Summary of 13 patients who lost or gained 2 or more grades of visual acuity
| Case no | Preop VA | VA at last exam | Diagnosis | Cause of altered visual acuity |
|---|---|---|---|---|
| POAG = primary open angle glaucoma, SACG = secondary angle closure glaucoma, SOAG = secondary open angle glaucoma, CRVO = central retinal vein occlusion. | ||||
| 1 | 6/24 | HM | POAG | Presumed progression of visual field loss |
| 2 | HM | NPL | SOAG | Bacterial keratitis and glaucoma progression |
| 3 | CF | PL | SOAG | Failure: glaucoma progression due to refractory rise in IOP after 2nd TDC |
| 4 | 6/60 | HM | SOAG | Retinal detachment 8 months postoperatively |
| 5 | 6/36 | HM | SACG | Glaucoma progression due to widely fluctuating IOP in between TDC sessions |
| 6 | 6/60 | HM | Aphakic | Failure: high IOP and glaucoma progression |
| 7 | 6/60 | NPL | Rubeotic (ocular ischaemic syndrome) | Ischaemic visual loss |

| 9 | 6/18 | CF | Developmental | Presumed progression of visual field loss |
| 10 | CF | PL | Developmental | Retinal detachment 7 months postoperatively |
| 11 | HM | 6/36 | Rubeotic | Resolution of vitreous haemorrhage |
