Clinical Atlas of Peripheral Retinal Disorders by Keith M. Zinn

By Keith M. Zinn

A entire realizing of illnesses of the peripheral retina is vital to the overall ophthalmologist in addition to to the vitreoretinal health care provider. services in in­ direct ophthalmoscopy, scleral melancholy, and phone lens biomicroscopy serves as a foundation for watching the peripheral retina. those observations are then re­ corded on fundus drawing paper and the Tolentino vitreo-retinal chart. This or­ derly series of abilities permits the ophthalmic general practitioner to objectively diagnose and review particular peripheral retinal problems and plan for his or her healing administration. The scientific Atlas of Peripheral Retinal problems is a compilation of fundus paint­ ings by way of David A. Tilden in line with our observations of a big variety of sufferers over the last 15 years. The atlas is geared up alongside sensible and anatomical strains. After a short advent to the medical anatomy of the peripheral retina, the looks of the fundus as a functionality of pores and skin colour and getting older is gifted. a number of the ailments of the peripheral retina should be divided into trophic (nutritional), tractional, and a mixture of trophic plus tractional etiologies. This classifica­ tion procedure, even though a little bit simplistic, seems to be sufficient for our current point of realizing of the pathogenetic mechanisms of those problems. Un­ doubtedly, as soon as the molecular biology of those stipulations is elucidated via destiny examine, the class could be revised. additionally, there are different con­ ditions that have an effect on the peripheral retina that don't healthy the proposed category approach and are lined below separate headings, i. e.

Sample text

The cystic spaces coalesce to form a labyrinth of tunnels separated by pillars of Muller (glial) cells. On occasion, the inner walls may rupture, giving way to retinal excavations that are unrelated to vitreous base excavations. This cystoid excavation can be mistaken for a retinal hole, but it is usually not a complete hole because there is still some intact retinal tissue at its base-. Retinal detachments rarely occur around these pseudoretinal holes. The remaining Muller cells are responsible for the stippled appearance of the inner retinal surface in typical cystoid degeneration.

Zonular traction tufts are larger and longer than the cystic and noncystic retinal tufts, and, in contrast to these other tufts, retinal breaks may occur at the base of the tuft. The incidence of zonular traction tufts is 16 %, and is bilateral in 11 % of cases. About 66 % of affected eyes have one zonular traction tuft per eye, and the remaining 34 % of cases have multiple tufts per eye. Zonular traction tufts have a predilection for the inferonasal quadrant. Ora Serrata Pearls Ora serrata pearls are pinpoint-sized, round, glistening, yellow-white, sometimes calcified structures located on dentate processes, the pars plana, or on peripheral retina near the ora serrata region.

There is a predilection for the inferotemporal quadrant. In some individuals, reticular cystoid degeneration may be the precursor lesion of reticular degenerative retinoschisis. Acquired Typical Degenerative Retinoschisis Typical degenerative retinoschisis consists of a split in the neurosensory retina, usually at the outer plexiform layer, that is greater than one disc diameter in area. Characteristically, there is tissue loss in the middle layers of the neurosensory retina with disruption of Muller cells (radial pillars), resulting in a round or oval lesion in which the inner portion of the retina is elevated and has a smooth dome-shaped appearance.
