HPO HP:0000488 Retinopathy "Any noninflammatory disease of the retina. This nonspecific term is retained here because of its wide use in the literature, but if possible new annotations should indicate the precise type of retinal abnormality." [HPO:probinson] HP:0000479
HPO HP:0000489 obsolete Abnormality of globe location or size
HPO HP:0000490 Deeply set eye "An eye that is more deeply recessed into the plane of the face than is typical." [PMID:19125427] This finding should be distinguished from a prominent supraorbital ridge or inferior orbital margin. In Deeply set eyes, the globe is recessed in comparison to the overall prominence of the face. There is no known objective measurement, and diagnosing this feature depends heavily on the experience of the observer. HP:0100886
HPO HP:0000491 Keratitis "Inflammation of the cornea." [HPO:curators] HP:0011495, HP:0100533
HPO HP:0000492 Abnormal eyelid morphology "An abnormality of the eyelids." [HPO:probinson] HP:0030669
HPO HP:0000493 Abnormal foveal morphology "An abnormality of the fovea centralis, the central area of the macula that mediates central, high resolution vision and contains the largest concentration of cone cells in the retina." [HPO:probinson] HP:0001103
HPO HP:0000494 Downslanted palpebral fissures "The palpebral fissure inclination is more than two standard deviations below the mean." [PMID:19125427] HP:0200006
HPO HP:0000495 Recurrent corneal erosions "The presence of recurrent corneal epithelial erosions. Although most corneal epithelial defects heal quickly, some may show recurrent ulcerations." [HPO:curators] HP:0200020
HPO HP:0000496 Abnormality of eye movement "An abnormality in voluntary or involuntary eye movements or their control." [HPO:probinson] HP:0012373
HPO HP:0000497 Globe retraction and deviation on abduction HP:0011347
HPO HP:0000498 Blepharitis "Inflammation of the eyelids." [HPO:probinson] HP:0000492, HP:0100533
HPO HP:0000499 Abnormal eyelash morphology "An abnormality of the eyelashes." [HPO:probinson] HP:0000492, HP:0001595
HPO HP:0000501 Glaucoma "Glaucoma refers loss of retinal ganglion cells in a characteristic pattern of optic neuropathy usually associated with increased intraocular pressure." [HPO:probinson, PMID:11815354] The feature that differentiates glaucoma from other causes of visual morbidity is a characteristic pattern of damage to the optic nerve head. This is most easily recognised at the superior and inferior poles of the optic disc. The vertical cup:disc ratio (VCDR) has proved to be a simple, relatively robust index of glaucomatous loss of the neuroretinal rim. As with intraocular pressure, VCDR is a continuous variable within the population. HP:0012373
HPO HP:0000502 Abnormal conjunctiva morphology "An abnormality of the conjunctiva." [HPO:curators] The conjunctiva is a thin, sparsely vascularized transparent membrane that covers and protects the sclera (the bulbar conjunctiva), and forms the inner lining of the eyelids (the tarsal conjunctiva). HP:0030669
HPO HP:0000503 Tortuosity of conjunctival vessels "The presence of an increased number of twists and turns of the conjunctival blood vessels." [HPO:probinson] HP:0008054
HPO HP:0000504 Abnormality of vision "Abnormality of eyesight (visual perception)." [HPO:probinson] HP:0012373
HPO HP:0000505 Visual impairment "Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery." [DDD:gblack] HP:0000504
HPO HP:0000506 Telecanthus "Distance between the inner canthi more than two standard deviations above the mean (objective); or, apparently increased distance between the inner canthi." [HPO:probinson] Dystopia canthorum (also called telecanthus) describes a subtle but unusual facial feature in which the inner corners of the eyes (canthi) are spaced farther apart than normal, yet the eyes (pupils) themselves are not necessarily widely spaced. HP:0000492
HPO HP:0000508 Ptosis "The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective)." [PMID:19125427] HP:0012373
HPO HP:0000509 Conjunctivitis "Inflammation of the conjunctiva." [HPO:probinson] HP:0000502, HP:0025337, HP:0100533
HPO HP:0000510 Rod-cone dystrophy "An inherited retinal disease subtype in which the rod photoreceptors appear to be more severely affected than the cone photoreceptors. Typical presentation is with nyctalopia (due to rod dysfunction) followed by loss of mid-peripheral field of vision, which gradually extends and leaves many patients with a small central island of vision due to the preservation of macular cones." [HPO:probinson, PMID:20212494] Retinitis pigmentosa is a group of hereditary diseases of the eye. However, the term retinitis pigmentosa has also been used to describe the retinal findings characteristic of these diseases but also seen on other diseases such as Usher syndrome. It is preferable to describe the findings precisely if possible, but this term is kept for convenience. HP:0000556
HPO HP:0000511 Vertical supranuclear gaze palsy "A supranuclear gaze palsy is an inability to look in a vertical direction as a result of cerebral impairment. There is a loss of the voluntary aspect of eye movements, but, as the brainstem is still intact, all the reflex conjugate eye movements are normal." [HPO:probinson, PMID:20671861] Vertical gaze palsies can manifest as selective limitation of upgaze or downgaze. HP:0000605
HPO HP:0000512 Abnormal electroretinogram "Any abnormality of the electrical responses of various cell types in the retina as measured by electroretinography." [HPO:probinson] The electrical responses of the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells can be assessed by ERG. HP:0030453
HPO HP:0000514 Slow saccadic eye movements "An abnormally slow velocity of the saccadic eye movements." [HPO:probinson] Saccades are rapid eye movements that align the fovea with the target. HP:0000570
HPO HP:0000517 Abnormality of the lens "An abnormality of the lens." [HPO:probinson] HP:0004328
