Diabetic Macular Edema (DME) is a severe eye disease that can lead to irreversible blindness if it is left untreated. DME diagnosis still relies on manual evaluation from opthalmologists, thus the process is time consuming and diagnosis may be subjective. This paper presents two novel DME detection frameworks: (1) combining features from three pre-trained Convolutional Neural Networks: AlexNet, VggNet and GoogleNet and performing feature space reduction using Principal Component Analysis and (2) a majority voting scheme based on a plurality rule between classifications from AlexNet, VggNet and GoogleNet...

The nasolacrimal drainage apparatus (NDA) is of interest to anatomists, radiologists, and ophthalmologists alike, owing to its intricate luminal contour, complex surrounding structural morphology, and its clinical relevance. Here, we review the history of anatomical descriptions of so-called luminal "valves" of the NDA, including the numerous historical figures whose eponyms adorn the NDA. By 1908, multiple false "valves" that are likely no more than mounds of mucosa along the NDA had been recorded...

Diabetes mellitus (DM) is a complex and chronic metabolic disorder leading to many complications. One of the most common complications of DM is diabetic neuropathy. There are many studies exploring corneal sensitivity as a potential marker of diabetic neuropathy. This review aims to explore association between corneal sensitivity and diabetic neuropathy. In diabetic neuropathy, corneal sensitivity is impaired due to low level of corneal nerve trophic factors, impaired sensory nerve fibers, and lost communication of dendtritic cell...

Penetrating Keratoplasty in high risk cases like paediatric patients, complicated cases of pseudophakic bullous keratopathy, or in patients with highly vascularized corneal opacities have been a challenge for opthalmologists because of the poor outcome. 101 patients with such high risk indications underwent penetrating keratoplasty. Some of them also underwent concurrent procedures like PC IOL implantation or vitrectomy. The patients' follow up period ranged from six months to four years. The results were evaluated...

REVIEW
Brian A Darlow
Blindness from retinopathy of prematurity (ROP) in Australian and New Zealand is an uncommon event although 3% of <31 weeks gestation infants receive treatment for the disease. New world-wide estimates of the incidence of blindness from ROP are much higher than previously at 20 000 children annually. The impact of severe ROP can be reduced through good evidence-based care of very preterm infants and careful organisation of eye examinations and follow-up services. Recent oxygen saturation targeting trial results might mean the adoption of higher targets than formerly in very preterm infants and will require vigilance to ensure all eligible infants are examined appropriately...

BACKGROUND: Ochronosis/Alkaptonuria is a tyrosine metabolism disorder where accumulation of homogentisic acid, in eye, skin, cartilage and several other connective tissues leads to a black pigmentation of the affected tissues. It is autosomal-recessive inherited in men with a frequency of 1-9/1,000,000. While it is clear that pigment deposits lead to joint destruction, renal stone formation and cardiac valvulopathy respectively, the significance of ocular findings is still unclear. We therefore aim to evaluate the frequency and clinical significance of ocular findings in ochronosis and discuss possible therapeutic options...

We present an automated algorithm for the detection of blood vessels in 2-D choroidal scan images followed by a measurement of the area of the vessels. The objective is to identify vessel parameters in the choroidal stroma that are affected by various abnormalities. The algorithm is divided into five stages. In the first stage, the image is denoised to remove sensor noise and facilitate further processing. In the second stage, the image is segmented in order to find the region of interest. In the third stage, three different contour detection methods are applied to address different challenges in vessel contour...

Andrew Tanchyk, Amy Tanchyk
Nitrous oxide is absolutely contraindicated after vitreoretinal surgery that uses intraocular gas, as the mixture of gas and nitrous oxide can cause catastrophic vision loss. Professional awareness and communication are vital to prevent this iatrogenic complication. This case report identifies a side effect of vitreoretinal surgery with a benign outcome--specifically, a referred pain or pressure from left eye surgery or an associated gas bubble to the upper left quadrant. Such cases underscore the need for a dentist and staff to inquire about all ocular procedures to avoid patient vision loss due to nitrous oxide...

Eva Platner, Mati Bakon, Ruth Huna-Baron
Carotid-cavernous fistulas (CCFs) are abnormal arteriovenous communications in the cavernous sinus. In many cases of CCF's the primary signs are ocular manifestations, which include: pulsatile proptosis, orbital bruit, chemosis and conjunctival injection, elevated intraocular pressure, venous stasis retinopathy, and cranial nerve pareses. Patients in whom the fistula causes arterial drainage into the cerebral veins and sinuses are at risk for intracranial hemorrhage. The most common treatment for CCF's is endovascular occlusion of the lesion...

A 34-year-old ankylosing spondylitis (AS) patient on etanercept for 30 months presented to neurologists with paresthesia of his hands and feet. Magnetic resonance imaging (MRI) scans showed multifocal hyperintense lesions. Symptoms did not improve on stopping the anti-tumor necrosis factor (TNF) agent. Few cases of demyelinating disease occurring after more than 2 years of treatment with anti-TNF agents have been reported in patients with AS. Opthalmologists, internists, neurologists, and rheumatologists need to be aware of these adverse events, as patients may present to any of these specialties many years after treatment...

Metastatic eyelid tumours are rare and account for less than 2% of all eyelid neoplasms. We report a case of metastatic breast carcinoma to the eyelid in a 60-year-old Chinese lady presenting with a 2-year history of enlarging, painless nodular lower eyelid swelling. The 1 cm diameter lesion was provisionally diagnosed as a sebaceous cyst. However the excision biopsy revealed a mucinous carcinoma expressing oestrogen receptor protein. She had a past history of mastectomy one year previously and histology showed an infiltrating ductal carcinoma (oestrogen receptor status negative) without evidence of axillary lymph node metastasis...

Otolaryngology and ophthalmology have a long and congenial professional relationship in the development of their mutual specialties over many years. In the early years they were one professional society, but later split into their separate specialties. Some problems involve both specialties because of the shared common anatomic areas. These problems include: orbital complications of sinusitis, management of exopthalmus, silent sinus syndrome, lacrimal apparatus problems, tumor and trauma problems, optic nerve decompression, and complications of endoscopic sinus surgery...
