ObjectiveTo observe the image features of eyes with indirect choroidal rupture on optical coherence tomography (OCT). MethodsFifteen patients (16 eyes) with indirect choroidal rupture were included in this study. There were 11 males (12 eyes) and 4 females (4 eyes). The mean age was (37.5±11.6) years old with a range from 19 to 57 years old. The disease course was ranged from 2 days to 43 years. One patient had bilateral lesions and 14 patients had unilateral lesions. Six patients (6 eyes) were in the acute stage, and 9 patients (10 eyes) were in the recovery stage. Average course of disease was (7.17±4.62) years in acute stage, and (7.93±13.64) years in recovery stage. Choroidal rupture locations of all the 16 eyes were in the posterior pole. Among them, 13 eyes involved foveal area, and 4 eyes with multiple fractures. OCT was used to measure the integrity of the reflective band on the photoreceptor inner segment/outer segment (IS/OS) junction layer as well as the retinal pigment epithelium (RPE), and the blood capillary complex in choroid and RPE for all patients. According to the literature, OCT reflection bands of the RPE and choriocapillaris complex can bent inward (type Ⅰ) or outward (type Ⅱ) to the center of the eyeballs with choroidal rupture. ResultsFor the 6 eyes in acute stage, 4 eyes were typeⅠ (66.67%) and 5 eyes were typeⅡ (83.33%). Three eyes (50.00%) had both typeⅠand typeⅡ OCT features. All 6 eyes (100.00%) had fuzzy or disappeared IS/OS reflective band, 5 eyes (83.33%) showed interrupted RPE reflection band, 4 eyes (66.67%) showed focal choroidal thinning. Two eyes were accompanied with macular hole and 2 eyes were with neural epithelium separated from the macular area. Among the 10 eyes during the recovery stage, 2 eyes (20.00%) were typeⅠand 8 eyes (80.00%) were type Ⅱ. Seven eyes (70.00%) had fuzzy or disappeared IS/OS reflective band, 1 eye (10.00%) showed interrupted RPE reflection band, 7 eyes (70.00%) showed focal choroidal thinning. One eye had secondary choroidal neovascularization, 2 eyes had macular hole, and 3 eyes had neural epithelium shrinkage. The proportion of typeⅠwas significantly higher in the acute stage than that in the recovery stage, and the difference was significant (P=0.001). The proportion of interrupted RPE reflection band in acute stage was also significantly higher than that of the recovery stage, and the difference was statistically significant (P=0.002). ConclusionInjury eyes with indirect choroidal rupture mainly showed RPE choroid blood capillary complex extruding inward or outward the eyeball, fuzzy or disappeared IS/OS reflective band, RPE reflective band interruption or reduced, and focal choroidal thinning.
