(NVD) Early fluorescein angiography image of the eye in image OP35 demonstrating areas of vascular leakage near the disc. 1. NVD; 2. Vascular leakage
Neovascularization Elsewhere
(NVE) Fluorescein angiography image of the eye in image OP35 showing areas of vascular leakage.
Titled Disc No. 2
Titled discs are associated with high myopia or moderate oblique myopic astigmatism. Although titled discs have no systemic or neurologic association, the visual field may show bitemporal field defects usually confined to the superior quadrant. Patients with severe myopia should be evaluated by a retina specialist at least once yearly with scleral depression and indirect ophthalmoscopy due to risk of retinal tear and subsequent detachment.
Tilted Disc No. 1
Titled discs are associated with high myopia or moderate oblique myopic astigmatism. Although titled discs have no systemic or neurologic association, the visual field may show bitemporal field defects usually confined to the superior quadrant. Patients with severe myopia should be evaluated by a retina specialist at least once yearly with scleral depression and indirect ophthalmoscopy due to risk of retinal tear and subsequent detachment.
Optic Disc Enlargement No. 1
Optic Disc Enlargement, thinning (or notching) of neuroretinal rim usually beginning inferiorly and deepening of optic cup. Notching thinning of neuroretinal rim tends to occur, inferiorly, then superiorly, then temporally, and nasal is the last on to be affected. (Courtesy of 2003 Dr. Yan)
Optic Disc Enlargement No. 3
Slight thinning of neuroretinal rim inferiorly and temporally, deepening of cup, development of pallor (late finding of glaucoma).
Optic Disc Enlargement No. 2
Optic Disc Enlargement, thinning (or notching) of neuroretinal rim usually beginning inferiorly and deepening of optic cup. Notching thinning of neuroretinal rim tends to occur, inferiorly, then superiorly, then temporally, and nasal is the last on to be affected. (Courtesy of 2003 Dr. Yan)
