入选标准
- •patients with spherical ≥ -8 diopters or axial length ≥ 26.5mm.
- •The foveoshisis combined with foveal detachment was showed on the OCT image. The foveal detachment height≥ 250 um ,and the thickness of sensory retina of foveal detachment was ≤100 um;
- •patients signed the ICF.
- •patients with BCVA ≤0.5,and with visual disturbance symptoms.
排除标准
- •patients with macular hole
- •accompanied or secondary of other fundus disease
- •received vitrectomy due to other diseases
- •glaucoma cannot be controled by medication
- •patients with other retinal or choroidal disease that may affect VA
- •poor patients compliance
- •poor condition that cannot undertake the surgery
- •optical opacities which make it difficult to exam fundus or measure on OCT
