[Grade III lipemia retinalis in a 14-year-old girl]. / Lipémie rétinienne grade III chez une fille de 14 ans.

A case of grade III lipemia retinalis is reported in a 14-year-old girl presenting to the emergency department with fatigue and somnolence. Diabetic ketoacidosis diagnostic of type 1 diabetes mellitus and severe hypertriglyceridemia (23,508 mg/dL) were found on routine blood tests. The patient was admitted to the hospital, kept NPO, and intravenous insulin was started. Her symptoms rapidly improved as did the lipid panel and fundus exam. Cases of lipemia retinalis described in the literature typically occur at a blood triglyceride level above 2,000-2,500 mg/dL. A high level of chylomicrons is responsible for the milky appearance of the serum and retinal vessels. Once the blood triglyceride level decreases significantly, the fundus appearance usually returns to normal.

[Keratoconus screening in a Lebanese students' population]. / Dépistage du kératocône dans une population universitaire au Liban.

OBJECTIVE: Screening for keratoconus and potential risk factors in a medical student population in Lebanon using anterior topography. POPULATION AND METHODS: We randomly selected 110 medical students doing rotations in the Hôtel-Dieu de France hospital in Lebanon between November 2009 and February 2010. Ninety-two students agreed to participate in the screening protocol, which included a questionnaire and an anterior topography. The topography was performed using the placido disk Tomey(®) Topographic Modeling System TMS-4. The results were interpreted using the analysis programs supplied with the machine and by an experienced ophthalmologist. RESULTS: Ninety-two students participated in the study (83.6%): 49 males (53.2%) and 43 females (46.8%). The mean age was 23.6±1 year. Fifty-eight students were ametropic (63.1%): 44 participants were myopic (47.8%), 40 had astigmatism (43.4%), and six were hyperopic (6.5%). Three students (six eyes) were diagnosed with keratoconus. The prevalence of keratoconus was 3.3%, of which 2.2% were already known cases. The prevalence of forme frustre keratoconus was 1.1%. Eleven students (12.1%) had a family history of keratoconus, only one was diagnosed with the disease. Atopy and eye rubbing were not found significantly related to keratoconus in this population. CONCLUSION: Keratoconus is a prevalent disease among our population of Lebanese medical students, which confirms the clinical impression that keratoconus is relatively frequent in Lebanon. Further studies need to be conducted on a larger and more representative sample to assess keratoconus prevalence and risk factors in Lebanon.
