Diabetic retinopathy as the leading cause of blindness and early predictor of cascading complications —risks and mitigation
AbstractProliferative diabetic retinopathy (PDR) the sequel of diabetic retinopathy (DR), a frequent complication of diabetes mellitus (DM), is the leading cause of blindness in the working-age population. The current screening process for the DR risk is not sufficiently effective such that often the disease is undetected until irreversible damage occurs. Diabetes-associated small vessel disease and neuroretinal changes create a vicious cycle resulting in the conversion of DR into PDR with characteristic ocular attributes including excessive mitochondrial and retinal cell damage, chronic inflammation, neovascularisation, a...

What Causes Sudden Vision Loss?
Discussion Vision loss, whether chronic or acute, is distressing at any time for patients and families. Prompt evaluation and treatment are important as maintenance of any acuity and light or movement is considered paramount. Most vision loss is due to chronic problems and aging issues but the differential diagnosis is broad. For any age, but especially children, uncorrected refractive errors can cause problems in not only in childhood but throughout someone’s lifetime. Visual impairment for distance vision is considered mild if worse than 6/12 in meters = 20/40 in feet or 0.3 LogMAR and for moderate impairment is 6/...

Central Retinal Artery Occlusion: Current Practice, Awareness and Prehospital Delays in Switzerland
ConclusionsCRAO awareness of the general population and physician awareness about the treatment options as well as the non-standardized prehospital organization, seems to be the main reason for the prehospital delays and impedes treating CRAO patients. Educational efforts should be undertaken to improve awareness about CRAO.

Detection and Grading of Hypertensive Retinopathy Using Vessels Tortuosity and Arteriovenous Ratio
AbstractHypertensive retinopathy (HR) refers to changes in the morphological diameter of the retinal vessels due to persistent high blood pressure. Early detection of such changes helps in preventing blindness or even death due to stroke. These changes can be quantified by computing the arteriovenous ratio and the tortuosity severity in the retinal vasculature. This paper presents a decision support system for detecting and grading HR using morphometric analysis of retinal vasculature, particularly measuring the arteriovenous ratio (AVR) and retinal vessel tortuosity. In the first step, the retinal blood vessels are segmen...

Association of acute retinal necrosis with ischemic stroke
We report the case of a 65-year-old male patient with symptoms of acute retinal necrosis at the Department of Ophthalmology, Semmelweis University. The clinical picture fulfilled the diagnostic criteria of the American Academy of Ophthalmology (AAO) and after 3 days of the immediately initiated adequate therapy, contralateral hemiparesis appeared, that was confirmed as an ipsilateral stroke by imaging study. The PCR analysis of an intraocular sample confirmed the presence of VZV. Mild anti-VZV IgA positivity was observed in the cerebrospinal fluid sample. Based on the current ophthalmic disease, the associated stroke along...

Threatening Blindness in a Child With Typical Hemolytic Uremic Syndrome
Hemolytic uremic syndrome (HUS) is the most common cause of acute kidney failure in children younger than five years. Central nervous system involvement occurs in 15% of patients, with clinical manifestations including confusion, coma, seizures, stroke, and cortical blindness. Ocular involvement in children with HUS is rare, but retinal and choroidal hemorrhages as well as ischemic retinopathy due to thrombotic microangiopathic lesions have been documented.

The Spectrum of Maculopathy in Mitochondrial DNA A3243G Mutation: A Case Series of Six Patients
CONCLUSIONS: A single mtDNA point mutation at locus 3243 can result in a variety of clinical presentations (MELAS, MIDD, or CPEO). Ocular involvement may manifest as a perimacular/peripapillary RPE atrophy/deposit, which can variably impact central visual function (from asymptomatic to legal blindness). The discovery of such a maculopathy should prompt the ophthalmologist to complete the personal and family history, namely, asking for the presence of diabetes mellitus and/or deafness.PMID:33930928 | DOI:10.1055/a-1386-5826
