Diagnosis of complicated FEVR preoperatively and intra−/post-operatively: characteristics and risk factors for diagnostic timing

Table 3 The reasons of missed diagnosis of FEVR preoperatively

Reasons of missed diagnosis of FEVR preoperatively	Cases (n = 28)^a
Age<3 years, unilateral leukocoria with invisible fundus + contralateral fundus seemingly normal	8
Age ≥ 3 years, without ultra-wide-field scanning laser ophthalmoscopy at initial clinic visit or preoperatively	9
Bilateral vitreoretinal surgery or peripheral retinal photocoagulation in other hospital before the first clinic visit	2
Unilateral VH + contralateral phthisis bulbi	2
Unilateral VH + contralateral ERM	1
Unilateral RD + contralateral ERM	1
Unilateral ERM	1
Bilateral pathological myopia + myopic foveoschisis + lamellar macular hole	1
3 years < age <4 years, poor cooperation, ultra-wide-field scanning laser ophthalmoscopy failed to capture the peripheral retina	1
Premature birth history	1
Ocular trauma	1

^aThe number of cases in Table 3 is totally 28, which is more than the number of FEVR patients diagnosed intra−/post-operatively (n = 25). Because some patients had multiple reasons of missed diagnosis of FEVR preoperatively
