A 46-year-old diabetic male presented with acute painless visual loss in his left eye (OS). Visual acuity was 6/36 OS with an unremarkable anterior segment examination (OU). Posterior segment showed a swollen left optic disc with large diffuse macular edema and moderate nonproliferative diabetic retinopathy (NPDR). The right eye fundus showed only mild NPDR. Optical coherence tomography and fundus fluorescein angiography were performed which revealed left macular edema and a hyperfluorescent left optic disc. Computerized tomography scan orbit and brain was normal. The patient received an intravitreal bevacizumab injection OS followed by focal laser photocoagulation 1 month later. His optic disc swelling and the macular edema subsided rapidly after the injection and his visual acuity improved to 6/6 with disc pallor.
Pilomatricoma usually presents as a solitary hard nodule located deep in the dermis. However, a variant termed anetodermic is often seen in the elderly. Instead of a hard nodule, a rapidly growing bullous lesion is seen. The authors report a 60-year-old man who presented with an erythematous bullous lesion at the left medial canthus. The lesion started as a small 3-mm papule and grew significantly to a 12-mm lesion in 5 weeks. Histopathologically, the tumor was composed of basophilic and keratinized shadow cells typical of pilomatricoma. Anetodermic changes could also be seen, represented by intralesional hemorrhage, dilated blood and lymphatic vessels, and disruption of dermal collagen fibers. The anetodermic variant of pilomatricoma was described in 1943 and accounts for only 2% of cases. Compression of vessels by the neoplastic process and peritumoral inflammatory infiltration are the proposed pathogenic mechanisms underlying the atypical findings.
Coronavirus disease (COVID-19) has been declared by the World Health Organization as a pandemic on March 11, 2020. COVID-19 predispose patients to multisystem thromboembolic events, including pulmonary emboli and deep vein thrombosis. We report a 33-year-old previously healthy man, with previous history of COVID-19 infection presented with left eye central retinal vein occlusion (CRVO) with secondary macular edema. All possible risk factors for thromboembolic events were excluded. After a single dose of intravitreal injection of aflibercept (2 mg in 0.05 ml), gradual improvement in the clinical manifestation of CRVO with complete resolution of macular edema in the left eye was observed. To the best of our knowledge, this is the first report of CRVO post-COVID-19 in Oman.
Aim:To study the outcome of repair of rhegmatogenous retinal detachment (RRD) in a tertiary center.Materials and Methods:Review of electronic medical records within a period of 29 months of consecutive patients who underwent surgical repair for RRD in Sultan Qaboos University Hospital (SQUH).Results:We included 33 consecutive patients (36 eyes). Males constituted 70% of them. The average age was 47 years. Seven eyes out of the 36 had macula-on RRD at presentation. The primary success rate with a single procedure was 86%. However, redetachment occurred in five eyes (14%). Visual acuity was either same as preoperative or better in 81% of the eyes. Giant retinal tear was found in three eyes (8%). The average follow-up period for all patients was 10.25 months (range: 3-25 months).Conclusion:Rhegmatogenous RD is not uncommon disorder. It occurs more frequently in males. However, it has a good prognosis if an intervention was performed in early stages.
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.
