Purpose To explore how finite-element calculations can continue to contribute to diverse problems in ophthalmology and vision science, we describe our recent work on modeling the force on the peripheral…
OBJECTIVE To evaluate the pattern of vision loss and genotype-phenotype correlations in WFS1 -associated optic neuropathy (WON). DESIGN Multicenter cohort study. METHODS The study involved 37 patients with WON carrying…
Purpose To determine the visual outcomes and effectiveness of glaucoma surgeries in congenital ectropion uvea. Design Retrospective interventional case series. Methods Surgeries and examination findings were collected on 11 eyes…
Purpose To quantify potential loss (loss of vision) and gain (freedom from metastasis) in patients with small choroidal melanoma treated after a period of surveillance to document growth. Methods A…

Ultrasound is an indispensable tool in medical imaging and plays an essential role in ophthalmologic diagnoses. It is the most critical imaging technique in eyes with opaque media. This chapter…
In 1960 Novotny and Alvis performed the first successful fluorescein angiogram on a human being using black-and-white film. That event marked the advent of modern ophthalmic photography. Subsequent development of…
Antiquity No one knows when the earliest vision aids were used. There are no written recordings from early times. No paintings or sculptures showing optical devices or specimens from these…
Introduction and basics Computerized corneal topography analysis is the measurement of the curvature of the corneal surface. This tool is based on the principles of keratometry and photokeratoscopy developed in…
