Abstract

Purpose To report a single case history of scleral rupture (SR) during silicone oil injection in a pars plana vitrectomy. Observations A 60-year-old woman with a history of pathological myopia presented with acute vision loss in her right eye. A retinal detachment, with multiple tears, was diagnosed, and she underwent vitreoretinal surgery. During silicone oil injection, a SR, with extra ocular oil leakage, was advised. Due to the small extent of the lacerated area, the SR was left to spontaneously resolve and, after three surgeries, the retina remained attached, with no internal tamponade, and the patient had not presented symptoms or signs of intracranial migration or toxicity. Conclusions and importance During silicone oil injection, it is most important to maintain a controlled eyeball pressure, especially in patients with scleral weakness, and to carefully check the drainage of air, due to the risk of SR. When oil leakage is detected in the orbital cavity, an accurate assessment may be required due to the likelihood of progression inside the intracranial structures.

Updates of pathologic myopia.

Kyoko Ohno-Matsui, Timothy Lai, Chi-Chun Lai … (2016)

Complications from pathologic myopia are a major cause of visual impairment and blindness, especially in east Asia. The eyes with pathologic myopia may develop loss of the best-corrected vision due to various pathologies in the macula, peripheral retina and the optic nerve. Despite its importance, the definition of pathologic myopia has been inconsistent. The refractive error or axial length alone often does not adequately reflect the 'pathologic myopia'. Posterior staphyloma, which is a hallmark lesion of pathologic myopia, can occur also in non-highly myopic eyes. Recently a revised classification system for myopic maculopathy has been proposed to standardize the definition among epidemiological studies. In this META-PM (meta analyses of pathologic myopia) study classification, pathologic myopia was defined as the eyes having chorioretinal atrophy equal to or more severe than diffuse atrophy. In addition, the advent of new imaging technologies such as optical coherence tomography (OCT) and three dimensional magnetic resonance imaging (3D MRI) has enabled the detailed observation of various pathologies specific to pathologic myopia. New therapeutic approaches including intravitreal injections of anti-vascular endothelial growth factor agents and the advance of vitreoretinal surgeries have greatly improved the prognosis of patients with pathologic myopia. The purpose of this review article is to provide an update on topics related to the field of pathologic myopia, and to outline the remaining issues which need to be solved in the future.

Complications associated with the use of silicone oil in 150 eyes after retina-vitreous surgery.

J Federman, H Schubert (1988)

Complicated retinal detachments (RDs) were successfully managed in 150 eyes of 170 consecutive patients by one surgeon (JLF) using silicone oil in conjunction with modern pars plana vitrectomy. Long-term postoperative complications were observed between 6 months and 5 years of follow-up. Cataracts developed in all phakic eyes and all corneas with oil-endothelial touch showed band keratopathy within 6 months. Recurrent detachments were noted in 22% of eyes during silicone oil tamponade and occurred in 13% of eyes after the oil had been removed. Other complications associated with the use of oil for vitreous surgery included pupillary block glaucoma (3%), closure of the inferior iridectomy (14%), fibrous epiretinal and subretinal proliferations (15%), pain (5%), and subconjunctival deposits of oil (3%). Without exception, within a period of 1 year the intraocular silicone oil showed some degree of emulsification, suggesting that the physicochemical characteristics of the oil injected may be an important variable in long-term complications.

Silicone oil induced glaucoma: a review.

Parul Ichhpujani, Anjana Jindal, L Jay Katz (2009)

Silicone oil has been an important adjunct for internal tamponade in the treatment of complicated retinal detachment for the past 4 decades. A known complication of its use has been the development of secondary glaucoma.
