#1
Tayyab Afghani, Hassan Mansoor
AIMS: This study describes different types of orbital osteoma based on clinical per-operative morphology and radiological findings to facilitate communication between ophthalmologists and surgical management for a better patient outcome. MATERIALS AND METHODS: The study was conducted in the Orbit and Oculoplastics Department of Al-Shifa Trust Eye Hospital, Rawalpindi, Pakistan, from July 1, 2001 to June 30, 2014. A retrospective analysis of 520 diagnosed orbital tumours who presented to us was carried out and the prevalence of orbital osteoma was determined...

REVIEW
M Rudwaleit, K Walscheid, A Heiligenhaus
Acute anterior uveitis (AAU) is the most frequent uveitis subtype. It is often associated with HLA-B27 and with inflammatory rheumatic diseases, in particular with spondyloarthritis (SpA), which itself is strongly associated with HLA-B27. About 40-60% of patients with AAU have an associated spondyloarthritis, and 20-40% of patients with spondyloarthritis also have uveitis. The incidence of AAU in patients with SpA clearly correlates with disease duration. The AAU has an acute onset, usually affects only one eye at a time, and shows a tendency for recurrence...

BACKGROUND: Corneal pathology is one of the leading causes of preventable blindness in South Africa (SA). A corneal transplant can restore or significantly improve vision in most cases. However, in SA there is a gross shortage of corneal tissue available to ophthalmologists. Little has been published describing the magnitude of the problem. OBJECTIVES: To describe trends in the number of corneal donors per year in SA, the number of corneal transplants performed each year, the origin of donors, the allocation of corneas to the public or private sector, and the demographics of donors...

Two patients presented to their ophthalmologists with vision disturbances. On ocular examination, retinopathic lesions were observed. On subsequent examination, these lesions were diagnosed as metastases of breast cancer. Neither patient had a history of breast cancer. In patients with breast cancer and multiple metastases, ocular metastases are well described. However, the latter is uncommon as a presenting complaint.

REVIEW
M Blum, W Sekundo
Refractive lenticule extraction (ReLEx/SMILE) is a refractive surgical method developed by the authors in stages primarily for correction of myopia and myopic astigmatism, in which a femtosecond laser is exclusively used. In the (ReLEx/SMILE) method a refractive lenticule is generated by the femtosecond laser, which is subsequently extracted through a small incision. Opening of the corneal surface with a flap and use of an excimer laser is no longer necessary. In 2013 the method was newly assessed and classified by the Joint Commisssion for Refractive Surgery (KRC) of the Professional Association of Ophthalmologists (BVA) and the German Ophthalmological Society (DOG)...

Gena Heidary
The topic of pediatric neurodegenerative disease is broad and ever expanding. Children who suffer from neurodegenerative disease often have concomitant visual dysfunction. Neuro-ophthalmologists may become involved in clinical care to identify corroborating eye findings when a specific condition is suspected, to monitor for disease progression, and in some cases, to assess treatment efficacy. Ophthalmic findings also may be the harbinger of a neurodegenerative process so a keen awareness of the possible manifestations of these conditions is important...

PURPOSE OF REVIEW: In the last decade, with the advances of optical coherence tomography (OCT) technology, different imaging protocols and analysis algorithms have been introduced to maximize the potential of this diagnostic tool in the evaluation of different eye diseases. This review aims to provide an update on these additional features, with respect to the management of a diverse range of neuro-ophthalmologic conditions. RECENT FINDINGS: Macular ganglion cell complex (mGCC) analysis has been shown to be superior to peripapillary retinal nerve fiber layer (pRNFL) analysis in certain settings, such as differentiating Leber's hereditary optic neuropathy from functional visual loss; monitoring neurodegenerative diseases or multiple sclerosis; and predicting visual loss in nonarteritic ischemic optic neuropathy...

OBJECTIVES: Occipital ischemic strokes typically cause homonymous visual field defects, for which means of rehabilitation are limited. Intravenous thrombolysis is increasingly and successfully used for their acute treatment. However, recognition of strokes presenting with mainly visual field defects is challenging for both patients and healthcare professionals. We studied prehospital pathways of occipital stroke patients with mainly visual symptoms to define obstacles in their early recognition...

OBJECTIVE: The purpose of this study was to evaluate the efficacy and safety of 0.1% tacrolimus eye drops in the tarsal form of vernal keratoconjunctivitis (VKC) and to survey the changes of dendritic cells at the palpebral conjunctiva in patients with VKC by in vivo confocal microscopy. METHODS: A total of 17 patients (34 eyes) with the tarsal form of VKC were enrolled in this prospective, nonrandomized case series. They were treated with 0.1% tacrolimus eye drops twice daily after discontinuation of all other topical medications...

Telangiectasias are prominent small vessels (venules, capillaries or arterioles) that are visible as small red-purple focal lesions in the skin and mucous membranes. They can serve as a cutaneous marker for a number of primary (mostly hereditary) disorders and they can be secondary to other (systemic) diseases. Patients with telangiectasias are seen by general health practitioners, pediatricians, (pediatric) neurologists, dermatologists, and ophthalmologists. In this article we give an overview of the different disorders in which telangiectasias are a prominent feature, focusing on neurocutaneous disorders in which they serve as a marker for establishing the right diagnosis...

About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. The sphenoid sinuses are rarely involved. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. Thus, barotrauma could lead to serious neurologic disorders, including blindness. After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge...

PURPOSE: Dry eye symptoms greatly impact patients' quality of life in ocular graft-versus-host disease (oGVHD). Various ocular surface changes have been reported in oGVHD, including meibomian gland atrophy (MGA) and clinical conjunctival scarring or subepithelial fibrosis (CSEF). The relationships between CSEF, MGA, and other ocular surface changes in oGVHD were examined. METHODS: Charts of 21 consecutive GVHD patients examined by a single ophthalmologist were retrospectively reviewed...

BACKGROUND: To investigate the outcomes of glaucoma referrals across different European countries. METHODS: 250 patients newly referred to tertiary referral glaucoma specialist practices in the UK, Hungary, Slovenia, Italy and Greece were prospectively enrolled (50 consecutive patients per centre). Referral accuracy and predictive value of referral criteria for an intervention or further monitoring (positive predictive value) were analysed. RESULTS: Same-day discharges occurred in 43% (95% CI 39% to 75%) (12/28) of optometrist-initiated referrals (UK only), 37% (95% CI 30% to 45%) (59/158) of ophthalmologist-initiated referrals (all centres) and 54% (95% CI 40% to 68%) (26/48) of self-referrals (Hungary, Italy and Greece)...
