macula with a wide view till serrated junction between the retina and the ciliary body known as ora serrata
. The main features of the reinverting operating lens systems are that it has low profile design which minimizes the scope of the stack height.
Each sample was cut cranially to ora serrata
and fixed in 4% paraformaldehyde in 0.1 M phosphate buffered saline (PBS, pH 7.4).
Laser photocoagulation (0.3 s and 100–200 mW power) was applied from the avascular retina to the ora serrata
in all quadrants (360[degrees]) with near-confluent impacts.
In part 1 of this series (Optometry Today, April 4, 2015, p52-56) that the peripheral retina is the area extending from the equator anteriorly to the ora serrata
. The peripheral retina is best viewed on a dilated patient using binocular indirect ophthalmoscopy (potentially also with scleral depression), contact fundus lens using the trapezoid mirror, and/ or wide-field photography.
Examination of the enucleated left eye showed an 11 X 10-mm white tumor (Figure 2) arising in the area of the peripheral retina/ciliary body from the area of the ora serrata
temporally (Figure 2, upper right inset).
His first three collections of poetry are Ora serrata
retinae (1980), Natura and venatura (1987), and Esercizi di tiptologia (1992), reprinted with new poems in Poesie (1981-1992) e altre poesie (1996).
After removing the cornea, each sample was cut at the ora serrata
and fixed in 4 % neutral buffered formalin.
The rod-dense peripheral retina is the portion of the retina located anterior to the equator and extending to the ora serrata
, which is where the retina and choroid end.
Also known as cobblestone degeneration, this condition is present in about 25% of the population and appears as well defined yellow white patches between the equator and the ora serrata
. It is characterised by the absence of the outer layers of the retina, in particular the choroid, which permits an uninterrupted view of the sclera.
The far periphery extends from the equator to the ora serrata
. The width of this circular area varies, depending on ocular size and refractive error.
