Blindness caused by severe vasculitis or uveitis is rare in juvenile systemic lupus erythematosus (JSLE) patients. In a 27-year period, 5367 patients were followed at our Paediatric Rheumatology Division and 263 (4.9%) patients had JSLE (American College of Rheumatology criteria). Of note, two (0.8%) of them had irreversible blindness. One of them presented with cutaneous vasculitis and malar rash, associated with pain and redness in both eyes, impairment of visual acuity due to iridocyclitis and severe retinal vasculitis with haemorrhage. Another patient had peripheral polyneuropathy of the four limbs and received immunosuppressive drugs. Three weeks later, she developed diffuse herpes zoster associated with acute blindness due to bilateral retinal necrotizing vasculitis compatible with varicella zoster virus ocular infection. Despite prompt treatment, both patients suffered rapid irreversible blindness. In conclusion, irreversible blindness due to retinal vasculitis and/or uveitis is a rare and severe lupus manifestation, particularly associated with disease activity and viral infection.

Thyroid-associated ophthalmopathy (TAO), an autoimmune disease closely related to thyroid dysfunction, remains a challenging ophthalmic condition among adults. Its clinical manifestations are complex and diverse, and disease progression can lead to exophthalmos, diplopia, exposure keratitis, corneal ulceration, and compressive optic neuropathy, resulting in irreversible vision damage or even blindness. Traditional treatment methods for TAO, including glucocorticoids, immunosuppressants, and radiation therapy, often have limitations and side effects, making this disease problematic in ophthalmology.

Background: Glaucoma, particularly open-angle glaucoma (OAG), is a leading cause of irreversible blindness, associated with optic nerve damage, retinal ganglion cell death, and visual field defects. Corneal biomechanical properties and cellular components, such as corneal nerve and keratocyte densities assessed by in vivo confocal microscopy (IVCM), may serve as biomarkers for glaucoma progression. This study aimed to explore the relationship between corneal nerve parameters, keratocyte density, and optical coherence tomography (OCT)-derived retinal nerve fiber layer (RNFL) thickness in primary open-angle glaucoma (POAG) patients and controls.

Early detection is crucial for preventing irreversible damage. The pupillary light reflex (PLR) has proven useful in glaucoma diagnosis, and mobile technologies like the AI-based smartphone pupillometer (AI Pupillometer) offer a promising solution for accessible screening.

Introduction: Uveitis, a severe inflammatory disease affecting the uvea, is associated with visual impairment and irreversible blindness. Asperulosidic Acid (ASPA), derived from , is known for its notable anti-inflammatory and antioxidant characteristics.
Methods: The present study explored the potential anti-inflammatory effects and the fundamental processes of ASPA by injecting it or a placebo into the vitreous of rats with endotoxin-induced uveitis (EIU).
