Clinical profile and surgical outcome of pars plana vitrectomy in non-diabetic vitreous hemorrhage.

Background: Spontaneous vitreous hemorrhage is one of the common causes of ocular emergency. There are very few prospective studies on the clinical profile and surgical outcomes for patients with dense vitreous hemorrhage caused by non-diabetic and non-traumatic till date to our knowledge. Objectives: This study was conducted to better understand the etiologies, clinical profile, surgical outcome, and visual prognosis following pars plana vitrectomy for dense vitreous hemorrhage in adults with non-traumatic and non-diabetic retinopathy. Design: This was a prospective interventional study. Methods: This study was conducted in Mechi Eye Hospital (Birtamod, Nepal) from October 2018 to September 2019. All consecutive cases, 46 eyes of 46 patients, with vitreous hemorrhage that underwent vitrectomy were included in our study. There were 14 (30.4%) female and 32 (69.6%) male patients, and the average age at presentation was 43.74 ± 16.19 (17-84) years. The success rate of surgery in terms of visual outcome was evaluated. Results: The most common cause of vitreous hemorrhage was retinal vasculitis with fibrovascular changes and vascular sheathing 19 (41%). The indication of vitrectomy on patient demand was 20 (43.5%). Success rate of surgery in terms of visual outcome (functional outcome) was defined as final visual acuity of >6/60 which was 86.9%. Conclusion: The most common cause of spontaneous vitreous hemorrhage in our study was retinal vasculitis with fibrovascular changes and vascular sheathing. Vitrectomy has a good surgical outcome for spontaneous vitreous hemorrhage in terms of visual outcome (functional outcome) unless guarded by other factors like chorioretinal atrophy followed by optic atrophy and epiretinal membrane.

Subretinal Cysticercosis in a Challenging Case: A Case Report.

Ocular cysticercosis occurs rarely and may involve various parts of the eye including subretinal space. We report a case of a 42 years-old female with diminution of vision in the right eye for one month and no vision in the left eye for 10 years. Best corrected visual acuity in the right eye was 5/60. Fundus examination showed whitish round elevated cystic mass temporal to the macula. It was confirmed as a subretinal cyst by Brightness scan and Magnetic Resonance Imaging. The subretinal cyst was removed in toto by pars plana vitrectomy followed by histopathological examination of the cyst which confirmed the diagnosis of cysticercosis. This case report highlights the importance of early diagnosis of subretinal cysticercosis which could threaten the vision in a one-eyed patient. Pars plana vitrectomy could be an effective method for subretinal cyst removal in toto even in a challenging case.

Ocular metastasis from breast carcinoma simulating anterior scleritis: a case report.

BACKGROUND: Breast cancer is one of the commonest sources of ocular metastasis. Patients with ocular metastatic disease can present with a variable clinical picture. Patients with a history of breast cancer presenting with any eye symptom should be evaluated with consideration of ocular metastasis. CASE PRESENTATION: We report a case of ocular metastasis in a 46-year-old Brahmin woman presenting with right eye pain. She had been treated for stage IIIc left-sided breast cancer 2 years ago with six cycles of chemotherapy with docetaxel, adriamycin, and cyclophosphamide after undergoing modified radical mastectomy. An ophthalmic examination revealed a tender subconjunctival swelling superotemporally on retracting right upper eyelid. This finding alone indicated anterior scleritis. On examining fundus under mydriasis, an amelanotic subretinal mass could be visualized in the posterior pole superotemporal to macula. An orbital magnetic resonance imaging revealed a mass of 2 × 1 cm in size in the subretinal space of her right eye. Computed tomography of her chest was then done and showed multiple metastases in both lungs. CONCLUSION: This case report highlights the fact that any unusual ocular presentation, even one simulating anterior scleritis, in a patient with a history of breast cancer should raise suspicion of metastasis.
