ABSTRACT To characterize the morphology of outer retinal holes caused by solar maculopathy, using spectral-domain optical coherence tomography (SD-OCT).
This study is an observational case series.
The SD-OCT findings of 3 patients (6 eyes) with chronic solar maculopathy are presented.
SD-OCT demonstrates a characteristic appearance of partial-thickness hole(s) in the outer retina at the fovea. In 3 of 6 eyes, there is 1 hole directly beneath the umbo. In the remaining 3 eyes, there are multifocal holes spread across the fovea. Holes in more restricted layers, as had been previously reported with time-domain OCT, were not seen. In addition, advanced visualization of SD-OCT data demonstrates a hyperreflective ring around the outer retinal hole.
SD-OCT can be used diagnose solar maculopathy. In patients with central scotomas, characteristic outer retinal hole(s) without inner retinal cystic changes may prompt the clinician to uncover an undisclosed history of sungazing. Similar OCT findings can be caused by welder's maculopathy, tamoxifen retinopathy, juxtafoveal macular telangiectasia, foveolar vitreomacular traction, or, rarely, a closed macular hole, achromatopsia, alkyl nitrite abuse, acute retinal pigment epitheliitis, or Stargardt disease.

    ABSTRACT: We report a case of accidental thermal injury due to improper use of a laser pointer obtained outside of the United States. A 13-year-old received a laser pointer as a gift and looked at a reflection of the beam. The patient underwent full ophthalmologic examination with fundus photography, spectral domain optical coherence tomography, and fluorescein angiography. Visual acuity in the left eye was 20/100 at presentation. Fundus examination and ancillary tests were consistent with thermal macular injury. The laser pointer was analyzed and found to be a green diode laser with average power output of 154 mW. Copyright © 2014 American Association for Pediatric Ophthalmology and Strabismus.

    ABSTRACT: Cyclic esotropia is a rare entity in which an esotropia presents in a regular 48-96 hour cycle, typically described as a 24-hour period of orthotropia followed by a 24-hour period of esotropia. The underlying mechanism of this phenomenon is unknown. Treatment usually involves surgical correction of the manifest strabismus. We report the case of a 3-year-old girl whose cyclic esotropia was broken following injection of botulinum toxin to both medial rectus muscles. She has remained constantly esophoric for 1 year.
