to study the growth pattern of choroidal neovascular membranes(CNVM) secondary to Central serous Chorioretinopathy(CSC) with Spectral-domain OCT and its correlation with Flurescein angiography.
All patients were evaluated in terms of Visual Acuity , Spectral-domain OCt and Fundus fluorescein angiography.
The study included 5 eyes with newly diagnosed CNVM secondary to CSC who underwent Fluorescein angiography and SD-OCt with optovue instrument with axial resolution of 4.5-5 micrometre and transverse resolution of 10-15 micromtre. Multiple profies like radial lines, raster, 3D en-face modes were used to study the growth pattern.
A highly reflective sub-retinal and/or Sub-retinal Epithelial lesion(RPE)was localised in all eyes by SD-OCT corresponding to FA. A predominantly sub-retinal growth pattern was noted in 3 eyes while a combined sub-retinal and sub-RPE growth pattern was noted in other 2 eyes. A significant difference was noted in growth pattern when classic CNVM was compared with Occult CNVM. Classic lesions had predominantly sub-retinal growth pattern (Type 2), whereas occult lesion had a variable growth pattern.
SD-OCT is a promising potential alternative modality to visualise CNVM secondary to CSC. Angiographic lesion size and type correlated with growth pattern and size of CNVM on SD-OCT.
