The effect of intravitreal injections on dry eye, and proposed management strategies.

Intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents has become a commonly used treatment method for a number of ophthalmic conditions, including age-related macular degeneration. Although anti-VEGF therapy has shown promising results for many patients, there are several aspects of its application that have not been thoroughly investigated. One of these is the development and/or escalation of concurrent dry eye syndrome. Many patients undergoing treatment are already predisposed to dry eye disease due to their age and overall ocular health. As dry eye can have a substantial impact on quality of life, it has become increasingly apparent that the clinical signs and symptoms should be closely monitored and aggressively managed. This will allow for the optimization of patient comfort and visual potential. Here, we discuss the reasons why dry eye may develop during the course of repeated ocular anti-VEGF therapy, highlighting the key concerns about current practices and proposing possible solutions to improve the outcome for the patients.

The association of refractive error, strabismus, and amblyopia with congenital ptosis.

PURPOSE: To determine the frequency of amblyopia and its associations among children with congenital ptosis. METHODS: A retrospective chart review of 92 active patients with congenital ptosis in the practices of 2 of the authors. The main outcome measures were relative eyelid ptosis severity, presence and type of strabismus, refractive error, and amblyopia. RESULTS: Amblyopia was identified in 22 of 92 patients (23.9%), in almost every case occurring in the context of coexisting anisometropia or strabismus and affecting the eye with the more severe ptosis (P = 0.0001). Amblyopia was more likely to occur in cases with greater relative eyelid asymmetry and did not develop in children with symmetric ptosis. In several cases, anisometropia and amblyopia were not initially apparent but progressively developed during follow-up. CONCLUSIONS: Children with congenital ptosis are at risk of anisometropic and strabismic amblyopia, which may progress during early development. Patients should be examined at regular intervals to evaluate and treat these potential complications.
