Mean corneal curvature was significantly and negatively correlated with horizontal sulcus diameter. The derived regression formula based on mean corneal curvature measurements may help predict sulcus diameters for proper sizing of posterior chamber phakic intraocular lenses.

PurposeTo report the case of a patient with large-angle hypertropia of an intramuscular hemangioma of the right superior rectus muscle (SR).MethodsA 63-year-old man with progressive vertical deviation of the right eye for the past 6 months visited our strabismus department; his condition was not painful. An examination indicated that he had 60PD of right hypertropia at distance and near in primary gaze. Additionally, a significant limitation of his downgaze was noted. The right eye appeared mildly proptotic, and the upper and lower eyelids were slightly edematous. Corrected vision was 20/20 in both eyes.ResultsOrbital magnetic resonance imaging (MRI) studies revealed fusiform enlargement of the right superior rectus muscle, with prominent but irregular enhancement following gadolinium administration. Incisional biopsy revealed an intramuscular hemangioma in the superior rectus muscle with cavernous-type vessels.ConclusionsThis case demonstrates that intramuscular hemangioma should be considered in the differential diagnosis of isolated extraocular muscle enlargement and unusual strabismus.

In cases of CNLDO with an enlarged lacrimal sac and chronic dacryocystitis, monocanalicular intubation is recommended rather than simple probing. Monoka tube intubation has the advantages of technical ease of insertion and tube removal. Moreover, the tubing does not threaten the unprobed part of the lacrimal drainage system. Endoscopic findings revealed that the probe tip protruded through a balloon-like nasal mucosa with pus around the Hasner valve.
