Congenital intrascleral cyst.

Congenital intrascleral cysts are rare. They are mostly located at the limbus with corneal involvement. We report a case of a 30-month-old boy with a bulber conjunctival cyst noticed at birth.

Interferon-alpha2b may impair myelinization of rat optic nerve.

This story investigated the effects of interferon-alpha-2b (IFN-alpha2b) on the optic nerves of 17 adult male Wistar albino rats. Animals were divided into 3 groups: 6 rats (group 1) received 7.5 units (5 mIU/m2) IFN-alpha2b-a normal treatment dose, and 6 (groups 2) received 30.

Using diazepam and atropine before strabismus surgery to prevent postoperative nausea and vomiting: a randomized, controlled study.

Objective: To evaluate the efficacy of diazepam and atropine sulfate premedication in preventing nausea and vomiting after strabismus surgery under general anesthesia.

Methods: Fifty children age 4 to 15 years who underwent strabismus surgery at Cukurova University Medical Faculty, Department of Ophthalmology, from February 2000 to June 2000 were randomized into 2 groups: 25 children in the control group did not receive premedication, whereas 25 children in the treatment group received premedication with 0.15 mg/kg diazepam and 0.

Early ultrastructural findings and superoxide dismutase levels in experimental ischemic optic neuropathy: effect of hypertension and hypotension on ischemic changes.

We induced ischemia, hypertension and hypotension in 15 rabbits in order to evaluate the ischemic changes in the optic nerve and the effect of hypertension and hypotension on ischemia. We cauterized the right internal and external carotid arteries of 15 rabbits and applied dopamine hydrochloride and glycerol trinitrate to 5 each of these rabbits. Two rabbits were used as controls.

Early clinical and ultrastructural effects of diltiazem injection on rabbit extraocular muscles.

We injected diltiazem into the left lateral rectus muscles (LR) of 10 rabbits in order to examine the ultrastructural effects of diltiazem on rabbit extraocular muscles and estimate its advantages in clinical use as an alternative to the surgical therapy of strabismus. The animals were divided into two groups according to the time of evaluation following the injection. The LR muscles of both eyes of the first group were respected 60 min after the injection, for ultrastructural examination.

Down gaze palsy due to periaqueductal lesion diagnosed by magnetic resonance imaging.

Selective paralysis of downward gaze is known to be rare. There are 6 cases reported in the literature based on neuropathologic and anatomical studies. We report a 60-year-old diabetic and hypertensive patient with isolated down gaze palsy.

Ultrastructural findings and SOD levels in experimental optic nerve injury: effect of thyroid-releasing hormone on the degenerative and regenerative processes.

We performed pressure on the left optic nerves of 24 pigs and injected intravenous thyroid-releasing hormone (TRH) to 12 of these pigs in order to evaluate the degeneration and regeneration in the optic nerves. The histopathologic, ultrastructural and biochemical examinations of the optic nerves were made at the 24th hour, 7th, 15th and 30th days. Although the light-microscopic examinations were normal, ultrastructural changes of the uncompressed optic nerves were interesting.

PUVA treatment and choroidal malignant melanoma.

Choroidal malign melanoma showing rapid progression in a boy 17 years old is presented. The patient was under therapy with methoxy psoralen + Ultraviolet A (PUVA)* for psoriasis vulgaris. He had undergone complete ophthalmologic examinations with three-month intervals from the beginning of this therapy.

Aetiological distribution of uveitis patients in Southern Turkey.

A prospective study was conducted involving 363 patients seen in the UveaImmunology Clinic of the Department of Ophthalmology, Çukurova University Medical Faculty, to determine the aetiological distribution of uveitis in this region. The results of the study were compared with previous studies carried out on different populations, and the significance of geographical, cultural and genetic factors in the occurrence of uveitis was discussed. In the authors' study group an aetiological diagnosis was established in 68.
