Idiopathic multiple serous detachments of the retinal pigment epithelium: a report of two cases.

A relatively uncommon entity is described which is characterized by idiopathic serous detachments of the retinal pigment epithelium (RPE). In contrast to RPE detachments associated with the spectrum of age-related macular degeneration and other choroidal diseases, the visual prognosis in this entity is usually good. In some respects, idiopathic serous RPE detachments display characteristics similar to idiopathic central serous chorioretinopathy and could be a variant thereof. The differential diagnosis also includes multifocal Best's vitelliform dystrophy.

Iris microhemangiomas.

Iris microhemangiomas (IM) are benign proliferations of small, twisted blood vessels along the pupillary margin. They are usually bilateral and appear to be developmental in nature. IMs most commonly occur in patients with myotonic dystrophy and adult-onset diabetes mellitus, but have also been associated with respiratory disease, congential heart disease, and central retinal vein occlusion. Additionally, they may be found in individuals without obvious ocular or systemic abnormality. The etiology remains obscure. In this report, illustrative cases are followed by a brief discussion outlining typical clinical manifestations, etiological considerations, and possible implications.

The endpoint of laser speckle pattern meridional refraction.

Motion of the speckle pattern observed by an ametrope viewing laser light reflected from a rotating cylinder with a matte surface is discussed. Mathematical expressions are derived for the apparent speed and direction (angular velocity) of the pattern when spherical neutralizing lenses are put in place and conditions for an endpoint appropriate for meridional refraction are discussed.
