Recurrent Corneal Erosion Corneal disorder characterized by recurrences of epithelial erosions Trauma, Corneal dystrophy Abnormal basal epithelial layer Abnormal epithelial basement membrane Abnormal hemidesmosome Loss of anchoring fibrils 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion Clinical feature Ocular pain, redness, tearing, photophobia Typically occur on waking -> rapid eye movements during sleep 1:150 cases following traumatic abrasion 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion Appearance of affected cornea Loosely adherent and elevated epithelium Epithelial microcysts Epithelial defects Corneal infiltrates Stromal infiltrates and opacities Majority of erosion : within the lower half Last area to re-epithelize : in the midline below the horizontal meridian due to centripetally moving of healing epithelium 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion Differential diagnosis - Recurrent breakdown of corneal epithielium Self-inflicted corneal injury ; rare, history Exposure keratitis ; history, lid exam Neurotrophic keratitis ; painless Foreign bodies under the tarsal plate ; history, careful exam of conjunctiva 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion Differential diagnosis Recurrence of herpes simplex keratitis Past history of dendritic ulceration Gradual onset of pain Deep stromal infiltration Acute follicular conjunctivitis or keratoconjunctivitis Preauricular adenopathy Pseudomembrane in fornix Diffuse nature of primary epithelial involvement Decrease in sensitivity 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Recurrent Corneal Erosion Differential diagnosis Recurrence of herpes simplex keratitis 48 eyes with diagnoses of nonherpetic condition → 11 eyes positive reaction on immunofluorescent staning → 9 eyes was diagnosed as RES 9 eyes with wrong diagnosis → epithelial defects that were oval and central with hazy surrounding edges 모양은 herpes 같지만 active lesion 으로 보이지 않음.

Diagnosis Heidelberg Retina Tomograph Rostock Cornea Module (HRT II RCM) laser confocal microscope Anterior basement membrane dystrophy Abnormal epithelial basement membrane protruding forward into the corneal epithelium, the presence of epithelial microcysts Normal superficial epithelial cells and stroma Trauma Altered epithelial cells, activated keratocytes in shallow stroma and inflamed mid-stromal keratocytes

Diagnosis The tears of patients with a history of traumatic corneal abrasions and RCEs Increase MMP-9 and MMP-2 in affected and fellow eyes as compared with control eyes Basement membrane degradation and poor epithelial basement membrane adhesion

Medical Treatment Lubrication of the ocular surface Maximizing the health of the tear film Topical antibiotics Artificial tears Hypertonic solutions Bandage contact lens Doxycycline and steroids Autologous serum

Surgical Treatment Anterior stromal puncture Debridement To improve epithelial adherence by inducing scar tissue Debridement High recurrence rate Diamond Burr Polishing Epithelium removal with cellulose sponge 10-15 sec of treatment with a diamond burr to remove irregular basement membrane PTK
