During the procedure of fluorescein angiography (FA), fluorescein sodium, a natural dye substance, is injected intravenously in order to analyze the retinal vascular circulation in the posterior pole and periphery [6].
Tubercular SLC can be clinically differentiated from SC by the frequent presence of vitritis and multifocal choroiditis lesions in posterior pole and periphery, often sparing the juxtapapillary region [3].
With the consistent lordotic angle and maximal contact of the cage-bone interface, the peak stress of the DPC was mapped on the whole contact area of the endplate, the SLC on the periphery of posterior interface, and the TPC on the central edge of posterior interface.
The color fundus and autofluorescence images (A-B) evidence multiple coalescent atrophic lesions affecting the posterior pole and the periphery of the retina.
Fundus examination revealed widespread and scattered areas of depigmentation, and both fine and course clumping of the pigment epithelium located throughout the posterior pole and the periphery in both eyes without active disease were noted by 4 weeks.
These four landmarks were placed in the two volumes as follows, for each facet joint: one each in the most cranial point, the most caudal point, the most anterior point, and a posterior point in the periphery.
Fundus examination showed bilateral, multiple, deep, yellowish lesions in the posterior pole and mid-periphery.
In all patients fundus examination showed the presence of intraretinal bright yellowish white crystals disseminated in the posterior pole and mid-periphery (figure 2A, G); other retinal findings included bone spicule pigmentation, retinal vascular attenuation and diffuse choriocapillaris atrophy.
The schisis in the left eye extended from the periphery to the posterior macular region in left eye.
Congenital retinal fold (ablatio falciformis congenita) refers to a congenital malformation that is characterized by the presence of a raised retinal fold extending radially from the posterior pole to the fundus periphery.
