This is a case presentation of a very bizarre open globe trauma with anterior segment foreign body-fishing hook stuck in the cornea and iris. Complications due to this kind of eye trauma might be very hazardous and with serious impact on visual function. We are representing our approach and experience of three step management of this kind of eye injury: first-extract the foreign body, close and reconstruct the eyeball, second-fight inflammation, and third-restore the visual function by cataract surgery.

AIM: To record aberrations with a corneal topographic device on the anterior surface of the cornea at different time-points prior to wearing and following discontinued use of rigid gas permeable (RGP) contact lenses. The effect of wearing RGP on the anterior surface of the cornea was discussed to provide guidance for clinical refractive error ***: The study objects were 24 eyes from 24 patients. All patients underwent identical examination procedures prior to lens use, as well as afterwards, including slit-lamp examination, non-contact tonometer measurement, computer optometry and corneal curvature measurement, subjective refraction test, and corneal topography analysis. The patients wore contact lenses everyday for 1 month and then discontinued. Corneal topographies were recorded at certain time points of 30 minutes, 1 day, 3, 7 and 14 days following ***: Total corneal aberration at each time point following discontinued use of RGP contact lenses was less than the time point prior to use. Detailed results were as follows: root mean square (RMS) (pre)=(1.438± 0.328)μm, RMS (30 minutes) =(1.076 ±0.355)μm, RMS (1 day) =(1.362 ±0.402)μm, RMS (3 days) =(1.373 ±0.398)μm, RMS (7 days) =(1.387 ±0.415)μm, and RMS (14 days) = (1.430±0.423)μm. Results showed that at 30 minutes after discontinued use of RGP contact lenses, almost all 2 ndand 3 rd-order aberrations change. Quadrafoil Z10 and spherical Z12 of the 4 th-order were also changed. Alterations to Z5, Z6, and Z12 at 1 day after discontinued use were significant differences compared with the time period prior to RGP use: Z5 and Z6 decreased, and Z12 increased slightly. Z5 and Z6 remained decreased at 3 days after discontinued use, but Z9 and Z10 continued to increase and Z12 returned to levels prior to RGP use. At 14 days after discontinued use, all aberrations were notsignificantly different from the values prior to ***: The use RGP contact lenses greatly reduced total aberration of th

AIM: To evaluate the effect of torsional mode phacoemulsification on central corneal thickness, corneal endothelial cell density, and morphology in eyes with/without pseudoexfoliation(PEX) ***: Fourty-two consecutive patients with and42 patients without PEX as a control group scheduled for cataract surgery was studied. Phacoemulsification, using OZi L IP system, was performed with quick chop technique. Using noncontact specular microscopy, the central endothelial cell density(ECD), coefficient of variation, percentage of hexagonal cells, and the central corneal thickness(CCT) were evaluated preoperatively and postoperatively at 1, 7 and 30 ***: The ECD in PEX syndrome was statistically significantly lower than that in the control group preoperatively and postoperatively(P ≤0.001).Percentage change in ECD was statistically significantly higher in PEX than that in control group after surgery follow up(P ≤0.04).There was no statistically significant difference between both groups comparing percentage of hexagonal cells and coefficient of variation in the cell size before and after the surgery. At 1 and 7d after surgery, percentage change in CCT was statistically significantly higher in PEX group than that in the control group(P ≤0.041).CONCLUSION: Although torsional mode phacoemulsification and intraocular lens(IOL) implantation provided a safe and favorable surgical outcome in patients with/without PEX, torsional phacoemulsification led to significantly higher ECD loss in the PEX group than that in the control group during the whole follow up *** addition, more corneal swelling in the PEX group than that in the control group during the early postoperative period has indicated that the corneal endothelium, in presence of PEX endotheliopathy, seems to be more susceptible to the effects of phacoemulsification surgeryin eyes with PEX. The increased risk of anterior chamber manipulations in patients with PEX should be taken into account for an incr

·AIM:Toevaluatethevisualfunctionevolutionofretinal pigment epithelial(RPE) tears in patients with age-related macular degeneration(AMD) according to type of occurrence [spontaneous or secondary to anti-vascular endothelial growth factor(anti-VEGF) injection] and the topographic location of the tear after a two-year followup period.·METHODS: A total of 15 eyes of 14 patients with RPE tears in exudative AMD were analyzed retrospectively at the University eye clinic of Trieste. Inclusion criteria were: patient age of 50 or older with AMD and RPE tears both spontaneous occurring or post anti-VEGF treatment. Screening included: careful medical history,complete ophthalmological examination, fluorescein angiography(FA), indocyanine green angiography(ICG),autofluorescence and infrared imaging and optical coherence tomography(OCT). Patients were evaluated every month for visual acuity(VA), fundus examination and OCT. Other data reported were: presence of PED,number of injections before the tear, location of the lesion.·RESULTS:Meanfollow-up was24wk(SD±4wk). Atotal of 15 eyes were studied for RPE tear. In 6 cases(40%),the RPE tears occurred within two years of anti-VEGF injections the others occurred spontaneously. In 13cases(86.6%), the RPE tear was associated with pigment epithelial detachment(PED). In 7 cases(46.6%), the RPE tear occurred in the central area of the retina and involved the fovea. Two lesions were found in the parafoveal region, six in the extra-macular area. In all cases visual acuity decreased at the end of the follow-up period(P <0.01) independently of the type or the topographical location of the lesion.·CONCLUSION: RPE tear occurs in exudative AMD as a spontaneous complication or in relation to anti-VEGF injections. Visual acuity decreased significantly and gradually in the follow-up period in all cases. No correlation was found between visual loss and the type of onset or the topographic location of the tears.
