Introduction: In this study, we investigated the presence of motilin receptors (MR) in adnexal tissue including the human main lacrimal gland.
Method: 17 adnexal human specimens comprising of 11 isolated human main lacrimal gland specimens, four full-thickness human eyelid excisions and two exenterations containing full-thickness eyelid and portions of the main lacrimal gland were immunolabelled with a rabbit polyclonal human MR antibody.
Results: Our results demonstrated that all main lacrimal gland specimens (13/13, 100%) were positive for MR expression with a predominance (10/13 (77%) of grade 1+ punctate distribution.
Statins, 3-hydroxy-3-methyl-gutaryl coenzyme A reductase inhibitors, are a class of lipid-lowering drugs with anti-inflammatory, immunomodulatory, and vascular effects. Statins are increasingly being used in the treatment of a variety of medical conditions. We examine the actions of statins on the eye and its associated ophthalmic disorders.

Purpose: 3-Hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR), the rate-limiting enzyme of cholesterol production, has been found to contribute to lipid secretion from skin sebaceous glands and hair follicles. We assessed for HMGCR expression in human eyelid tissue and in immortalized human meibomian gland epithelial cells (HMGECs) using immunohistochemistry.
Methods: Full thickness human eyelid specimens in archival paraffin blocks were obtained.
Meibomian gland dysfunction is one of the most common ocular disorders encountered by ophthalmologists and is the leading cause of evaporative dry eye. The disease causes significant morbidity in the population such that patients seek treatment. Multiple clinical studies on pharmacological and mechanical interventions for the treatment of meibomian gland dysfunction have been evaluated.

Background: To analyse the association between dyslipidaemia, use of oral statin drugs, and symptoms of dry eye disease (DED) among older adults.
Design: Population-based study.
Background: Iris vascular tufts are rare iris stromal vascular hamartomas. Patients with iris vascular tufts generally remain asymptomatic until presenting with a spontaneous hyphaema or with mild intraoperative pupil margin haemorrhage during anterior segment surgery. This is the first reported case of spontaneous hyphaema from iris vascular tuft related to a documented supratherapeutic International Normalised Ratio as a predisposing factor.

Methods: Ten dry eye and blepharitis (DEB) patients were enroled in a prospective pilot study. All patients were treated with topical atorvastatin (50 μM) 8 times a day for 4 weeks and allowed to continue with their existing dry eye treatment.
HMG-CoA reductase inhibitors (statins) have been demonstrated to be immunomodulatory for human immune-mediated disease and in experimental models. The aim of this study was to compare statin-mediated immunosuppressive effects on human T-cell responses in vitro with those of conventional immunosuppressives (dexamethasone, cyclosporin A (CsA), mycophenolate, and rapamycin). Statins (atorvastatin, lovastatin, and simvastatin) were investigated for their modulatory effects on human PBMC viability, cytokine profiles, and T-cell proliferation.

Further investigation revealed right inferior orbital emphysema, caused by the intra-operative entrance of hydrogen peroxide through a suspected perforation of the orbital septum. The symptoms settled with conservative management.

Method: Case report with histopathological correlation and literature review.
Results: A 61-year-old man presented to the Ophthalmology clinic after he was stung in the left eye by a bluebottle while swimming in the sea.

Purpose: To present a combined interventional radiologic and resection technique for the management of a large amblyogenic, highly vascular lesion of the lower eyelid associated with severe mechanical ectropion, conjunctival pyogenic granuloma, and recurrent, spontaneous conjunctival bleeding.
Methods: Preoperative selective embolization and coil placement were followed by resection of the tumor.
Results: Embolization, coil placement, and resection were uneventful with cosmetic and functional visual improvement obtained.
Common variable immune deficiency (CVID) is characterized by hypogammaglobulinemia, impaired antibody production, and recurrent bacterial infections. Reports of ocular manifestations of CVID are rare. The authors discuss a patient with recurrent keratoconjunctivitis that presented as an initial manifestation of CVID.

Late-onset rheumatoid arthritis (LORA) is a clinically distinct entity from rheumatoid arthritis of younger onset (YORA). We present a case of necrotising anterior scleritis in an elderly lady with new-onset LORA that was initially thought to be infective. Oestrogen receptors have been identified on B cells, T cells, and macrophages with oestrogens demonstrated to increase their activation and enhance RA synovial inflammation.

As a group of disorders, it is responsible for 10% of all registered blind patients under the age of 65 years. Immune-mediated uveitis may be associated with a systemic disease or may be localized to the eye.

Methods: Pooled normal AH was spiked with six cytokines at decreasing concentrations for evaluating the CBA. AH was also obtained from 10 controls (cataract patients) and 36 patients with active uveitis.
Anterior and posterior visual pathway disturbances have been reported post-coronary artery bypass graft surgery. Acute angle-closure glaucoma after general anaesthesia has also been well described in the literature. To date, however, there are only two cases of angle closure caused by tonic pupils.

However, reports of conjunctival involvement in Churg-Strauss syndrome are scarce. Such a presentation is described in a man with Candida albicans infection as well as ankylosing spondylitis, and a possible aetiological linkage is established amongst all three.
