Inflammation & Infection

Ocular involvement in IBD is a rare extraintestinal manifestation, but may be critical because of its potential sight-threatening complications if not treated promptly and accurately, according to researchers.

Corneal cross-linking (CXL) is improving all the time, although all protocols retain the basic requirements for oxygen, riboflavin and UV light. Recent developments mean that CXL at the slit lamp is feasible, which will improve access to the procedure.

Biologic treatments can be utilised to help the eye heal itself in inflammatory conditions such as dry eye disorder.

In a paper, investigators identified strategies used by patients to reduce the cost of therapy and its impact on adherence to treatment. Patients may be reluctant to disclose challenges regarding adherence to dry eye disease therapy, as well as fears of worsening quality of life.

Patients are at risk for developing severe dry eye and ocular surface disease.

TP-03 met the primary and all secondary endpoints, effectively resolved Demodex blepharitis and was well-tolerated with no serious treatment-related adverse events. 56% of patients on TP-03 achieved the primary endpoint of complete collarette cure.

Investigators from the Karolinska Institutet and St. Erik Eye Hospital, Stockholm, Sweden, reported that they have developed a prognostic test, referred to as serUM, that they believe is a strong predictor of metastasis of uveal melanoma.

During a presentation at the Association for Research in Vision and Ophthalmology’s 2022 annual meeting, Dr Yuichi Hori and colleagues found that taping the top border of a surgical mask to a clinicians’ skin reduces the potential for ocular surface damage resulting from expirations of air reaching the ocular surface during the COVID-19 pandemic.

Authors of a retrospective study into complications associated with iris implants advise that the procedure should be considered as malpractice.

An end-of-week review of what happened in ophthalmology from April 9-April 15.

A team of investigators from Pohang University of Science and Technology has found that conjunctival goblet cell examination is important for the precise diagnosis and effective treatment of ocular surface diseases; however, CGC examination has not been possible until now due to lack of non-invasive devices.

A large retrospective analysis was carried out to investigate various risk factors for endophthalmitis as well as the effect of using a hydrogel sealant.

Successful outcomes in rhino-orbital-cerebral mucormycosis depend on awareness of red flag symptoms and signs, prompt diagnosis and early treatment with amphotericin B and surgery as necessary.

The investigators believe that, based on their findings, the impact of COVID-19 on the autonomous nervous system warrants further prospective studies and assessment of pupillary function might be a useful test for determining autonomic dysfunction.
