1 = 증례보고 = 대한안과학회지 213 년제 54 권제 6 호 J Korean Ophthalmol Soc 213;54(6): pissn: eissn: 전안부빛간섭단층촬영기를이용한백내장절개창의크기에따른창상치유과정의형태학적관찰 김진형 김태임 김응권 이형근 연세대학교의과대학안과학교실, 시기능개발연구소 목적 : 백내장수술후절개부위를전안부빛간섭단층촬영기로촬영하여시간에따른창상치유과정의변화를관찰하였다. 대상과방법 : 백내장수술을시행받은총 34 명 (44 안 ) 을절개범위에따라 1 군 (2.2 mm) 과 2 군 (2.8 mm) 으로분류하고절개부위를술후 1 일, 1 주일, 1 개월째빛간섭단층촬영기로기록하여, 시간에따른절개각도, 절개길이, 각막상피 / 내피결손길이, 각막상피 / 내피결손면적, 절개부위의최대각막두께등을측정하고데스메막박리의유무를비교하였다. 결과 : 수술후 1 개월까지각막내피결손길이, 각막내피결손면적은 1 군에서 2 군보다더높은경향을보였고, 술후 3 일째차이는통계학적으로유의미하였다 (p=.15,.27). 두절개군간절개각도, 절개길이, 절개부위최대각막두께는통계학적유의한차이는없었고, 데스메막박리는절개창크기에따른발생비율의차이는없었으나, 연령이높고수술후안압이낮을수록발생이증가하였다 (p.5). 결론 : 두절개군모두우수한창상치유과정을보였으며, 데스메막박리를줄이기위해선고령의환자일수록술중절개부위조작과술후안압조절에더유의해야할것으로생각한다. < 대한안과학회지 213;54(6): > 초음파유화술의도입과수술기법, 인공수정체의발달로점점작은절개창에의한백내장수술이가능해지게되었고, 이러한작은절개창기법은술후상처부위의빠른회복과술중발생할수있는각막난시를최소화할수있다는장점이있어시력의질을높이고자하는시도의일환으로널리선호되고있다. 1-4 기존의 2.8 mm 절개창백내장수술에이어 2.2 mm 기법이많이사용되고있고, 절개창크기가점점감소하여현재는 1.5 mm 이하의크기를통한 bimanual technique까지소개되어실제임상에적용되고있는실정이다. 하지만관류와흡입을분리시키는이기법은관류량, 흡입속도의제한으로수술시간이길어지고, 술중전방유지의불안정과함께기존의인공수정체삽입을위해선추가절개창연장이필요하다는단점이있으며, 1.5 mm 이하절개창에맞게고안된인공수정체삽입시에도단면 (singe plane) 을이용한절개창에의해술후지속적인누출과치명적인안내염발생의원인이될수있다. 한편 1992 Received: Revised: Accepted: Address reprint requests to Hyung Keun Lee, MD Department of Ophthalmology, Gangnam Severance Hospital, #211 Eonju-ro, Gangnam-gu, Seoul , Korea Tel: , Fax: shadik@yuhs.ac * 이논문의요지는 211 년대한안과학회제 16 회학술대회에서구연으로발표되었음. 년 Fine A 에의해소개된무봉합투명각막절개술 (sutureless self-healing clear corneal incisions : CCIs) 은절개창크기감소로가능해진기법으로수술시간의단축, 봉합에의한난시유발감소, 빠른창상회복이가능하다는장점이있지만, 술후절개창을통한창상유출과안내염발생을증가시킨다는결과가여러논문에의해보고된바있다 무봉합, 작은크기의각막절개술로요약되는최근백내장수술기법이여러장점이있음에도불구하고, 안내염등중대한합병증발생과의관련성이있는것으로알려졌으며, 최근전안부빛간섭단층촬영의도입으로쉽고빠르게실제창상부위를고해상도영상으로분석하는것이가능해지게되었다. 시간에따른상처부위의형태학적변화와술후합병증발생과의관련성을알아보고이를임상에적용함으로써보다안전하고빠른창상회복에중요한역할을할것으로생각한다. 따라서이에본연구에서는최근가장많이사용되는 2.2 mm 동축소절개백내장수술군 (Microcoaxial cataract surgery: MCCS) 과기존의 2.8 mm 백내장수술군 (conventional cataract surgery: CCS) 으로나누어, 술후 1일, 7일, 3일째절개부위를전안부빛간섭단층촬영기를통해촬영하고두절개군간의절개각도, 절개길이, 절개부위최대각막두께, 각막상피 / 내피결손길이및면적, 데스메막박리유무등을관찰하여시간에따른창상치유과정을비교해보고자하였다

8 - 대한안과학회지 213 년제 54 권제 6 호 - 이와반대로봉합실이유발하는염증으로인한상처치유지연가능성또한배제할수없고, 앞으로절개창크기, 절개창단면모양, 술중조작등의요인을통제하여봉합이창상회복에미치는영향과관련된연구가필요할것으로생각한다. 본연구에서 LOCS (Lens Opacities Classification System) III 분류에의한백내장정도를살펴보면, 피질혼탁및핵경화는두절개군간유의한차이가없었으나, 후낭하혼탁이통계적유의한차이로 2.2 m 절개군에서더심하였다. 이처럼수정체경화도와두께가증가함에따라, 총수술시간, 초음파사용시간, 강도의증가및초음파기구의각막내피와의접촉기회가증가함에따라, 열, 기포발생등으로인한각막내피손상이증가할수있다는점을감안할때, 본연구에서실제평균초음파유화흡인술시간및평균수술시간에서두군간의통계학적유의한차이는없었으나, 술중내피손상에영향을줄수있는원인으로후낭하혼탁의차이를생각해볼수있으며, 이는본연구의한계점이라할수있다. 본연구의또다른한계점으로백내장절개창평가에있어동일검사자가전안부 OCT를이용하여절개창부위를 3회반복시행하여얻은영상중최대결손면적의이미지를기준으로평가하였는데, 이는 2차원적단면적, 길이를측정한것으로실제술후발생하는 3차원적절개창의부피, 면적을온전히반영하지못한다는한계점이있다. 하지만본저자는최대결손단면적이실제결손량과양의상관성을보인다는가정하에이를상처치유과정의지표로삼고연구를진행하게되었다. 한편예전논문에서발표된데이터를살펴보면, 술후 1일째절개부위각막상피폐쇄율은 1% 에달하였다. 14,19-22 본연구에서도각막상피결손은발견되지않았지만, 이에반해각막내피결손은대부분의경우에서관찰되었다. McGowan 23 은술후창상회복과정에서각막내피세포가펌프기능을통해각막기질쪽으로물을빨아들이거나 (suction) 내보내는힘에저항하는각막수화 (corneal hydration) 기능으로써각막기질수분의양을일정하게유지하려한다고하였다. 이러한내피세포의흡인작용 (suction) 의방향이각막내피세포결손폐쇄에는도움이되지만, 각막상피결손이발생한경우, 창상가장자리회복에반대되는힘으로작용해안내염발생을높일수있다고하였으며, 술후초기전안부빛간섭단층촬영의도움으로각막상피결손여부를확인하는것이창상유출, 감염성안내염등합병증예방에중요한역할을할것으로생각한다. 한편술중에시행되는기질수화 (stromal hydration) 는술후내피세포기능저하에의한흡인력을보상함으로써, 실제각막내피결손발생비율을감소 시킨다는보고가있었는데, 본연구의두절개창군모두기질수화를시행하여, 기질수화가내피결손길이, 내피결손크기에미치는영향은확인하지못하였다. 15,21,24 Calladine and Tanner 21 은기질수화를시행한군과시행하지않은군에서데스메막박리비율이 63%, 25% 로차이가있다고하였는데, 이는기질수화시각막기질층의팽창하려는힘과부종없이본구조를유지하려는데스메막의물리적특성의차이에의한것이며, 술후안압이높을수록발생비율이감소하는데그원인으로안압에의해박리된데스메막이노출된각막표면으로압박되기때문이라고하였다. 25 이는술후 1일째데스메막박리박리없는환자군의안압이박리가관찰된환자군보다통계적으로유의하게높게나타난본연구의결과와일치하는것이다. Xia et al 26 은 3.2 mm 투명각막절개시행후술후 1일째전안부단층촬영결과데스메막박리비율이 82% 이며, 술전낮은안압과관련성이있고, 그외연령, 술후안압, 각막내피세포, 각막두께등과는관련이없다고하였다. 본연구에서시행된술후 1일째데스메막박리비율은 2.2 mm 군에서 75.%, 2.8 mm 군에서 8.7% 로 Xia et al 26 의수치와비슷하였고, 술후 1, 7일째데스메막박리는술후낮은안압과유의한관계가있었다. 본결과에따르면, 술후낮은안압이데스메막박리와관련성이있었고, 연령이높은환자일수록그발생비율이높고, 오래지속되는경향을나타냈는데연령에따른데스메막박리관련성은통계학적으로술후 1일째에만유의미하였다 (p=.35). Can et al 24 은술후안압이높을수록데스메막박리비율과각막내피결손비율이감소한다고하였는데, 본연구결과에따르면술후안압과각막내피결손의길이, 면적과의유의한관련성은없었지만데스메막박리의비율을감소시킨다는점을볼때, 술후안압이구조적창상치유과정에영향을미침을알수있었다. 본연구에서백내장수술후절개창의변화를전안부빛간섭단층촬영을통해관찰한결과, 2.2 mm, 2.8 mm 절개군모두중대한합병증발생없이우수한창상치유과정을보여주었다. 본논문에서소개된절개창부위의결손길이, 결손면적, 데스메막박리항목은앞으로백내장술후창상치유과정의기준지표로활용되어합병증예방과창상부위안정화에기여할것으로기대된다. 본연구에서관찰되지는않았지만, 창상유출과관련성이높은각막상피결손이관찰될경우, 술후창상관리에각별히유의해야하며, 술후정기적으로실제각막결손의길이, 면적을관찰, 측정함으로써창상회복정도를파악할수있을것으로생각한다. 본연구를통해데스메막박리의경우, 절개범위와관계없이연령, 술후안압과밀접한관련이있음을알수있었고, 데스메 884

10 - 대한안과학회지 213 년제 54 권제 6 호 - =ABSTRACT= The Morphological Changes in Main Corneal Incision (2.2 mm vs. 2.8 mm) Evaluated Using Anterior Segment Optical Coherence Tomography Jin Hyung Kim, MD, Tae Im Kim, MD, PhD, Eung Kweon Kim, MD, PhD, Hyung Keun Lee, MD The Institute of Vision Research, Department of Ophthalmology, Yonsei University College of Medicine, Seoul, Korea Purpose: To investigate wound characteristics and ultrastructural changes in the 2.2-mm and 2.8-mm main corneal incisions. Methods: Forty-four eyes of 34 patients undergoing cataract surgery were randomized to receive a 2.2-mm or 2.8-mm main corneal incision. All incisions were evaluated 1, 7, and 3 days postoperatively using anterior segment optical coherence tomography. The angle, length, maximal thickness of the incision, and if present, corneal gap length and incision gap area were calculated. The existence of Descemet s membrane detachment was recorded. Results: The mean endothelial gap length and gap area of the 2.2-mm wound were larger than the 2.8-mm, with the only statistically significant difference observed on postoperative day 3 (p =.15 and.27, respectively). There was no difference in the mean incision angle, length, and corneal thickness between the 2 incision sizes. The ratio of Descemet s membrane detachment increased with older age and low postoperative IOP, but not associated with incision size (p <.5). Conclusions: Both the 2.2-mm and 2.8-mm main corneal incisions showed excellent wound healing outcome without significant postoperative complications. Older patients with low postoperative IOP required a more careful wound care management. The incision parameters in the present study can be used as an indicator of the healing process to reduce wound-related complications.
