Optical coherence tomography (OCT) has become a very useful tool to study in vivo different ocular structures and to improve differential diagnosis and management of many ocular pathologies. This study aims to identify pterygium alterations that trigger characteristic OCT images, and analyze if this pattern correctly demarcates lesion boundary. Thirty-two(More)
PURPOSE To establish determining factors for fast corneal sensitivity (CS) recovery after pterygium excision. METHODS Thirty-two eyes of 14 males and 18 females with primary nasal pterygium were recruited. Differences in CS (in the 4 quadrants and the center using a Cochet-Bonnet esthesiometer), pterygium corneal area (PCA), tear osmolarity, tear break-up(More)
PURPOSE To analyze the effects of tear hyperosmolarity on conjunctival cells in mild to moderate dry eye. METHODS Sixty-eight subjects (35 females and 33 males, mean age 43, S.D. 20.3, range 18-87 years) with symptoms of dry eye were enrolled in the study. Patients with severe dry eye or any other condition that induces ocular inflammation were excluded.(More)
It is widely accepted that cellular microprojections (microvilli and/or microplicae) of the corneal surface are essential to maintain the functionality of the tissue. To date, the characterization of these vital structures has been made by analysing scanning or transmission electron microscopy images of the cornea by methods that are intrinsically(More)
PURPOSE To analyze conjunctival cytological features 1 month after pterygium excision using limbo-conjunctival autograft (LCA) with and without intraoperative mitomycin C and to assess tissue short-term evolution in both situations. METHODS Fifty-nine primary nasal pterygia from 59 patients were excised with LCA. Twenty-nine were treated with(More)
PURPOSE To establish the sequence of tomographic changes in the tissue recovery process after pterygium excision and to propose healing indicators. METHODS Optical coherence tomography (OCT) images were taken at 1 week, 1, 3 and 6 months after lesion excision in 73 eyes of 73 patients (33 male, 40 female; mean age 50, S.D. 5.0, range 40-70 years) with(More)
PURPOSE To determine abnormalities in tear osmolarity (TO), tear function, and impression cytology in patients with pterygium and to assess the relationship between the variables. METHODS Thirty eyes from 30 patients with primary nasal pterygium and 30 eyes from 30 volunteers without ocular pathologies or dry eye symptoms were enrolled in the present(More)
