Acute unilateral vision loss and bilateral cerebral infarction following cosmetic filler injection.

The current case report describes acute unilateral vision loss and bilateral cerebral infarction as devastating complications following cosmetic injection of hyaluronic acid to the nasal bridge in a 34-year-old female. The patient reported the onset of sudden eye pain, headache, and vision loss in her right eye. At the initial visit to the hospital, the patient had no light perception in the right eye. Examinations revealed marked ptosis and complete ophthalmoplegia with no proptosis. At the time of the patient's hospital evaluation, computed tomography, and magnetic resonance imaging were ordered. Few mottled materials (denser than blood) were observed in the cavernous sinus with a density of 106 Hounsfield units (HU), yet no air was depicted in the cavernous sinus. MRI scan revealed multiple areas of bilateral intracranial infarcts. Although cosmetic injection of hyaluronic acid has been documented as a safe procedure, vision loss remains one of the most feared complications.

Clinical Outcomes of Ruptured Periorbital and Orbital Dermoid Cysts.

PURPOSE: To evaluate the clinical outcomes of ruptured dermoid cysts. METHODS: A multicenter, retrospective study of all cases of periorbital and orbital dermoid cysts with histopathological evidence of rupture, including those with clinical rupture, was performed over a 10-year period. Demographics and clinical outcomes of ruptured dermoid cysts were recorded. Persistent inflammation was defined as the presence of edema, erythema, and discomfort for at least 28 days. RESULTS: Eighty-six cases of dermoid cysts were identified. Median age was 5.5 (range, 1-63) years. Location of cyst was either periorbital (n = 60, 70%) or orbital (n = 26, 30%). There were 29 cases with clinically apparent rupture: 27 surgically ruptured (93%) and 2 spontaneous rupture (7%). Persistent inflammation was found in 1 spontaneous cyst rupture case (50%) and 1 surgically ruptured cyst (3.7%). Older age (p = 0.01) and bony attachment (p = 0.001) were significant factors for cyst rupture, while there was no influence from cyst location (p = 0.14). CONCLUSIONS: Persistent inflammation is uncommon after surgical rupture of dermoid cysts, but likely after spontaneous rupture. Older age and bony attachment are risk factors for cyst rupture.

Isotretinoin-Related Eye Dryness in Acne Patients in Qassim, Saudi Arabia.

Background Isotretinoin is a commonly prescribed agent mainly used to treat acne vulgaris. Since its Food and Drug Administration (FDA) approval, the subject of its associations with various medical conditions has become a growing interest in many investigational studies. Methodology A retrospective study was conducted using the validated Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaire. All statistical calculations were performed using the Statistical Package for the Social Sciences (SPSS) version 27.0.1 (IBM SPSS Statistics, Armonk, NY). Results The research study involved 107 participants, predominantly Saudi nationals (98.1%), with an average age of 22 years. Regarding the total cumulative dose (TCD), 40.2% had less than 50 mg/kg, 33.6% had between 50 and 100 mg/kg, and 15.9% had more than 100 mg/kg. The majority (73.8%) did not stop using isotretinoin. The average Ocular Surface Disease Index (OSDI) score, indicating ocular surface disease symptoms, was 26.78. There was no significant association between gender, dose/duration of isotretinoin, TCD, and age, and OSDI scores. However, participants with severe OSDI scores were more likely to have worsened pre-existing eye symptoms compared to those with non-severe OSDI scores (35.1% versus 11.4%, p = 0.011). Conclusions This study contributes to the understanding of the impact of isotretinoin usage on ocular surface health. While no significant associations were found between gender, dose, duration, TCD, and age, and OSDI scores, participants with pre-existing eye symptoms were more likely to experience worsened symptoms during isotretinoin treatment.

An All-Digital, Binocular, Indirect Virtual Video Ophthalmoscope: A Novel Approach to Retinal Examination and Photography.

Purpose: We describe a novel method of digital, virtual-reality based binocular indirect ophthalmoscopy which allows for simultaneous stereoscopic recording of the examination with the potential of real-time anatomic correction of the retinal view. Materials and Methods: A provisional prototype of the all-digital, binocular, indirect virtual stereo video ophthalmoscope was designed consisting of a generic LED light source and two synchronized closely spaced side-by-side minicameras which are connected to a processor, storage media (a Samsung note-9 android smartphone in the current provisional prototype), and a virtual reality set (VISIONHMD Bigeyes H1 3D Video Glasses, in the current prototype). A custom designed android application was developed to capture the examination media and allow optional real-time anatomical correction of the examination view. Binocular stereoscopic indirect ophthalmoscopy was attempted on 15 eyes of 15 patients without and with digital real-time anatomic correction of the examination view. Results: Binocular, video, stereo ophthalmoscopic media could be successfully obtained in all 15 patients. Anatomic correction of the examination view as well as a collateral observer's view could be achieved in all 15 patients. Conclusion: An all-digital, binocular, stereo, video indirect ophthalmoscopy is a feasible alternative for conventional binocular indirect ophthalmoscopy and provides stereoscopic video documentation identical to what the examiner sees. The examination video can be streamed in the real-time of the examination for educational or telemedicine purposes.

Primary congenital glaucoma: An updated review.

Primary congenital glaucoma (PCG) is a rare disease affecting children early in life. PCG was considered untreatable with inevitable blindness. However, recent advances in biochemical and genetic studies, the introduction of new diagnostic tools, intraocular pressure (IOP) lowering medications and improvement of surgical techniques have led to a better understanding of this devastating disease and preserving the vision of affected children. This paper presents an updated and broad overview of PCG in terms of the epidemiology and genetic aspects, particularly in Saudi Arabia, the clinical presentation and diagnostic approach to PCG with major emphasis on the treatment options.

Periorbital lesions misdiagnosed as dermoid cysts.

Several periorbital lesions can be clinically misdiagnosed as dermoid cyst. We retrospectively reviewed the histopathological findings for 97 biopsied periorbital lesions with a clinical diagnosis of dermoid cyst from January 2006 to July 2016 at a single center and identified 5 cases that were eventually found to have been misdiagnosed. The main presenting symptom was a long-standing mobile painless mass with intact overlying skin below the medial aspect of the brow in 4 patients and below the center of the brow in 1 patient. The tissue diagnoses included vascular lesions (hemangiomas and cavernous venous malformation) in 4 patients and pilomatrixoma in 1 patient. The agreement between the clinical and pathological diagnosis of a periocular dermoid cyst in our series was 94.8%.
