Parapapillary drusen of the retinal pigment epithelium

Acta Ophthalmologica, 2023
AbstractPurposeTo describe the occurrence, morphology and associations of parapapillary drusen of the retinal pigment epithelium (RPE‐drusen).MethodsUsing light microscopy, we histomorphometrically examined enucleated human eyes.ResultsThe study included 83 eyes (axial length: 25.9 ± 3.2 mm; range: 20.0–35.0 mm). Eyes with parapapillary RPE‐drusen (n =

Drusen of the Optic Disk in Retinitis Pigmentosa

American Journal of Ophthalmology, 1987
To clarify the nature of mulberry-like excresences of the optic disk, we histopathologically studied the eye of a 66-year-old woman with retinitis pigmentosa. Examination showed that the optic nerve excresences were ordinary drusen and not hamartomas. There was a marked predisposition to mineralization of other intraocular structures.

DISAPPEARANCE OF DRUSEN AFTER RHEGMATOGENOUS RETINAL DETACHMENT

RETINAL Cases & Brief Reports, 2010
To describe the disappearance of drusen after rhegmatogenous retinal detachment.Descriptive case report.A 72-year-old man with confluent subfoveal drusen developed a rhegmatogenous retinal detachment and subsequently improved in vision with disappearance of the subfoveal drusen less than 1 month after repair.Rhegmatogenous retinal detachment can result

Drusen of the Optic Nerve Associated With Retinitis Pigmentosa

Archives of Ophthalmology, 1985
Globular excrescences of the optic nerve associated with retinitis pigmentosa have been interpreted as drusen or as astrocytic hamartomas. The histopathologic and ultrastructural findings of globular excrescences of the peripapillary region of the optic nerve associated with retinitis pigmentosa were described in a 22-year-old patient who died in a car

New developments in retinal drusen

Ophthalmic and Physiological Optics, 1998
Summary Retinal drusen are an important manifestation of age‐related maculopathy, and increase with ageing. Recent studies have shown that gentle laser photocoagulation can lead to resolution of soft drusen and may lessen the high risk of development of choroidal neovascularisation in these cases.

Classification of retinal pigment epithelial detachments associated with drusen

Graefe's Archive for Clinical and Experimental Ophthalmology, 1992
To understand the natural history of retinal pigment epithelial (RPE) detachments (PEDs) associated with drusen, we retrospectively reviewed 125 PEDs that had not undergone laser treatment over an average follow-up period of 28 months. We identified six types of RPE detachments: pseudo-vitelliform, confluent drusen, serous, vascular, and hemorrhagic ...

Retinal Drusen and Colour Vision

1984
For drusen situated outside of retina, alteration of π1 and π3 mechanisms gives the evidence that a latent pathologic process is ready to destroy the macular area.

A fuzzy logic approach to drusen detection in retinal angiographic images

Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002
Drusen are yellow deposits at the level of the retinal pigment and are frequently associated with age-related macular degeneration (ARMD). Drusen often change in size, number and degree of confluence. A quantitative method to measure the development of drusen is needed for controlled studies of the natural history, prognosis, and tertenant of ARMD.

Bilateral Central Retinal Artery Occlusions, Disk Drusen, and Migraine

American Journal of Ophthalmology, 1989
A central retinal artery occlusion occurred in the left eye of a 25-year-old woman with migraine and bilateral intrapapillary drusen. An extensive investigation failed to establish the presence of any systemic disease or vasculopathy. Eight years later she had a central retinal artery occlusion in her right eye.
