Methods: Seventeen eyes of fifteen patients diagnosed with chronic CSCR from January 2014 to March 2015 with at least 6 months of follow-up and no history of surgery were enrolled in this study. Morphologic alterations in the retinal pigment epithelium (RPE), the photoreceptor inner segment/outer segment (IS/OS) junction layer, and the outer retina were evaluated by Spectral domain optical coherence tomography (SD-OCT). The FAF images were obtained via Heidelberg Retina Angiogram using a view mode of 30 and were described using distribution patterns of retinal autofluorescence compared to background autofluorescence. After tomographic alignment of the FAF intensities with the OCT findings, we analyzed and assessed the alteration of the outer retinal layers and the characteristics of retinal autofluorescence. Results: RPE detachment lesions in SD-OCT showed little or no change in autofluorescence pattern. Five of seven eyes with s in SD-OCT showed hyper-fluorescence in FAF. All of the eyes with defects or changes of the reflective line representing the IS/OS junction in SD-OCT correlated with hyper-fluorescence in FAF. Seven of nine eyes with persistent subretinal detachment () showed specific ring-shaped hyper-fluorescence in FAF matching up with the border of the, and five eyes with photoreceptor OS elongation within showed a granular type of hyper-fluorescence within the ring-shaped hyper-fluorescence in FAF. Conclusions: In chronic CSCR, we found that s, the lesion IS/OS junction defect, the border of, photoreceptor OS elongation in SD-OCT correlate with hyper-fluorescence lesions in FAF. The areas of the autofluorescence changes in the FAF images are associated with the extent of change in the RPE and outer retina.

Spaide and Klancnik 11 은망막색소상피내에리포푸신의과다축적이나망막색소상피세포의기능저하나소실뿐만아니라리포푸신전구물질인시세포외절 (outer segment) 의변화에의해서도자가형광의세기가변한다고하였다.

8 - 대한안과학회지 2016 년제 57 권제 5 호 - 보았으며, 망막색소상피박리부위는모두자가형광변화가없었음을, 망막색소상피의융기부위는대부분자가형광의증가를보였다. 저자들이사용한단파장의안저자가형광영상은망막색소상피및망막하공간의리포푸신같은색소에의해발산되는자가형광을촬영한것이며, 리포푸신의밀도와망막색소상피세포주위의형광물질의양에의해자가형광의변화를나타낸다. 그러므로작은망막색소상피박리가있는부위의망막색소상피층은상피세포내의리포푸신변화가없음을, 망막색소상피의융기가있는부위는망막색소상피의대식작용약화로색소의응집이나섬유성삼출물의고임으로자가형광물질이축적되어있음을유추할수있다. 오래된후극부망막박리가존재한만성중심장액맥락망막병증환자에서는특징적인안저자가형광변화가관찰되었다. 오래된망막하액이있는공간은어둡고, 장액망막박리의경계부위는자가형광이증가하는 ring shape 9 이관찰되는데, 이는망막박리의경계부위에있는망막색소상피세포가많은양의절단된시세포외절을탐식하여처리하고자하여세포내에리포푸신이많이증가된상태인것으로보인다. 중심와부근에고리모양의자가형광이증가된부분은시간이지남에따라망막색소상피의기능저하로진행할수있으며, 만성중심장액맥락망막병증환자에서정상망막과비정상망막을구분하는경계로볼수있다. Spaide 14 는장액망막박리가있는동안에망막색소상피의기능저하로시세포외절을탐식하지못하여시세포외절의연장이발생하며, 오래된외절에리포푸신같은자가형광물질이축적되어불규칙한형태의자가형광의증가가발생한다고하였다. Matsumoto et al 15 은중심장액맥락망막병증에서불규칙한형태의안저자가형광의증가부위가빛간섭단층촬영을통해장액망막박리가있는공간에서시세포외절의연장부위와일치함을확인하였다. 본연구에서도빛간섭단층촬영에서시세포외절의연장이있는부위는고리형태의과형광안에알갱이형태의불규칙한과형광 (71.4%) 을보였다. 감각신경망막박리층아래시세포외절의연장이존재하는 5안중 1안에서중력방향으로안저자가형광사진에서주변부위보다과형광으로나타나는곳이관찰되고동일부위빛간섭단층촬영상과형광의 fluorophore가관찰되는것을확인할수있었다 (Fig. 4). 이는장액망막박리가장기간지속됨에따라떨어져나온감각신경망막층아래시세포외절이중력에의해아래쪽으로축적되어안저자가형광사진에서더욱진한과형광으로나타나는것으로생각된다. 본연구의한계점은첫째, 대상안을선정한기간이짧아보다많은환자에서검사결과를비교하지못해분석결과 의신뢰도가떨어진다는것이다. 둘째로백내장여부가안저자가형광신호의측정에영향을주는중요한인자로알려져있는데, 본연구에서는통제하지못하였다. 이로인해안저자가형광사진영상을얻는테크닉의차이가결과에영향을미칠수있다. 셋째로, 현재상품화된안저자가형광촬영시스템에서는자가형광의절대적인강도의정량화가불가능하다. 그래서본연구에서는동일사진의배경신호와비교하여망막의특정부위의자가형광세기변화를정성적으로표현하였다. 넷째, Spectralis HRA (Heidelberg Engineering) 의 confocal scanning laser ophthalmoscope system을이용하여황반부 크기에 raster pattern으로스캔한이미지를바탕으로비교하였기에만성중심장액맥락망막병증환자에서장기간지속된장액망막박리가중력방향으로이동하면서생기는망막주변부망막색소상피층의위축된길 (tract) 은비교분석에서제외되었다. 결론적으로만성중심장액맥락망막병증환자에서안저자가형광검사상관찰되는고리형태의과형광의병변을통해지속적인감각신경망막박리가존재할수있음을유추해볼수있다. 또한자가형광증가를보이는영역은빛간섭단층촬영상망막색소상피의작은융기, 시세포내외절경계선의변화, 시세포외절의증가와같은망막외층의변화와관련이있어망막기능이상당히저하되어있음을유추할수있다. 하지만빛간섭단층촬영결과없이안저자가형광사진만을가지고임상적으로활용하기엔무리가있어만성중심장액맥락망막병증에서의안저자가형광변화소견은좀더많은환자군을통한장기간의추척관찰이필요할것으로생각된다.
