Phototherapeutic keratectomy in Schnyder crystalline corneal dystrophy.

Objective: To emphasize the effectiveness of phototherapeutic keratectomy (PTK) in a patient with Schnyder crystalline corneal dystrophy (SCCD). Methods: Case report. Results: Two eyes of a patient with SCCD underwent PTK. Best corrected visual acuity (BCVA) increased from 2/10 to 8/10 (plano/−1.50 × 10) in the right eye in a lit room. BCVA of the left eye was 4/10 (−8.00/−1.50 × 170) and did not change after treatment because of anisometropic amblyopia. No recurrence was detected after 68 months of follow-up. Conclusion: PTK may be effective in the treatment of SCCD, especially if the crystals are the cause of visual disturbance.

Acquired Retraction of the Eye as the First Sign of Myositis

The authors report a patient who was diagnosed with idiopathic orbital myositis based on the findings of diplopia, worse on right gaze, globe retraction on adduction and injection at the lateral muscle tendon insertion of the left eye. Although orbital myositis as a cause of acquired retraction of the eye is rare, they wish to emphasize the importance of globe retraction with injection over the recti as an important clue for the diagnosis of orbital myositis.

Autonomic nervous system involvement in Behçet disease

We evaluated the autonomic nervous system involvement in Behçet disease by pupillary responses. Pupil cycle times were 969±189 ms and 840±62 ms patient and control groups, respectively. This difference was statistically significant. Behçet disease may affect the autonomic nervous system of the eye and is most probably related to neurologic involvement and the diseases vasculitic nature.
