| Macro-papilla, Pseudoglaucomatous Excavation | |
| The surface of the disc is 4.14 mm2. and thus nearly 2x as large as a normal disc surface of 2.7 mm². Normal disc sizes can vary by a factor up to 6x, or even larger in Handmann's anomaly. The neuroretinal rim is normal and follows the rule of thumb: inferior is larger than superior, nasal is broader than temporal: ISNT . ( Jonas et al 1989). Excavations occur in large discs more frequently and cilio-retinal vessels are more frequent. Measurements of disc size from prints of standardized photos with the Zeiss fundus camera following the formula of Littmann. | |
