The red eye

A Quality Improvement Project of Acute Red Eye Consultations in Primary Care: Improving the Identification of Red Flags

Aim The acute red eye or conjunctival injection is the most common ophthalmic presentation in primary care. The aim of this audit was to improve red eye consultations by increasing the number of red flag features documented in the history of patients. Method The National Institute of Clinical Excellence (NICE) Clinical Knowledge Summary (CKS) outlines red flag features, which should be documented for an acute red eye consultation. Two interventions were implemented to attempt to improve consultations. The first involved creating a template in the Egton Medical Information Systems. The second involved training doctors in the recognition of red flag features and identifying sight-threatening conditions. Red eye consultations and red flag features documented were recorded in the two months before and after the interventions. Results All documentation of red flag features assessed in this project increased post intervention. However, lateralisation, visual changes, and eye pain were commonly asked prior to the intervention and did not show a statistically significant difference. They showed an increase from 90% (19/21) to 100% (19/19), 71% (15/21) to 84% (16/19), and 67% (14/21) to 79% (15/19), respectively. After the interventions, significant increases in asking about headaches (14% (3/21) to 74% (14/19), pupil changes (5% (1/19) to 58% (11/19)), and method of injury (high velocity 10% (2/21) to 84% (16/19), foreign body 14% (3/21) to 84% (16/19), chemical 10% (2/21) to 84% (16/19) were observed (p<0.05). Photophobia inquiries also significantly increased (14% (3/19) to 79% (15/19), P<0.05). Conclusion  The number of red flag features identified and documented for acute red eye consultations increased with the introduction of an online template and a teaching session.

Pediatricians' knowledge, attitude and practice on treating children with red eye disease

BACKGROUND

Pediatricians play an important role in the early detection and prompt treatment of ocular disorders in children, including red eye disease. Our aim was to examine the knowledge level of pediatricians regarding treating children with red eye disease, as well as the factors that affect the knowledge level, and the potential implications of a low level of knowledge.

METHODS

In this correlational quantitative study, 152 expert pediatricians completed a questionnaire that included questions on knowledge, attitudes, and experience in treating red eye disease.

RESULTS

Respondents' mean level of knowledge was moderate. Most of the respondents (89.5%) knew that the most likely diagnosis for a child with red eyes and a discharge is viral conjunctivitis and that pain, blurred vision, and a clouded cornea, are symptoms indicative of a more complex systemic problem. In contrast, 78.3% of the pediatricians claimed that the treatment of choice for viral conjunctivitis is a conservative treatment that includes eye flushing and strict hygiene. However, 14.5% (n = 22) of the pediatricians were found to prescribe antibiotics. A negative association was found between the pediatrician's age and years of experience, and level of knowledge concerning treatment of children with red eye. A strong positive association was found between pediatricians' level of knowledge and their attitudes to performing eye tests. Moreover, a negative association was found between the level of knowledge and the number of cases in which pediatricians prescribed antibiotics for children with red eye.

CONCLUSIONS

The research findings indicate that lack of knowledge was more conspicuous among pediatricians with more experience. Knowledge appears to be critical both for readiness to treat red eye and for proper treatment. It is necessary to provide pediatricians with tools for treating eye disorders in children and to refresh their knowledge on red eye, particularly among pediatricians with more years of experience.

Nanotechnology-based formulations to amplify intraocular bioavailability

Conventional drug delivery formulations, such as eye drops and ointments, are mainly administered by topical instillation. The topical delivery of ophthalmic drugs is a challenging endeavor despite the eye is easily accessible. Unique and complex barriers, serving as protection against extrinsic harmful factors, hamper therapeutic intraocular drug concentrations. Bioavailability for deeper ocular tissues of the anterior segment of the eye is exceptionally low. As the bioavailability of the active substance is the major hurdle to overcome, dosing is increased, so the side effects do. Both provoke patient poor compliance, confining the desired therapeutic outcome. The incidence and severity of adverse reactions amplify evenly in the case of chronic treatments. Current research focuses on the development of innovative delivery strategies to address low ocular bioavailability and provide safe and convenient dosing schemes. The main objective of this review is to explore and present the latest developments in ocular drug delivery formulations for the treatment of the pathology of the anterior segment of the eye. Nanotechnology-based formulations, that is, organic nanoparticles (liposomes, niosomes/discosomes, dendrimers, nanoemulsions, nanosuspensions, nanoparticles/nanospheres) and inorganic nanoparticles, nanoparticle-laden therapeutic contact lenses, in situ gelling systems, and ocular inserts, are summarized and presented accordingly.
