BACKGROUND To investigate the effects of combined corneal wavefront-guided transepithelial photorefractive keratectomy (tPRK) and accelerated corneal collagen cross-linking (CXL) after intracorneal ring segment (ICRS) implantation in patients with moderate keratoconus. METHODS Medical records of 23 eyes of 23 patients undergoing combined tPRK and CXL after ICRS implantation were retrospective...
PURPOSE To assess the psychometric properties of the National Eye Institute Refractive Error Quality of Life (NEI-RQL-42) questionnaire in keratoconus and compare these findings to patients with refractive error correction alone. METHODS The Portuguese version of the NEI-RQL-42 Quality of Life questionnaire was completed by 44 patients who had keratoconus before and after implantation of intr...
The intracorneal inoculation of a sufficient quantity of a soluble protein antigen into the eye of a rabbit produces a biphasic allergic reaction in that cornea. The earlier stage, characterized by a diffuse corneal clouding, is a manifestation of delayed hypersensitivity and is accompanied by a limbal infiltrate composed predominantly of lymphocytic-mononuclear elements. The later response, kn...
BACKGROUND Acute generalized exanthematous pustulosis (AGEP) is a rare severe pustular reaction pattern with a typical clinical picture. OBJECTIVES To characterize the histopathological features of AGEP in a large series of cases with a validated diagnosis. METHODS; A multinational retrospective histopathological study was conducted. It included 102 hospitalized patients (recruited within the...
Infection of cynomolgus monkeys with microfilariae (Mf) of Onchocerca lienalis was studied as a model for human ocular onchocerciasis. Normal monkeys and immunized monkeys were given intracorneal/subconjunctival, intracameral, or intravitreal injections of Mf or bovine serum albumin (control). Selected animals were given diethylcarbamazine citrate (DEC) orally (15 mg/kg) daily after the ocular ...
PURPOSE To test our hypothesis about whether there is water migration in the horizontal corneal plane and investigate its developmental mechanism. METHODS A fluorescein solution was intrastromally injected into normal and edematous corneas of rabbits, and the movement of the fluorescein solution was observed and recorded over time. RESULTS In normal corneas, the water flow was characterized...
THE CONCLUSIONS WHICH MAY BE DRAWN FROM THE RESULTS OF THE EXPERIMENTS HERE PRESENTED ARE: 1. The cornea of the rabbit is highly sensitive to the action of various injected bacteria. The lesions vary from insignificant, transient changes to severe, destructive panophthalmitis, with fine gradations from the mildest to the violent form of inflammation. Moreover, animals that receive the same orga...
