Development of Posterior Lenticonus Following the Diagnosis of Isolated Anterior Lenticonus in Alport Syndrome.

Alport syndrome is a genetic disorder that manifests as renal disease, hearing loss and ocular dysfunction. Lenticonus is one such ocular condition, in which the lens takes on an abnormal cone shape, with a protrusion either at the front or back of the lens. Both sides of the lens are rarely affected at the same time in the general patient population. Although anterior lenticonus is the type that is often reported in Alport syndrome, it is rare for such patients to have both anterior and posterior lenticonus. Here, the case of a 32-year-old male with Alport syndrome is described. The patient was diagnosed with a progressive posterior lenticonus, having been diagnosed eight years earlier with isolated anterior lenticonus. Examination of the eye revealed the typical indications of lenticonus with flecked retinopathy. The patient had co-presenting astigmatism and a refractive error, which could not be corrected by wearing contact lenses or spectacles. It is critical that such cases are anticipated and identified prior to performing surgery, so that an appropriate approach can be taken, thereby minimizing surgical complications.

Patterns of ophthalmic emergencies presenting to a referral hospital in Medina City, Saudi Arabia.

BACKGROUND: Data are required on ophthalmic cases that present to the emergency eye clinics in Madinah, Saudi Arabia for proper allocation of healthcare resources. OBJECTIVES: To determine the frequency and various diagnoses of patients presenting to the A&E at Ohud Hospital, Madinah, Saudi Arabia. METHODS: Data was collected prospectively for all patients who presented to the A&E ophthalmology clinic from June 2014 to September 2014. The data was analyzed and presented using frequency of incidence and percentages. Chi-square tests were used to evaluate the diagnoses based on age, sex and nationality. P ≤ 0.05 indicated statistical significance. RESULTS: The study sample included 868 patients. The male-to-female ratio was 1.1:1.0. The main age categories included patients ≥45 years of age (256 patients) and 251 patients between the ages of 15-30 years. Various types of Conjunctivitis was the most common diagnosis, reported in 282 patients (32.5%), and followed by dry eye syndrome in 156 (18%) patients. Nasolacrimal duct obstruction in 156 patients (18%). Eyelid infections were detected in 102 patients (12%), corneal abrasion in 102 patients (9.3%). Various eye traumas was diagnosed in 30 patients (3.5%), increased intraocular pressure (IOP) in 17 patients (2%), ruptured globe in 2 patients (0.2%) and various other non-emergency pathologies in the remaining eyes. There were no significant differences in patient's characteristics and categories of diagnoses. CONCLUSION: Non-emergent ophthalmic cases were the most common reason for the ophthalmology emergency room visits. It was observed that most cases could be referred to outpatient departments and potentially be managed by primary healthcare providers. This would be more cost effective and will also allow for better management of vision threatening ocular emergencies.
