Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy the right eye, wide retrobulbar anatomy exposure, dissection structures, identification and distal section optic nerve followed by anastomosis either vicryl (group 1) or fibrin glue 2). Electroretinography recording was performed bef...
Introduction: Retinoblastoma is a malignant tumor in children. The goal of retinoblastoma treatment is to maintain vision and minimize side effects. In this study, the toxicity of the gold nanoparticle safety in vitro was investigated on an eye tumor of retinoblastoma under in vivo conditions. Materials and Methods: For the evaluation of the toxicity of gold nanoparticles using MTT test after 4...
Dirofilariasis is caused by a Filariid parasite of the genus Dirofilaria. This zoonotic infection is spread by mosquito vector from animal to human. Ocular Dirofilariasis involving the eye and adnexa is rare. A nodule in the right eye had developed in a 20-year-old soldier from Mazandaran province, north of Iran. The mass was removed surgically and measured 5x5 mm. The specimen was identifi...
To provide an animal model of human exotropia, a free tenotomy of the medial recti was performed in two infant macaques. When the animals were old enough to record eye movements with video eye trackers, we measured their ductions, ocular alignment, comitance, smooth pursuit, fixation preference, and gaze stability. Partial recovery of adduction occurred in each monkey from spontaneous re-attach...
A lot of researches have investigated the effects of topical cyclosporine A on the eye surface layers’ diseases. By now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. The aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. To reach higher corneal dru...
BACKGROUND: Normal bacterial flora of the conjunctiva, which inhibits growth of opportunistic organisms, has an important role in the prevention of ocular infections. If resident flora is inhibited by disease or long-term application of antibiotics, opportunistic pathogens overgrow, leading to disease. OBJECTIVES: The aim of this study was to investigate the effects of ophthalmic chloramphenico...
1. The Daphnia compound eye movements can be driven by a flashing light. 2. The action spectrum for the threshold light intensity required to evoke this response depends on the orientation of the stimulus light beam with respect to the animal. 3. If the light falls on the eye through the top of the animal's head the action spectrum peaks at the low wavelength end of the spectrum, while if it fa...
