Aim: Aim of this study is to evaluate retrospectively functional results of cryosurgical treatment of uncomplicated, idiopathic rhegmatogenous retinal detachment including macula region in phakic patients operated on at the Department of Ophthalmology, Faculty Hospital, Palack˘ University, Olomouc, Czech Republic, E.U., during the period 2002 –2013, and to evaluate the significance of the macula detachment duration for the final visual acuity.
Methods: In the study group were included 56 eyes of 56 patients operated in the years 2003 – 2012 at the Department of Ophthalmology, Faculty Hospital, Palack˘ University, Olomouc. All patients were phakic and in all of them, the retinal detachment including the macula region was diagnosed. The mean follow-up period of the patients was 8,75 months. The initial and final visual acuity testing were performed. Comparing the initial and final visual acuity we rated the level of the visual acuity change. The result was stated as improved, if the visual acuity improved by 1 or more lines on the ETDRS chart. The result was rated as stabilized, if the visual acuity remained the same or it changed by 1 line of the ETDRS chart only. The result was evaluated as worsened, if the visual acuity decreased by 1 or more lines of the ETDRS chart. In the followed-up group, the authors compared visual acuity levels in patients with the macula detachment duration ≤ 10 days and ≥ 11 days. For the statistical evaluation of achieved results, the Mann – Whitney U test was used.
Results: The visual acuity improved in 49 (87 %), did not changed in 5 (9 %) and worsened in 2 (4 %) patients. The patients with macula detachment duration ≤ 10 days achieved statistically significant better visual acuity than patients with macula detachment duration ≥ 11 days. Conclusion: Patients with macula detachment duration ≤ 10 days have better prognosis for functional result than patients with macula detachment duration ≥ 11 days.
