Feline glaucoma is best categorized as either secondary, congenital and anterior segment dysgenesis associated, or primary. More than 90% of all feline glaucoma develops secondary to uveitis or intraocular neoplasia. The uveitis is usually idiopathic and assumed to be immune-mediated, whereas lymphosarcoma and diffuse iridal melanoma account for many of the intraocular neoplastic-induced glaucoma in cats. Several topical and systemic therapies are useful in the control of the inflammation and elevated intraocular pressures associated with feline glaucoma. Enucleation remains the recommended therapy for blind glaucomatous feline eyes. Enucleated globes from cats with chronic glaucoma should be submitted to an appropriate laboratory for histologic confirmation of the type of glaucoma.

Diffuse iris melanoma leading to secondary glaucoma in a lion (Panthera leo)-A case report.
Vet Ophthalmol
December 2024
Departamento de Medicina Veterinária, Universidade Federal do Paraná (UFPR), Curitiba, Brazil.
Article Synopsis
- - A 12-year-old male African lion was diagnosed with eye issues, including discharge and swelling, leading to the discovery of an intraocular mass via ocular ultrasonography.
- - The lion underwent enucleation (removal of the eye), and histopathological analysis confirmed the presence of diffuse iris melanoma, a type of cancer affecting the iris and ciliary body.
- - While diffuse iris melanoma is common in domestic cats, it's rarely seen in larger felids like lions, and more research is needed to understand its impact and prognosis in these animals.
Effects of 0.024% latanoprostene bunod on intraocular pressure and pupil diameter in normal cats and cats with congenital glaucoma.

Department of Surgical Sciences, School of Veterinary Medicine, University of Wisconsin - Madison, Madison, Wisconsin, USA.
Objective: To evaluate the effects of latanoprostene bunod on intraocular pressure (IOP) and pupil diameter (PD) in normal cats and cats with feline congenital glaucoma (FCG).
Animals Studied: Five normal and 5 FCG cats.
Procedures: This masked, controlled crossover study comprised a 1-day Pre-treatment phase followed by two 10-day Treatment phases, each followed by a 10-day Recovery phase.

Effective strategies for the neuroprotection and preservation of retinal ganglion cells (RGCs) remain elusive in the management of glaucoma. A spontaneous genetic model of glaucoma has been identified in cats and extensively characterized as a viable translational model, with eye size and anatomy similar to humans. In this study we sought to establish initial proof of concept for gene delivery to feline RGCs via intravitreal injection of AAV2 in normal cats.

Glaucoma is a neurodegenerative disease characterized by progressive optic nerve degeneration and retinal ganglion cell (RGC) loss. In early glaucoma, before obvious axon loss, highly organized pathological processes in RGCs occur sequentially, involving axons, dendrites and synaptic terminals. The optic nerve head (ONH) is the critical structure of early glaucomatous neurodegeneration.

Purpose: To characterize early trabecular meshwork (TM) morphologic abnormalities in a feline model of human primary congenital glaucoma (PCG) caused by mutation in LTBP2.
Methods: Eyes from 41 cats, including 19 normal and 22 homozygous for LTBP2 mutation, across various postnatal stages (birth, 2 weeks, 5 weeks, and 12 weeks) were paraformaldehyde fixed, anterior segments dissected, post-fixed in glutaraldehyde, osmicated, and processed and sectioned for transmission electron microscopy. Cell morphology, nuclear shape, and intertrabecular space (ITS) were quantitatively assessed, and the structure of the fibrillar extracellular matrix in the TM was systematically evaluated.
