G6PD-Carenza e degenerazione maculare legata all'età
Full text linkPurpose: Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly in Western Countries. Evidence indicates that Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency may protect against ischemic disease and ocular vascular disorders. This study was undertaken to ascertain whether G6PD deficiency may protect against AMD.Materials and Methods: 79 men with late-stage AMD and 79 male, age-matched controls without AMD were recruited. Smoking status and clinical history were recorded. Complete blood count, hemoglobin, glucose, creatinine, cholesterol, triglycerides, transaminases, bilirubin, and erythrocyte G6PD activity were measured. Association between G6PD deficiency and AMD was investigated.Results: G6PD deficiency was found in 7 (8.9%) AMD patients and 8 (10.1%) controls, a not statistically significant difference. Stepwise logistic regression disclosed that AMD was significantly associated with increased diastolic blood pressure (OR=1.09, 95% CI=1.03-1.15, P=0.02) and LDL-cholesterol (OR=1.02, 95% CI=1.0001-1.03, P=0.049) and lower values of white blood cell (WBC) count (OR=0.71, 95% CI=0.56-0.88, P=0.02) and aspartate aminotransferase (AST)
(OR=0.92, 95% CI=0.85-0.99, P=0.044).Conclusion: G6PD deficiency has no protective effect on nor is a risk factor for AMD. Larger studies are necessary to confirm whether increased diastolic blood pressure and LDL-cholesterol and lower values of WBC count and AST are risk factors for AMD
Anterior Acute Uveitis Report in a SARS-CoV-2 Patient Managed with Adjunctive Topical Antiseptic Prophylaxis Preventing 2019-nCoV Spread Through the Ocular Surface Route
No full textPurpose: To report the clinical-epidemiological association between acute anterior uveitis and acute bilateral follicular conjunctivitis in a 30-year-old female patient who had tested positive for the SARS-CoV-2 RT-PCR.Methods: A 30-year-old female visited emergency ophthalmology care at the Siena Crosslinking Centre, Italy, for a bilateral eye redness lasting two weeks, associated with unilateral photophobia and blurred vision in her right eye. She visited on the 23rd of March 2020 in the full pandemic period and presented chills and fever with a temperature of 39.0 degrees C, associated with complete loss of taste. Since eye examination findings, systemic symptoms and epidemiological criteria correlated with SARS-CoV-2 infection, she was referred to Siena University Hospital, Italy, for the SARS-CoV-2 nasopharyngeal buffer and haematological examinations for uveitis.Results: Eye examination revealed bilateral conjunctival hyperaemia with acute follicular conjunctivitis associated with right eye acute anterior uveitis characterized by diffuse pigmentary and whitish immune precipitates over the anterior capsule of the crystalline lens and initial anterior lens opacity explaining the blurred vision. Adjunctive prophylactic eye topical treatment, included in the acronym SHYPIO (0.02% sodium hypochlorite solution, 0.6% povidone iodine eye-drops and 10.50% ozonized oil eye-drops), was associated with conventional uveitis therapy to prevent the virus spread through the ocular surface route.Conclusion: Our report demonstrates that complicated acute anterior uveitis (iridocyclitis) with blurred vision could be associated with SARS-CoV-2 infection, being potentially sight-threatening for early complicated lens opacity. Ophthalmologists examining suspected or asymptomatic patients should be aware of the risk of 2019-nCoV infection
Management of macular oedema in diabetic patients undergoing cataract surgery
No full textPURPOSE OF REVIEW: The aim of this study was to describe all the treatment modalities used to prevent and manage macular oedema in diabetic patients undergoing cataract surgery. RECENT FINDINGS: Topical NSAIDs have been proposed to be an effective strategy to prevent postsurgical macular oedema (PME) in diabetic patients. The prophylactic use of intravitreal antivascular endothelial growth factors (anti-VEGF) drugs and steroids in these patients, even if effective, brings some concerns with regard to possible side effects. By contrast, in patients with a diagnosis of diabetic macular oedema (DME) at the time of cataract surgery, intravitreal therapy, both with anti-VEGF drugs and steroids, appears to be the best approach in order to control PME and achieve a good visual outcome. CONCLUSION: All diabetic patients undergoing cataract surgery should be treated with topical NSAIDs to prevent PME. Intravitreal anti-VEGF drugs and steroids, combined with cataract surgery, should be reserved for patients with preexisting DME
