Purpose To report the management of accidental macular photocoagulation during a 750-nm Alexandrite laser hair removal procedure. Methods Single case report with images. Results A 23-year-old girl presented with an immediate visual field defect in her right eye after direct inadvertent exposure to a single discharge from a 750-nm Alexandrite laser used for laser hair removal. Baseline Snellen visual acuity was 20/20 in the involved right eye but the patient reported a subjective visual field defect. She was treated with oral methylprednisolone that was started at a dose of 1 mg/kg/day and then gradually reduced. Six months after the initial exposure, the final visual acuity was 20/20 and there was a significant improvement in the macular lesion. However, the subjective visual field defect continued. She underwent multimodal retinal imaging with optical coherence tomography, fundus fluorescence angiography, and optical coherence tomography angiography in addition to a visual field test and microperimety. Conclusion The present case documents a gradual visual and anatomical improvement following macular photic damage after accidental occupational exposure to a 750-nm Alexandrite laser. The treatment should be arranged according to the localization of the laser damage. Optical coherence tomography angiography also has the potential to help noninvasively detect choriocapillaris damage.

Introduction and Objective: Glaucoma is the leading cause of global irreversible blindness, signed by glaucomatous optic neuropathy related to visual field defect. The purpose of the study is comparing visual field defect examination using HVFA to Amsler Grid in glaucoma patient at dr. Kariadi Hospital. Methods: This is a cross-sectional study. Amsler Grid were performed to the patients who have reliable HVFA at last 6 months and presented as descriptive analytic results. Result: There were 40 eyes involved in this study from 27 patients (15 men, 12 women), 26-68 years old and visual acuity 1/60-6/6. Seventeen eyes showed visual field defect in HVFA and Amsler Grid had average MD - 24.97 dB, CDR 0.89 and RNFL thickness 51.74. We found that 11 eyes didn’t showed in both of examination had average MD -8.06, CDR 0.63 and RNFL thickness 103.23 and those parameters are significantly different to the 17 eyes before (p<0.05). Data from 12 eyes that showed visual field defect only one of examination (9 only in HVFA and 3 in Amsler Grid) didn’t show difference statistically each other. Conclusion: HFVA and Amsler Grid seemed to be comparable in detecting visual field defect in advanced glaucoma.

Objective. To describe a case of acute zonal occult outer retinopathy (AZOOR) in an active duty patient.Methods. In this paper we studied fundus photographs, optical coherence tomograph, Humphrey visual field 30-2, fundus autofluorescence images, fluorescein angiograms, and electroretinography.Results. Exam findings on presentation: a 34-year-old American Indian female presented with bilateral photopsias, early RPE irregularity, and an early temporal visual field defect. Progression RPE damage and visual field defect along with ERG findings support final diagnosis of AZOOR.Conclusion. AZOOR may initially be identified as a broader category of disease called the “AZOOR complex of disorders”. Specific visual field defects, ERG results, and clinical exam findings will help distinguish AZOOR from other similar disorders.
