purpose: to evaluate changes in tear condition following unilateral ptosis surgery. methods: in this case series all patients with unilateral ptosis who underwent ptosis surgery over a two-year period were studied. the patients did not have history of previous eye surgery or other eye problems. eyelid and lacrimal evaluation included schirmer’s test with and without anesthesia and tear break up...

PURPOSE We measured tear film parameters, including the morphology and function of meibomian glands, in junior high school students at 15 years of age. METHODS A total of 111 eyes of 111 students (56 males and 55 females) were enrolled in the study. The ocular symptom score (0-14), after-school study time, lipid layer thickness (LLT) of the tear film, partial blink rate, lid margin abnormalit...

Hormone replacement therapy (HRT) for dry eye syndrome (DES) is controversial in clinical practice. The goal of this study was to review relevant studies and analyze the pooled data to determine whether HRT is effective for DES. In this study, a literature search of PubMed, Embase, and Cochrane databases up to May 2015 was performed, with the search restricted to English language publications. ...

AIM To investigate ophthalmologic findings in children with thalassemia major (TM) and compare the findings with healthy controls. METHODS In a cross-sectional study, 43 children with thalassemia major from pediatric hematology outpatient clinics from two university hospitals and age/sex matched 47 healthy children were included in the study. After a complete ophthalmic examination, tear func...

PURPOSE To compare tear epidermal growth factor (EGF) concentration in dry eye (DE) conditions and determine correlations between EGF levels and severity of symptoms and ocular surface signs. METHODS In this prospective case-control study, 35 patients with DE, including subgroups with meibomian gland disease (MGD), Sjögren's syndrome (SS) aqueous tear deficiency, or neurotrophic keratopathy (...

This study aimed to evaluate changes in lacrimation and intraocular pressure (IOP) in dogs with unilateral corneal ulceration using the Schirmer tear test (STT) and rebound (TonoVet®) tonometry. IOP and STT values were recorded in both ulcerated and non-ulcerated (control) eyes of 100 dogs diagnosed with unilateral corneal ulceration. Dogs presented with other ocular conditions as their primary...

Schirmer proved that there is a class of smooth self-maps of the unit sphere in Euclidean n-space with the property that any smooth self-map of the unit ball that extends a map of that class must have at least one fixed point in the interior of the ball. We generalize Schirmer’s result by proving that a smooth self-map of Euclidean n-space that extends a self-map of the unit sphere of that clas...

This study compared tear function tests and cytologic changes on the conjunctival surface in asymptomatic patients wearing contact lens of different materials. Included in this study were 40 eyes wearing daily wear 4 week replacement hydrogel (H) lenses, 32 eyes wearing silicone hydrogel (SiH) lenses, 18 eyes wearing rigid gas-permeable (RGP) lenses, and 21 healthy eyes (no lenses) as the contr...

Purpose. To evaluate the relationship between corneal and conjunctival epithelium thickness and ocular surface clinical tests in dry eye disease (DED) patients. Patients and Methods. Fifty-four patients with DED and 32 control subjects were included. Each patient underwent an ocular surface evaluation using the ocular surface disease index (OSDI), tear film break-up time (TBUT), corneal and con...

A fundamental problem in concurrent system design is to identify flexible programming disciplines under which weak memory models provide sequential consistency. For x86-TSO, a suitable reduction theorem for threads that communicate only through shared memory was given by Cohen and Schirmer [5]. However, this theorem cannot handle programs that edit their own page tables (e.g. memory mangers, hy...
