OBJECTIVE To establish the sequence of events leading from vitreofoveal traction to full-thickness macular hole formation. METHODS Both eyes of 76 patients with a full-thickness macular hole in at least 1 eye were examined by biomicroscopy and optical coherence tomography. RESULTS Sixty-one fellow eyes had a normal macula. Optical coherence tomograms showed central detachment of the posteri...

We studied 34 family members at risk of having dominant progressive foveal dystrophy of Lefler, Wadsworth, and Sidbury (also called North Carolina macular dystrophy) and found 17 to be affected. Fifteen of these affected subjects were observed over at least a 10-year period for evidence of progressive macular degeneration. Only one subject showed objective evidence of progressive deterioration ...

Aim: To objectively document findings at the Silicon oil-Retinal interface, macular status and tamponade effect in Silicon Oil (SO) filled eyes using SD OCT. Methods: 104 eyes of 104 patients underwent SD OCT examination, horizontal and vertical macular scans, in silicone oil filled eyes which underwent silicone oil injection post vitrectomy for rhegmatogenous retinal detachment. Findings were ...

PURPOSE To compare change of macular thickness after uneventful cataract surgery and after cataract surgery complicated with vitreous loss, using optic coherence tomography (OCT). METHODS Twenty eyes of 20 patients who underwent cataract surgery complicated with posterior capsular tear participated in this retrospective study (Group 2). The fellow eyes of those patients who underwent uneventf...

PURPOSE To quantitatively assess retinal thickness by optical coherence tomography (OCT) in normal subjects and patients with diabetes. This study was intended to determine which retinal thickness value measured with OCT best discriminates between diabetic eyes, with and without macular edema. METHODS OCT retinal thickness was measured by a manual technique in a total of 26 healthy volunteers...

The dive reflex is the reflex mechanism most frequently considered in the aetiopathogenesis of sudden infant death syndrome (SIDS). This seems to persist in human beings as an inheritance from diver birds and amphibians. It has been reported that washing the face with cold water or plunging into cold water can provoke cardiac deceleration through the intervention of the ambiguus and the vagal d...

AIM To investigate changes in choroidal blood flow (CBF) in the foveal region in patients with type 2 diabetes. METHODS Laser Doppler flowmetry was used to determine the CBF in the foveal region in 70 patients with type 2 diabetes and 36 age and sex matched healthy subjects (control group). The patients were classified into three groups: 33 patients (33 eyes) with no diabetic retinopathy (NDR...

BACKGROUND A common clinical sign in children with subnormal visual acuity or slow visual development was iris transillumination. This was used as the inclusion criterion in a study of children shown to have a subnormal visual acuity in a general health examination at age 4 years. METHODS Refraction values, stereopsis, fundus photography, macular and nerve head appearance, and visual evoked r...

White dot fovea is thought to be a benign condition and was originally recognized in 1997 by Yokotsuka and associates. It is characterized by the appearance of multiple tiny, white dots on the surface of the foveola that typically are arranged in a ringlike pattern at the foveal margin; the appearance can simulate a macular hole. In that early report, nearly all (28 of 30) cases described were ...
