Is noncycloplegic photorefraction applicable for screening refractive amblyopia risk factors?

Purpose: To compare the accuracy of noncycloplegic photorefraction (NCP) with that of cycloplegic refraction (CR) for detecting refractive amblyopia risk factors (RARFs) and to determine cutoff points.

Methods: In this diagnostic test study, right eyes of 185 children (aged 1 to 14 years) first underwent NCP using the PlusoptiX SO4 photoscreener followed by CR. Based on CR results, hyperopia (≥ +3.

A case of central retinal artery occlusion following embolization procedure for juvenile nasopharyngeal angiofibroma.

A 23-year-old male patient with right nasal Juvenile Nasopharyngeal Angiofibroma (JNA) developed Central Retinal Artery Occlusion (CRAO) during embolization of the tumor using polyvinyl alcohol particles before endoscopic excision. Classic CRAO management was initiated by an ophthalmologist after 12 h. Retrospective evaluation of the angiograms revealed a tiny communication between the external carotid and ophthalmic arteries which had not been noticed before embolization.

Idiopathic inflammatory pseudotumor of the eyelid.

A 40-year-old male presented with swelling and erythema in his right upper eyelid that began 4 months prior. Clinical evaluation, rheumatologic serology, sedimentation rate of erythrocyte, and C-reactive protein results were all normal. The patient also did not respond to local and systemic antibiotic therapy.

Corneal thickness in a population-based, cross-sectional study: the Tehran Eye Study.

Purpose: To determine the distribution of corneal thickness at 6 different points in an Iranian population and find any possible relationship between the thickness values and some independent variables.

Methods: As part of the "Tehran Eye Study," 410 people (800 eyes) aged 14 years and older, residing in the first 4 municipality areas of Tehran, were selected through a stratified random cluster sampling method. The participants were examined with Orbscan II to measure the corneal thickness at the central, thinnest, and 4 peripheral points of the cornea.

Effect of corneal thickness on the agreement between ultrasound and Orbscan II pachymetry.

Purpose: To study the agreement between ultrasound (US) and Orbscan II (Bausch & Lomb) measurements with different ranges of central thickness in normal corneas.

Setting: Noor Ophthalmology Research Center, Tehran, Iran.

Methods: The central corneal thickness was measured first by the Orbscan II and then with a US pachymeter in 177 right eyes.
