RESUMEN
Astigmatic changes have been shown to occur after ptosis repair due to the altered vector forces on the underlying cornea from the repositioned upper eyelid. The astigmatic change is usually transient, but it may affect a patient's vision for at least the first few months after surgery. The authors present a case of a patient who underwent ptosis repair and subsequently developed postoperative decline in best-corrected visual acuity due to previously undiagnosed keratoconus. The patient's irregular astigmatism seems to have been masked by the ptotic upper eyelid, which we postulate to have acted similar to a stenopaic slit. Correction of the upper eyelid ptosis unveiled previously asymptomatic irregular astigmatism including vertical coma, leading to alteration in the optical wavefront and resultant image degradation.

PURPOSE: To estimate the number of cases of abusive head trauma seen by pediatric ophthalmologists and analyze factors associated with physician subpoenas and court testimonies. METHODS: Pediatric ophthalmologists were surveyed about their experiences with abusive head trauma. The survey was sent to 875 active members of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). RESULTS: The response rate was 15% (132 surveys). The median pediatric ophthalmologist is consulted 10.0 (interquartile range [IQR] = 4.0 to 19.0) times per year to evaluate patients for abusive head trauma and sees 2.5 (IQR = 1.0 to 6.0) patients with probable abusive head trauma each year. Pediatric ophthalmologists were equally likely to be subpoenaed (4.6% vs 4.8%, P = .84) or to testify (1.9% vs 1.7%, P = .79) whether they did or did not perform retinal photography. Physicians were equally likely to be subpoenaed (4.8% vs 7.1%, P = .92) or to testify (2.2% vs 0.0%, P = .17) whether a child abuse team was involved in patient care or not. Geographic location had no statistical significance on how frequently pediatric ophthalmologists were subpoenaed (P = .17) or testified in court (P = .12). When a pediatric ophthalmologist was subpoenaed to court, the median number of missed clinic days was 1.0 (IQR = 1.0 to 2.0), with an estimated cost of $3,000 (IQR = $1,750 to $4,750) in lost revenue. CONCLUSIONS: Obtaining retinal imaging, having a child abuse team, and geographic location had no significant relationship with how often pediatric ophthalmologists were subpoenaed or testified in court.
