Seventy-six pterygium cases and 152 age-and- sex matched controls presenting to the OPD of Manipal Teaching Hospital were included. The TBUT Schirmer's test and basa...

Among the many explanations for the large biological diversity of Mexico is that it is the result of the contact between the Nearctic and Neotropical biotas; however, this contact-related explanation is not fully satisfactory and needs further examination in the light of historical biogeography. We offer newer insights into this issue by examining the history of the flora and the vegetation het...

purpose: to investigate tear function in acne vulgaris patients who were treated with isotretinoin (accutane). methods: in this prospective clinical study, patients who were scheduled for isotretinoin (accutane) therapy for two months underwent complete eye examination.the best corrected visual acuity measurement, careful slit lamp examination of anterior segment, evaluation of break-up-time an...

purpose: to report a case of duane's retraction syndrome with dry eye. patient and findings: an 18-year-old girl presented with chief complaint of limited abduction in her right eye. best corrected visual acuity was od: 8/10 and os: 9/10. ocular motility examination revealed severe abduction limitation (-4), mild adduction limitation (-1), and moderate upshoot and mild downshoot in the rig...

purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

CASE PRESENTATION Dobesilate administered as eye drops was well tolerated and effective in treating both the objective signs and subjective symptoms of dry eye disease in this 2-week study. CONCLUSION To the best of our knowledge, this is the first clinical report of u...

Dry eye syndrome is one of the most commonly reported eye health conditions. Dynamic-area high-speed videokeratoscopy (DA-HSV) represents a promising alternative to the most invasive clinical methods for the assessment of the tear film surface quality (TFSQ), particularly as Placido-disk videokeratoscopy is both relatively inexpensive and widely used for corneal topography assessment. Hence, im...
