From Current Opinion in Ophthalmology : Purpose of review: This article will discuss the management of isolated, acute cranial nerve 3,4 and 6 palsies with special focus on the role of neuroimaging in older adults based on recently published data. Recent findings: Acute cranial nerve palsies affecting the third, fourth or sixth cranial nerves in isolation or in combination with other neurological signs and symptoms can be due to a variety of causes such as ischemia, inflammation, infection and compression of the ocular motor nerves. Although neuroimaging is generally recommended in all individuals presenting with ocular motor nerve palsies that occur in association with other neurological signs and symptoms, the indications for neuroimaging in older individuals (age > 50 years) who present with acute isolated ocular motor nerve palsies are less clear and controversial. Past and recent studies have attempted to address this question. A recent prospective study found that overa...

From Journal of Cataract and Refractive Surgery: Femtosecond laser–assisted cataract surgery yielded faster visual recovery, less deviation from the target refraction, and earlier stabilization of refraction.

From Journal of Refractive Surgery : The ICL PIOL provided good refractive outcomes and stability in the long term. The incidence of cataracts is low when the latest models of this PIOL are used.

From International Journal of Rheumatic Disease : Dry eye and impaired tear function in patients with vitamin D deficiency may indicate a protective role of vitamin D in the development of dry eye, probably by enhancing tear film parameters and reducing ocular surface inflammation. Patients with vitamin D deficiency should be evaluated for dry eye syndromes.

Abstract from Current Opinion in Ophthalmology : Purpose of review : Dry eye syndrome can be difficult to manage in severe or refractory cases. In patients in whom traditional treatments have limited efficacy, alternative treatments may be considered for dry eye syndrome, including scleral lenses. The present review summarizes the evidence regarding scleral lens use in dry eye syndrome. Recent findings : Scleral lenses have become a viable option for severe dry eye syndrome, and have been shown to be efficacious and well tolerated, with most reports citing improved visual acuity and relief of symptoms. Currently, there are 18 manufacturers of scleral lenses, although published reports on scleral lenses primarily focus on the BostonSight PROSE and the Jupiter Lens. Summary : Scleral lenses are efficacious and well tolerated for use in severe dry eye syndrome. Further research is needed to compare different sizes and types of lenses, and to standardize outcome measures.

From Eye : We demonstrated that vitamin D deficiency decreases the TBUT and Schirmer test values and may be associated with dry-eye symptoms in non-Sjögren syndrome.

From Clinical Ophthalmology : Vitamin D levels for most PSC patients fell below the 30 ng/mL calcium homeostasis threshold. Some comorbidities and non-ophthalmic interventions are associated with the development of PSC at less depressed levels of 25-OH D. In this series, vitamin D deficiency was associated with PSC cataract, suggesting that raising the level of vitamin D intake may reduce PSC incidence.
