Tear Film Instability and Meibomian Gland Dysfunction Correlate with the Pterygium Size and Thickness Pre- and Postexcision in Patients with Pterygium

<div>(a) Anterior segment SD-OCT horizontal OCT scan (parallel to the axis of the midpoint of the cornea on the nasal and particular sides) of a primary pterygium. (b) Anterior segment SD-OCT measures the thickness of pterygium at 1 mm in the limbus. The primary pterygium is the overgrown section attached to the cornea. The value of 251 <i>μ</i>m represents the thickness of the pterygium at 1 mm in the limbus. The pterygium is present between the two arrows.</div>
