Patients in alphabetic sequence. DA = disc area;CNV details: S = CNV also subfoveally located; C = classic CNV; O = CNV partly occult; H = haemorrhage partly obscuring the CNV; F= subretinal fibrosis Results LTT ⩾6 weeks (column 6) + = total disappearance of CNV on fluorescein angiogram. Choroidal perfusion(column 7) + = presence of choriocapillaris perfusion.Results LTT 4 months (column 8 ) ++++ = no recurrence of CNV R = recurrence after 2 months of total regression CNV. O = outgrowth CNV within 6 weeks. P = partial regression of CNV. Visual acuity post treatment (column 10 ): = means unchanged visual acuity.
