Abstract

Purpose : To study optical coherence tomography angiography findings in patients with serous detachments secondary to posterior staphyloma and tilted disk syndrome.

Methods : Nine eyes with posterior staphyloma or tilted disk syndrome and a serous macular detachment were studied. All patients had multimodel imaging, including color fundus photos, fluorescein angiography, indocyanine green angiography and spectral domain OCT (SD-OCT) done. The Canon OCT-A (Angio Expert AX module OCT HS100, Canon, Japan) and Spectralis OCT-A (Heidelberg Engineering, Heidelberg, Germany V 6.9A) were used to study retinal and choroidal vascular changes. A choroidal neovasculirization was excluded in all patients.

Results : All patients showed a thicker subfoveal choroidal thickness as was to be expected for their age and degree of myopia. An abrupt and focal change in choroidal thickness was also present in all cases. This focal change of choroidal thickness was located within the edges of the serous detachment. OCT-A results for the superficial and deep vascular plexus, as well as the outer retina and choriocappillaris were difficult to interpretate because of acquisition difficulties. There appeared to be a difference in flow in thicker choroids in comparison to areas with thinner choroids. The flow difference seemed attributable to reduced flow in the choriocappillaris overlying thinner parts of the choroid. En face imaging showed pachyvessels at the edge of subretinal fluid, usually at the top of the staphyloma. Canon OCT-A was faster than Spectralis OCT-A and experienced less acquisition difficulties. Also, manual segmentation was easier using the Canon OCT-A software. Imaging acquired with Spectralis OCT-A showed more details.

Conclusions : The definite cause of a serous detachment is cases with staphyloma induced serous maculopathies could not be determent with OCT-A, however the reduced flow in parts of the choroicappillaris and choroidal pachyvessles at the border of the subretinal fluid may play a causative role in the pathogenesis of subretinal fluid in cases with posterior staphyloma and tilted disk syndrome. This study experienced acquisition difficulties.
