purpose : to report a case of recurrent corneal intrastromal cyst containing lymph fluid case report : a 13-year-old girl presented with recurrent cyst of the left cornea, which had been drained three years before, but had gradually recurred. the cyst was successfully drained. histologic examination, cytologic analysis, and protein electrophoresis were performed on the cyst fluid. histopatholog...

INTRODUCTION Intrastromal corneal rings or segments are approved for the treatment of myopia and astigmatism associated with keratoconus. We describe a clinicopathological case of intrastromal corneal rings. For the first time, the molecular pathological findings of intrastromal corneal rings in the cornea are illustrated. CASE PRESENTATION A 47-year-old African-American man with a history of...

OBJECTIVE To evaluate the effects of the intrastromal corneal ring, a device developed to reduce myopia, on corneal asphericity in a large set of eye bank eyes. METHODS Forty-one deturgesced eye bank eyes were implanted with intrastromal corneal rings of five different thicknesses, ranging from 0.25 mm to 0.45 mm. Corneal asphericity, before and after implantation, was examined using two diff...

INTRODUCTION Corneal thinning disorders caused by keratoconus often lead to protrusion, irregular astigmatism, and even perforation. Keratoconus, like other corneal ectasia, does not have a known cause. Severe cases of keratoconus may require correction or restoration of tectonic integrity of the cornea by surgical means. Intracorneal ring segments are a new modality in the treatment of corneal...

PURPOSE To report the effect of intrastromal injection of bevacizumab in an eye with extensive corneal stromal vascularization after deep anterior lamellar keratoplasty. METHODS Bevacizumab (2.5 mg/1 mL) was injected into the deep corneal stroma of an eye with severe and extensive stromal vascularization. RESULTS Corneal vascularization regressed dramatically after deep stromal injection of...

Vascular endothelial growth factor inhibitor is an emerging therapeutic modality for various ocular diseases with neovascularization (NV). However, for corneal NV, controversy remains regarding whether bevacizumab or ranibizumab is superior. A 32-year-old female diagnosed with herpetic keratoconjunctivitis with refractory corneal NV despite two previous subconjunctival and intrastromal bevacizu...

PURPOSE To analyze corneal curvature and visual acuity after asymmetric intrastromal corneal rings implantation, not following the nomogram proposed by the manufacturer. METHODS Seven eyes of seven keratoconus patients which had asymmetric corneal rings implanted in their corneal stroma were studied. RESULTS A flattening of the average corneal keratometry was noted in all patients, as well ...
