Neurological and neuro-ophthalmological manifestations of snake bite: a systematic review.

Objective: Snakebites, a major health concern in developing countries, affect rural farming communities. Venom, primarily neurotoxin, injected during a snake bite disrupts the nervous system, causing symptoms like muscle weakness, paralysis, altered sensation, and coordination issues. This review focuses on evaluating neurological and neuro-ophthalmological manifestations associated with snakebites. Methods: A database search was conducted in EMBASE and PubMed for studies published from 2000 to 2023. The investigation centered on examining neurological and neuro-ophthalmological symptoms and signs, treatment approaches, treatment outcomes, and long-term complications of snake bites. Results: Neurological and neuro-ophthalmological symptoms were common in both neurotoxic and hemotoxic snake bites, especially in neurotoxic cases. Ptosis was a prevalent manifestation across various snake bites, along with respiratory paralysis, limb weakness, dysphasia, and visual disturbances in some instances. However, most patients improved without residual neurological symptoms after treatment. Conclusions: Understanding patterns of neurological manifestations contributes valuable insights for the comprehensive management of snakebite.

Scleritis as the harbinger of Granulomatosis with polyangiitis.

Introduction: Ocular and orbital involvement in Granulomatosis with polyangiitis (GPA) is common. GPA can lead to life and sight threatening complications due to necrosis and tissue melting. Cases: We report four cases presenting with ocular pain and redness for varied durations. One had diminution of vision. All of them had deep sectoral/diffuse congestion with one having scleral thinning. All were diagnosed with anterior necrotizing/non-necrotizing scleritis. One had associated penetrating ulcerative keratitis. Topical steroids and systemic non-steroidal anti-inflammatory drugs were started in all cases and rheumatology consultation was taken. Pertinent investigations were sent, and GPA was diagnosed. Intravenous immunosuppressive regimens and oral steroid were started and significant improvements were seen, preventing untoward complications. Conclusion: Scleritis could be manifesting feature of GPA so cautious history taking and evaluation is important. Management often requires multidisciplinary care and ocular features could be the reference guidelines to adjust dose of systemic medications of GPA.
