Alan D Proia
A 12-month-old boy developed periocular necrotizing fasciitis with swelling of both eyes and redness and a discharge from the left eye approximately 36 hours after blunt trauma. Computed tomography revealed pre-septal and soft tissue edema on the left side, but no signs of orbital involvement, orbital fractures, or drainable abscess in the anterior left lower eyelid. The inflammatory signs worsened over the next day, and there was purulent discharge from the left lower eyelid and an abscess and necrosis of the lower eyelid skin...

Hyewon Chung, Suk Ho Byeon
Various important findings related to the development and progression of idiopathic macular holes (MHs) have been described using optical coherence tomography (OCT) since Gass first described the stages of MH development using biomicroscopy in 1988 and 1995. We believe that a system for classifying and staging MHs should reflect the degree of disease status and its progression and have value not only from a practical point of view (by predicting the chance of closure or visual recovery) but also provides researchers and clinicians with insights into the pathogenesis and disease progression of MH...

Siddarth Rathi, Nathan M Radcliffe
Cataract and glaucoma are the leading causes of blindness worldwide and commonly coexist in elderly patients. Endocyclophotocoagulation (ECP) is a minimally invasive approach for glaucoma management that is amenable to combination with cataract surgery. We review the literature on ECP and evaluate intraocular pressure reduction efficacy when combined with phacoemulsification. Several studies demonstrate that phacoemulsification and ECP (PECP) successfully reduces intraocular pressure (IOP) and decreases medication burden...

Hilal Nalci, Kaan Gündüz, Esra Erden
Orbital cellulitis associated with retinoblastoma is uncommon and is characterised by non-infectious inflammation of the periorbital structures. The underlying mechanism is thought to be necrosis of the intraocular tumor leading to intraocular and periorbital inflammation. We report two retinoblastoma patients who presented with an orbital cellulitis-like picture. and discuss clinical characteristics, histopathologic features, and treatment.

Stem cells are capable of giving rise to progenies with specific functional and morphological traits and, in recent years, extraordinary scientific advances have initiated an era of hope for clinical regenerative strategies and tissue engineering applications. We appraise the potential benefits of human umbilical cord derived stem cell therapy and consider current approaches to utilize these stem cells in corneal epithelial, stromal, and endothelial disorders.

A 32-year-old woman presented with the acute onset of a small scotoma in the right visual field. She was initially thought to have optic neuritis, but brain magnetic resonance imaging was normal. A review of her symptoms and medications disclosed recent use of oral contraceptives. Near-infrared imaging was the only objective abnormality, consistent with her Amsler grid changes, leading to the diagnosis of acute macular neuroretinopathy.

Retinal angiomatous proliferation (RAP) is a unique variant of neovascular age-related macular degeneration. Published studies have estimated that up to 15% of patients with neovascular age-related macular degeneration have RAP. Clinical features frequently associated with RAP include bilateral disease, presence of pigment epithelial detachments, and reticular pseudodrusen. RAP is more frequently associated with the development of retinal pigment epithelial tears and geographic atrophy that can lead to severe vision loss...

REVIEW
M Reza Razeghinejad, Shane J Havens, L Jay Katz
Trabeculectomy with antimetabolites is the most commonly performed surgery worldwide for glaucoma patients with progressive optic nerve head injury and visual field loss despite maximum pharmacologic intraocular pressure (IOP) lowering therapy. Trabeculectomy bleb-associated infections (BAI) remain one of the most feared early and long-term complications of trabeculectomy surgery because of their poor prognosis and variable response to antimicrobial therapy. Several studies have evaluated how surgical technique, conjunctival incision location, comorbid ocular pathology, concurrent medication use, and bleb morphology affect the risk of BAI...

A 19-year-old man noticed blurred vision in his right eye. He had an intraocular pressure of 60 versus 12 mmHg in the fellow eye. He was initially diagnosed with an atypical, advanced pigmentary glaucoma. The intraocular pressure did not respond to maximal medication, deep sclerectomy, goniopuncture, and 2 cyclophotocoagulations. Sixteen months after presentation, malignancy was first suspected, and the eye was enucleated. A ring melanoma of the anterior chamber angle was confirmed by the histopathologic examination...

The cavernous venous malformation of the orbit, previously called cavernous hemangioma, is the most common primary orbital lesion of adults. Cavernous venous malformation occurs more often in women and typically presents in the fourth and fifth decades of life. It is a benign vascular malformation characterized by a well-defined capsule and numerous large vascular channels. The most common sign of cavernous venous malformation is progressive axial proptosis from the preferential involvement of the intraconal orbital space...

Pituitary adenoma invasion into the orbit is a rare phenomenon with only 22 cases, including the present case, in the literature. Our case is a 31-year-old man who presented with biopsy-proven atypical pituitary adenoma invading the right orbit after a prior resection. We compare his clinical course with previous cases.and discuss clinical features, radiological features, management considerations, histologic features, and prognosis. Cases are organized by specific pituitary tumor type to aid in determining appropriate management...

We report a patient with left eye positional transient visual obscurations, diplopia, a left afferent pupillary defect, and optic disk edema-all occurring during pregnancy. Noncontrast magnetic resonance imaging revealed an orbital mass encasing the optic nerve and extending through the superior orbital fissure into the cavernous sinus. An magnetic resonance imaging with gadolinium after parturition and strongly positive somatostatin receptor scintigraphy suggested the diagnosis of meningioma. Biopsy confirmed the diagnosis, and she was treated with CyberKnife stereotactic radiosurgery...

An apprenticeship model has traditionally been used in procedural and surgical teaching. As the pressures of work hours and patient outcome monitoring increase, surgical teachers need a more flexible plan for teaching procedural skills. We attempt to delineate a program of preprocedural, intraprocedural, and postprocedural teaching that can be used in the field of ophthalmology to maximize a resident's skill acquisition in a constructive learning environment. We review the literature on surgical teaching from within ophthalmology as well as other surgical fields and combine this with teaching experience in an ophthalmic surgical training program to produce a collection of procedural teaching guidelines...

Imaging devices such as the Heidelberg retinal tomograph-3 (HRT3), scanning laser polarimetry (GDx), and optical coherence tomography (OCT) play an important role in glaucoma diagnosis. A systematic search for evidence-based data was performed for prospective studies evaluating the diagnostic accuracy of HRT3, GDx, and OCT. The diagnostic odds ratio (DOR) was calculated. To compare the accuracy among instruments and parameters, a meta-analysis considering the hierarchical summary receiver-operating characteristic model was performed...

Intraocular inflammatory tumefactions large enough to simulate neoplasms are uncommon. We report a patient with a large intraocular inflammatory mass composed of cells with features of histiocytes and myofibroblasts that was associated with lens-induced uveitis. The spindle cell mass appears to have arisen as an exaggerated response to exposed lens fibers. Although information from immunohistochemistry and cytogenetics has advanced the classification of inflammatory tumefactions, this case highlights the challenges in establishing the nature of these lesions...

Advances in the understanding of the genetic, molecular and cellular biology of retinal diseases have led to the development of new treatments. These expanding treatment options demand appropriate outcome measures for studies of treatment benefit including patient-reported outcomes (PRO). A plethora of PRO instruments assess impacts of retinal diseases from the patients' perspectives. We review all of the studies that implemented PRO assessment in retinal diseases and also discuss quality assessment of the PRO instruments...

We compare outcomes following radiotherapeutic and surgical management of iris melanoma. End points included local tumor recurrence, metastases, and common complications. From an initial search that yielded 231 articles, we found 17 relevant studies with 761 eyes. The gender distribution was balanced with a mean age of 52 years. Most studies focused on either proton beam (49.4%) or plaque (31.4%) radiotherapy. Rates of local recurrence (range: 0%-8%) and metastatic development (0%-5%) were favorable following radiotherapy; however, common complications included cataract (36%-73%), glaucoma (3%-92%), and corneal conditions (0%-33%)...
