purpose : to evaluate corneal visco-elasticity and intraocular pressure (iop) changes measured by an ocular response analyzer (ora) after scleral buckling methods : fifty-six eyes with history of scleral buckling surgery three months ago were included in the study. corneal hysteresis (ch), corneal resistance factor (crf), corneal-compensated iop (iopcc) and goldmann-correlated iop (iopg) were m...

Buckle folds are common traps for hydrocarbon in several contractional provinces. Buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. An important parameter affecting buckle folding of a competent zone above a mobile decol...

BACKGROUND The purpose of the present study was to evaluate the microbiological spectrum and antimicrobial susceptibility in patients with scleral buckle infection. Medical records of all the patients diagnosed as buckle infection at L. V. Prasad Eye Institute between July 1992 and June 2012 were reviewed in this non-comparative, consecutive, retrospective case series. FINDINGS A total of 132...

BACKGROUND For decades, the Stroke Buckle region in the southeastern USA has had a high incidence of deaths from cerebrovascular disease relative to the rest of the country. We test here the possibility that temporary exposure to the Stroke Buckle can explain some of the excessive stroke mortality there. METHODS We examined all US death records between 1979 and 1988, noting whether individual...

CASE REPORT Intrusion is defined as erosion and protrusion of the scleral implant into the vitreous cavity. This condition may occur as a retinal detachment, vitreous hemorrhage, endophthalmitis or be without symptoms. We performed a vitrectomy alone in a patient with relapsing vitreous hemorrhage secondary to the intrusion of a scleral buckle implanted 19 years previously and left intact the i...

BACKGROUND Scleral buckling is an established modality of treating retinal detachment. Being an external implant the buckle may be prone to infections. We report such a case with a delayed presentation and a rare etiology. CASE PRESENTATION A 45 year old male presented with redness, foreign body sensation and discharge for one month in his right eye. The patient had undergone a retinal detach...

Tension analysis along the retinal surface demonstrates the advantage of meridional buckles over limbal-parallel buckles. A cylindrical sponge generates tensional forces in the retina along the long axis of the buckle and perpendicular to it. The tension perpendicular to the sponge is positive, and the retina and retinal pigment epithelium stretch in that direction. The tension along the long a...
