We retrospectively analyzed the results of treatment of 4 patients with pigmentary retinal abiotrophy (5 eyes), the age is up to 60 years, operated on account traction macular edema on the background of epiretinal membrane. All patients underwent visometry, ehobiometry, ultrasound B-scan before and after the surgery, optical coherence tomography (OCT) of macular zone, perimetry. Pigmentary retinal abiotrophy diagnosis was confirmed by electroretinography - scotopic, rhythmic and total ERG reduction; photopic changes: within the norm – 3 eyes and its reduction – 2 eyes. All patients underwent microinvasive vitrectomy 25G with the epiretinal membrane removal.
Changes in visual acuity and retinal thickness data in the macular zone are presented in Table 1. Таble 1 Data of visual acuity, retinal thickness in the macular area Examination periods On 1m. 3m. admis. after after Visometry 0.2 0.325 0.4 OCT (microns)362 305 280 From the data presented in the Table 1 it follows that after the surgical treatment the retina thickness in the macula in all patients decreased on average by 57 microns one month after the operation and by 82 microns after 3 months. Visual acuity increased by 0.1 after 1 month and by 0.2 after 3 months. Subjectively patients also noted improvement of their central vision. Perimetry data remained without any changes within 3 months. Analysis of the surgical treatment results in the macular area diseases in patients with pigmentary retinal abiotrophy shows that surgery improves the central visual functions and for some time slows down the development of the pathological process in the central zone.
Thus, microinvasive vitrectomy 25G with the removal of epiretinal membrane can be regarded as a variant of rehabilitation treatment aimed at improving and relative stabilization of visual functions in patients with pigmentary retinal abiotrophy and pathological changes in the macular zone.
