Clinical definition (Orphanet)

A rare disorder of the anterior segment of the eye characterized by ocular infection by human-pathogenic fungi, most commonly Aspergillus, Candida, or Fusarium species, which gain access into the corneal stroma through a defect in the corneal epithelium. Risk factors include trauma, ocular surface disease, contact lenses, or immunocompromised state. Patients present with pain, foreign body sensation, redness, photophobia, tearing, secretion, or blurred vision. The condition may be complicated by corneal destruction and perforation, endophthalmitis, scleritis, and panophthalmitis.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Animal models (Monarch / Alliance)

Not enriched in this build.

Literature

Is anyone studying this?

5,557

5,557 papers — among the better-studied rare conditions, though still a fraction of common-disease literature (breast cancer: over 700,000). Median papers in the last 10 years for a rare disease in this dataset (publications denominator n=5449) is 41.

5,557 papers since the earliest indexed year in this search — median last-10-year count for a rare disease in this dataset is 41 (publications denominator n=5449).

Clinical research

Is a treatment being tested?

13

interventional trials for this specific condition

13 interventional trials matched this specific condition name; 2 currently recruiting in our sample. 100 trials are registered for keratitis, the broader category — shown separately because they may or may not enrol this specific subtype.

Data as of 27 July 2026

13 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 92.8th percentile).

Recruiting interventional trials

From the matched ClinicalTrials.gov set

13 interventional trials matched after quoted-phrase search and title/condition post-filter.

Interventional trials for the parent category, exclusive of NCT IDs already counted above. Eligibility for this subtype is not guaranteed.

Recruiting under the broader category

Observational and natural-history studies

1 observational study matches this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

None of the matched observational studies is currently listed as recruiting.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

Interventional trials matched via: phrase (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Publication count (5557) is extremely high with unknown/missing prevalence — treat as possible over-matching, not proven research intensity
