Orbital exenteration is a disfiguring procedure performed for unresponsive orbital infections and control of recurrent benign tumours and malignancies arising from the eyelids (basal cell carcinoma, squamous cell carcinoma, conjunctival malignant melanoma), lachrymal glands (adenoid cystic carcinoma) or surrounding sinuses. In extremely rare cases the use of a prosthetic eye after enucleation can lead to anophthalmic socket tumours. We report the case of a 54-year-old man who had left eye enucleation due to recurring events of retinal detachment and who developed an invasive fast growing epidermoid carcinoma 30 years later...

Lutein and zeaxanthin are plant pigments known to preferentially accumulate in neural tissue. Macular Pigment Optical Density (MPOD), a non-invasive measure of retinal carotenoids and surrogate measure of brain carotenoid concentration, has been associated with disease prevention and cognitive health. Superior MPOD status in later adulthood has been shown to provide neuroprotective effects on cognition. Given that childhood signifies a critical period for carotenoid accumulation in brain, it is likely that the beneficial impact would be evident during development, though this relationship has not been directly investigated...

Melanocytes, the cells responsible for skin pigmentation, are present in other parts of the body, such as the ocular, auditory, nervous, and cardiac systems. Within these systems, their roles serve a different purpose than their classical counterparts in skin as pigment cells. Such roles include cell turnover in retinal pigment epithelium, maintenance of balance and prevention of environmental damage in the auditory neuroepithelium, role-playing as dendritic cells within the leptomeninges, and prevention of oxidative damage in adipose tissue...

AIMS: Diabetes puts many individuals at risk for developing diabetic retinopathy (DR). Non-mydriatic (NM) retinal photography without pharmacological pupil dilation can be used to detect DR, however, its value in a general clinical setting has not been established. The objective of this review is to evaluate the validity of NM retinal photos, as compared to the reference standard of seven standard stereoscopic 30 degree field photographs (7SF), for their use of detecting DR in community-dwelling adults...

A 44 year old lady presented with acute onset of loss of vision in the right eye and cough with mucopurulent expectoration for two months. Ophthalmic examination revealed central retinal artery occlusion (CRAO). Chest radiograph showed multiple cavitatory nodules with fluid levels. Sputum was negative for AFB and ANCA was strongly positive suggestive of a diagnosis of Granulomatosis with Polyangiitis (GPA). Within the next few weeks the patient had rapid detenoration due to left eye CRAO, progressive bilateral hearing loss, facial palsy and retro orbital mass...

The visual system is involved in different ways in migraine. Visual auras are the most common form of migraine aura. It may consist of positive or negative visual symptoms and cortical spreading depression is felt to be the phenomenon that underlies it. Even in migraine without aura, vision it is not totally excluded given that one of the major criteria for the diagnosis of migraine is photophobia. In persistent visual aura, patients refer symptoms defined as visual snow and television static. In retinal migraine unilateral decreased vision or complete visual loss occurs...

BACKGROUND: Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is now considered the gold standard for the treatment of various retinal disorders. As therapy has evolved, so too have the treatment regimens employed by physicians in clinical practice; however, visual outcomes observed in the real world have typically not reflected those reported in clinical trials. Possible reasons for this include a lack of consensus on treatment regimens and a lack of clarity about what the aims of treatment should be...

Although caspase-2 is a highly conserved protease that has received a lot of research attention, consensus about its roles and the molecular mechanisms that underpin them has been elusive. Recent improvements to our understanding of the activities of caspase-2 have been facilitated by the development and refinement of techniques allowing identification of cellular processes instigated by this caspase. Following DNA damage, caspase-2 can be activated in a molecular complex called the "PIDDosome"; however, other stimuli provoke caspase-2-dependent activities that do not appear to involve this complex...

PURPOSE: Idiopathic macular telangiectasia type 2 (IMT2) is a bilateral acquired maculopathy, with a spectrum of clinical presentations associated with inner retinal telangiectatic vascular anomalies. Cases often are underdiagnosed or misdiagnosed. Current diagnostic modalities such as spectral-domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA) are valuable to the understanding of the clinicopathology. More recently, optical coherence tomography angiography (OCTA), as an emerging noninvasive technology, has been shown to be particularly useful in the assessment and management of IMT2...

"Omics" refers to high-throughput analyses of genes, proteins, or metabolites in a biological system, and is increasingly used for ophthalmic research. These system-based approaches can unravel disease-related processes and are valuable for biomarker discovery. Furthermore, potential therapeutic targets can be identified based on omics results, and targeted follow-up experiments can be designed to gain molecular understanding of the disease and to test new therapies. Here, we review the application of omics techniques in eye diseases, focusing on age-related macular degeneration (AMD), diabetic retinopathy (DR), retinal detachment (RD), myopia, glaucoma, Fuchs' corneal dystrophy (FCD), cataract, keratoconus, and dry eyes...

The outer blood-retina barrier is established through the coordinated terminal maturation of the retinal pigment epithelium (RPE), fenestrated choroid endothelial cells (ECs) and Bruch's membrane, a highly organized basement membrane that lies between both cell types. Here we study the contribution of choroid ECs to this process by comparing their gene expression profile before (P5) and after (P30) the critical postnatal period when mice acquire mature visual function. Transcriptome analyses show that expression of extracellular matrix-related genes changes dramatically over this period...

Ocular ischemic syndrome (OIS) is a collection of symptoms of carotid and ophthalmic artery disease of common genesis accompanied by ischemia of eyeball membranes. Specifically, the intraocular blood flow becomes impaired due to inflow reduction or arrest, while the venous outflow remains patent. Causes of OIS include arterial hypertension, atherosclerosis, diabetes, aortoarteritis and other vascular diseases. Clinical features depend on the extent, nature, and site of vascular involvement as well as the concurrent pathology...

There is increasing awareness on the role played by circadian rhythm abnormalities in neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD). The characterization of the circadian dysfunction parallels the mounting evidence that the hallmarks of neurodegeneration also affect the retina and frequently lead to loss of retinal ganglion cells (RGCs) and to different degrees of optic neuropathy. In the RGC population, there is the subgroup of cells intrinsically photosensitive and expressing the photopigment melanopsin [melanopsin-containing retinal ganglion cells (mRGCs)], which are now well known to drive the entrainment of circadian rhythms to the light-dark cycles...

The mitochondria-associated ER membrane (MAM) plays a critical role in cellular energetics and calcium homeostasis; however, how MAM is affected under diabetic condition remains elusive. This study presented a comprehensive proteome profiling of isolated brain MAM from long-term type 2 diabetic mice vs. non-diabetic controls. MAM protein was extracted efficiently by a surfactant-aided precipitation/on-pellet digestion (SOD) method, and MAM proteome was quantified by an ion-current-based MS1 method combined with nanoLC-MS/MS...

Biomarkers can help unravel mechanisms of disease and identify new targets for therapy. They can also be useful in clinical practice for monitoring disease progression, evaluation of treatment efficacy and risk assessment in multifactorial diseases, such as age-related macular degeneration (AMD). AMD is a highly prevalent progressive retinal disorder for which multiple genetic and environmental risk factors have been described, but the exact etiology is not yet fully understood. Many compounds have been evaluated for their association with AMD...

A novel series of acyl selenoureido benzensulfonamides was evaluated as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors against the human (h) isoforms hCA I, II, VII and IX, which are involved in a variety of diseases such as glaucoma, retinitis pigmentosa, epilepsy and tumors etc. These compounds showed excellent inhibitory activity for these isoforms, with several low nanomolar derivatives identified against all of them. Furthermore, the selenoureido group may provide an antioxidant activity to these enzyme inhibitors...

OBJECTIVE: Advanced glycation end-products (AGEs) constitute a highly heterogeneous family of compounds, relevant in the pathogenesis of diabetic complications, which could represent efficient biomarkers of disease progression and drug response. Unfortunately, due to their chemical heterogeneity, no method has been validated to faithfully monitor their levels in the course of the disease. In this study, we refine a procedure to quantitatively analyze fluorescent AGEs (fAGEs), a subset considered remarkably representative of the entire AGE family, and measure them in in vitro glycated BSA (gBSA) and in plasma and vitreous of diabetic rats, for testing its use to possibly quantify circulating AGEs in patients, as markers of metabolic control...
