optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...

Background: Cataract surgery is one of the most common surgeries in the world, especially in elderly patients, and often performed topically with sedative agents. Ketamine is one of the most commonly used agents and the effect of different doses on intraocular pressure is in dispute. The present study investigates the effect of a low dose of ketamine on intraocular pressure in patients undergoi...

Relatively few malignant neoplasms have been described in amphibia. The one that has been studied most extensively is the Luck6 renal adenocarcinoma of the frog, Rana pipiens. This malignant tumor occurs in from two to four per cent of frogs of this species, collected in the Lake Champlain region of northern Vermont and adjoining areas of Quebec. In a series of papers Luck6 described its histop...

Two hundred and forty rabbit eyes toere exposed to focused ultrasonic radiation at either 3.5 me. or 7 me. Circumscribed chorioretinal lesion and localized destruction of the ciliary: body could, be obtained without evidence of injury to other ocular tissues. The sound beam retrodisplaces detached retinas. These observations suggest possible uses of ultrasound in retinal detachment repair, ctjc...

Injection of P815 mastocytoma tumor cells into the anterior chamber (AC) of BALB/c mice results in progressively growing intraocular tumors, whereas injection of the same dose of tumor cells subcutaneously results in rapid rejection of the tumor. Previous results indicated that AC P815 inoculation results in an unorthodox immune response characterized by suppressed delayed hypersensitivity, ele...

Retinoblastoma is the most common intraocular malignancy of childhood, yet over all it is relatively rare, affecting 1 in 78,000 to 30,000 live births. The prognosis for life is 92 percent if the tumor is detected early; however, greater than 95 percent mortality is documented for cases with advanced presentation. This paper discusses incidence, diagnosis, histopathology, and treatment of retin...

Solitary fibrous tumor (SFT) is a spindle cell neoplasm of mesenchymal origin that typically arises from the pleura. Several extrapleural sites have also been described, including the orbit, lacrimal gland fossa, and lacrimal sac. We present the clinical, imaging, and histopathologic findings of an SFT arising from the sclera that manifested as an intraocular mass with extrascleral extension.

Penetrating ocular trauma is one of the most important causes of vision loss, especially in men, and can be associated with intraocular foreign bodies. The incidence of intraocular cilia after trauma is very low. Here we report the case of a 24-year-old man who visited Poostchi Ophthalmology Clinic (Shiraz, Iran) due to a gradual vision loss in his left eye over the past 2 months. The probable ...

CASE REPORT We describe the unusual diagnosis of a ciliary body medulloepithelioma by histopathology of a subretinal membrane obtained from vitreoretinal surgery of a 10-year-old boy. The patient had a history of perforating trauma OS 2 years earlier, and both fundus exam and B-scan ultrasound revealed only a retinal detachment with a subretinal membrane. No detectable mass was present. DISCU...
