The American Academy of Ophthalmology (AAO) has updated a few more books for the 2019-2020 version of their textbooks. They come with the same clean matt finish, but the colour scheme is a bright sunshine yellow instead of green. Although...

Infantile nystagmus syndrome and use of genetic testing

This review aimed to assess the clinical utility of genetic testing for individuals with infantile nystagmus syndrome. The authors define infantile nystagmus syndrome as having an onset before six months of age, binocular and conjugate. The literature search was conducted...

Effects of market competition on the price of topical eye drops in the US

The authors retrospectively examined the relationship between the number of Federal Drug Administration (FDA)-approved manufacturers and the price change of generic and branded topical eye medications based on the formulations listed in the FDA Orange Book and the National Average...

Differences of the anterior segment parameters in children with Down syndrome

This cross-sectional study was designed in order to demonstrate the differences in anterior segment parameters in children with trisomy 21. This is important as it may impact on surgical planning when undertaking procedures in the anterior segment such as corneal...

Microvascular disease in Alport syndrome

The authors present the findings of a retrospective case-control observational study on increased microvascular disease in individuals with Alport syndrome recruited over a 21-year period. They recruited 28 males and 28 females with X-linked Alport syndrome (XLAS) and eight men...

Driving with retinitis pigmentosa

The authors present a study of 228 consecutive patients with a clinical or genetic diagnosis of retinitis pigmentosa. Data was collected prospectively between January 2012 and October 2022 in Perth, Australia. The study aimed to determine the proportion of patients...

Choroideremia in women

The authors report a questionnaire-based study of female carriers of choroideremia, an X-linked inherited chorioretinal dystrophy. As an X-linked condition the full clinical features are predominantly seen in men but a proportion of women suffer some morbidity, likely due to...
