in order to find a reference values of intra ocular pressure (lop) in the normal male and tamale dogs on the basis of sizes ages, a research project were conducted. for this purpose, during one year (1992-1993), the lop of total 360 dogs (180 males and 180 females. either large of small sizes) refered to the small animal teaching hospital of tehran university were measured by shiotz tomometer. ...

To investigate amblyopic contrast vision at threshold and above we performed pedestal-masking (contrast discrimination) experiments with a group of eight strabismic amblyopes using horizontal sinusoidal gratings (mainly 3c/deg) in monocular, binocular and dichoptic configurations balanced across eye (i.e. five conditions). With some exceptions in some observers, the four main results were as fo...

purpose: to present a case of chorioretinitis sclopetaria with attached retina in spite of performing deep vitrectomy without retinopexy. patient and findings: a 10-year-old boy was reffered due to air-gun injury to the left eye. right eye had visual acuity of 20/16, mg-, and normal slit lamp examination and fundoscopy. in the left eye, visual acuity was count fingers at 50 cm, mg+++, anterior ...

PURPOSE To characterize posterior scleral thickness in the normal monkey eye and to assess the effects of acute (15- to 80-minute) and short-term chronic (3- to 7-week) intraocular pressure (IOP) elevations. METHODS Both eyes of four normal monkeys (both eyes normal) and four monkeys with early glaucoma (one eye normal and one eye with induced chronic elevation of IOP) were cannulated. In eac...

tears have antimicrobial, nourishing, mechanical, and optical properties and contain components such as growth factors, fibronectin and vitamins to support proliferation, migration and differentiation of corneal and conjunctival epithelial cells. lack of these epitheliotrophic factors, as in dry eye, can result in severe ocular surface disorders such as persistent epithelial defects. recently, ...

BACKGROUND Normal reading requires eye guidance and activation of lexical representations so that words in text can be identified accurately. However, little is known about how the visual content of text supports eye guidance and lexical activation, and thereby enables normal reading to take place. METHODS AND FINDINGS To investigate this issue, we investigated eye movement performance when r...

a 22 year-old woman presented with gradual visual loss in her right eye since 1990. medical and family histories were unremarkable. her visual acuity was 20/80 and 20/20 in right and left eyes respectively. slit lamp examination was quite normal with no relative afferent papillary defect.fundi of both eyes revealed subretinal lesion with optic nerve head involvement and subretinal fluid in papi...

PURPOSE To measure corneal and total optical aberrations in the normal and treated eye of a unilateral aphakic patient to (1) cross-validate techniques in an eye in which corneal and total aberrations should be almost identical (aphakic eye) and (2) compare the interactions of corneal and internal aberrations in the normal eye with those in the aphakic eye. SETTING Instituto de Optica, Consej...
