Qualitative analysis of anterior segment optical coherence tomography images for dominant and secondary mechanisms showing a significant difference (p = 0.03)in primary mechanism among fellow eyes of acute angle closure glaucoma, primary angle closure glaucoma eyes, and primary angle closure glaucoma eyes.
| Glaucoma subtypes | Pupillary block | Plateau iris | Thick PIR | Exaggerated LV | |
|---|---|---|---|---|---|
| PACG (%) | Dominant | 19 (48.7) | 6 (15.4) | 4 (10.3) | 10 (25.6) |
| Secondary (12 eyes) | 2 (5.1) | – | 6 (15.3) | 4 (10.3) | |
| PACS (%) | Dominant | 27 (75.0) | 2 (5.6) | 5 (13.9) | 2 (5.6) |
| Secondary (11 eyes) | 1 (2.8) | 4 (11.1) | 6 (16.6) | ||
| Fellow eye (%) | Dominant | 31 (77.5) | 1 (2.5) | 3 (7.5) | 5 (12.5) |
| Secondary (12 eyes) | 2 (5.0) | 1 (2.5) | 1 (2.5) | 8 (20) | |
PACG: primary angle closure glaucoma; PACS: primary angle closure suspect; LV: lens vault; PIR: peripheral iris roll.
