REVIEW
Christopher T Leffler, Stephen G Schwartz
INTRODUCTION: John Thomas Woolhouse (1666-1733/1734), who practiced in Paris, was part of a family with 5 generations of English oculists. Some historians have derided him as a "charlatan" and have criticized him for adhering to the old notion that a cataract was a membrane anterior to the lens. METHODS: We reviewed treatises and digital records related to Woolhouse and his family and the handwritten notes of his 1721 lecture series at the Royal Society of Medicine...

Jiwei He, Alisa Stephens-Shields, Marshall Joffe
Marginal structural models are a class of causal models useful for characterizing the effect of treatment in the presence of time-varying confounding. They are more widely used than structural nested models, partly because these models are easier to understand and to implement. We extend marginal structural models to situations with clustered observations with unit- and cluster-level treatment and introduce an appropriate inferential method. We consider how to formulate models with cluster-level and unit-level treatments...

c-Jun, c-Jun N-terminal kinase(JNK) and endothelin B (ETB) receptor have been shown to contribute to the pathogenesis of glaucoma. Previously, we reported that an increase of c-Jun and CCAAT/enhancer binding protein β (C/EBPβ) immunohistostaining is associated with upregulation of the ETB receptor within the ganglion cell layer of rats with elevated intraocular pressure (IOP). In addition, both transcription factors regulate the expression of the ETB receptor in human non-pigmented ciliary epithelial cells (HNPE)...

Primary open-angle glaucoma (POAG) is often caused by elevated intraocular pressure (IOP), which arises due to increased resistance to aqueous humor outflow (AHO). Aqueous humor flows through Schlemm's canal (SC), a lymphatic-like vessel encircling the cornea, and via intercellular spaces of ciliary muscle cells. However, the mechanisms underlying increased AHO resistance are poorly understood. Here, we demonstrate that signaling between angiopoietin (Angpt) and the Angpt receptor Tie2, which is critical for SC formation, is also indispensable for maintaining SC integrity during adulthood...

The familiar amyloid polyneuropathy (FAP) is a rare autosomal-dominant systemic amyloidosis. Amyloid deposition occurs more frequently and extensively in the vitq. The increase in intraocular pressure (IOP) is a result of deposition of transthyretin (TTR) in trabecular meshwork. Rarely, the amyloid deposition in anterior segment can be more exuberant than in posterior segment. A 42 years old man, with FAP (Val30Met mutation), liver transplantation in 1997. He was asymptomatic, without any significant ocular abnormality until 2011...

Glaucoma secondary to penetrating keratoplasty can be challenging and multiple surgeries may be needed to control the intraocular pressure (IOP), including the use of glaucoma drainage implants. However, late failure of these drainage implant surgery is common, mostly because of excessive scarring or bleb encapsulation which may require further surgical intervention. We present a case of a young patient referred for advanced glaucoma secondary to penetrating keratoplasty and chronic uveitis. He presented with elevated IOP under maximal therapy, already with 2 failed trabeculectomies and a nonfunctional Ahmed Valve...

Progressive neurodegeneration of the optic nerve and the loss of retinal ganglion cells is a hallmark of glaucoma, the leading cause of irreversible blindness worldwide, with primary open-angle glaucoma (POAG) being the most frequent form of glaucoma in the Western world. While some genetic mutations have been identified for some glaucomas, those associated with POAG are limited and for most POAG patients, the etiology is still unclear. Unfortunately, treatment of this neurodegenerative disease and other retinal degenerative diseases is lacking...

Graves ophthalmopathy (GO) usually occurs in a close temporal relationship with hyperthyroidism. It is rare in patients with normal thyroid function (euthyroid GO) and in patients with hypothyroid forms of thyroid autoimmune diseases (hypothyroid GO). We report a 52-years old man presenting in our endocrine clinic with diagnosed primary hypothyroidism 3 months back during evaluation for glaucoma. He was later referred by an ophthalmologist to exclude Grave's eye disease, where he had presented with chief complaints of bilateral prominent eyes...

Secondary Acute Angle Closure Glaucoma (AACG) is a known side effect of Topiramate (TPM). Here, we present a case report of a 47-year-old male who was started on TPM 25 mg/day for migraine. He presented to the ophthalmology department of our hospital with sudden blurring of vision and colored halos after one day of starting TPM. A high index of suspicion, followed by appropriate investigations and prompt management that helped to manage TPM induced bilateral AACG with quick and complete visual recovery.

The effect of celebrity diagnosis on public awareness of health conditions has already been well documented. In October 2014, Bono, the lead singer with U2, revealed publicly for the first time that he has glaucoma. This study aimed to analyze the impact of Bono's announcement on public awareness of glaucoma using Google Search trends as an indicator of public interest in the disease. Google Trends was used to examine Google Search activity for the term 'Glaucoma' between 2009 and 2015 in both Ireland and the United Kingdom...

In this review, we summarize the progression of several parameters assessed by spectral-domain optical coherence tomography (SD-OCT) in recent years for the detection of glaucoma. Monitoring the progression of defects in the retinal nerve fiber layer (RNFL) thickness is essential. Imaging and analysis of retinal ganglion cells (RGCs) and inner plexiform layer (IPL), respectively, have been of great importance. Optic nerve head (ONH) topography obtained from 3D SD-OCT images is another crucial step. Other important assessments involve locating the Bruch's membrane opening (BMO), estimating the optic disc size and rim area, and measuring the lamina cribrosa displacement...

Glaucoma is one of the leading causes of blind worldwide. Post-operative scar formation of filtering tract was one of the main reasons for failure of glaucoma filtration surgery. In this study, we conducted several experiments to detect the expression of miR-26a in the scar tissue in filtering tract and then detect its potential biological effects as well as its target gene. In our present study, it was found that miR-26a was significantly down-regulated in filtering tract scar. Advanced study on the association between the miR-26a and connective tissue growth factor (CTGF) micro RNA (mRNA) showed that miR-26a was inversely correlated with CTGF mRNA level...

BACKGROUND: The association of the WDR36 gene with glaucoma has been controversial in the literature. We therefore conducted a systematic review and meta-analysis to assess the association of all reported common polymorphisms in WDR36 with primary open angle glaucoma (POAG) and its subtypes: high tension glaucoma (HTG) and normal tension glaucoma (NTG). METHODS: Publications in PUBMED and EMBASE databases up to March 9, 2016 were searched for case-control association studies of WDR36 with POAG, HTG, and/or NTG...

Purpose: Understanding the role of mitochondria in retinal ganglion cells (RGCs) is relevant to human disease as studies have shown mitochondrial abnormalities in primary open-angle glaucoma patients. This study seeks to determine the effects of the sigma-1 receptor (σ-1r) and its agonists on mitochondrial function in oxygen- and glucose- deprived (OGD) purified neonatal RGCs. Methods: Retinal ganglion cells were isolated from rat pups and subjected to OGD in varying conditions in the presence or absence of σ-1r agonist and antagonist and following addition of an AAV2-σ-1r vector that was used to increase σ-1r expression...
