Topikal Anestezik Damlanın Oküler Biyometri Ölçümlerine Etkisinin İncelenmesi

Amaç: Topikal anestezik kullanımının aksiyel uzunluk(AU), ortalama keratometri(KM), merkezi kornea kalınlığı (MKK), ön kamara derinliği (ÖKD), göz içi lensgüç (GİLG) değerlerine etkisinin incelenmesi.Hastalar ve Yöntem: Çalışmaya rutin göz muayenesi için polikliniğimize başvuranherhangi bir oküler veya sistemik hastalığı olmayan, sistemik veya oküler ilaç kullanmayan emetrop kişiler dahil edildi. Olguların ortalama yaşı 22,80±2,29 (18-26) yıldı.15 erkek 15 kadın, 30 kişinin 30 gözü çalışmaya dahil edildi, sağ gözler çalışma, solgözler kontrol grubu olarak kabul edildi. Çalışma grubu kendi içinde topikal anestezik(% 0.5 proparakain hidroklorür,Alcaine,Alcon) öncesi, 20 saniye sonrası ve 2 dakikasonrası değerleri olarak üçe ayrıldı. Diğer gözlere topikal anestezik damlatılmadı vebaşlangıç, 20 saniye ve 2 dakika sonrası değerler alındı. Tüm ölçümler optik biyometri (ALScan Nidek Japonya) cihazı ile yapıldı.Bulgular: Kontrol grubunda başlangıç, 20 saniye sonrası ve 2 dakika sonrası tümölçüm değerlerinde herhangi değişiklik izlenmedi.(p>0.05) Çalışma grubundaAU,ÖKD,KM ve GİLG değerlerinde hem çalışma grubunun başlangıç, 20 saniye ve2 dakika sonrası değerleri arasında hem de kontrol grubunun değerleri arasında anlamlı farklılık izlenmedi. (p>0.05) MKKde ise anestezik damladan 20 saniye sonrasıdeğerler hem damla öncesi, hem 2 dakika sonrası ve hem de kontrol grubundanistatistiksel olarak anlamlı farklı bulundu. (p

Investıgatıon of Topical Anesthetic Drop's EffectsOn Ocular Biometry Measurements

Aim: Investigation of the efffects of using topical anesthetic on axial length (AL), average keratometry (AK), central corneal thickness (CCT), anterior chamber depth (ACD), intraocular lens power (IOLP). Patient and methods: 15 female and 15 male emetrop patients , applied to our our polyclinic for routine eye examination, who don’t have any ocular or systemic disease, don’t use medication related to ocular or systemic diseases. The cases were between between 18-26 years old and avarage age was 22,80±2,29 years. 30 eyes of those 15 people were examined. The right eyes were taken as the study group while left eyes were taken as the control group. Study group (right eyes) was separated in to 3 groups with regard to time intervals of measurements as; before topical anesthetic (0.5 % proparacaine hydrochloride, Alcaine, Alcon), after 20 seconds and after 2 minutes. No anesthetic were applied to control group (left eyes) although all the measurements were made at the same time intervals. All measurements were made with optical biometry device (ALScan, Nidek, Japan). Results: There was no change in all the measurements of the control group's before drop, after 20 sec and after 2 mins (p>0.05) intervals. There wasn’t any significant difference in both study group's and control group's AL, AK, ACD and IOLP measurements between their own time intervals(p>0.05). However CCT measurements of after 20 sec were significantly higher than both before drop and after 2 minutes' intervals, as well as compared to control group's measurements (p0.05). Conclusion: In this study, we observed that anesthetic drop doesn’t have an effect on AL, AK, ACD and IOLP measurements. However we suggest taking CCT measurement which is made 20 sec after the drop into consideration just because it was significantly different from other groups, especially when examining the intraocular pressure.
