to evaluate the effects of refractive surgery on retinal function, in patients affeted by tapetoretinal degenerations and if this procedure could be safe for these affections.
10 patients (6 male and 4 female) for 20 eyes, mean age 31,44 +/-12,71 with mean refractive error of -8.38 D (range from -4 to-13D) undergone to refractive surgery (4 eyes PRK, 16 eyes LASEK) in the period 1999-2003. Pattern of inheritance was for 2 patients ARRP, for 3 patients xLRP, for 5 patients ARRP. Each patients before the surgery underwent to complete retinal examination (BCVA, Visual field, Full filed ERG and Microperimetry) and refractive surgery screening (topography, corneal analisys, pupillometry, pachimetry). Patients were followed at day 2-7-30-180-360 after the surgery and yearly regarding retinal examinations.
All patients showed a, better than before, best corrected and uncorrected visual acuity, moreover a statistically significative increase (p=0.034) of mean retinal sensitivity, no change was shown for ERG max amplitude. after one year of follow up 17 eyes (85%) presented a residual refractive error <0.50 D and all of them <1D. No retinal or other ocular complication was detected during the follow-up.
All patients were safely treated with refractive surgery without any significant complication, all patients showed an improvement of retinal psychophysical tests thus resembling a better retinal performance in our opinion dued to the lack of interference of spectacles or contact lenses. We have chosen a surface treatment instead of LASIK procedure because this potentially may cause corneal ectasia.
