Punctate epithelial erosions are a pathology affecting the cornea. Signs and symptoms
It is a characterized by a breakdown or damage of the epithelium of the cornea in a pinpoint pattern, which can be seen with examination with a slit-lamp. Patients may present with non-specific symptoms such as red eye, tearing, foreign body sensation, photophobia and burning. Cause
Punctate epithelial erosions may be seen with different disorders:

Rosacea
Dry-eye syndrome
Blepharitis
Acute bacterial conjunctivitis
Trauma
Exposure keratopathy from poor eyelide closure
Ultraviolet or chemical burn
Contact lens-related disorder such as toxicity or tight lens syndrome
Trichiasis
Entropion or ectropion
Floppy eyelid syndrome
Chemotherapy i.e. cytosine arabinoside
Thygesons Superficial Punctate Keratopathy

Diagnosis
Slit lamp examination

Treatment
Due to the different underlying causes, proper diagnosis, treatment, and prognosis can only be determined by an eye care professional. Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment. Patients should discontinue contact lens wear until recovery. == References ==
Therefore, if further detail is needed a physician may request advanced imaging. Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging is the preferred advanced imaging technique for evaluation of spondylolisthesis. Preference is due to effectiveness, lack of radiation exposure, and ability to evaluate for soft tissue abnormalities and spinal canal involvement. MRI is limited in its ability to evaluate fractures in great detail, compared to other advanced imaging modalities. Computed Tomography (CT)
Computed tomography can be helpful in evaluating bony vertebral abnormalities, such as fractures. This can be helpful in determining if the fracture is a new, old, and/or progressing fracture. CT use in spondylolisthesis evaluation is controversial due to high radiation exposure. Treatment
Spondylolisthesis patients without symptoms do not need to be treated. Conservative
Non-operative management, also referred to as conservative treatment, is the recommended treatment for spondylolisthesis in most cases with or without neurological symptoms. Most patients with spondylolisthesis respond to conservative treatment. Conservative treatment consists primarily of physical therapy, intermittent bracing, aerobic exercise, pharmacological intervention, and epidural steroid injections. The majority of patients with degenerative spondylolisthesis do not require surgical intervention. Physical therapy can evaluate and address postural and compensatory movement abnormalities. Physical therapy primarily includes spinal flexion and extension exercises with a focus on core stabilization and muscle strengthening. In particular, lumbar spondylolisthesis may benefit from core stabilization exercises focusing on lower abdominal, lumbar muscles, hamstrings, and hip flexors, which may temporarily or permanently improve symptoms and improve general function. Some patients may benefit from bracing in combination with physical therapy.
