Effect of a punctal plug on ocular surface disease in patients using topical prostaglandin analogues: a randomized controlled trial.

Importance: Ocular surface disease (OSD) is common and can reduce treatment compliance and quality of life.

Background: To determine whether a punctal plug improves OSD and reduces intraocular pressure (IOP) in patients using prostaglandin analogue monotherapy.

Design: Randomized controlled trial.

Compliance with the quality standards of National Diabetic Retinopathy Screening Committee.

Aims: The National Diabetic Retinopathy Screening Committee has recommended 19 standards for quality assurance of screening programmes in the United Kingdom. Five of the standards apply to the care provided by ophthalmology departments. This study assesses the quality assurance of the eye care provided by the Wakefield and North Kirklees Screening programme.
