Purpose. To evaluate changes in corneal sensitivity and subbasal nerve density after pterygium excision. Methods. This prospective\ntrial included 22 eyes with nasal primary pterygium and 18 controls. Corneal sensitivity was evaluated using a Cochetâ??Bonnet\nesthesiometer in the nasal, superior, temporal, inferior, and center quadrants of the cornea before surgery and 10 days, 1 month,\nand 3months after surgery. The central cornea was analyzed using in vivo confocal microscopy (IVCM) before surgery and 1 and 3\nmonths after surgery. Subbasal nerve density and other nerve parameters were analyzed using NeuronJ. Nerve tortuosity was\nevaluated and graded in individual IVCM scans. The tear film break-up time (TBUT) test and Schirmerâ??s test were performed\nbefore surgery, as well as 1 and 3 months after surgery. All the same tests were performed in the controls. Results. All affected eyes\nshowed a significant increase in corneal sensitivity in the nasal corneal quadrant after surgery when compared with preoperative..........................
Background: Macular hole (MH) is a retinal break in the fovea involving partial or complete dehiscence of the\nneural retinal layers affecting the visual quality by decreasing visual acuity (VA) and visual deformation. We describe\na case of secondary MH associated with submacular hemorrhage (SMH) due to polypoidal choroidal vasculopathy\n(PCV), which showed spontaneous closure.\nCase presentation: A 67-year-old man developed decreased VA in his right eye due to an SMH. The VA was 20/50,\nand monthly intravitreal injection of aflibercept was administered three times. The SMH gradually decreased, and\n10 months later the external limiting membrane was found to be perforated, resulting in MH. The old clot\ndisappeared, and the MH remained for 10 months. Twenty-three months later, serous retinal detachment (SRD)\ninvolving the macula appeared and the MH had disappeared. SRD gradually disappeared, and macular\nconfiguration recovered. VA gradually improved and became 20/20 38 months later.\nConclusion: Dynamic change of the ultrastructure in an unusual case of secondary-developed and spontaneously\nclosed MH was clearly observed. Although the mechanism was unknown, the small diameter size and exudative\nPCV are thought to have contributed to the closure....
Background: In diabetic eyes, various choroidal abnormalities are noted in addition to changes in the retinal\ncirculation, and the risk of increased aqueous flare and retinal thickening after cataract surgery is higher in diabetic\neyes. Inflammation caused by surgery induces breakdown of the blood-retinal barrier and affects the retina, although\nthe influence on the choroid is unknown. Several researchers have evaluated the choroidal thickness (CT) after cataract\nsurgery in patients with diabetes; however, the results are inconsistent. The purpose of this study was to evaluate the\ninfluence of uneventful small-incision phacoemulsification cataract surgery on the subfoveal choroidal thickness (SCT),\nthe central macular thickness (CMT), and aqueous flare in patients with diabetes.\nMethods: This study included 59 randomly selected eyes (33 eyes of patients with diabetes and 26 eyes of control\npatients without diabetes) undergoing small-incision cataract surgery. Among the diabetic eyes, 26 were without\ndiabetic retinopathy, and the remaining eyes had non-proliferative diabetic retinopathy. Aqueous flare, CMT, and SCT\nmeasurements were performed before and at 1 week, 1 month, and 3 months after surgery.\nResults: The postoperative CMT continued to increase significantly until 3 months in both groups. Although the CMT\nwas more in patients with diabetes than in patients without diabetes during the follow-up period, there was no\nsignificant difference between the two groups. The aqueous flare value increased until 3 months after surgery in both\ngroups. Although the increase was significant at 3months after surgery in patients with diabetes, the increase in\ncontrols was not significant. The aqueous flare values differed significantly between the two groups before and at 3\nmonths after surgery. There was no significant within-group or between-group difference in pre- and postoperative\nSCT values.\nConclusion: In diabetic eyes with early stage of retinopathy, even small-incision cataract surgery can induce\nincreased aqueous flare and macular thickening until 3 months, although there is no significant change in the\nchoroidal thickness. Further studies are essential to evaluate choroidal changes after the cataract surgery in\ndiabetic eyes....

Background: To measure the microcirculation change of macula and optic nerve head before and after\nfemtosecond laser assisted laser in situ keratomileusis.\nMethods: In total 45 eyes from 45 subjects, who underwent FS-LASIK during June 2017 to December 2017 in\nGuangdong Provincial Peopleâ??s Hospital, were recruited in this study. Vessel density in macula and optic nerve head\nwere measured by optical coherence tomography angiography before and after transient elevation in intraocular\npressure caused by application of suction ring during surgery.\nResults: Vessel density (VD) at superficial (SCP) plexus of macular region did not differ after surgery (F(3,132) = 1.41,\nP = 0.24), while the deep (DCP) plexus of macular region significantly decreased 1 day after surgery (P = 0.001) but\nreturned to its baseline value 1 month postoperatively (P = 0.1). Vessel density of optic nerve head region had no\nsignificant changes after surgery (F(2.51,95.18) = 0.6, P = 0.59).\nConclusions: A short-term temporary decrease of vessel density at deep layer of macular region was observed in\neyes undergoing FS-LASIK. However, the retinal capillary density went back to preoperative level 1 month after\nsurgery. Therefore, transient IOP spike during FS-LASIK did not cause long-term decline of retinal microcirculation....
Background: The purpose was to describe the Nordic treatment practices and to reach a Nordic consensus for the\ntreatment of sebaceous eyelid carcinoma.\nMethods: The treatment practices data was collected by a questionnaire with 37 questions to the Nordic\noculoplastic surgeons and analyzed. A PubMed MEDLINE database search was done to gather data on the\npublished treatment practices and recommendations. A working group that consisted of in minimum one senior\nconsultant from each leading Nordic University Eye Hospital was assigned. A structured interactive method was\nused to establish the consensus.\nResults: Twenty-four doctors responded to the questionnaire. 23/24 (96%) of the respondents took a biopsy before\nsurgery. Regional lymph node scanning was routinely done by 14/23 (61%) and a systemic screening of a\nmetastatic disease by 13/23 (57%). 6/22 (27%) never took conjunctival mapping biopsies and 12/23 (52%) never\nscreened for Muir- Torre. Respondents used Mohs surgery, frozen section or multi-stage excision with delayed\nclosure, and 5â??6mm was the mostly preferred margin. Sentinel lymph node biopsy was a possible option for 9/22\n(41%) and cryotherapy and Mitomycin C for 6/22 (27%) respondents. 50% of respondents considered radiation as a\ntreatment option. 15/16 (94%) respondents always followed-up their patients, most for 5 years. Two thirds scanned\nregional lymph nodes during the follow-up. Consensus was reached for 18 statements representing three domains:\npreoperative work-up, treatment and follow-up.\nConclusion: Treatment practices differ in between the five Nordic countries which have similar public health care\nsystems. In the article the authors present a Nordic consensus for the treatment of eyelid sebaceous carcinoma....
Background: To assess the long-term outcomes of phacoemulsification and intraocular lens (IOL) implantation in\neyes with uveitis.\nMethods: One hundred and five eyes of 81 patients, who underwent phacoemulsification and IOL implantation\nbetween January 2009 and July 2016, were included in this study. The demographic data, preoperative clinical\nfindings, postoperative outcomes, and intraoperative and postoperative complications were recorded. All collected\ndata and risk factors with regard to visual prognosis were analyzed with the help of the Statistical Package for the\nSocial Sciences version 20.0 software program (IBM Corp., Armonk, NY, USA)........................
