Thyroid eye disease in Eastern Province of Saudi Arabia: clinical profile and correlation with vitamin D deficiency.

PURPOSE: To obtain clinical data about disease activity and severity of thyroid eye disease (TED) in a tertiary eye hospital in the Eastern Province of Saudi Arabia and to correlate this data with vitamin D levels. METHODS: A clinical observational study was conducted in a specialized eye hospital in Saudi Arabia. It included prospective enrollment of Saudi patients with confirmed TED to evaluate activity and severity according to Clinical Activity Score (CAS) and European Group on Graves' Orbitopathy (EUGOGO), respectively, and also for blood investigation, including thyroid profile and vitamin D levels. In addition, some retrospective data collection included previous medical and surgical treatment and complications. RESULTS: A total of 74 TED patients were included, with a median age of 42 years and a female predominance of 64.9%. Smokers were 18.9%. A family history of thyroid disease was noted in 12.16% of patients. There were 10.8% of patients with active TED. A moderate to severe severity level was observed in 71% of the cases, mild in 15%, and sight-threatening in 6%. Smoking and older age were associated with the active form of TED. There was a 48.4% prevalence of vitamin D deficiency among TED patients and it was not associated with TED severity or activity. CONCLUSIONS: This is the first study demonstrating the clinical profile of TED among Saudi patients. Smoking and older age were associated with TED. Vitamin D deficiency among TED patients was not worse than that of the general Saudi population.

Macular and retinal nerve fiber thickness in recovered and persistent amblyopia.

The aim of this study was to investigate the presence of increased macular or retinal nerve fiber layer thickness (RNFLT) in amblyopic eyes, find if the increased macular or RNFLT is related to the lack of response in amblyopic eyes, and to explore whether the increased central macular thickness (CMT) in amblyopic eyes is purely related to the hyperopia. This is a prospective descriptive study. CMT and peripapillary RNFLT were measured by spectral-domain optical coherence tomography to evaluate 60 patients with unilateral-treated amblyopia (median age 11.00 year). Patients were divided into two groups: 33 patients in recovered amblyopia group and 27 patients in persistent amblyopia group. The mean CMT in the recovered group was 247.31 (±23.4) versus 246.8 (±32.7) µm (p = 0.95) for the persistent group. The mean peripapillary RNFLT was 99.13 (±12.1) versus 99.9 (±14.9) µm (p = 0.85) for the persistent group. In anisometropic amblyopia, there was no significant difference in CMT and RNFLT in either group. Also there was no relation between the type of refractive error and CMT or RNFLT. There was no significant difference in CMT and RNFLT in amblyopic eyes for both the recovered amblyopia group and the persistent amblyopia group to explain the lack of response in persistent amblyopic eyes. Additionally there was no relation between the type of refractive error and CMT or peripapillary RNFLT.

Isolated Kimura Disease Presenting as a Brow Mass in a Saudi Male: A Rare Case Report.

This is a case of a 36-year-old male not known to have any medical illness complaining of left upper painless swelling in the eyebrow with no systemic symptoms, and normal physical examination apart from the eyebrow mass. Computed tomography (CT) of the head showed a well-defined hyperdense subcutaneous soft tissue lesion seen at the medial aspect of the left orbit (eyelid-extra orbital). Excisional biopsy of the eyebrow mass was done and sent for histopathological evaluation which reports consistent findings with Kimura disease (KD) as a definitive diagnosis.
