New Promising Therapeutic Approach for Refractory Corneal Epithelial Defects.

The purpose of this case report is to describe a case of continuous wear of a gas-permeable mini-scleral contact lens with a fluid reservoir of autologous serum (AS) combined with AS drops as a successful empirical and accessible alternative therapeutic option for refractory persistent epithelial defects in a patient with severe neurotrophic keratopathy (NK) due to severe dry eye disease and chronic contact lens wear. A 61-year-old Caucasian female with bilateral NK presented a history of multiple episodes of bilateral persistent epithelial defects, having already been submitted to three tectonic-penetrating keratoplasties in her left eye (OS). In May 2017, the patient developed de novo refractory central neurotrophic ulcers in both eyes (OU), unresponsive to conventional treatment with preservative-free lubricants, topical antibiotics, topical anti-inflammatory agents, and oral doxycycline. By March 2018, after initiating hourly AS eyedrops, the ulcer in her right eye (OD) improved to a smaller ulcer, while her OS presented complete graft re-epithelialization. In May 2018, her OD neurotrophic ulcer was complicated with fungal and subsequent bacterial secondary infection. Eventually, a therapeutic penetrant keratoplasty was required for her OD. Subsequently, her OD graft developed a de novo 6x6mm central persistent epithelial defect unresponsive to all the aforementioned therapeutic strategies. After months of unsuccessful treatment, a new therapeutic option was experimented with: a gas-permeable mini-scleral contact lens in combination with AS eyedrops. After two weeks of this treatment regimen, the corneal epithelium eventually started to regenerate, and four weeks later, the cornea was completely re-epithelized. To date, there are no signs of recurrence of the corneal epithelial defect/ulcer.

Idiopathic Acute Exudative Polymorphous Vitelliform Maculopathy: Insight into Imaging Features and Outcomes.

The authors describe imagiological findings in idiopathic exudative polymorphous vitelliform maculopathy. A 41-year-old woman complained of bilateral blurry vision. Best-corrected visual acuity was 20/20 bilaterally. Bilateral small serous neurosensory detachments in the fovea were seen at fundoscopy and confirmed by spectral-domain optical coherence tomography. Fluorescein angiography was unremarkable. Indocyanine green angiography presented discrete hyperfluorescent spots on the posterior pole. Later, more bleb-like lesions with a vitelliform appearance and hyperautofluorescent on blue fundus autofluorescence were detected. One year later, a complete resolution of the fluid was observed. To conclude, multimodal evaluation of patients with idiopathic exudative polymorphous vitelliform maculopathy is essential for the correct diagnosis of this disease.
