Background: Equine ocular diseases pose a medical challenge due to long-lasting and cost-consuming therapies as well as economic issues associated with potential decrease in value of affected horses. The scale of the problem is significant but difficult to precisely define because epidemiological data is limited and lacks consistency in presentation. To date, no retrospective studies specifically investigating Arabian horses have been published.
Results: The aim of this cross-sectional study was to investigate the prevalence of ocular lesions and define the ocular diseases present in Arabian horses from breeding farms in Poland. Clinical and ophthalmic examination of 615 Arabian horses at Polish breeding farms (15% of Arabian population in Poland) were performed and medical history from the previous 5 years was analyzed. Data was obtained from review of veterinary archives and epidemiological interview of the resident veterinarian at each farm. The prevalence of ocular diseases was 9.75%. The following pathologies were diagnosed (with their respective prevalence): equine recurrent uveitis (ERU; 5.5%); cataract not related to ERU (3.3%); non-visual eyes (1.13%); posttraumatic lesions (0.8%); glaucoma (0.16%).
Conclusions: In this study, ERU was the most common ocular disease identified in Arabian horses in Poland. Its prevalence was lower than usually reported in Europe and the United States. There was no sex or farm predisposition but ocular disease prevalence increased with age. Other severe ocular pathologies were also observed, confirming that ocular diseases remain an important clinical problem.

Objective: Sierra Leone, a country where onchocerciasis is endemic in 14 of the 16 districts, was the focus of our investigation. Despite 17 rounds of annual ivermectin treatment since 2005, a report circulated by a local politician indicated an increase in cases of suspected onchocerciasis-related vision impairment in two villages (Mangobo and Petifu) in Tonkolili district. In response, the National Neglected Tropical Disease Program conducted a comprehensive investigation.

Herpes zoster Ophthalmicus (HZO) affecting the ophthalmic division (V1) of the trigeminal nerve. HZO may cause extraocular muscle palsies, with the third nerve being the most commonly affected and the fourth nerve the least. The combined involvement of the optic nerve and isolated paralysis of the eye muscle is very rare, with only limited case reports documenting this complication of ocular herpes zoster.

Introduction: Zellweger spectrum disorder (ZSD) refers to a group of autosomal recessive genetic disorders that affect multiple organ systems and are predominantly caused by pathogenic variants in PEX genes. ZSD present a wide clinical spectrum, ranging from the most severe form, Zellweger syndrome, to the mildest form, Heimler syndrome.

Ocular disorders encompass a broad spectrum of phenotypic and clinical symptoms resulting from several genetic variants and environmental factors. The unique anatomy and physiology of the eye facilitate validation of cutting-edge gene editing treatments. Genome editing developments have allowed researchers to treat a variety of diseases, including ocular disorders.

Unlabelled: Dry eye disease is a multifactorial disorder of the ocular surface with increasing global prevalence, yet no universally accepted "gold standard" exists for its diagnosis or severity assessment. Tear matrix metalloproteinase 9 (MMP-9) is widely recognized as a valuable biomarker for dry eye, yet there remains a critical need for a simple, accurate, and broadly applicable method for its quantification. This study aims to develop and evaluate a Schirmer strip-based Eu-time resolved fluorescence immunochromatography (Eu-TRFICO) method for the quantitative detection of MMP-9 in tears.
