The role of anterior segment optical coherence tomography in the evaluation of the pterygium.

Background: To evaluate the ability of anterior segment optical coherence tomography (AS-OCT) to visualize the anatomic features of the pterygium and its invasion of the corneal layers.

Methods: Seventy-five eyes of 54 patients diagnosed with pterygium were included. All subjects underwent complete ophthalmologic examinations, including AS-OCT.

Performance of a photoscreener in detecting accommodation spasm.

Clinical Relevance: For a correct spectacle prescription, accommodation spasm should not be overlooked in the measurements made using an autorefractometer. Although this can be easily understood with cycloplegia, it is not practical. Therefore, investigating practical methods that can predict excess accommodation will be useful in clinical practice.

Ability of non-invasive tear break-up time to determine tear instability in contact lens wearers.

Purpose: To evaluate the performance of precorneal and prelens non-invasive tear break-up time (NIBUT) measurements to determine tear instability in contact lens (CL) wearers.

Methods: In this study, 50 eyes of 25 CL wearers were evaluated. Precorneal first and average NIBUTs and fluorescein tear break-up time (FBUT) were measured before wearing CLs in the morning.

Static and dynamic pupillary characteristics in multiple sclerosis.

Purpose: To examine the static and dynamic pupillary functions with automated pupillography in multiple sclerosis (MS) patients with preserved visual acuity.

Methods: Forty-seven MS patients with preserved visual acuity were included in the study group and 43 healthy volunteers in the control group. The visual evoked potential of the patients was obtained.
