A rare cause of intermittent respiratory distress and epiphora in the newborn: congenital dacryocystocele.

Congenital dacryocystocele is a malformation of the nasolacrimal system. Most of the cases can be successfully treated with conservative treatment options such as sac massage. Congenital dacryocystoceles with concomitant intranasal cysts causing respiratory distress in the newborns are rarely published.

A Rare Cause of Proptosis in Childhood: Langerhans Cell Histiocytosis.

A three-year-old male patient was admitted to the clinic with proptosis in his right eye. He had a history of fever with an unknown etiology. In examination, right proptosis was observed and an immobile mass was palpated at the lateral wall of the right orbita.

Simultaneous papilledema and optic disc drusen in a child.

Idiopathic intracranial hypertension is a headache syndrome characterized by elevated intracranial pressure with normal cerebrospinal fluid content, normal cranial imaging, and elevated appearance of the optic disc. We report on a 6.5-year-old boy with complaints of headache and right esotropia causing diplopia.

An unexpected outcome of blunt ocular trauma: rupture of three muscles.

Introduction: Traumatic strabismus due to isolated extraocular muscle rupture is uncommon. Treatment usually depends on the severity of both the subjective and objective findings.

Methods: We report a male patient with restricted abduction and supraduction in the right eye follow ing a blunt ocular trauma.

Inducing ocular allergy with beta-lactoglobulin: a new experimental model.

Purpose: To develop a new experimental ocular allergy animal model induced by beta-lactoglobulin (BLG), a major cow's milk allergen, and to discuss the clinical, histopathological and immunohistochemical findings.

Methods: Forty Balb/c mice were randomized and separated into groups of 10. Groups were determined according to the different concentrations of BLG drops used.

Effects of intravitreal bevacizumab in repeated doses: an experimental study.

Purpose: To evaluate the effects of repeated 1.25-mg intravitreal bevacizumab injections on cornea and uveoretinal tissues using histologic and biochemical analyses.

Methods: Twenty-four New Zealand albino rabbits were used.

Surgical treatment of an exposed orbital implant with vascularized superficial temporal fascia flap.

Orbital implants are often used for the correction of volume deficit after enucleation or evisceration. An orbital implant enhances aesthetics and improves mobility of the subsequent prosthetic eye. With advancements in technology and techniques, implant-related complication rates have been decreased.

Uncommon associations with ataxia-telangiectasia: vitiligo and optic disc drusen.

Ataxia-telangiectasia (A-T) is an autosomal recessive condition presented by progressive cerebellar ataxia, oculocutaneous telangiectasia, humoral and cellular immunodeficiencies and a predisposition to malignancy. We report on a 13 years old male patient with the diagnosis of A-T associated with uncommon clinical features; optic disc drusen and vitiligo. To our knowledge, this is the first report of A-T associated with these findings.

Persistent pupillary membranes in 3 siblings.

We report 3 siblings from a nonconsanguineous white family with bilateral persistent pupillary membranes with dissimilar forms of severity. Two of the patients required no treatment; 1 was treated surgically for occlusion of the pupillary axis and moderate visual acuity decrease. Anterior segment examination was otherwise normal in the siblings.

Intravitreal triamcinolone acetonide treatment for serpiginous choroiditis.

Purpose: To report the efficacy of intravitreal triamcinolone acetonide injection for acute treatment of a patient with serpiginous choroiditis.

Methods: A 50-year-old male patient with serpiginous choroiditis presenting with the complaint of decreased visual acuity in his right eye for the last 10 days. The best corrected visual acuity (BCVA) of the patient was counting finger from 1 meter.

Excimer laser-assisted anterior lamellar keratoplasty for keratoconus, corneal problems after laser in situ keratomileusis, and corneal stromal opacities.

Purpose: To evaluate excimer laser-assisted anterior lamellar keratoplasty to augment thin corneas as in keratoconus (<350 microm) and corneal ectasia after laser in situ keratomileusis (LASIK) and to treat anterior stromal opacities.

Effect of mitomycin C on ciliary body and intraocular pressure with various application depths: an experimental study.

Background: To evaluate the effects of mitomycin C (MMC) on intraocular pressure (IOP) and ciliary body via transmission electron microscopy when applied under conjunctiva or different depths of sclera, without performing any filtering surgery.

Methods: Thirty-six eyes of 36 New Zealand albino rabbits were used in this study. MMC was prepared in a concentration of 0.
