Intracranial extension of an intramuscular haemangioma of superior rectus: case report and literature review.

BACKGROUND: Intramuscular haemangiomas are rare, benign vascular tumours that represent < 1% of all haemangiomas. When involving the extraocular muscles, haemangiomas are extremely rare, with only nine cases reported in the literature; to date there are no reported cases of extraocular muscle haemangiomas extending into the brain. CASE PRESENTATION: A 6-year-old boy with a two-week history of a painless swelling and erythema on the upper eyelid. On examination, the patient had restricted extraocular motility in all directions of gaze. In addition, the eye appeared proptotic, with chemosis and hyperaemia of the conjunctiva. Visual acuity and intraocular pressure were normal. Orbital computed tomography imaging showed a mass in the left superior rectus, with heterogeneous enhancement following contrast administration. Incisional biopsy revealed an intramuscular haemangioma of the superior rectus muscle with capillary-type vessels. The patient received an intralesional steroid, which improved the condition for a few months; however, the lesion later recurred and included an intracranial extension. CONCLUSION: This case represents the first reported case of intracranial extension of intramuscular haemangioma of extraocular muscle.

Computer vision syndrome among Saudi population: An evaluation of prevalence and risk factors.

INTRODUCTION: In the recent era of technological evolution, electronic devices have become an essential part of our lives, not merely in professional work settings, but also in daily leisure activities. Although these devices have simplified our lives, they are associated with a wide variety of health complaints. Thus, the so-called computer vision syndrome (CVS) has become a growing public health problem and has gained significant attention as it plays an important role in the quality of life of each individual, which in turn has put an increased burden on the health care system. Eye symptoms are among the most reported, yet extraocular symptoms were frequently described as adding an extra load. METHOD: An electronic survey was distributed randomly through social media platforms among the general population in Saudi Arabia, between the period from July to December 2017, irrespective of their sociodemographic factors, aiming to determine the prevalence of CVS and to verify the most common associated risk factors. RESULTS: In total, 690 participants were involved in our study, with a mean age of 33.8 years. Of these, 77.6% suffer from CVS, with eye-burning being the most common ocular symptoms (71%), as well as itching (67.5%), blurred vision (65%), tearing (62.3%), and other eye symptoms being reported. Neck/shoulder pain was found to be the most prevalent extra ocular symptom (85.2%); also back pain and headache are frequently expressed (78% and 70% respectively). A significant positive correlation was observed between CVS symptoms and time spent using the devices (P-value: 0.002). CONCLUSION: As technology advances, electronic devices have become a common tool that is used for different purposes on daily basis. We found in our study that the so-called computer vision syndrome is a growing public health problem. Thus, community education about the impact of such a lifestyle for proper handling of electronic devices must be addressed to avoid such health complaints.

Glued Intraocular Lens Combined with Endothelial Keratoplasty: A Case Report.

In an aphakic eye with corneal edema, performing Descemet's stripping automated endothelial keratoplasty (DSAEK) combined with implantation of intraocular lens can be a challenge. This case report describes a surgical technique for postsurgical aphakia with endothelial decompensation in a 42-year-old female with Marfan syndrome and subluxated lens. This technique comprised implanting DSAEK with fibrin glue-assisted sutureless posterior chamber intraocular lens. The donor lenticels were formed on a 60-kHz femtosecond laser platform (IntraLase®). Two partial-thickness scleral flaps and sclerotomies were created, and then, the Descemet's membrane was scored and stripped. A posterior chamber intraocular lens was implanted, and its haptics was pulled out through the sclerotomies and tucked beneath the flaps. The flaps were then apposed with fibrin glue. The donor lenticule was introduced to the anterior chamber and unfolded. Air tamponade was used to stabilize and center it. This technique significantly improved the uncorrected and best-corrected visual acuities of the patient, and no donor dislocations were reported. This case corroborates the findings of few similar cases that have found combined use of glued intraocular lens with DSAEK to be beneficial in such cases.
