Our purpose is to describe the appearance of a new origin of Cornea Verticillata through a clinical case of a 67-years-old female
patient with breast cancer who was being treated by Ribociclib and attended the consultation of ophthalmology by halos vision.
Exploration was performed by visual acuity, slit lamp examination, fluorescein staining, retinography and corneal topography. We
observed cornea verticillata in our patient, she did not need specific treatment and the findings remained stable over time.

Cornea Verticillata a is an often asymptomatic and reversible
corneal alteration caused by certain diseases and drugs [1,2]. Our
goal is to announce a new cause of this finding. Ribociclib is a
drug used in breast cancer therapy [3]. It is important to know the
adverse effects of new drugs and their ocular repercussion. Herein
we present a clinical case of Cornea Verticillata as a consequence of
Ribociclib therapy.
A 67-year-old woman with a history of breast cancer comes
to our office for feeling halos and blurred vision. The patient
was diagnosed with metastatic breast cancer for 2 years, treated
by tumerectomy and oral Ribociclib (500 mg daily). She had no
known ocular history or allergies. The visual acuity with its optical
correction was 0.8 (decimal scale) for both eyes. In the anterior pole
biomicroscopy, a transparent cornea with pigmented verticillata
keratopathy was seen (Figure 1). An incipient nuclear cataract
could also be observed. The rest of the parameters corresponded to
normality. The intraocular pressure was 15 mmHG in both eyes and
the fundoscopy showed no significant findings. A Schirmer type I
test was performed, which was 20 mm in the right eye and 15 mm
in the left eye. Fluorescein staining showed no epithelial damage
(Figure 2). The corneal tomography (Pentacam, Okulus Optikgerate
GmbH, Wetzlar, Germany) revealed a regular astigmatism with
the rule, with central pachymetry of 540 microns in the right eye
and 530 microns in the left eye. There were no corneal thinning
points or irregularities in either eye (Figure 3). Retinography and
autofluorescence, as well as optical coherence tomography, did not
show significant findings. Given the good visual acuity of the patient
and the benign finding of verticillata cornea secondary to Ribociclib,
observation and monitoring of the lesion was decided. The patient
was evaluated at 3 and 6 months after the consultation, resulting
in a similar exploration to the previous ones. She is currently in
treatment with Ribociclib and topical lubricants on demand.

The Verticillata cornea is a keratopathy, often unnoticed, that
occurs in the corneal apex after the use of certain drugs or in the
context of a systemic disease [4]. Its characteristic shape allows
diagnosis through biomicroscopic exploration. It is usually a
benign and not very symptomatic disorder that disappears if it is
secondary to a triggering factor. Among the diseases most related
to this picture are Fabry disease or Cystinosis [5]. The drugs that
most often cause cornea Verticillata are amiodarone, chloroquines,
tamoxifen and indomethacin, among many others. Ribociclib is an antineoplastic drug that inhibits cyclins and is administered
orally as a treatment for metastatic breast cancer [6]. Its indication
is approved for breast neoplasms with positive Hormone
Receptors and negative Epidermoid Growth Receptor [7]. Since
the introduction of the drug, the resistance to previous therapies
in this type of tumors has been reduced by 20%. Among the most
frequent side effects are neutropenia, alteration of liver enzymes
and digestive symptoms such as nausea, diarrhea or vomiting. At
present, the use of this drug has not been linked to the appearance
of Verticillate cornea. It is always important to perform a detailed
ocular exploration of the cornea verticillate secondary to drugs,
since we can also find associated retinal toxicity. The retinography
and the autofluorescence image can help us in the screening. The
withdrawal of the drug is usually not necessary due to its benignity,
although close monitoring of the lesions is recommended.
The multidisciplinary work between oncologists and
ophthalmologists is necessary for the management of these
patients. Ribociclib could result a new cause of Cornea Verticillate.
