Distinguishing between a cerebrospinal fluid (CSF) collection of the upper eyelid and an abscess can be challenging, as the following case demonstrates. Each may be preceded by surgical intervention and both could present with pyrexia. Good clinical skills will assist in differentiation, but laboratory tests are required to provide the ...

Importance  Retinal detachment with avascularity of the peripheral retina, typically associated with familial exudative vitreoretinopathy (FEVR), can result from mutations in KIF11, a gene recently identified to cause microcephaly, lymphedema, and chorioretinal dysplasia (MLCRD) as well as chorioretinal dysplasia, microcephaly, and mental retardation (CDMMR). Ophthalmologists should ...

Endophthalmitis prophylaxis for elective cataract surgery is a subject of considerable debate. The use of perioperative povidone-iodine and an eyelid speculum and drape with isolation of eyelids and eyelashes as well as meticulous sterile preparation and procedures are effective in limiting the incidence of endophthalmitis after cataract surgery.1 The rapid ...

Graphic Jump LocationA healthy man in his late 30s experienced sudden visual loss and presented with an extremely rare combination of branch retinal artery (black arrowhead) and vein (white arrowhead) occlusion that progressed to neovascular glaucoma. Blood workup revealed hyperhomocysteinemia (homocysteine level, 52 μmol/L [to convert to milligrams per liter, ...

Lymphoid tumors of the conjunctiva, also referred to clinically as salmon patches, have a favorable prognosis.1,2 They are composed of reactive lymphoid hyperplasias and low-grade lymphomas. To our knowledge, associated intralymphatic lymphocytostasis has received no attention in the ophthalmic literature, and we describe it herein.

Stromal disease (ectasia, opacities, scars, or melting) that occurs after penetrating keratoplasty (PK) can variously affect visual outcome.1,2 To date, even in the presence of healthy endothelium, this type of complication has been treated with subsequent PK.3 Instead, the selective replacement of the diseased stroma by means of deep anterior ...
Optogenetics is a technology that uses gene therapy to induce the expression of light-activated ion channels in cells, which renders the cells light-sensitive. When these cells are illuminated with light of the proper wavelength, membrane depolarization (or hyperpolarization) is induced by the light-sensitive ion channels, and if the cells are ...

Scleritis is an uncommon manifestation of sarcoidosis. Initial treatment for most patients is systemic corticosteroids, although immunomodulatory therapy is necessary in some patients. Biological response modifiers such as tumor necrosis factor (TNF) antagonists may be useful in patients with scleritis refractory to immunomodulatory therapy.1 Patients who fail therapy with TNF ...
