Limited data are available on the long-term perfusional status of patients who have undergone successful surgery for giant retinal tear (GRT) macula-off rhegmatogenous detachment (RRD). This study examines outcomes in eyes treated varying degrees GRT-associated RRD extensions and compared them with two control groups. Twenty-five emmetropic normal (control emmetropic), 20 healthy myopic myopic)...

Materials and Methods: Subjects were 21 patients who had retinal detachment with SPT. Their follow-up terms were all greater than 3 months. We undertook the crocodile technique during their subretinal surgery. The crocodile technique is a new ophthalmic technique for removing SPT using vitreous forceps, without using subretinal forceps, in small-gauge vitrectomy. After performing sufficient per...

PURPOSE The purpose of this study was to examine the optical and visual impact of tear break-up. METHODS Optical quality of the eye was assessed during periods of nonblinking by quantifying vessel contrast in the fundus image and by monitoring the psychophysical contrast sensitivity and the spatial distribution of tear thickness changes by retroillumination. All measures were obtained from th...

PURPOSE To study levels and activity of matrix metalloproteinase (MMP)-1 and -9 and their tissue inhibitor (TIMP-1) in tears of patients with vernal keratoconjunctivitis (VKC), with and without severe corneal damage. METHODS Tear samples were obtained from 16 patients with active VKC and 10 normal control subjects, after clinical evaluation and tear cytology. Tear levels of pro-MMP-1, pro-MMP...

In retinal detachment surgery, Chawla (I97I) had excellent results using a 7-mm. encircling silastic band, cauterization of the edges of the tear by cryocautery, and evacuation of the subretinal fluid (Schepens, Okamura, and Brockhurst, I957). He felt that the technique was simpler than scleral dissection and safer than the supramid encircling suture. The present study has the following aims: (...
