While rare, extensive dermoids that encroach upon the visual axis carry a poor prognosis. We report the case of a 7-week old premature male infant who presented with large bilateral epibulbar dermoids obscuring the visual axis. He was treated first with sequential bilateral optical iridectomies under the clearest corneal areas, followed several months later by sequential dermoid excision and amniotic membrane transplantation in each eye. He subsequently underwent autologous "simple" oral mucosal epithelial transplantation (SOMET) as well as strabismus surgery. Conclusions and Importance Here we present the first case, to the best of our knowledge, of the use of SOMET in managing post-operative pseudopterygium following dermoid excision. To our knowledge it is the also the first application of this technique in a young pediatric patient. A good clinical outcome may be achieved with SOMET, which may offer a minimally invasive alternative to other traditional modalities.

This is a report of an adult patient showing improvement in visual function from rehabilitation for longstanding homonymous hemianopsia. We present his medical history and visual function testing pre- and post-therapy, demonstrating an improvement in both subjective and objective measures.

A 40-year-old male with history of a ruptured arteriovenous malformation at age 10 years, treated with embolization therapy, was referred to the neuro-ophthalmology clinic for evaluation of right homonymous hemianopsia noted on Humphrey visual field (HVF) testing. At the most recent neuro-ophthalmology exam, the HVF showed a right homonymous hemianopsia with a mean deviation of -11.92 decibels (dB) in the right eye (OD) and -17.97 dB in the left eye (OS). He was referred to visual rehabilitation and showed marked improvement in visual functioning after a standard course of therapy.

The efficacy of visual therapy is demonstrated in the literature. Notably lacking from the literature is a consideration of whether vision rehabilitation is similarly effective in patients that present distantly from the original insult. This case presents the potential for efficacy of visual rehabilitation even decades after the original insult.

The aim of this report is to describe a patient who presented with a central hyper-reflective line (HRL) with spectral domain-optical coherence tomography (SD-OCT) after posterior vitreous detachment that evolved to full thickness macular hole (FTMH) with subsequent spontaneous resolution.

A 59-year-old patient presented with a history of photopsia and floaters followed by the development of a central scotoma in the right eye (OD). The left eye (OS) was normal. On examination, visual acuity (VA) was 20/20- OD and 20/20 OS. Retinal examination OD was remarkable for a retinal tear, and SD-OCT demonstrated a central HRL. The patient underwent laser retinopexy to barricade the retinal tear. Sequential SD-OCT of the macula was performed and the patient eventually developed a small FTMH 8 months after the baseline presentation. VA was correspondingly reduced to 20/80 OD. Upon return after 4 months, the hole was completely resolved with improvement of VA to 20/20 OD.

Vitreomacular traction (VMT) may lead to foveal dehiscence. This instability can be detected with SD-OCT as a vertical hyperreflective stress line that is a risk factor for progression to a FTMH. With release of VMT, FTMH can spontaneously close.

However, it is unclear how far different observers consistently identify contamination hazards and consistently classify water source types using standard typologies. This study aimed to quantify inter-observer agreement in hazard identification and classification of rural water sources. Six observers separately visited 146 domestic water sources in Siaya County, Kenya, in wet and dry seasons. Each observer independently classified the source type and conducted a sanitary risk inspection using a standard protocol. Water source types assigned by an experienced observer were cross-tabulated against those of his colleagues, as were contamination hazards identified, and inter-observer agreement measures calculated. Agreement between hazards observed by the most experienced observer versus his colleagues was significant but low (intra-class correlation = 0.49), with inexperienced observers detecting fewer hazards. Inter-observer agreement in classifying water sources was strong (Cohen's kappa = 0.84). However, some source types were frequently misclassified, such as sources adapted to cope with water insecurity (e.g. tanks drawing on both piped and rainwater). Observers with limited training and experience thus struggle to consistently identify hazards using existing protocols, suggesting observation protocols require revision and their implementation should be supported by comprehensive training. Findings also indicate that field survey teams struggle to differentiate some water source types based on a standard water source classification, particularly sources adapted to cope with water insecurity. These findings demonstrate uncertainties underpinning international monitoring and analyses of safe water access via household surveys.Infants and young children commonly consume apple-based products, which may contain high concentrations of inorganic arsenic (iAs). As yet, iAs exposure from ingesting apple products has not been well-characterized in early childhood. Therefore, we investigated the association between urinary arsenic concentrations and intake of apple products in one-year-old infants participating in the New Hampshire Birth Cohort Study. A three-day food diary prior to collection of a spot urine sample was used to determine infant's consumption of apple products. The sum of urinary iAs, monomethylarsonic acid, and dimethylarsinic acid, referred to as ΣAs, was used to estimate iAs exposure. A total of 242 infants had urinary arsenic speciation analyzed without indication of fish/seafood consumption (urinary arsenobetaine less then 1 μg/L) and with a completed three-day food diary. Of these, 183 (76%) infants ate apples or products containing apple. The geometric mean urinary ΣAs among the 59 infants who did not consume any type of apple product was 2.
