Dry eye disease, Schirmer I test, clinical tests, large population of patients, tear production levels
Dry eye disease (DED) is multifactorial, caused by an alteration in the quality or quantity of tear film’s three layers. Several tests are available for diagnosis. The aim of this study was to determine if the Schirmer test (ST) could...

Ocular surface disease (OSD) is common in patients chronically treated for glaucoma. This may be related to the drug itself but often to the preservatives in the medication. Much work has been done on the most common preservative, benzalkonium chloride...
Conjunctivochalasis and aqueous tear deficiency – which one causes symptoms?

Cornea / External Eye Disease
This review sought to determine whether conjunctivochalasis (CCh) obliterates the fornix tear reservoir and thus mimics aqueous tear deficiency (ATD). Patients were divided into two groups, with aqueous tear deficiency (CCh +ATD) or without (CCh –ATD), based on results of...

The authors assessed the lacrimal outflow resistance with a modified irrigation system. The manometric tear duct test (mTDT) comprised of a 6mm thin wall 25 gauge lacrimal cannula which was attached to a bag of normal saline by standard fluid...
Tear film thickness after treatment with artificial tears in patients with moderate dry eye disease

Cornea / External Eye Disease
In recent years artificial tear drops addressing tear film osmolarity have come onto the market. Increased tear evaporation and reduced tear volume results in tear hyperosmolarity. This triggers an inflammatory process leading to apoptosis of goblet and epithelial cells. Trehalose,...

Corneal curvature, dry eye, impression cytology, keratoconus, scleral contact lens
This study of 16 keratoconus patients aimed to investigate the impact of long-term scleral contact lens (ScCL) wear on corneal curvature, corneal thickness, tear film function and ocular surface in patients with keratoconus. Corneal topography, tear osmolarity test, Schirmer 1...
Simple approach to prevent capsule tear-out during capsulorhexis creation in hyper mature cataracts

Cataract and Refractive
Puncturing the anterior capsule in the anterior chamber so that the pressure falls below intracapsular tension causes the rhexis to extend out to the equator. If this develops into a tear that wraps around the entire lens it is called...
Dry eyes after photorefractive keratoplasty

Cornea / External Eye Disease
This study examined changes in tear break up time (TBUT), Schirmer test, tear osmolarity and dry eye questionnaire (OSDI) score from prior to photorefractive keratoplasty (PRK), to two months and four months postoperatively. Fifty eyes of 25 patients were examined....

This paper is an update on the assessment and management of dry eye disease (DED). According to the second International Dry Eye Workshop 2017, “Dry eye is a multifactorial disease of the ocular surface characterised by a loss of homoeostasis...
RPE tears after intravitreal Lucentis

Retina / Uvea / Vitreous
The current hypothesis regarding retinal pigment epithelium (RPE) tears is the contraction and fibrosis in choroidal neovascularisation (CNV) tissue after anti-VEGF therapy can induce rips in the overlying RPE. This South Korean study aimed to identify the association between RPE...
