AI Article Synopsis
- The study aimed to establish a baseline rate of visual impairment (VI) due to diabetic retinopathy (DR) in Cambridgeshire, evaluating compliance with UK National Screening Committee (NSC) standards.
- A retrospective review of visual impairment certificates from 2004 and 2005 found 18 cases mainly due to DR, with calculated rates of 17.1 and 6.5 registrations per million per year for VI and severe VI, respectively.
- The registration rate for severe VI due to DR met national standards, while the overall VI registration rate was higher than that of 1990-1991 but within the range of 1999-2000 figures.
Article Abstract
Background/aims: The UK National Screening Committee (NSC) has set 18 standards for diabetic retinopathy (DR) screening services in England and Wales, the first of which is to reduce new visual impairment (VI) due to DR by 10% within 5 years. This study examined the incidence of VI due to DR in Cambridgeshire (City, South, and Huntingdonshire) in order to establish a baseline rate of VI registration.
Methods: A retrospective review of all certificates of visual impairment (CVI) for 2004 and 2005 was conducted. Hospital records of patients registered due to DR were reviewed to ascertain conformity to NSC Standards. The incidence of VI registration due to DR was calculated.
Results: The number of registrations predominantly due to DR was 18; 13 visually impaired and 5 with severe VI. The rates of VI and severe VI predominantly due to DR were 17.1 and 6.5 per million per year, respectively. The VI and severe VI registration rates in the diabetic population were 600 and 230 per million per year, respectively.
Conclusion: The severe VI registration rate due to DR lies within the national standard. The VI registration rate exceeds 1990-1991 national standards but lies within 1999-2000 national figures.

The eye is considered to be an immune-privileged region. However, several parts of the eye have distinct mechanisms for delivering immune cells to the injury sites or even in response to aging. Although these immune responses are intended to be protective, the visual acuity can be compromised by the release of pro-inflammatory cytokines by immune cells, which induce chronic inflammation and fibrosis.

Ocular surface chemical injuries often result in permanent visual impairment and necessitate complex, long-term treatments. Immediate and extensive irrigation serves as the first-line intervention, followed by various therapeutic protocols applied throughout different stages of the condition. To optimize outcomes, conventional regimens increasingly incorporate biological agents and surgical techniques.

Objectives: Fundoscopy is crucial in the emergency department to identify or rule out serious ocular and neurological conditions. Despite its clinical importance, fundoscopy is often omitted due to the technical challenges associated with traditional direct ophthalmoscopy, particularly for non-ophthalmologists. This study examines emergency physicians' practices, confidence levels, and training related to various modalities of fundoscopy including traditional direct ophthalmoscopes, binocular indirect ophthalmoscopes, panoptic ophthalmoscopes, slit lamp fundoscopy and fundus cameras; and explores the potential role of alternative modalities, such as fundus cameras, in Canadian emergency departments.

Altitude training has been widely adopted. This study aimed to establish a mice model to determine the time point for achieving the best endurance at the lowland. C57BL/6 and BALB/c male mice were used to establish a mice model of hypoxic training with normoxic training mice, hypoxic mice, and normoxic mice as controls.

Background: Idiopathic intracranial hypertension (IIH) is a condition where the pressure of the cerebrospinal fluid in the brain increases without a known cause. It typically affects adults but can also occur in adolescents and children, although it is less common. Numerous elements, including coagulopathy, have been documented in previous cases as potential etiological factors of IIH.
