Abstract

|
We retrospectively studied 44 eyes (44 patients) of choroidal ruptures who visited department of Hanyang university Hospital from 1983 to 1987.
Clinical and fluorescein angiographic findings were reviewed. The results were as follows
1. The incidence was higher in male(86%) and in the age of the 1st and 2nd decades (68%).
2. The major cause of ocular trauma was a blow by fist.
3. Choroidal ruptures were single in number (68%), 1-2 disc diameters in length (33%), and crescentic in shape (74%). Most(74% of choroidal ruptures were located temporal to the disc. Up to 41% of eyes with ruptures contain involvement of macula.
4. Macular lesions occurred in 77% of choroidal ruptures. The most frequent macular lesion was choroidal ruptures (64%), followed by concussive pigmentary maculopathy(30%), epiretinal membrane (23%), subretinal hemorrhage (18%), subretinal pigment epithelial hemorrhage (14%), subretinal neovascular membrane (14%), macular hole (2%), and macular cyst(2%).
Posterior segment lesions except macula were vitreous hemorrhage(20%), partial optic nerve evulsion(7%), chorioretinal ruptures (7%), choroidal detachment (2%), and macular detachment (2%), etc.
5. The associate ocular injuries were orbital floor fracture(3%), zygomatic tripod fracture(3%), traumatic hyphema(29%), iris sphincter rupture (29%), traumatic cataract (11%), and secondary glaucoma(11%), etc.
6. Subretinal neovascularization was noted in 6 eyes (14%). Five eyes developed neovascularization 2 months and 7 months after injury.
7. Most (84%)´ of the corrected visual acuity on final examination were 0.3 or less with the macular lesions. Most (90%) of the corrected visual acuity on final examination were 0.4 or more without the macular lesions.
