, resulting in eye loss[4].
