Background: Vaccination against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first approved on 8th of December 2020. Though safe and effective, very rare side effects continue to be identified as global vaccination advances. They do not necessarily leave "a signal" in public registries if incidence remains below previously reported total levels. Optic neuritis (ON) is a but recognised adverse event after immunisation. The risk post-vaccination ON visual outcome...

Purpose To evaluate changes in colour vision following intravitreal injection of Dexamethasone implant (Ozurdex) patients with diabetic macular oedema (DMO). Both red-green (RG) and yellow-blue (YB) chromatic sensitivity were assessed using the Colour Assessment & Diagnosis (CAD) test which isolates use signals provides age-corrected, statistical limits for normal trichromats. determine whether visual acuity (VA) post-treatment relate to central sub-field retinal thickness (CST). Methods...

To establish the level of confidence amongst UK ophthalmology specialist registrars (residents) in managing posterior capsule rupture (PCR) during cataract surgery.An online nine-item questionnaire was distributed to all registrars, recruited nationwide via regional representatives. Data collected included stage training, number completed operations, cumulative PCR rate, PCRs independently managed, understanding vitrectomy settings and fluidic parameters access simulation. Respondents...

Abstract Scale deposition has been a significant problem in the oil and gas industry. an adverse impact on production injection operations. The precipitation of scale near-wellbore area will diminish productivity wells loss injectivity water wells. This paper presents new non-corrosive agent to remove calcium carbonate, sulfate scales. Two sets coreflood experiments were conducted evaluate chemical anhydrite depositions. Coreflood by using remover stimulate dolomite cores with content 30 wt%...

Inherited retinal venous beading is a rare vascular disorder that characterised by tortuosity and of the veins. This can potentially lead to vision-threatening complications such as vitreous haemorrhage, macular hard exudation ischaemia. We report case sporadic unilateral in an 18-year-old white man who was referred his optician following routine eye examination. malformation did not involve any other ocular structure. He had no associated or systemic disorders. When last seen, he have...

Purpose Vascular and structural changes in the retina are used to grade progression diabetic retinopathy (DR) this is often taken as an indicator of severity vision loss. Changes visual function may, however, precede detectable damage. Red-green (RG) yellow-blue (YB) thresholds were measured patients with DR related their clinical grading classification. Methods 66 diagnosed diabetes examined. was graded according ETDRS scale no retinopathy, mild, moderate, severe presence/absence macular...
