Ans. 1. 3. Myopia with vertically oval-shaped tilted disc
Myopic eyes with vertically oval-shaped tilted discs have been found to have thicker temporal RNFL and more temporally positioned superior/inferior peak locations of the RNFL.1,2
Ans. 2. 1. and 4.
Nasal half of the optic disc will elevate anteriorly and temporal half of the optic disc will get depressed posteriorly.
In myopic eyes, the optic disc usually inserts obliquely. Once the optic disc tilts temporally, the nasal half of the optic disc elevates anteriorly, and the temporal half of the optic disc depresses posteriorly.2
