Lensectomy-vitrectomy for stage V cicatricial retrolental fibroplasia.
Ten infants (18 eyes) blind from stage V cicatricial retrolental fibroplasia were examined from January 1978 to January 1981 at North Carolina Memorial Hospital. The early perinatal factors which may have predisposed to the binding end-stage cicatrix are identified. To increase their visual potential and to prevent secondary angle closure glaucoma, 12 lensectomy-vitrectomies were performed on 12 eyes (eight infants). One eye (one infant) had a pars plana vitrectomy without lensectomy. Seven eyes (seven infants) were not operated. Five of these eyes (five infants) had stage VRLF while two eyes (two infants) remained stable at stage II RLF. All retinas remained detached immediately after surgery. Secondary vitrectomies with air injections (three eyes, two infants) similarly failed to attach any retinas. Adherence of ciliary epithelium to clear lens and retrolental membrane as visualized within the dilated pupil (Eifrig-Merritt sign) was an intra-operative indicator of imminent surgical failure. Two eyes (two infants) developed early vitreous hemorrhages, hyphemas, secondary glaucoma, and phthisis bulbi within 12 months. Follow-up data were unavailable on two infants. Blindness secondary to cicatricial retrolental fibroplasia is increasing due to increased survival of low birthweight premature infants. Since surgical visual rehabilitation is not possible after the retrolental cicatrix has formed, the risk factors common to this high risk population should prompt preventive therapies.
