ABSTRACT Acute ocular hypertension during hemodialysis is a rare event and may lead to interruption of dialytic therapy due to pain. A case of a 70-year-old male patient is reported, who presented recurrent intense unilateral ocular pain episodes during dialysis sessions for increased intraocular pressure. The patient presented with severely decreased visual acuity in the right eye due to neovascular glaucoma, which was controlled with topical hypotensive medication. One hour after initiating dialysis, he presented an excruciating pain on the […]

Purpose: Polycystic ovary syndrome (PCOS) is an endocrine disease characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect tear function. This study evaluates tear function and impact of hyperandrogenism on it in PCOS patients. Methods: Fifty patients with PCOS and thirty control volunteers were examined for tear break-up time, Schirmer-I and tear osmolarity. Also, serum levels of total testosterone, FSH, LH and AMH were determined in venous blood samples in the early follicular phase. PCOS patients were divided into […]

Purpose: Describe an animal model of dry induced by topical instillation of BAK and evaluate ocular surface biomarkers and histological findings. Methods: Male Wistar rats were used.Topical instillation of 0.2% BAK eyedrops twice a day during 7 days, in the right eye of each animal, while the other eye was taken as control. After 7 days treatment, we performed evaluation of tear film osmolarity, the red phenol thread and ocular surface staining with fluorescein and lissamine green. Afterwards, the animals […]
