“…It is now thought that both anteroposterior and tangential vitreous traction are involved in the pathogenesis of IMH. Traumatic macular holes (TMHs), on the other hand, are usually associated with forceful blunt injury, although they have also been reported after inadvertent Neodymium:YAG laser 3. First described in 1869, TMH was originally hypothesized to be caused by direct impact on the eyeball 4,5.…”

Purpose To describe morphological features of traumatic macular holes (TMH) on optical coherence tomography (OCT) and to correlate them with clinical findings. Methods Seventy-three consecutive patients diagnosed with full-thickness TMH involving the fovea underwent complete ophthalmic evaluation followed by horizontal and vertical line scans using the StratusOCT. Retinal thickness at the edges of the holes, apical and basal diameters, and various clinical parameters were recorded. The approximate apical and basal areas and eccentricities of the holes were calculated. Morphological parameters were correlated with clinical findings. Results Based on OCT findings, TMHs were classified into 5 morphological types with varying average retinal thicknesses, apical areas, and basal areas. Patients who presented more than 90 days after injury had greater average retinal thickness (p=0.03) and apex areas (p=0.002) compared to those who presented within 90 days. Older patients developed more circular holes, i.e. less eccentricity of the apex (p=0.04) and base (p=0.01). Interestingly, none of the morphological parameters investigated in the current study correlated with visual acuity. Patients who presented later in the clinical course or who had greater average retinal thicknesses tended to have better vision (p=0.11 and p=0.07, respectively). Conclusions OCT evaluation may yield important insights into the pathogenesis and clinical findings of traumatic macular holes.

“…Such complications that can occur when using laser-and light-based devices in this anatomic site include posterior synechiae, iris atrophy, macular holes, iris pigment dispersion, anterior uveitis, and blindness. [10][11][12][13][14] Most of the events occur in the absence of sufficient eye protection.…”

BACKGROUNDPeriorbital rejuvenation is a common cosmetic concern. A fractional thermomechanical skin rejuvenation system was developed to offer clinical improvements from direct heat transfer.OBJECTIVEA prospective study evaluated the efficacy and safety of the device for periorbital fine lines and wrinkles.MATERIALS AND METHODSSubjects with moderate-to-severe periorbital rhytides were enrolled and underwent 4 monthly treatments with a novel device using thermomechanical fractional injury (Tixel 2; Novoxel, Netanya, Israel).RESULTSFifty-one subjects were enrolled. Mean age was 56.8 years, and 88.2% were women. Fitzpatrick skin Types I to IV were included. For Fitzpatrick Wrinkle Classification System (FWCS), mean baseline score was 5.7. Per investigator, there was a mean 2.0-grade improvement in FWCS at 3-month follow-up (p < .0001). Per 3 blinded physician raters, there was a mean improvement of 2.2 (p < .0001), 2.0 (p < .0001), and 1.2 (p < .0001) in FWCS at 3-month follow-up. Each of the raters correctly identified posttreatment images for 87.5%, 77.1%, and 75.0% of subjects. At least 2 raters agreed on grading 83.3% of subjects as responders. There were no severe adverse events. Subjects experienced minimal pain and downtime.CONCLUSIONA novel device using thermomechanical fractional injury was demonstrated to be safe and effective in the treatment of periorbital rhytides.

A 31-year-old man sustained a 1,064-nm Q-switched Nd:YAG laser injury to his left eye. One month after the injury, the fundus and optical coherence tomography (OCT) examination demonstrated a full-thickness macular hole of approximately 820 µm in diameter. After vitrectomy and internal limiting membrane peeling, OCT showed closure of the hole and a marked thinning of the foveal depression. After 12 months of follow-up, his visual acuity improved from 20/60 to 20/20. The MP1-microperimeter demonstrated increased retinal sensitivity in the area of the previous macular hole and its adjacent region and improvement of fixation from a relatively unstable status to a stable status. The macular hole remained closed 24 months postoperatively with the best corrected visual acuity 20/20. Our results suggest that vitrectomy can improve the visual function when a macular hole is caused by Nd:YAG laser injury. The improvement in the visual function includes not only visual acuity but also retinal sensitivity and fixation stability that are obtained by using the MP1-microperimeter.
