European Glaucoma Society Terminology and Guidelines for Glaucoma, 4th Edition - Chapter 2: Classification and terminology * Supported by the EGS Foundation: Part 1: Foreword; Introduction; Glossary; Chapter 2 Classification and Terminology
2Classification and Terminology2.1- Primary Congenital Forms/Childhood Glaucomas Primary congenital glaucoma is a rare disease but has a major impact on the child’s development and quality of life over his/her whole life span. Early diagnosis and appropriate therapy can make a huge difference in the visual outcome and can prevent lifelong disability. Surgical treatment is always necessary1, 2 [I,C]. 2.1.1Primary congenital glaucoma (PCG): from birth to >2 years of life Neonatal or newborn onset (0-1 month) Infantile onset (>1 until 24 months) Late onset or late recognized (>2 years) Spontaneously non-progres...

Vision impairment and major eye diseases reduce vision-specific emotional well-being in a Chinese population
Conclusions Severe VI and glaucoma are associated with substantial decrements in vision-specific emotional well-being, highlighting the importance of preventing progression of vision loss. Evidence-based interventions to improve vision-related coping skills and emotional management for patients with severe VI and glaucoma are warranted. (Source: British Journal of Ophthalmology)

Long-term complications of different porous orbital implants: a 21-year review
Conclusions Late exposures of porous orbital implants were noted during long-term follow-up. The causes of implant exposure may be associated with pegging procedures and evisceration. The implantation of dermis fat can be an effective procedure for the management of large-area implant exposure. (Source: British Journal of Ophthalmology)

Progression of asymptomatic optic disc swelling to non-arteritic anterior ischaemic optic neuropathy
Conclusions Current treatment options for NAION once vision loss occurs are limited and may not alter the natural history of the disorder. Subjects with NAION may have disc swelling for 2–10 weeks prior to the occurrence of visual loss, and with the development of new therapeutic agents, treatment at the time of observed disc swelling could prevent vision loss from NAION.

Retinal reattachment and ERG recovery after ophthalmic artery chemosurgery for advanced retinoblastoma in eyes with minimal baseline retinal function
Conclusions Minimal baseline ERGs do not preclude significant recovery of retinal function after OAC. Good correlation exists between ERG outcomes at 3 months and those at subsequent follow-ups, suggesting that ERG amplitudes at 3-month post-OAC can prognosticate longer term retinal function, and that improvement is durable. For eyes presenting with RD, RD resolution is necessary but not sufficient for significant (≥25 μV) increases in ERG amplitudes. (Source: British Journal of Ophthalmology)

The impact of typical neovascular age-related macular degeneration and polypoidal choroidal vasculopathy on vision-related quality of life in Asian patients

Putative protective role of lutein and zeaxanthin in diabetic retinopathy
Diabetic retinopathy (DR) is one of the most important microvascular complications of diabetes and remains the leading cause of blindness in the working-age individuals. The exact aetiopathogenesis of DR remains elusive despite major advances in basic science and clinical research. Oxidative damage as one of the underlying causes for DR is increasingly being recognised. In humans, three hydroxycarotenoids, lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ), accumulate at the central retina (to the exclusion of all other dietary carotenoids), where they are collectively known as macular pigment. These hydroxycarotenoids by...

Improving services for glaucoma care in Nigeria: implications for policy and programmes to achieve universal health coverage
Glaucoma in Africa is sometimes referred to as the silent thief of sight. In Nigeria, glaucoma is common, it is serious, ophthalmologists face many constraints in managing it, people do not even know they have it until it is advanced, patients do not understand or comply with treatment after they are diagnosed and the poor are more likely to be glaucoma blind. Available evidence indicates that the health system in Nigeria is failing to meet the needs of patients with glaucoma. Based on evidence, we propose future directions for improving services for glaucoma care in Nigeria, and the implications for policy and programmes ...

Crowded letter and crowded picture logMAR acuity in children with amblyopia: a quantitative comparison
Conclusions The Kay Picture test consistently overestimated VA by approximately 0.10 logMAR when compared with the Keeler Letter test in young children with amblyopia. Due to the predictable difference found between both crowded logMAR acuity tests, it is reasonable to adjust Kay Picture acuity thresholds by +0.10 logMAR to compute expected Keeler Letter acuity scores.

Repeatability of automated vessel density measurements using optical coherence tomography angiography
Conclusions Commercial automated vessel density measurements using OCT-A showed excellent repeatability in healthy individuals. Although repeatability will also need to be established in the setting of disease, the level of reproducibility should be useful for assessing the significance of differences in capillary density over time or under different conditions.
