Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the H57 range.
Adie Syndrome
A syndrome characterized by a TONIC PUPIL that occurs in combination with decreased lower extremity reflexes. The affected pupil will respond more briskly to accommodation than to light (light-near dissociation) and is supersensitive to dilute pilocarpine eye drops, which induce pupillary constriction. Pathologic features include degeneration of the ciliary ganglion and postganglionic parasympathetic fibers that innervate the pupillary constrictor muscle. (From Adams et al., Principles of Neurology, 6th ed, p279)
Anisocoria
Unequal pupil size, which may represent a benign physiologic variant or a manifestation of disease. Pathologic anisocoria reflects an abnormality in the musculature of the iris (IRIS DISEASES) or in the parasympathetic or sympathetic pathways that innervate the pupil. Physiologic anisocoria refers to an asymmetry of pupil diameter, usually less than 2mm, that is not associated with disease.
Horner Syndrome
A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)
Iris Diseases
Diseases, dysfunctions, or disorders of or located in the iris.
Miosis
Pupillary constriction. This may result from congenital absence of the dilatator pupillary muscle, defective sympathetic innervation, or irritation of the CONJUNCTIVA or CORNEA.
Mydriasis
Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to injury of the pupillary fibers in the oculomotor nerve, in acute angle-closure glaucoma, and in ADIE SYNDROME.
Tonic Pupil
A pupillary abnormality characterized by a poor pupillary light reaction, reduced accommodation, iris sector palsies, an enhanced pupillary response to near effort that results in a prolonged, tonic constriction, and slow pupillary redilation. This condition is associated with injury to the postganglionic parasympathetic innervation to the pupil. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp492-500)
About the H57 Code Range
The H57 ICD-10 code section covers a variety of other disorders of the eye and adnexa that do not fall into more common eye disease categories. These codes are used to document diverse conditions related to the pupil’s function, ocular pain, eyelid position, and unusual eye sensations.
This section specifically includes anomalies of pupillary function such as H57.00 for unspecified anomalies and more defined conditions like anisocoria (H57.02), miosis (H57.03), and mydriasis (H57.04). Synonyms like "abnormal pupil reaction" or "pinpoint pupils" help clarify coding for pupillary disorders. It also contains codes for different types of ocular pain (H57.10–H57.13), covering pain in one or both eyes. The section includes brow ptosis (H57.81), describing drooping eyebrows. Another important group involves miscellaneous symptoms such as foreign body sensation in the eye (H57.8A) and unspecified eye disorders (H57.9), which relate to complex or unclear eye problems often described with terms like "red eye," "itching," or "ocular hypertension." Understanding these synonyms alongside their official ICD-10 codes aids accurate diagnosis documentation and effective communication in health records for these less commonly categorized eye issues.
