Methods: A chart review of patients with normal tension glaucoma was retrospectively analyzed. All patients underwent a Humphrey visual field (HVF) test and logarithm of the minimal angle of resolution best-corrected visual acuity (log MAR BCVA) was measured over a 6 months period. Changes in mean deviation (MD), pattern standard deviation (PSD) of visual field and log MAR BCVA were compared among anthocyanoside, GBE and no medication (control) groups. Patients were divided according to the presence of DM. Results: A total of 406 NTG patients, including 151 DM patients, were included in the present study. MD was improved in the anthocyanoside and GBE groups, but not in the control group. PSD was not significantly different in all groups. BCVA was improved in the anthocyanoside group, but deteriorated in the control group. The results were similar in patients with or without DM. The generalized linear model demonstrated that systemic medication affected changes in visual indices. Conclusions: The results from the present study suggest that anthocyanoside and GBE may be helpful for improving visual function in some patients with NTG regardless of their DM status.

PSD 값은당뇨가없는환자와마찬가지로대조군, Anthocyanoside군, GBE군모두유의한변화를보여주지않았다 ( 각각 p=0.668, 0.053, 0.735). 교정시력 (logmar) 은대조군의경우 (±0.148) 에서 (±0.181) 으로악화되었으나 (p=0.005), Anthocyanoside군은 (±0.234) 에서 (±0.154) 로호전되었고 (p=0.011), GBE군은유의한변화를보여주지않았다 (p=0.809) (Table 3). 추가적으로성별, 연령, 복용약물, 고혈압, 당뇨, 안압의요소들이 MD, PSD 값, 교정시력에미치는영향을분석하기위하여일반화선형모형을산출하였다. MD 값의변화에영향을미치는것은연령 (p=0.002) 과 Anthocyanoside 복용 (p=0.019), GBE 복용 (p=0.037) 이었으며 PSD 값의변화에영향을미치는것은 Anthocyanoside 복용 (p=0.001) 이었고, 교정시력의변화에영향을미치는것은 Anthocyanoside 복용 (p<0.001) 과 GBE 복용 (p=0.004) 이었다 (Table 4). 고찰 녹내장의대표적인모집단기반연구인 OHTS (Ocular Hypertension Treatment Study) 나 CNTG (Collaborative Normal-Tension Glaucoma Study Group) 의연구에서보면고안압환자에서안압을충분히낮추어도녹내장으로전환되기도하며, 녹내장환자의안압을충분히낮추어도, 진행이줄어들긴하지만, 일정환자는여전히녹내장이진행하는것으로보고하고있다. 이러한사실로보아일부녹내장환자에서는안압하강이외에추가적인치료가필요하다는것을시사한다고할수있다. 3,4 우리의연구결과에서보면 Anthocyanoside나 GBE의복용이정상안압녹내장환자일부에서시기능의향상에도움을줄수있는것으로나타났다. 이런결과는당뇨를진단받은환자와그렇지않은환자모두에서같은결과를보여주었다. 시야검사의 MD 값은대조군에서유의한차이가없었으나 Anthocyanoside 치료군과 GBE 치료군에서는호 전되었고, PSD 값은세군에서모두의미있는차이는없었으나, 교정시력은대조군에서유의하게악화된반면 Anthocyanoside군에서는유의하게호전되었다. 특히이런결과는회귀분석을통하여 Anthocyanoside나 GBE의복용이유의한효과를가져올수있다는것을확인할수있었다. 이전의몇몇연구들에서 Anthocyanoside나 GBE의혈류개선효과에대한보고를하였었다. 동물연구에서 Anthocyanoside 가미세혈관의혈류와간질액의재배치를통하여혈류개선의이득을준다는보고가있었다. 13 Bilberry 추출물을복용한 47명의환자에서족부의미세혈류정체를감소시키는효과를보고하기도하였었다. 14 하지의정맥부전환자에서정맥의미세혈류순환과림프순환에도움을준다는보고도있었다. 15 GBE가안구혈류순환을호전시킨다고보고한연구들도있었다. 정상인 11명에서 GBE를하루 120 mg씩이틀간복용후안압이나혈압의변화없이안동맥의이완말기혈류속도가향상됨을보고한연구가있었으며, 16 같은용량으로 4주간복용후시신경유두주위의미세혈류속도, 혈류량, 부피의증가를보고한바있었다. 17 또다른연구에서는정상안압녹내장환자에서하루 160 mg씩 4주간복용후시신경유두주위의혈류량, 혈류속도의증가를보여준보고도있었다. 18 몇몇연구에서는 Anthocyanoside와 GBE의항산화작용에대한보고도있었다. 건강한쥐를대상으로 Anthocyanoside 복용이항산화효소의활성과발현에영향을미친다는보고가있었다. 19 GBE는직접유리기포촉제 (radical scavenger) 로작용을하며, 20 미토콘드리아의산화손상을막아주고역할을하고, 21,22 신경보호효과와 23 저밀도지방단백의산화를막아주는기능을가지고있다. 24 녹내장환자에서 Anthocyanoside나 GBE가도움이될수있는또다른가능성으로인지기능의향상에도움이된다는것이다. 25 대뇌소혈관허혈이녹내장환자에서더빈번하다는보고가있었으며, 26,27 Anthocyanoside나 GBE의복용 1177

5 - 대한안과학회지 2014 년제 55 권제 8 호 - 이이런허혈을개선함으로써시력이나시야검사지표에도도움을줄수있다고생각할수있다. 28 기전은명확하지않지만 Anthocyanoside와 GBE의항염증작용에대한보고도있었다. 29 이를토대로 Anthocyanoside와 GBE의시기능개선효과를보여준몇몇연구들이있었다. Lee et al 30 은 Anthocynoside 복용이근시환자에서대비감도와임상증상의개선을향상시켜준다고보고하였다. Quaranta et al 31 은 GBE를복용한정상안압녹내장환자에서 4주후시야검사지표의향상을보여준다고하였다. Kim et al 32 은황반부종을동반한비증식당뇨망막병증환자에서 Anthocyanoside 를 12개월동안복용후대비감도가호전된다고보고하였다. 그리고 42명의정상안압녹내장환자에서 GBE를 80mg씩하루 2회복용하여시야이상의진행을늦출수있다고보고한연구도있었다. 12 최근저자의연구에서는정상안압녹내장환자 332명을대상으로 Anthocyanoside와 GBE 복용후교정시력과시야검사의 MD 값이유의하게증가하였음을보고한바있다. 6 이결과를토대로녹내장의병태생리에직간접적으로영향을미칠수있는당뇨의유무에따라임상결과의차이가있는지를더많은환자수를대상으로분석을하게되었다. 본연구결과당뇨의진단여부와상관없이 Anthocyanoside와 GBE는임상적으로시기능을향상시킬수있는것으로나타났다. 이는앞선연구들에서보여준혈류개선혹은항산화효과가당뇨환자혹은비당뇨환자에만국한되지않고작용할수있다는것을시사하고있다. 본연구의제한점으로는후향적의무기록분석으로서당뇨를진단받은환자에서대조군과 GBE 치료군이상대적으로적었다는점이다. 또한약을복용하면서체내혈중농도를측정하지못하였다는단점도있다. 추후이런점을보완하여체내혈중농도와시기능개선의효과를전향적으로알아보는것이도움이될것이라고생각한다. 결론적으로우리의연구결과는정상안압녹내장환자에게있어당뇨가있는사람과없는사람모두 Anthocyanoside와 GBE가시기능의개선에도움이될수있다는것을보여주었다. 이결과는녹내장환자진료시전신질환을고려하여혈액순환개선제와항산화제를처방하는데참고가될것이라고생각한다.

Clinical evaluation of patients with nonproliferative diabetic retinopathy following medication of anthocyanoside: multicenter study. J Korean Ophthalmol Soc 2008; 49: = 국문초록 = 정상안압녹내장에서당뇨유무에따라분석한안토시아노사이드, 은행잎추출물의치료효과 목적 : 당뇨유무에따라정상안압녹내장환자에서 Anthocyanoside 제제및 Ginkgo Biloba Extract (GBE) 제제를복용하는환자들의치료효과를분석해보고자하였다. 대상과방법 : 2005 년 1 월부터 2013 년 12 월까지강북삼성병원안과외래에내원한정상안압녹내장환자를대상으로후향적의무기록분석을시행하였다. 모든환자들은 6 개월간격으로교정시력과시야검사를시행하였으며, 당뇨유무에따라나누어 Anthocyanoside 를복용한환자군과 GBE 를복용한환자군그리고둘다복용하지않은대조군의교정시력과시야검사지표를비교분석하였다. 결과 : 총 406 명중당뇨를진단받지않은환자는 255 명 ( 대조군 80 명, Anthocyanoside 군 76 명, GBE 군 99 명 ), 당뇨를진단받은환자는 151 명 ( 대조군 36 명, Anthocyanoside 군 83 명, GBE 군 32 명 ) 이었다. 치료후시야검사상 MD 값은 Anothocyanoside 군과 GBE 군에서호전되었다. PSD 값은세군에서모두유의한변화를보여주지않았다. 교정시력은대조군에서악화되었으나, Anthocyanoside 군에서는향상되었다. 이런결과는당뇨가없는환자와있는환자모두동일하였으며, 일반화선형모형분석에서전신약제복용이시기능에유의한영향을미치는것으로나타났다. 결론 : 정상안압녹내장환자에서 Anthocyanoside 와 GBE 는당뇨의유무에상관없이시기능의호전에도움을줄수있는것으로나타났다. < 대한안과학회지 2014;55(8): > 1179
