Progression of binocular vision following cataract surgery

Amaç: Katarakt cerrahisi sonrası erken postoperatif dönemde, hastalarda binoküler görmenin progresyonunu araştırmak. Yöntem ve gereç: 84 katarakt hastası, fakoemülsifikasyon ve arka kamara monofokal göziçi lens implantasyonu sonrası 1. ve 3. ayda değerlendirildiler. Binoküler görmenin derecelendirilmesinde sinoptofor kullanıldı. Steroskopik görme keskinliği Titmus Stereotest ile ölçüldü.Bulgular: Postoperatif 3. aydaki değerlendirmede 1. aya göre, hastalarda önemli derecede daha fazla oranda stereopsis (P = 0.004), ve daha iyi seviyede stereo keskinlik (P < 0.001) saptandı. Ayrıca postoperatif 3. aydaki görme keskinliğindeki artış (P = 0.001) ve anizometropi miktarındaki azalma (P = 0.023) istatistiki olarak anlamlıydı. İstatistiksel olarak stereo keskinlik düzeyi ile görme keskinliği, iki göz arasındaki görme keskinliği farkı, anizometropi miktarı, yaş arasında korelasyon tespit edilmedi (P > 0.05). Füzyonu mevcut olmayan hastalardaki supresyon, görme derecesi iyi olan ve hatta diğer göze göre daha iyi görme derecesine sahip olan, opere gözlerde tespit edildi.Sonuç: Katarakt cerrahisi sonrası erken postoperatif dönemde, hastalarda binoküler görmede gelişme tespit edildi ve bu gelişmenin optik faktörler dışında, nöral faktörlerle de ilişkili olabileceği düşünüldü.

Katarakt cerrahisi sonrasi binoküler görmenin progresyonu

Aim: To investigate the progression of binocular vision of patients after cataract surgery in the early postoperative period.Materials and methods: Eighty four cataract patients were evaluated at postoperative 1 and 3 months after phacoemulsification and posterior chamber monofocal lens implantation. For the evaluation of the grades of binocular vision, synoptophore was used. Stereoscopic acuity was measured with the Titmus Stereotest.Results: Evaluation at postoperative 3 months was associated with a significantly higher proportion of patients with stereopsis (P = 0.004), better levels of stereoacuities (P < 0.001) than the evaluation at postoperative 1 month. Significantly higher visual acuities (P = 0.001) and lower interocular difference in refraction values (P = 0.023) were also noted at postoperative 3 months. The level of stereoscopic acuity was not significantly correlated with the level of visual acuity, interocular visual acuity difference, interocular difference in refraction, and the age of patients (P > 0.05). In patients without fusion, suppression was found in the operated eyes with favorable visual acuities, and even in some of those with higher visual acuities compared to the fellow eye.Conclusion: During the early postoperative period of cataract patients, improvements in binocular vision were observed, which may be attributed to neural factors along with optical factors because of the cerebral basis for binocular vision.
