SURGICAL OUTCOMES OF TRACTIONAL MACULOPATHY ASSOCIATED WITH FAMILIAL EXUDATIVE VITREORETINOPATHY IN CHILDREN.

Purpose: To evaluate the surgical outcomes of pediatric familial exudative vitreoretinopathy complicated by tractional maculopathy.

Methods: Retrospective case series. Chart review of 14 children (15 eyes) diagnosed with tractional maculopathy-complicated familial exudative vitreoretinopathy who received vitrectomy.

Results: The mean age at surgery was 7.2 years. The mean follow-up duration was 14.1 months. The logarithm of the minimum angle of resolution of best-corrected visual acuity improved from 1.0 ± 0.6 (20/200 Snellen) to 0.6 ± 0.6 (20/80 Snellen) postoperation (t = 4.293, P = 0.001). The peripapillary temporal inner angle [63.9 (15.7)° vs. 71.1 (31.2)°, z = -2.726, P = 0.006] and peripapillary temporal outer angle (63.4 ± 25.2° vs. 69.6 ± 23.5°, t = -2.820, P = 0.014) widened postoperation. Postoperative best-corrected visual acuity was superior in eyes with a shorter time between symptom onset and surgery (r = 0.688, P = 0.019), better preoperative logarithm of the minimum angle of resolution best-corrected visual acuity (r = 0.830, P < 0.001), and preoperative widening of the outer nuclear layer (r-pb = 0.730, P = 0.007) and foveal avascular zone (r-pb = 0.794, P = 0.002), and in eyes with postoperative ellipsoid (r-pb = 0.641, P = 0.018) and interdigitation zones integrity (r-pb = 0.614, P = 0.026), widening of the outer nuclear layer (r-pb = 0.816, P = 0.001) and foveal avascular zone (r-pb = 0.940, P < 0.001), and absence of the inner retinal layer at the fovea (r-pb = 0.672, P = 0.012).

Conclusion: Vitrectomy is effective for pediatric familial exudative vitreoretinopathy complicated by tractional maculopathy. Patient selection is crucial and iatrogenic complications should be avoided.
