Parasites enter the eye through hematogenous spread. The interaction with host immune system may result in its destruction but not without collateral damage to the vital retinal structures. Currently, the accepted treatment for ocular parasitosis is surgical removal or direct laser photocoagulation. A 24-year-old Indian woman presented with abrupt painless loss of vision to 5/300. A large yellow-white lesion centered at macula was observed with associated retinal and subretinal hemorrhage and neurosensory retinal detachment. A parasite was seen protruding at the center of the lesion. Fluorescein angiography demonstrated disc leakage and vessel wall staining. Ultrasonography demonstrated a highly reflective subretinal lesion with aftershadowing. Serological test was positive for anti-cysticercus (IgM) antibody. Treatment with prednisolone and albendazole resulted in resolution of the lesion within 2 months with improvement of visual acuity to 20/400. A noncystic form of subretinal cysticercosis is likely with suggestive B-scan ultrasonography and serological investigations.
The metabolic overactivity of the retinal microenvironment appears to play a vital role in the pathogenesis of PDR. The significantly elevated biomarkers may have diagnostic, prognostic and therapeutic significance. These findings shed light on the biochemical disarray in the vitreous humour of PDR patients that could have significant management implications.
Context:Endocapsular hematoma has previously been described as a cataract surgery complication more commonly observed in eyes receiving a combined cataract and glaucoma surgery. However, it can also be a rare form of ocular bleed following thrombolysis with streptokinase.Case Report:A 65-year-old diabetic male presented to us with complain of sudden painless diminution of vision in his left eye, which he developed while he was being thrombolysed with streptokinase administered intravenously for an episode of acute myocardial infarct. On examination, left eye was pseudophakic with collection of blood in the capsular bag (Endocapsular hematoma).Conclusion:Endocapsular hematoma can be a rare form of ocular bleeding complicated by thrombolysis. Reporting this case becomes more relevant in the present era with increasing number of patients suffering from ischemic heart disease and likely to undergo thrombolysis.
Introduction: Visual impairment in Proliferative Sickle Cell Retinopathy (PSCR) starts with neovascularisation. Treatment armamentaria including diathermy, retinopexy, Autoinfarction (AI), surgical procedures and Intravitreal Anti-Vascular Endothelial Growth Factors Injections Monotherapy (AEGFM) have been applied. Some outcomes led to blindness but data on how effective AEGFM is in treating PSCR is lacking in several publications. Aim: To assess outcome and complication profile of large series of patients who underwent AEGFM after being diagnosed with PSCR. Materials and Methods: This was a retrospective analytical study conducted from October 2020 on records of patients who underwent AEGFM and other treatment on account of PSCR at Department of Ophthalmology, 37 Military Hospital, Accra, Ghana. The records were reviewed retrospectively for visual outcomes and complications. Patients’ demographic data, indications of treatment, best corrected preoperative and postoperative visual acuities, complications of surgery and length of follow-up were collected and analysed using chi-square and paired t-tests. Results: A total of 80 eyes of 40 patients (36 males and 4 females) were identified. Mean age during AEGFM (72 eyes) and vitreoretinal surgery (8 eyes) was 31.7±9.3 years (range 26-56 years) with mean follow-up period of 6±1 years (range 5-7 years). A total of 70 (87.5%), 2 (2.5%) and 8 eyes (10%) had improvement, maintenance and worsening of final visual acuities, respectively. A total of 8 (16%) eyes developed postoperative complications from retinal surgeries with Proliferative Vitreoretinopathy (PVR) being the most common. Forty (50%) eyes with old retinal Laser Photocoagulation (LP) scars reported with fresh elevated Sea Fans (SF) and Vitreous Haemorrhage (VH). LP is therefore a major source of SF formation and VH in PSCR. Conclusion: AEGFM is better treatment than other available modalities in management of undetached PSCR.
Cavernous Henangioma of the Retina is a rare, benign, congenital malformation which is non-progressive, usually unilateral, somewhat more frequent in women, and rarely a source of intraocular haemorrhage. Though the diagnosis is purely clinical, differentiation from other vascular anomalies particularly coats disease is important because of therapeutic implications. Systemic association's specifically cerebral involvement need to be ruled out on neuroimaging. Whereas Unnecessary laser treatment might at times precipitate a serious vitreous hemorrhage, a vitreous hemorrhege in a pregnant young female who otherwise had a good visual acuity, could at times point towards diagnosis of an undetected cavernous hemangioma of the retina.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
