The authors present the diagnostic challenge of an unusual case of neurofibromatosis type 1 with unilateral congenital glaucoma, buphthalmos, and sphenoid-orbital dysplasia. The accompanying type of osseous orbital dysplasia has rarely been described in the literature, complicating the diagnostic and management process.

Conjuctivodacryocystorhinostomy with a Lester Jones bypass tube is the standard treatment in these situations. Although a high rate of anatomic success can be achieved with this procedure, a relatively high rate of complications and poor patient satisfaction have been reported. Because of this, alternative techniques have emerged. Herein, we review all these techniques described in the literature. Increasing interest in minimally invasive surgery and developments in fiberoptic technology have fueled advances in endocanalicular surgery. Canalicular trephination for obstructions at any level of the canalicular system and laser and balloon canaliculoplasty for focal canalicular and common canalicular stenoses may offer a well tolerated, fast and easy alternative, with potentially better patient satisfaction when compared with conjuctivodacryocystorhinostomy. The alternative techniques to conjuctivodacryocystorhinostomy are less invasive, and respect and utilize any healthy and functional part of the canalicular system. The correct choice of the technique for a given canalicular obstruction, and therefore the long-term success, depends on the site and degree of the obstruction.

To report the acute development of hypopyon after primary cryopreserved amniotic membrane transplantation (AMT) for persistent corneal epithelial defect and sterile ulceration. Case Presentation. A selected case report of a 71-year-old male who underwent primary cryopreserved AMT for the management of long-standing corneal epithelial defects and stroma thinning. The patient developed 2 mm sterile hypopyon within 48 hours after AMT for corneal surface reconstruction. He responded well to the intensified routine postoperative topical treatment of steroid and antibiotic eye drops with the hypopyon resolving completely one week later. Five weeks after surgery, the corneal surface was smooth and epithelialized with no anterior chamber reaction or recurrence of hypopyon. Discussion. Hypopyon may develop as a rare complication of primary cryopreserved AMT for sterile corneal defects. It may be attributed to immunologic or hypersensitivity reaction and should be differentiated from...

Factors such as variable temperature, airflow velocity, relative humidity, seasonality, and pollutants can alter the rate of tear film evaporation, improving or exacerbating symptoms of DED. Results from currently available clinical tests do not always correlate well with patient-reported symptoms, and the continually changing environment and variability in DED symptoms present challenges for the design and conduct of clinical trials. Controlled adverse environment chambers allow standardization of temperature, humidity, and airflow and may minimize potential confounding factors in clinical investigations. Their use can promote accurate study of the pathophysiology of DED, discovery of disease biomarkers, and assessment of the effect of various therapeutic approaches on patients' symptoms. Controlled ad...
Glucocorticoids (GCs) are used for Graves&#39... more Glucocorticoids (GCs) are used for Graves' ophthalmopathy (GO) in two different clinical settings: 1) moderately severe to severe eye disease; and 2) mild eye disease, for which radioiodine therapy is given to treat concomitant hyperthyroidism. Intravenous pulse corticosteroids have a small but statistically significant advantage in terms of response rate compared with oral corticosteroids and cause significantly fewer adverse events. Steroids should be used for as short a period of time as possible. The need for large doses of steroid over a long period of time is a hint that other treatment modalities need to be explored. Combination treatment with oral steroids and ciclosporin, another immunosuppressant, are more efficacious than use of either agent alone. The same applies to combination treatment with oral steroids and orbital radiotherapy. Somatostatin analogues (SM-as) have marginal clinical efficacy and are expensive. More potent analogues, like SOM230, could prove to be the treatment of choice in moderately severe cases of GO. The latter, in contrast to the thus far used analogues, has a rather high affinity for all SM receptors except SM receptor 4.
