Retinal cavernous hemangioma (RCH) is a rare retinal vascular disease characterized by grape-like clusters of saccular aneurysms, usually unilateral, asymptomatic and non-progressive. The diagnosis is...
We herein describe two cases of RCH with multimodal imaging, including SS-OCTA, and compare our findings with those previously described....
On OCTA, the presence of a draining vessel, a reduction in flow signal in the SCP and DCP, and a fluid level can be observed....
These OCTA signs are in accordance with those described on conventional fluorescein angiography, allowing this invasive exam to be avoided in typical cases....
Proton therapy is an effective treatment for ocular melanoma, and other tumors of the eye. The fixed horizontal beamline dedicated to ocular treatments at Massachusetts General Hospital was originally...
To describe the experience of reevaluation and enhancement of the safety environment for one of the longest continuously operating proton therapy programs....
Several enhancements in quality control had been introduced throughout the years of operation, as described in this manuscript, to better align the practice with the evolving standards of proton thera...
Eleven failure modes identified as having the highest risk are described. Six of these were mitigated with the clinical roll-out of a new application for image-guided radiation therapy (IGRT). Others ...
Throughout the task of modernizing the safety system of our dedicated ocular beamline, FMEA proved to be an effective instrument in soliciting inputs from the staff about safety and workflow concerns,...
A man in his 70s presented with right ocular pain, vision loss and temporal headache 4 days after undergoing laser peripheral iridotomy. The patient had lost 10 lbs over the preceding 6 weeks and had ...
To report a long-term outcome of the novel combined surgical method of complete excision, corneal tattooing, and a sutureless limbal conjunctival autograft for limbal dermoid....
All patients who were referred to our clinic for limbal dermoid, and underwent a combined surgery of complete excision, corneal tattooing, and a sutureless limbal conjunctival autograft were retrospec...
During seven years, 24 patients (24 eyes) with limbal dermoid were finally enrolled. The mean age was 10.1±8.9 years old. The surgery resulted in an improved appearing ocular surface in all cases with...
Based on the results of this study, our innovative surgical method which includes complete excision with corneal tattooing and limbal conjunctival autograft can be a simple and safe procedure that ach...
The aim of this study is to describe the demographic, presenting features and associated risk factors of ocular surface squamous neoplasia (OSSN) at a tertiary eye hospital in Johannesburg, South Afri...
An interventional prospective study of patients presenting with conjunctival masses was conducted. An electronic questionnaire was completed to document demographic data, presenting history, and assoc...
There were 130 cases and 45 controls. Median age was 44 years (IQR: 35-51) with an equal gender distribution in cases. The prevalence of HIV in cases was 74% and was strongly associated with OSSN (p <...
Our study describes a sample of OSSN that is young and has no gender predisposition. The majority of cases presented with CIN lesions, rather than SCC reported in other African countries. HIV was the ...
Intraocular lymphoma (IOL) is a rare malignant intraocular lymphocytic tumor that mimics uveitis. IOL is anatomically classified into vitreoretinal lymphoma (VRL) and uveal lymphoma; most IOLs are VRL...
Our purpose is to report a patient with secondary intraocular mucosa-associated lymphoid tissue (MALT) who experienced spontaneous regression after diagnostic vitrectomy....
We retrospectively reviewed the clinical and imaging features of the case. Multimodal imaging, including fundus photograph, optical coherence tomography, fundus fluorescein angiography and ultrasound ...
A 71-year-old female presented with a subretinal lesion temporal to macula and scattered multifocal creamy lesions deep to retina in her left eye. Optical coherence tomography of the left eye showed m...
Secondary vitreoretinal MALT lymphoma is extremely rare. Spontaneous regression of intraocular lymphoma does occur....
The authors describe two cases of corneal ocular surface squamous neoplasia (OSSN), presenting at our rural eyecare centre, which were initially misdiagnosed as viral epithelial keratitis and corneal ...
Proton therapy is a key modality used in the treatment of ocular melanoma. Traditionally ocular sites are treated using a dedicated eyeline with a passively scattered proton beam and a brass aperture....
A plastic aperture system that slides into the gantry nozzle of a spot scanning proton beam was designed and constructed. It consists of an intermediate scraper layer to attenuate stray protons and a ...
Aperture alignment with radiation isocenter was determined to be within 0.31 mm at a gantry angle of 0°. A single-spot configuration with a 10 mm diameter aperture yielded film-measured lateral penumb...
The aperture system developed in this work provides a method of treating ocular sites on a gantry-based spot scanning proton system. Additional work to develop compatible gaze tracking and gating infr...
To explore the trend of ocular manifestations and interleukin (IL) during the treatment of vitreoretinal lymphoma (VRL) and to evaluate the potential effects of different intravitreal administration s...
Interventional comparative nonrandomized clinical study....
Patients diagnosed with VRL between January 2011 and January 2022 were included. Intravitreal methotrexate (MTX) injections consisting of induction, consolidation, and maintenance were scheduled. At b...
Fifty-eight eyes of 33 patients were treated with intravitreal MTX chemotherapy. A mean ± standard deviation of 9 ± 3 injections were given; 52 eyes achieved complete remission (CR). IL-10, keratic pr...
Keratic precipitates, subretinal lesions, and IL-10 could serve as indicators for therapeutic response. Intensive initial administration and adequate injection numbers would help to improve the respon...
