Figures & data

Figure 1 Rates of same-day and overnight-stay hospital admission for disorders of choroid and retina.

Table 1 Percentage of Disorders of Choroid and Retina Hospital Admission from Total Number of Admissions per ICD Code

ICD Code	Description	Percentage from Total Number of Admissions
H30	“Chorioretinal inflammation”	0.2%
H31	“Other disorders of choroid (Chorioretinal scars, choroidal degeneration, hereditary choroidal dystrophy, choroidal hemorrhage and rupture, choroidal detachment)”	4.0%
H33	“Retinal detachments and breaks”	12.3%
H34	“Retinal vascular occlusions”	4.2%
H35	“Other retinal disorders (background retinopathy and retinal vascular changes, retinopathy of prematurity, non-diabetic proliferative retinopathy, degeneration of macula and posterior pole, peripheral retinal degeneration, hereditary retinal dystrophy, retinal haemorrhage, and separation of retinal layers)”	79.3%

“Other disorders of choroid”	0.25 (0.18–0.32)	33.81 (33.10–34.52)	13,432.7%
“Retinal detachments and breaks”	19.02 (18.40–19.64)	29.68 (29.01–30.35)	56.0%
“Retinal vascular occlusions”	1.69 (1.50–1.87)	29.03 (28.37–29.69)	1,622.6%
