AIMS To report observations relating to the clinical recognition and possible basis of reticular pseudodrusen (RPD). METHODS This retrospective study reports the evolution of RPD in 166 patients who had follow-up of over 1 year using multiple imaging techniques. Mean age when first seen was 73.3 years and the mean period of observation was 4.9 years (range 1-18 years). Associated macular chan...

The patient, a 7-year-old boy, was first seen at the Western Ophthalmic Hospital after a school medical examination showed he had poor visual acuity. He had no previous history of any systemic or ocular illnesses. His parents and grandparents were unrelated. The best corrected visual acuity was 6/iz with +2 75 D cyl., axis I05' in the right eye and 6/9 with + Z5o D cyl. axis 800 in the left eye...

Age-related macular degeneration (AMD) is a leading cause of vision loss in patients >50 years old. The hallmark of the disease is represented by the accumulation of extracellular material between retinal pigment epithelium and the inner collagenous layer of Bruch's membrane, called drusen. Although identified almost 30 years ago, reticular pseudodrusen (RPD) have been recently recognized as a ...

We present a 32-year-old white patient with congenital reticular ichthyosiform erythroderma, also known as ichthyosis variegata. The patient had typical clinical features with areas of normal appearing skin surrounded by erythematous hyperkeratotic patches. The smaller ‘‘confetti-like’’ patches were mostly present on the trunk, while the larger areas forming a reticular pattern predominated on ...

Atypical cells have been consistently found in the palatine tonsil (PT) in patients with breast, stomach, and rectal cancer, and less often with gastric polyposis, mastopathy, and soft tissue papilloma. The vast majority of the atypical cells is represented by reticular cells, which are found in smears irrespective of the tumor stage. The number and size of PT atypical reticular cells in patien...

The reticular formation was one of the last neuroanatomical structures to be described. Even today, there is no consensus on the nervous system elements that make up this anatomical structure. Such famous anatomists as Reil, Deiters, Burdach, and Cajal, among others, have progressively contributed with new findings regarding the description of the reticular formation. Nevertheless, experiments ...

A double-labeling protocol was used to determine whether thalamocortical and reticular thalamic cells with overlapping receptive fields form open or closed loop connections in the vibrissal system of the rat. Results show that individual reticular cells exclusively project to the barreloid representing the principal whisker of their receptive field. Furthermore, solid retrograde labeling of rel...

Nodular and reticular opacities were detected in both lower lung fields of a 75-year-old man in 2000. Bronchoscopy revealed pulmonary sarcoidosis. In 2002, nodular and reticular opacities were shown in the right upper lobe, and video-assisted thoracoscopic surgery was performed. The histological findings revealed usual interstitial pneumonia (UIP)-like lesions, whereas non-caseous granulomas we...
