REVIEW
Ana Beatriz Diniz Grisolia, Ricardo Christopher Couso, Suzana Matayoshi, Raymond S Douglas, César Augusto Briceño
Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED...

The Rho-kinase/ROCK (Rho-associated coiled-coil-containing protein kinase) pathway is involved in the pathogenesis of multiple ocular and systemic disorders. Recently, ROCK inhibitors have been suggested as novel treatments for various ocular diseases. Several in vitro, in vivo and clinical studies have demonstrated the safety and efficacy of ROCK inhibitors in the management of ocular disorders such as corneal epithelial and endothelial damage, glaucoma, retinal and choroidal neovascularisation, diabetic macular oedema and optic nerve disorders...

Prevention and management of postoperative ocular inflammation with corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) have been evaluated in several randomised controlled trials (RCTs). However, neither consensus regarding the efficacies of different regimens nor established guidelines are currently available. This has resulted in different practice patterns throughout the world. A systematic literature review found that for the management of postcataract inflammation nepafenac produced a positive outcome in three of three RCTs (3/3), as did ketorolac (1/1), bromfenac (7/7), loteprednol (3/3) and difluprednate (6/6), but not flurbiprofen (0/1)...

BACKGROUND/AIMS: To investigate the relationship between gaze tracking (GT) results and ocular surface condition in glaucoma. METHOD: The Humphrey 24-2 visual field (VF) was measured in 34 eyes of 30 patients with open-angle glaucoma without VF damage. Tear break-up time, Schirmer's test, tear meniscus volume (TMV) and presence of superficial punctate keratopathy (SPK) were also measured in order to describe the condition of the ocular surface. Various GT parameters were calculated: the average frequency of eye movements per stimulus between 1° and 2° (move1-2), the average frequency of eye movements per stimulus between 3° and 5° (move3-5), the average frequency of eye movements per stimulus more than 6° (move≥6), the average tracking failure frequency per stimulus (TFF) and the average blinking frequency...
