We report a case of corneal deposition of pigments from cosmetic contact lenses after intense pulsed-light (IPL) therapy. A 30-year-old female visited our outpatient clinic with ocular pain and epiphora in both eyes; these symptoms developed soon after she had undergone facial IPL treatment. She was wearing cosmetic contact lenses throughout the IPL procedure. At presentation, her uncorrected visual acuity was 2/20 in both eyes, and the slit-lamp examination revealed deposition of the color pigment of the cosmetic contact lens onto the corneal epithelium. We scraped the corneal epithelium along with the deposited pigments using a no. 15 blade; seven days after the procedure, the corneal epithelium had healed without any complications. This case highlights the importance of considering the possibility of ocular complications during IPL treatment, particularly in individuals using contact lenses. To prevent ocular damage, IPL procedures should be performed only after removing the lenses and applying eyeshields.

The purpose of this article is to compare spectral-domain (SD) and time-domain (TD) optical coherence tomography (OCT) findings in patients with solar retinopathy. Complete ocular examinations and OCT were performed in two patients presenting with acute solar retinopathy soon after observation of an eclipse. Both patients were evaluated with SD-OCT and TD-OCT at the same time. SD-OCT demonstrated characteristic defects at the level of the inner and outer segment junction of the photoreceptors in all the affected eyes and decreased reflectiveness of the retinal pigment epithelium layer. TD-OCT images showed unremarkable findings in two eyes with deteriorated visual acuity. SD-OCT improves diagnosis and assessment of the degree and nature of foveal damage in patients with solar retinopathy and may be an important tool for use in identifying foveal damage not detected by TD-OCT. SD-OCT may be preferable to TD-OCT for confirmation or assessment of the degree of foveal damage in patients with solar retinopathy.

OBJECTIVETo investigate the Influence of risk factors that cause the phototoxic maculopathy by welding arc in occupational welders.

METHODSWe examined randomly a group of 86 male occupational welders 172 eyes from some local metal manufacturing enterprise from August 2010 to December 2013. The ophthalmologic examination which the participants underwent thorough including the best visual acuity, fundus examination by the supplementary lens, fundus photography, and the high definition optical coherence tomography (OCT) scan. All participants of this study underwent thorough the medicine examined by a specialist of occupational who prior to the OCT. All the subjects were divided into groups according to age, protection degrees , length of service, operating time . The incidences of phototoxic maculopathy were compared within groups. The subjects was divided randomly into the lutein group and the placebo group. The examination including the best visual acuity, serum lutein concentrations, macular pigmentoptical density (MPOD), Contrast and glare Sensitivity.

RESULTS(1) The total incidence of phototoxic maculopathy is 32.0%. (2) The incidences of phototoxic maculopathy in the strict protection group, the randomed protective group and the nonprofessional protection group were respectively 21.4%, 36.7%, 53.6%. The incidence in the strict protection group was lower than the other two groups, the incidence was the highest in the nonprofessional protection group, and the difference was statistically significant. (3) The longer length of service, and operating time , the more incidence of phototoxic maculopathy develop. (4) The lutein group prior to the placebo group at the best visual acuity, serum lutein concentrations, macular pigmentoptical density (MPOD), Contrast and glare Sensitivity.

CONCLUSIONThe risk factors of phototoxic maculopathy in male occupational welders are the length of service, operating time, protection degrees and the lutein assistantly. The incidence of phototoxic maculopathy occurs regardless of age.

PURPOSE: To report the clinical outcomes of deep anterior lamellar keratoplasty (DALK) when sterile gamma-irradiated acellular corneal tissues (VisionGraft) are used in combination with amniotic membrane transplantation (AMT) for intractable ocular surface diseases. METHODS: The medical records of fifteen patients who had DALK with AMT were retrospectively reviewed. Indications for surgery included ocular burn, bacterial keratitis, herpes simplex virus keratitis, corneal opacity with Stevens-Johnson syndrome, Mooren's ulcer, idiopathic myxoid degeneration of corneal stroma, and recurrent band keratopathy. DALK was performed using partial-thickness acellular corneal tissue and a temporary amniotic membrane patch was added at the end of the operation. RESULTS: All cases that underwent DALK with AMT became epithelialized within 2 postoperative weeks. Twelve patients showed favorable outcomes without graft rejection, corneal opacification, or neovascularization. The other three grafts developed corneal opacification and neovascularization, and required additional penetrating keratoplasty (PK). Unlike the results of previous PKs, there were no graft rejections and the graft clarity was well-maintained in these three cases for at least 8 months after PK. CONCLUSIONS: DALK using sterile acellular corneal tissues in combination with AMT may be a good therapeutic strategy for treating intractable ocular surface diseases because of lowered immune rejection, fibroblast activation, and facilitation of epithelialization. Furthermore, DALK can help stabilize the ocular surface, prolong graft survival, and may allow better outcomes when combined with subsequent PK.

Here, we report the case of a patient who sustained Nd: YAG laser macular injury with subsequent 6 year follow-up evaluation. A 23-year-old female was accidentally exposed to a Q-switched Nd: YAG laser without protective goggles. Upon initial evaluation, the best-corrected visual acuity of her affected eye was 20/100 OD. Fundoscopic examination revealed a macular laser burn and vitreous hemorrhage. Corticosteroids, in the form of 60 mg prednisolone, were administered orally with a 10 mg per week taper. Nineteen days following exposure, fundoscopic examination revealed a distinct epiretinal membrane which resolved within six months. The best-corrected visual acuity of the affected eye remained 20/100 OD. This clinical course is similar to those of previously reported cases including vitreous hemorrhage and subsequent epiretinal membrane formation. However, visual acuity did not recover despite spontaneous regression of the epiretinal membrane and at 6 year follow-up, there was neither choroidal neovascularization nor macular hole formation.
