Fuchs’ Endothelial Corneal Dystrophy: Subjective Grading versus Objective Grading Based on the Central-to-Peripheral Thickness Ratio

by  •  • 0 Comments

Purpose:
To assess interobserver agreement between 2 corneal specialists grading Fuchs’ dystrophy clinically and to determine if the corneal central-to-peripheral thickness ratio (CPTR) may be an alternative and objective metric of disease severity.

Design:
Cross-sectional study.

Participants:
Forty-five eyes (26 subjects) with mild and moderate Fuchs’ dystrophy, 73 eyes (60 subjects) with advanced Fuchs’ dystrophy, and 267 eyes (142 subjects) with normal corneas.

Methods:
Corneas with Fuchs’ dystrophy were graded by 2 corneal specialists based on the confluence and area of guttae and the presence or absence of edema. Central (Read more...)

Functional Improvement after One- and Two-Eye Cataract Surgery in the Salisbury Eye Evaluation

by  •  • 0 Comments

Purpose:
To determine the impact that cataract and cataract surgery have on clinical measurements of vision, reading speed, objective mobility performance, and subjective visual functioning.

Design:
Prospective, population-based study.

Participants:
A total of 1739 Salisbury Eye Evaluation (SEE) participants without previous cataract surgery with bilateral baseline best-corrected visual acuity (BCVA) of logarithm of the minimum angle of resolution (logMAR) ≤0.3 (≥20/40) or cataract surgery between rounds 1 and 2.

Methods:
Participants were categorized on the basis of cataract surgery by round 2 into no surgery, unilateral surgery, or bilateral surgery. (Read more...)

Seasonal Changes in Visual Field Sensitivity and Intraocular Pressure in the Ocular Hypertension Treatment Study

by  •  • 0 Comments

Purpose:
Longitudinal testing plays a key role in glaucoma management. Variability between visits hampers the ability to monitor progression. It has previously been shown that average intraocular pressure (IOP) exhibits seasonal fluctuations. This study examines whether visual field sensitivity also exhibits seasonal fluctuations and seeks to determine whether such fluctuations are correlated to seasonal IOP effects.

Design:
Comparative case series.

Participants:
A total of 33 873 visits by 1636 participants enrolled in the Ocular Hypertension Treatment Study. Participants were split into 6 geographic zones according to the prevailing climate in (Read more...)
