A Statistical Analysis of Fluorescein Angiographic Findings in Central Serous Retinopathy

ABSTRACT

The author investigated on the ratio of central serous retinopathy (C.S.R.) cases among total out patients, the distribution of age and sex, and sites of affected eye in 214 cases of C.S.R. from March 1st 1977 to February 28th 1981. Fluorescein angiography was performed in 132 eyes of 108 cases among them. Each type according to the leaking pattern on fluorescein angiography were characteritically classified as followings Type A; Leaking point is unremarkable (C.S.R. clinically). Type B; Leaking point appears at early arterial phase and increases in density gradually but the size of leaking area is not enlarged. Type C; Leaking point appears at early arterial phase and increases concentrically in its size and density. Type D; Leaking point appears at early arterial phase and increases vertically (mushroom shaped) in its size and density. Type E; Leaking point appears at early arterial phase and gradually fades out (scar formation). The results were obtained as follows 1) The eyes of C.S.R. were observed in 0.83% among total out patients. 2) As to the distribution of age, 5th decade was most frequantly affected in 37.3%. 3) As to the distribution of sex. male was observed in 80.8%. 4) Among 214 cases, unilateral involvement was observed in 85.1% without difference of both eyes and binocular involvement was nbserved in 14.9%. 5) Type C in leaking pattern was most frequantly observed in 25.8%. 6) A single leakage was observed in 59. 1% of all eyes. 7) The site of leaking point of fluorescein was found most frequantly in the upper area. 8) The direction of diffusion in leaking pattern was most frequantIy upward in type C, and outward in type D. 9) The detached size of type C and D were more larger than other types. 10) Comparing the onsets of each type, type A, B, C and D could be seen within 3 months, and type E could be found over 3 months. 11) In general, the visual acuity was severely disturbed in type D rather than the other types. And the visual disturbance was remarkable in the case of large serous detachment.
