The Sclera and Systemic Disorders (3rd Edition)

An interesting historical introduction captures the reader’s attention as the journey begins into exploring the peculiarities and pathologies of ‘dura tunica of Vesalius’, a term coined by anatomists of the middle ages. This refers to what we today identify as...

Importing iron to the retina

In the retina, iron is particularly critical for the visual phototransduction cascade. In the retinal pigment epithelium (RPE), RPE65 activity leads to 11-cis-retinaldehyde, the photosensitive component of rhodopsin production and iron containing enzymes are necessary for disc replacement in photoreceptor...

Histopathological changes in rabbit retinitis pigmentosa

The authors report the histopathological changes of retinal ganglion cells (RGCs), optic disc and optic nerve in rabbit with advanced retinitis pigmentosa (RP). RP was recreated in rabbits by using bacterial artificial chromosome transgenesis, with the purpose of increasing understanding...

Syndromic V-pattern management

The authors document their experience in the management of four cases of Crouzon syndrome and review the anatomical extraocular muscle anomalies noted during surgery. Horizontal strabismus surgery varied in each of the four cases according to individual extraocular muscle abnormalities...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

Correlation between structural and functional status of optic nerve and retina in multiple sclerosis

Multiple sclerosis (MS) involves autoimmune inflammatory demyelination and axonal degeneration in the central nervous system. Investigation of the retina and optic nerve head (ONH) is an ideal way to visualise this demyelination. This study investigates the functional and structural properties...

Complement Factor H and Factor H-Like protein are expressed in human RPE cells

The role of inflammation in age-related macular degeneration (AMD) is well documented and the association of AMD with the inflammatory marker C-reactive protein (CRP) and members of the complement system underline the role of complements in AMD. Human complement factor...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Risk of CNV related to angioid streaks in PXE

This retrospective cross-sectional study investigated 301 patients with pseudoxanthoma elasticum (PXE) for prevalence of choroidal neovascularisation (CNV) and macular atrophy. Some patients were excluded due to missing or poor-quality imaging or the fact that they didn’t have angioid streaks, leaving...

Changes in drusen and retinal layer volumes prior to CNV development

This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...
