Intraocular pressure rise is predictive of vision improvement after intravitreal triamcinolone acetonide for diabetic macular oedema: a retrospective analysis of data from a randomised controlled trial

Table 2 Vision improvement in eyes treated with IVTA stratified with respect to change in IOP from baseline

	IOP change < 5 mmHg rise	IOP rise 5–9 mmHg	IOP rise ≥ 10 mmHg	P value
	(n = 17)	(n = 8)	(n = 8)	P value
1 month
Gain in BCVA ≥ 5 letters	8 (47%)	2 (25%)	7 (88%)	0.044
Mean gain in visual acuity (letters)	4.0 [-0.5 to 6.0]	3.0 [0.0 to 6.3]	6.5 [5.3 to 12.0]	0.058
6 months
Gain in BCVA ≥ 5 letters^a	9 (56%)	3 (43%)	5 (71%)	0.561
Mean gain in visual acuity (letters)^a	4.8 ± 6.5	1.4 ± 7.4	11.7 ± 9.7	0.045

IVTA = intravitreal triamcinolone; IOP = intraocular pressure.
Values are mean ± standard deviation or median with interquartile range shown in box brackets.
^an = 16, 7 and 7 for IOP rise <5 mmHg, 5-9 mmHg and ≥10 mmHg, respectively.
