Confocal Scan Features of Keratic Precipitates in Granulomatous versus Nongranulomatous Uveitis

چکیده
PURPOSE To compare the morphologic features of keratic precipitates (KPs) by confocal microscopy in granulomatous versus nongranulomatous noninfectious uveitis. METHODS KP morphology was determined by confocal scan in patients with noninfectious granulomatous and noninfectious nongranulomatous uveitic cases. RESULTS One hundred and twenty-seven eyes of 90 subjects with noninfectious uveitis were studied. Thirty-nine eyes had granulomatous and 88 had nongranulomatous uveitis. Smooth-rounded KPs were significantly more common in the granulomatous subgroup (P<0.001) while cruciform and dendritiform KPs were more frequent in nongranulomatous uveitis (P<0.001 and P<0.005 respectively). CONCLUSION Confocal scan may be used as an adjunctive tool for differentiating granulomatous from nongranulomatous uveitis. Smooth-rounded KPs are strongly suggestive of granulomatous inflammation.

In vivo Confocal Microscopy in Differentiating Ipilimumab-Induced Anterior Uveitis from Metastatic Uveal Melanoma
This report aims to describe the facilitating role of in vivo confocal microscopy in differentiating inflammatory cells from a metastatic process in a patient with uveal melanoma and multiple systemic metastases who developed anterior uveitis while under ipilimumab treatment. A 43-year-old woman developed systemic metastases 11 months after treatment of amelanotic choroidal melanoma in her righ...

PURPOSE Involvement of the cornea endothelium during uveitis has not been extensively studied even though it might participate in or constitute a target of ocular inflammation. Formation of keratic precipitates (KP) is a characteristic finding in several forms of uveitis. The aim of this prospective study was to examine the vicinity of keratic precipitates in infectious and noninfectious uveiti...

INTRODUCTION Usher syndrome is a genetically heterogeneous condition and represents the most common cause of inherited combined vision and hearing loss. Deficits manifest as sensorineural hearing loss that typically develops at a young age and retinitis pigmentosa that can lead to peripheral vision loss and night blindness. As a result, this syndrome can have a significant impact on a patient's...

A 34-year-old female with Usher syndrome, but no family history of similar illness, presented with complaints of vision reduction, redness, and photophobia. Biomicroscopic examination showed mildly injected conjunctivae bilateral, small, round keratic precipitates; bilateral +2 cells with no flare reaction in the anterior chamber; and bilateral posterior subcapsular cataracts. No associated pos...
